Abstract
The author has been working in the energy based models in Fatigue over the past 30 years. This paper is a review of this approach. In the case of fatigue crack initiation, initial models based on dislocation kinetics are reviewed. As a recent application, the models developed in the microelectronics applications are presented. In the case of fatigue propagation, recent developments of the model developed by the author are highlighted. It is shown that most effects attributed to crack closure can be successfully described based on Energy concepts. It is proposed that two fundamental modes of crack growth exist
- one based on cycle by cycle crack growth by striation formation at moderated growth rates,
- second based on a step by step growth at low growth rates.
Based on these facts, a unique crack growth model is proposed that permits the description of fatigue crack growth covering 7 decades, irrespective of the environment. In the case of variable amplitude loading, the energy based analysis shows a similar evolution , based on the existence of two modes of crack growth. The model is extended to fatigue of elastomers – where it is shown that hysteretic energy describes the effects of frequency and the load ratio. A viscoelastic model is developed and it can be shown that specific aspects of elastomer fatigue, such as the strain induced crystallization can be described by energy concepts. Finally multi-axial fatigue behavior in an elastomer is successfully described based on the energy model.

Abstract
Artificial Intelligence is applied for prediction and calculations of unknown values of data or coordinates. Decision makers, academicians, researchers, advanced-level students, technology developers, and government officials will find this text useful in furthering their research exposure to pertinent topics in AI, computer science, numerical analysis or operations research and assisting in furthering their own research efforts in these fields. Proposed method, called Two-Points Smooth Interpolation (TPSI), is the method of 2D curve interpolation and extrapolation using the set of key points (knots or nodes). Nodes can be treated as characteristic points of data for modeling and analyzing. The model of data can be built by choice of probability distribution function and nodes combination. TPSI modeling via nodes combination and parameter γ as probability distribution function enables value anticipation in AI, risk analysis and decision making. Two-dimensional curve is extrapolated and interpolated via nodes combination and different functions as continuous probability distribution functions: polynomial, sine, cosine, tangent, cotangent, logarithm, exponent, arc sin, arc cos, arc tan, arc cot or power function.

Abstract
In stereolithographic additive manufacturing (STL-AM), 2-D cross sections were created through photo polymerization by UV laser drawing on spread resin paste including nanoparticles, and 3-D models were sterically printed by layer lamination. The lithography system has been developed to obtain bulky ceramic components with functional geometries. An automatic collimeter was newly equipped with the laser scanner to adjust beam diameter. Fine or coarse beams could realize high resolution or wide area drawings, respectively. As the row material of the 3-D printing, nanometer sized metal and ceramic particles were dispersed into acrylic liquid resins at about 60 % in volume fraction. These materials were mixed and deformed to obtained thixotropic slurry. The resin paste was spread on a glass substrate at 50 μm in layer thickness by a mechanically moved knife edge. An ultraviolet laser beam of 355 nm in wavelength was adjusted at 50 μm in variable diameter and scanned on the spread resin surface. Irradiation power was changed automatically for enough solidification depth for layer bonding. The composite precursors including nanoparticles were dewaxed and sintered in the air atmosphere. In recent investigations, ultraviolet laser lithographic additive manufacturing (UVL-AM) was newly developed as a direct forming process of fine metal or ceramic components. As an additive manufacturing technique, 2-D cross sections were created through dewaxing and sintering by UV laser drawing, and 3-D components were sterically printed by layer laminations with interlayer joining. Though the computer aided smart manufacturing, design and evaluation (Smart MADE), practical materials components were fabricated to modulate energy and material transfers in potential fields between human societies and natural environments as active contributions to Sustainable Development to Goals (SDGs).

Abstract
There exist various kinds of modern cyber attacks bringing about many network failures over the Internet. Actually, the countermeasures preventing authenticated network users from being attacked by these cyber attacks seem to be case-by-case, Therefore, it is much better for the authenticated network users to be provided with more generic and integrated countermeasures having universal effects on the Internet. This is the reason why we had better classify modern cyber attacks from the point of view of the network theory and investigate the mutual relations between a certain cyber attack and another one. Here we can show several problems which remain to be solved for the purpose of constructing the systematic classification of cyber attacks as the following:
1. Problem asking which network segments cyber attacks originate in, local segments or remote ones.
2. Problem asking which layer of the OSI Reference Model is based on, the datalink layer, the network layer, the transport layer, and so on.
3. Problem asking whether cyber attacks can evolve maliciously or not.
4. Problem asking whether or not a cyber attack is compatible jointly with another one.
5. Problem asking whether or not a newly born hybrid cyber attack can bring about some newly born synergetic malicious effects which have never been observed yet with any of factorial cyber attacks.
In this talk, we introduce some hybrid cyber attacks which has been more threatening by artificial joint combination of a cyber attack with another one.

Abstract
This article presents numerical simulations for nonlinear mixed convection heat transfer in an enclosure divided into two immiscible regions comprising a non-conducting Newtonian viscous fluid and an electromagnetic viscous nanofluid. An interfacial stress condition is employed at the junction between the two immiscible fluid zones. The coupled transport equations for both a Newtonian fluid and a Newtonian electromagnetic nanofluid are formulated, rendered dimensionless and then solved numerically with finite difference method adopting the efficient Southwell Over-Relaxation method subject to appropriate boundary conditions. The influence of pertinent parameters including the Grashof number, Brinkman number, Hartmann number, electric field load parameter, nanoparticle solid volume fraction in addition to different nanoparticles and base fluid material properties on the thermo-convection flow characteristics are discussed. The results indicate that flow rate is boosted with increasing convective and viscous dissipations, and electric field load parameter and it is depleted with greater Hartmann number and solid volume fraction reduce the flow rate. Significant elevation in both velocity and energy is produced with increasing electric load parameter (both short and open circuit cases). An increment in Grashof number decelerates the flow adjacent to the left plate and accelerates the flow at the opposite wall. The combined action of electrical and magnetic field exerts a more dramatic influence on transport characteristics compared with thermal buoyancy (Grashof number). By adding different nanoparticles (e.g. aluminium oxide, copper oxide and graphite oxide) and using alternative base fluids (blood, water and engine oil), more noticeable modifications in heat and momentum characteristics are achieved with copper oxide nanoparticles. The study finds applications in nano-doped electromagnetic hybrid fuel cells, medical flow processing (electromagnetic blood flow meters), sensing systems in chemical engineering etc.

Abstract
Heat transfer of fluids is very important to many industrial heating or cooling equipments. Convective heat transfer can be enhanced passively by changing flow geometry, boundary conditions or by enhancing the thermal conductivity of the working fluid. An innovative way to improve the thermal conductivity of fluids is to introduce suspended solid nanoparticles and ribs. In the last years several investigations have been accomplished to evaluate the convective heat transfer enhancement in nanofluids and ribs. Moreover, ducts with non-circular cross sections have been extensively studied by several investigators and today are widely adopted in many thermal device applications.
In this paper a numerical investigation on laminar forced convection flow of a nanofluid, water–alumina nanoparticles, in a mini duct with triangular cross section is accomplished with the lower heated surface with transversal ribs. A uniform heat flux on the bottom surface of the heat sink is applied and a mixture model approach is employed to simulate the nanofluid flow. The analysis is performed for a three-dimensional combined conductive-convective heat transfer in a square section with triangular duct, at steady state regime.
Results are presented in terms of temperature and velocity distributions, surface shear stress and heat transfer convective coefficient, Nusselt number and required pumping power profiles for different nanoparticle volume fractions. Comparison with results related to the fluid dynamic and thermal behaviors are carried out in order to evaluate the enhancement, with respect to the base fluid, due to the presence of nanoparticles for the different volumetric concentration values.

Abstract
Recently the FDA has tightened and increased the assessment and acceptance criteria making it potentially more difficult and expensive to bring new RBCs storage systems to market. Although the regulatory agencies are to be commended for focusing on the safety of new therapies and devices for patients, there are concerns that the regulatory requirements for RBC storage systems have become excessive and are hindering progress. Technology developers are unwilling to take on the risk that a random poor quality RBCs component could jeopardize the success of licensure tests and clinical trials of their new blood storage systems and their significant financial investment. The researches has proved that now of magnetite nanoparticles are able not only to considerably reduce hemolysis, and thereby prolong storage time of the blood’s heparinized, influence on activity of adenosinetriphosphateses of erythrocytes, regulated transmembrane exchange, but also to extracorporeally influence on cellular apoptosis. The above was the basis for the choice of the theme of this study, devoted to the learning of the use of nanotechnology to correct the functional activity of red blood cells at the storage stages at a positive temperature. The main purpose of the first stage of the study is to develop a simple and practical method of additive modernization of preservation solutions that does not violate the compliance requirements, improves the quality, efficiency and safety transfusion of red blood cells. It was established that saline NaCl which had previously been processed by magnetite nanoparticles (ICNB) had a marked membrane-stabilizing effect, inhibits haemolysis and increasing the sedimentation stability of preserved RBCs. The complex analysis of the obtained data allowed to determine the primary mechanisms effect of the saline NaCl which had previously been processed by ICNB on the preserved RBCs. The proposed method of additive modernization of preserved RBCs was adapted to the production process. The optimisation results were obtained in creating a simple and practical method of additive modernization of preservation solution that does not violate the compliance requirements, improves the quality, efficiency and safety transfusion of RBCs.

Abstract
The steady flow and heat transfer over a thin needle with variable wall temperature using Casson nanofluid is studied. The conservation equations are then reduced to coupled nonlinear ordinary differential equations by means of similarity transformations. The resulting reduced equations are solved numerically by adopting shooting technique and bvp4c algorithm available in MATLAB software. The Tiwari and Das model is incorporated to modulate the nanofluid. The metallic nanoparticles such as gold, copper, silver and diamond are suspended in blood (base fluid). The velocity, temperature, skin friction coefficient and Nusselt number are computed and presented in graphical and tabular forms. The presence of Cassion parameter boosts the velocity, but declines the temperature. The Nussult values are increased using nanofluid in comparison with the regular fluid. Numerical solutions are validated with the literature for limiting conditions and are in good agreement.

Abstract
Hybrid nanofluids are prepared by blending two different kind of nanoparticles in the same basefluid to have greater thermophysical, optical, rheological, and morphological properties. Hybrid nanofluids are projected to replace simple nanofluids due to quite a number of reasons such as wide absorption range, lower extinction, high thermal conductivity, low pressure-drop, and low frictional losses and pumping power as compared to the mono nanofluids. Hybrid nanofluids have been tested for various applications like solar collectors, photovoltaic thermal applications, electronic component thermal management, photovoltaic thermal management, machine cutting, engine applications, and automotive cooling.This presentation will lead to further projects in different research.

Abstract
The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) is an Indian law that aims to guarantee the ‘right to work’ and ensure livelihood security in rural areas by providing at least 100 days of guaranteed wage employment in a financial year to every household whose adult members volunteer to do so unskilled manual work. This flagship programme was started during 2006, almost all Indian States and UTI were effectively implemented MGNREGA for upliftment of rural population and eradication of poverty. During COVID19 pandemic crisis many urban unemployed youths were migrated to the rural population and they are actively participated in MGNREGA to maintain the livelihoods of their families. The Government of India has increased the budget allocation > 60% especially for urban migrants and rural unemployed youths in FY2020. An amount of Rs. 60,000 crores were allocated for MGNREGA at national level. In Karnataka State, approximately 44.86 lakhs rural unemployed youths and urban migrants were benefited this programme in FY 2020 which is the highest in the last five years. In the interest of National economic policy and programme implementation, the present study attempt to assess the impact of MGNREGA programme and how it can supports to the livelihoods of their migrant families of unemployment youths during COVID 19 pandemic crisis. A pilot based survey was conducted in the selected districts of Karnataka State; a total 120 urban migrant respondents were interviewed through pretested and tested questionnaires in accordance with standard operating protocol (SOP). Asper the research findings, the mean age of the respondents was 34.55 with SD 1.22 years .The participation level of Male was (84.0 %) And female was (16.0%). (45.0%) of respondents were completed UG and Post-graduation degree and (2.5 %) awarded higher degree Ph.D. The mean men days were 194 days with average wage of 287 Rupees at the higher rate. (95%) of the respondents were spent earned wage for purchasing of food grains, cloths and children education etc. An economic wage index of MGNREGA in rural population was 54.56 units per person it was found to be statistically significant (p=0.001, modified kappa agreement k is 0.86). Summing of the present study concludes that, the MGNREGA is one of the successful programmes; it provides the social and economic security for urban migrants and rural youths. Finally, based on the research findings and practical experience, it has also been suggested that a high rise in MGNREGA wages could even lead to the possible exclusion of the poorest of the poor in Rural area, the scheme became lucrative even for the above poverty line.

Abstract
Through the use of a novel distributed optical strain sensing (DOS) technique, it has been determined that such a technique can add value not only to the performance and behaviour of ground support systems but also provides an indication of the quality and consistency of the grout that is used within an instrumented fully grouted rock bolt ground support system. Unlike conventional, discrete strain measurement methods, the optical technology captures a distributed strain profile along the length of an optical fiber. This is akin to sampling at a spatial resolution of 0.65 mm whereby a discrete measurement is captured at each 0.65 mm interval along the entire length of a ground support system. This paper builds on previous observations utilizing additional examples (as part of the larger research program) where material flaws, gaps and voids were detected during the testing stage of fully grouted rock bolt systems that were being tested with a view of determining an optimized embedment length. After testing, the rock bolt support system specimens were cut open and a forensic, visual assessment validated the DOS results. The use of the fiber optic technique made it possible to capture complex support behaviour not before captured by conventional means of instrumenting rock bolts. The technique also can provide insight into the type of rock bolt installation that is being conducted and not only determine the effectiveness of the bolt system (i.e. the use and effectiveness of mechanical anchor, quality of grout) but also optimize the support design. The DOS technique has a tremendous potential to play a significant role in quality control with respect to the performance of such ground support systems.

Abstract
Municipal solid waste management (MSWM) has become one of the most complex global environmental issues for urban areas in various countries. It is a very complex system, and misuse of any technology may pollute soil and water with chemicals and lead to climate change. This paper examines MSWM through circular economy, technologies, policies, and participation of all stakeholders in developed and developing countries. Investigations were undertaken to understand the factors and barriers that affect MSWM and the reasons why many countries are unsuccessful in this area. The study found that MSWM has many stakeholders and the municipalities that are directly responsible for this sector are subject to social, political, institutional, financial, economic, and technical factors, in addition to the availability of land. A number of developed countries have achieved important results in this sector. For developing countries, they must move to smart waste management, which includes solid waste prevention, minimization, separation at source, reuse and recycling; and to apply the circular economy approach to their waste policies as it improves sustainability and ultimately leads to improvements in economic and environmental performance. When adopting any technology, it must take into account climate change, appropriate infrastructure, pollution control system, maintenance, development, and following up on the requirements and regulations of the country. It also requires changes in perception and performance and the involvement of all stakeholders at all levels. Achieving this will not be easy, therefore, integrated MSWM strategies must be developed to be applied in the short, medium and long terms.

Abstract
The flow and heat transfer of micropolar nanofluid sandwiched between porous medium in a horizontal channel is analyzed. The model is developed to study the behavior of micropolar nanofluid taking into account the solid volume fraction and porous parameter. Using Darcy’s law for porous medium and Tiwari Das model for nanofluid governing equations are obtained. The governing equations are solved using regular perturbation method. Water and glycerin is taken as base fluid and copper as nanoparticles for the analysis. Analysis is carried out on the flow characteristic for different values of Grashof number, Prandtl number, Eckert number, Reynolds number, porous parameter and solid volume fraction. It is found that Grashof number, Prandtl number, Eckert number promotes the flow. Reynolds number and material parameter suppress the flow. Moreover for different physical parameter, the rate of heat transfer, mass flow rate and skin friction is illustrated in table form. The solvent viscosity for air, water and glycerin, the cell rotation on the flow is presented in tabular form for 20% and 40% concentration.

Abstract
Non-Newtonian flow from a wedge constitutes a fundamental problem in chemical engineering systems and is relevant to processing of polymers, coating systems, etc. Drived by such applications, the numerical solutions are computed for convective boundary layer flow of incompressible micropolar nanofluid from a two-dimensional wedge. Viscous dissipation and heat sink effects are included. Employing suitable similarity transformations, the balance law equations are reduced to first order nonlinear ordinary equations. The Runge-Kutta-Fourth order method is accepted to find the numerical solutions of the reduced equations. Primary and secondary shear stress, wall couple stress, Nusselt number, microrotation velocity, and temperature were computed for the effect of nanoparticle volume fraction, vortex viscosity parameter (micropolar rheological), Eckert number (viscous dissipation), Falkner-Skan (pressure gradient) parameter, micro-inertia density, and heat sink parameter for different types of nanoparticles. It was observed from the study that the temperature and thermal boundary layer thickness are both suppressed with increasing wedge parameter and wall heat sink effect, which is beneficial to temperature regulation in polymer coating dynamics. Also, both primary and secondary skin friction components were reduced with increasing wedge parameter. Nusselt number was also enhanced substantially with greater wedge parameter and nanoparticles.

Abstract
As per sources from Forbes, 84% of the world’s energy is met by fossil fuels whereas the remaining 16% demand is taken care of by non-fossil fuels like solar, wind, biomass energy etc. Global leaders are trying their best to reduce the fossil fuel dependency so as to stride towards a greener and cleaner future. Hydrogen is considered by many to be the “Future Green Fuel” and a very promising contender to the conventional fuels which are available currently. The reason for hydrogen being chosen as an alternative owes to its remarkable properties such as exceptionally high energy content per unit mass (142 MJ/Kg, 3 times as that of gasoline), low mass density, and massive environmental and economic upsides. The current automotive industry is researching efficient and environment friendly approaches to the production of hydrogen, storage, purification and usage. Fuel Cell Electric Vehicles (FCEV) are becoming increasingly popular among the leading automotive companies all over the world. It involves a combination of Hydrogen storage system, battery system, motor and Fuel cell PMC. Present technologies of hydrogen production include Steam reforming of natural gas (48%), partial oxidation of heavy hydrocarbons (30%), partial oxidation of coal (18%) and electrolysis (4%). Extensive research is being conducted on improving the efficacy of hydrogen storage using various methods like high pressure gas cylinders, liquid hydrogen storage in cryogenic tanks, Metal hydrides, liquid chemicals, porous materials(carbon: 50-150K), carbon nanomaterials, glass microspheres etc. Out of these, usage of metal hydrides for hydrogen storage seems to be quite advantageous. A literature survey has been conducted by gathering data and figures from around 50 significant research articles and a comparison is drawn, the efficacy of metal hydride hydrogen storage systems is reviewed. A case study for future prospects of hydrogen storage in fuel cell vehicles has been discussed in this review article.

Abstract
Inverted perovskite solar cells (PSCs) have gained rapid progress and increasing research interests in recent years. Nowadays, poly (triaryl amine) (PTAA) is widely used as the hole transport layer (HTL) in inverted PSCs for its favorable highest occupied molecular orbital (HOMO) energy level (−5.2 eV), excellent carrier mobility, and low-temperature solution processability. However, its intrinsic hydrophobic property hinders the growth of high-quality perovskites on the PTAA film, which is one of the main obstacles that limits the further development of inverted PSCs. Herein, a donor-acceptor-donor type organic molecule, 4,4',4''-(1-Hexyl-1H-dithieno [3',2':3,4;2'',3'':5,6] benzo[1,2-d] imidazole-2,5,8-triyl) tris (N, N-bis(4-methoxyphenyl) aniline) (denoted as M2), is employed to modify the surface of PTAA. The PTAA/M2 composite hole transport layer facilitates the growth of perovskite films with enhanced crystallinity and carrier mobility. Using PTAA/M2 instead of pure PTAA as HTL, the power-conversion efficiency of inverted PSC increases from 18.7% to 20.2%. Furthermore, its operational stability is also significantly enhanced. Our methodology carves out a novel path for improving the efficiency and photostability of inverted PSCs.

Abstract
The rapid growth during the last decade has been accompanied by active construction, which in some instances neglected the impact on the environment and human activities. Policies to promote the rational use of electric energy and to preserve natural non-renewable resources are of paramount importance. Low energy design of urban environment and buildings in densely populated areas requires consideration of wide range of factors, including urban setting, transport planning, energy system design and architectural and engineering details. The focus of the world’s attention on environmental issues in recent years has stimulated response in many countries, which have led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for heating, lighting, cooling, ventilation and hot water supply. However, exploitation of renewable energy in buildings and agricultural greenhouses can, also, significantly contribute towards reducing dependency on fossil fuels. This will also contribute to the amelioration of environmental conditions by replacing conventional fuels with renewable energies that produce no air pollution or greenhouse gases. This study describes various designs of low energy buildings. It also, outlines the effect of dense urban building nature on energy consumption, and its contribution to climate change. Measures, which would help to save energy in buildings, are also presented.

Abstract
Ductile iron camshafts low alloyed with 0.2 and 0.3 wt % vanadium were produced by one of the largest manufacturers of the ductile iron camshafts in México “ARBOMEX S.A de C.V” by a phenolic urethane no-bake sand mold casting method. During functioning, camshafts are subject to bending and torsional stresses, and the lobe surfaces are highly loaded. Thus, high toughness and wear resistance are essential for this component. In this work, two austempering ductile iron heat treatments were evaluated to increase the mechanical properties of tensile strength, hardness, and toughness of the ductile iron camshaft low alloyed with vanadium. The austempering process was held at 265 and 305°C and austempering times of 30, 60, 90, and 120 min. The volume fraction of high-carbon austenite was determined for the heat treatment conditions by XRD measurements. The ausferritic matrix was determined in 90 min for both austempering temperatures, having a good agreement with the microstructural and hardness evolution as the austempering time increased. The mechanical properties of tensile strength, hardness, and toughness were evaluated from samples obtained from the camshaft and the standard Keel block. The highest mechanical properties were obtained for the austempering heat treatment of 265 °C for 90 min for the ADI containing 0.3 wt %V. The tensile and yield strength were 1200 and 1051 MPa, respectively, while the hardness and the energy impact values were of 47 HRC and 26 J; these values are in the range expected for an ADI grade 3.

Abstract
When you look closely, Nature is nanotechnology at its finest. From a single cell, a factory all by itself, to complex systems, such as the nervous system or the human eye, each is composed of specialized nanostructures that exist to perform a specific function. This same beauty can be mirrored when we interact with the tiny physical world that is the realm of quantum mechanics.When solids are reduced to the nanometer scale, they exhibit new and exciting behaviours which constitute the basis for a new generation of electronic devices.Nanotechnology for Microelectronics and Optoelectronics outlines in detail the fundamental solid-state physics concepts that explain the new properties of matter caused by this reduction of solids to the nanometer scale.It is also a rapidly expanding field. Scientists and engineers are having great success making materials at the nanoscale to take advantage of enhanced properties such as higher strength, lighter weight, increased electrical conductivity, and chemical reactivity compared to their larger-scale equivalents.

Abstract
Emerging deficit in the demand and supply of fossil fuels reframed the critical need of its alternative energy source from renewable energy, where solar to hydrogen production is one of the main research interests in today’s energy sector. Plentiful material combinations have been reported in-search of the ideal photoelectrodes, with limited success due to their poor efficiency and aqueous stability. We have successfully employed ‘nanophotonics’ developed efficient and stable photoanodes (TiO2 nanofibers, carbon quantum dots, plasmonics) and photocathodes (2D Materials) which act as ‘artificial leaf’ to harvest solar energy and convert it into chemical fuel i.e. hydrogen with maximum efficiency of 4.8% and stability of >10 hrs. Further, the trending practice of flexible electronics is a strategic-aiding aspect for the speedy-propagation of miniaturized & flexible devices. Motivated by this, we herein demonstrate polypyrrole polymer decorated laboratory filter paper (PFP) as photoanodes (PAs) which mimics the ‘natural leaf’ for artificial solar light harvesting and photoelectrochemical (PEC) water splitting. The in-situ polymerized polypyrrole polymer coated onto filter paper (i.e. for the fabrication PFP-PAs), has spherical morphology and average particle size of the order ~15 nm as portrayed by HR-TEM. The results manifest excellent photoanodic PEC activity of these PFP-PAs, yielding a photocurrent density of ~9.5 mA/cm2 (at 1.23 V vs. RHE) under 1-sun irradiation. Moreover, the robustness of these flexible PFP-PAs is also visualized by testing their stability for more than ~160 minutes in alkaline conditions, in the three-electrode benchtop device for hydrogen production. The present study also opens up the avenue for the exploration of flexible photoelectrodes for PEC water splitting employing ‘nano-photonics’ which could redefine the use of papers for ‘green hydrogen’ production in fulfilling the future energy demand as an alternative clean fuel. Keywords: Photoelectrodes, artificial leaf, hydrogen, photoelectrochemical, water splitting

Abstract
Additive Manufacturing (AM) - technologies of layer-by-layer building up and synthesis of objects.Multiple additive manufacturing techniques are presented today in the world. Nowadays there are different kinds of AM realization, from the electron beam, a laser source with respective filler material to wire arc technologies. Among them wire arc additive manufacturing (WAAM) the most promising for producing large metal components for the construction industry. Firstly, it conditioned by the cost-effectiveness of the WAAM. The heating source in such a scheme is an electric arc. For filler material is used commercial welding wire. The combination of these two factors gives valuable benefit and gain before high-energy laser or electron beam tools.
Direct energy deposition attracts more and more attention in the additive manufacturing design research. Considering GMAW as the most widespread it should be taken into account the operating mode. This means special welding current, voltage, welding speed, etc. In complex all above mentioned welding parameters affecting welding thermal cycle. WCT is the most important measure of welding process effectiveness due to it determines structure formation and thus properties of the final product. In this connection determination of the optimal welding parameters is the key point for successful additive manufacturing process dosing. The modern development of the welding power source offers pulse technology implementation. Commonly known pulse parameters are the amplitude and duration of the pulse and pause put additional complexity into the design process. Nevertheless, the application of special project methods such as the Taguchi algorithm, makes this task solvable. A number of studies have demonstrated the effectiveness of pulse technology in the traditional welding process. Namely, PCGMAW improves stabilization of the arc, decrease spattering, increase penetration depth, etc. Further development of pulsing technologies in GMAW provides additional improvement of the pulse combination, thus obtained double pulse. Application so-called low frequency (f<25Hz) pulse arc welding (PAGMAW) provides opportunities for metal crystallization process controlling. Obviously, a good combination of the modern pulse technologies in GMAW will bring exciting benefits for additive manufacturing promotion into large-scale production.

Abstract
Three Dimensional (3D) porous carbon materials are highly desirable for electrochemical applications owing to their high surface area and porosity. 3D architecture and porosity of the carbon support materials allow the reactant molecules to access more numbers of electrochemical active centres and simultaneously facilitate removal of the product formed during the electrochemical reactions. Herein, we have prepared nitrogen-doped entangled graphene framework (NEGF), decorated with the NiFe-LDH nanostructures by in-situ solvothermal method followed by freeze-drying at high pressure and low-temperature conditions. The freeze-drying method helped to prevent the restacking of the graphene sheets, and the formation of high surface area nitrogen-doped entangled graphene (NEGF) supported NiFeLDH. The incorporation of NEGF has significantly reduced the overpotential for the electrochemical oxygen evolution reaction (OER) in 1 M KOH solution. This corresponds to an overpotential reduction from 340 mV for NiFe-LDH to 290 mV for NiFe-LDH/NEGF to reach the benchmark current density of 10 mA cm−2 . The preparation of the catalyst is conceived through a low-temperature scalable process.

Abstract
In this work, for the first time, a nanocomposite composed of carbon nanotubes and lacunary polyoxotungstates (LPOT/CNT) was synthesized. The nanocomposites were used as a sorbent for the dispersive micro solid-phase extraction (D-µSPE) of five organophosphorus pesticides (OPPs) (i.e. fenthion, diazinon, fenitrothion, profenofos, and phosalone) from water and fruit juice samples. The extracted OPPs were quantified via gas chromatographyflame ionization detector (GC–FID). The main factors affecting the D-µSPE of the OPPs, such as the desorption conditions, amount of sorbent, and extraction time, were investigated, in detail. The LPOT/CNT nanocomposite shows a synergistic effect and its extraction efficiency is higher than intact CNTs and LPOTs. Under the optimized conditions, the D-µSPE-GC-FID method showed linearity from 0.02 to 200 ng mL− 1 , limits of detection in the range of 0.007–0.02 ng mL− 1 . The precision expressed as relative standard deviations (RSD%) ranged from 3.3 to 4.7%. The D-µSPE-GC-FID based on LPOT/CNT sorbent was used for the extraction of OPPs in fruit juices (apple juice and peach juice) and real water samples (wastewater and river water) and with relative recovery values of 94.2–99.6%.
