Abstract

ZBLAN glass is one of the heavy metal fluoride glass systems. It has a wide range of transmission from the near UV to the mid IR. Most importantly, ZBLAN optical fiber has a theoretical attenuation coefficient an order of magnitude lower than fused silica optical fiber. Unfortunately, ZBLAN tends to crystallize during fiber drawing and these crystallites scatter light increasing the attenuation coefficient above that of fused silica optical fiber. It was discovered that processing and drawing ZBLAN optical fiber in microgravity suppressed crystallization. It was also discovered that the same effect occurs when an axial magnetic field is used. This talk will focus on the experimental procedures used in both cases as well as the results. Future work will also be discussed.

Abstract

Layered double hydroxides (LDHs) structure consists of a positively charged metal hydroxide layer and interlayer anions for charge compensation of the cationic layer. The general formula [MII1-xMIIIx(OH)2] [(An−)x/n·mH2O], where MII is a divalent cation such as Ni2+, Mg2+, and Zn2+, MIII is a trivalent cation such as Al3+, Fe3+, and Cr3+, and An- is an anion such as CO32-, Cl-, and OH-. The internl redox reactions of the transition-metal-containing LDHs is a driving force used for diverse electrochemical reactions, therefore, LDHs have been studied as anion exchangers, catalysts, and electrode materials. 

In this presentation, the synthesis of LDHs and their characterization for diverse electrochemical reaction will be discussed. LDHs powders are usually prepared by the co-precipitation process and used as anion exchange membranes (OH- conductors) and electrode material (electrolizers). LDHs can be also prepared as  thin-film form, of particular application for electrochromic devices, in which the transition metal redox can be used in their optical properties.

Abstract

Under the aegis of unique properties, polyurethane has always been an immutable material for plenty of industries. Polyurethane has numerous advantages namely; lightweight, noise reduction, impact resistance, durability and cost efficient fabrication. Polyether based integral skin polyurethane foam parts are widely used automotive industry due to alpha plus performance in absorbing sound waves and transmission loss properties of the material. Fillers play large role to enhance specific properties of materials and make the product profitable. As a filler, calciumcarbonate (CaCO3), is one of the most widely used filler in polymer industry because it is feasible, allows cost efficiency and improves mechanical properties. On the other hand, it is not able that when CaCO3 is co oparetes with water, CaCO3particles prefer to aggregate during compounding with the polymer matrix due to hydrophilic nature of CaCO3. In this  study CaCO3particles were modified from hydrophilic to hydrophobic with oleic acid treatment to prevent agglomeration and increased is persion quality of fillers in polymer matrix. Acoustic properties of  polymer matrix which contain so leicacid  modified CaCO3 is investigated and compared with same version of polyurethane with no filler and polyurethane composite which contains same amount of non-modified  CaCO3.TheIdealpercentage of filler content is determined as % 4wt of polyether based polyolforeach samples. Additionally FTIR, DSC and TGA of samples are investigated. Results revealed that polyurethane composite with oleic acid modified CaCO3 performed enhanced sound absorption and transmission loss properties instead of the rest of the sample groups.

Abstract

Colloids, known as volume expanders, have been used as resuscitation fluids for hypovolemic shock for decades, as they create an increase plasma oncotic pressure and expand intravascular volume. However, recent studies show commonly used synthetic colloids have adverse interactions with human biological systems in vitro and in vivo. In this work, we design a lowfouling amino (N)-oxide based zwitterionic polymer as an alternative volume expander with improved biocompatibility and efficacy. We demonstrate that the polymer possesses anti-fouling ability, resisting cell interaction and deposition in major organs, and is rapidly cleared via renal filtration and hepatic circulation, reducing risks for long-term side effects. In vitro and in vivo safety studies showed absence of adverse effects on hemostasis or acute safety risks. Finally, we show that, in a head-to-head comparison with existing colloids and plasma, the zwitterionic polymer serves as more potent oncotic agents for restoring intravascular volume in a hemorrhagic shock model. Our design of N-oxide-based zwitterionic polymers may lead to the development of alternative fluid therapies to treat hypovolemic shocks and for improving fluid management in general.

Abstract

Transition of hydrocarbon to clean energy economy can occur with electrocatalytic water splitting. Water splitting is considered as a promising path for energy conversion and storage in which electrocatalysts play a crucial role. This led researchers to focus on development of novel and efficient catalysts for electrolysis. The design of electrocatalyst with active sites, chemical kinetics and bubble generation is focus of interest. Also, the bubble diffusion and path plays a key role. The developed catalysts has to be operated at higher loads compared to the current operating loads to meet future energy demands. A highly porous structure with easy charge-transfer, constant bubble generation and easy diffusion facilitates the stability of electrocatalyst at higher loads. The development of various porous structured catalyst, their electrochemical reactions, and post-mortem results after long-term tests at higher loads will be discussed.

Abstract

Removal of 100 to 1,000 gigatonnes of CO2 this century may be needed to achieve deep decarbonization and avoid exceeding the 1.5°C climate target. Nano wonder materials and nanotechnology is playing key role. Graphene has found its use in numerous industrial applications due to its unique properties. While its impermeable and conductive nature can replace currently used anticorrosive toxic pigments in coating systems, graphene can be an important component as a next-generation additive for many industrial applications (1). Graphene, a sheet of carbon atoms bound together in a honeycomb lattice pattern, is hugely recognized as a “wonder material” due to the myriad of astonishing attributes it holds. It is a potent conductor of electrical and thermal energy, extremely lightweight chemically inert, and flexible with a large surface area. It is also considered eco-friendly and sustainable, with unlimited possibilities for numerous applications.

The current bottlenecks in using graphene & graphene oxide are the availability of cost-effective, high-quality materials from graphite and their effective incorporation into the product matrices. 

On overcoming these factors, graphene may attract significant demands in terms of volume consumption. Graphene can be produced on industrial scales and cost-effective top-down routes such as chemical, electrochemical, and/or high-pressure mechanical exfoliation. Graphene depending on end applications can be chemically tuned and modified via functionalization so that easy incorporation into product matrices is possible.  This talkable to discuss(Siva progress in chemistry short bio 1981 to 2021) and Graphene advanced production methods and their impact on the quality of graphene produced in terms of energy input and quality.

Abstract

The use of renewable energy sources is a fundamental factor for a possible energy policy in the future. Taking into account the sustainable character of the majority of renewable energy technologies, they are able to preserve resources and to provide security, diversity of energy supply and services, virtually without environmental impact. Sustainability has acquired great importance due to the negative impact of various developments on environment. 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

Li‐ion batteries are the powerhouse for the electronic devices in this modern mobile society, and an enabler of the current communication revolution. Consumers demands advanced electronics and sustainable industries in general. To satisfy these demands, the new generation of rechargeable batteries need to provide much higher specific energy density than the actual technology. Commercial Lithium Ion Batteries (LIBs) consist of Lithium Metal Oxides as positive electrodes and graphite as a negative electrode, this system has energy density values ca. 250 WhL-1.

Lithium sulfide (Li2S) provides a promising route for lithium storage due to high theoretical specific capacity (1166 mAh g−1)andspecific energy(2600Whkg_1). This positive electrode material can be coupled with lithium-free negative electrode to develop high-energy-density batteries. There are still formidable challenges with it (e.g., low conductivity, high overpotential, and irreversible polysulfide diffusion) and associated fabrication processes (e.g., low reversible capacity), which have prevented the realization of high electrochemical utilization and stability.However, the complex synthesis methodof Li2S–carbon composites restrains the large-scale productivity. We propose a method to synthesize a Li2S based nanocomposite cathode material by dissolving Li2S as the active material, polyvinylpyrrolidone (PVP) as the carbon precursor, and graphene oxide (GO) as a matrix to enhance the conductivity, followed by a co-precipitation and high-temperature carbonization process. This work may shed fresh insight into bridging the huge gap between high energy and safety of rechargeable cells for feasible applications.
