Abstract

Recent developments in origami engineering, tensegrity systems, architected materials and mechanical metamaterials suggest a fundamental shift in structural mechanics: mechanical functionality is increasingly generated not only by material composition, but by geometric organization itself.

Origami-based systems derive their behavior primarily from folding kinematics, geometric constraints and programmable motion pathways, while tensegrity structures achieve stability through self-stress states and prestressed force networks. Although traditionally treated as separate research domains, modern duality-based approaches reveal deep mathematical and mechanical connections between infinitesimal mechanisms in origami and self-stress states in tensegrity systems.

This contribution discusses origami and tensegrity as complementary manifestations of a broader framework of geometrically organized mechanics. Within this perspective, geometry no longer merely defines external form, but actively stores and organizes mechanical behavior, stability, adaptability and energy pathways.

The presentation further connects these ideas to current research on metamaterials, programmable matter, adaptive structures, bioinspired systems and computational design. Particular emphasis is placed on the transition from material-dominated engineering toward structurally programmed functionality, where stiffness, deformation modes and dynamic behavior emerge from topology, geometry and internal organization.

Finally, the work proposes that modern mechanics may increasingly evolve from a science of material properties toward a science of organized geometric states, with important implications for future structural engineering, robotics, smart materials and computational mechanics.

Abstract

MgO is a ceramic oxide with a wide bandgap (7.8 eV), low effective atomic number and

high chemical stability (melting point = 2800 °C), which impacts researchers for exploring

it as a dosimetric material. There are few reports on luminescence dosimetry for undoped and doped MgO due to the lack of reproducibility for the luminescent signal in thermoluminescence (TL), regardless of the synthesis method (i. e. solid state reactions, crystal growth, hydrothermal synthesis, coprecipitation synthesis, and sol-gel). Solution combustion technique is particularly attractive due to its low cost and ability to obtain           high purity materials. According to the antecedents mentioned above, thermoluminescence properties of annealed MgO chemically modified with Gd and Li, obtained by solution combustion (SCS), using glycine as fuel, are presented in this work for the very first time. Characteristic TL glow curves of MgO chemically modified with Gd and Li, annealed powder samples, after being exposed to beta radiation, were obtained, with a main peak located at ~ 360 °C. Moreover, the synthesized phosphor showed remarkable TL dosimetry properties according to the results obtained in this work: Dose response without saturation evidence and a linear trend in the 0.5-16 Gy dose interval. The above-mentioned characteristics place MgO chemically modified with Gd and Li as a promising material for low and medium-dose applications.

Abstract

Biomimicry explores how principles found in nature can inspire the development of advanced technologies, particularly by revealing the remarkable efficiency of matter organization from meso- downto nano-scales. Natural systems -refined over millions of years of evolution- -offer elegant structures that balance performance, adaptability, and resource efficiency. By studying these systems, scientists and engineers gain valuable insights for designing materials with enhanced functionality. Modern laser-based techniques are essential for translating these biological inspirations into engineered solutions. (Ultra)fast and high-precision laser processing enables the replication of complex hierarchical structures found in nature, from micro-scale surface textures to intricated internal architectures. These tools allow for the controlled modification of materials by finetuning laser energy, pulse duration, and scanning patterns, effectively encoding specific structural and functional properties into surfaces or volumes. The integration of biomimicry with laser fabrication opens new frontiers in creating advanced functional materials -a topic that we will explore further-. 1-i.e. shark skins exhibit microscopic riblet patterns reducing drag and promoting hypercavitation effects in fluid flow. These characteristics have inspired engineered surfaces to reduce friction, and enhance performance in marine and transport systems. 2-i.e. hyperelasticity of octopus limbs allowing them to undergo extreme deformation while maintaining functionality; mimicking theses properties enables the development of flexible, resilient materials for soft robotics and adaptive systems. 3-i.e. feathers of owls serve as a model for silent flight, thanks to their unique serrated edges and soft, porous structure that reduce aerodynamic noise. Replicating these features inspires quieter aerodynamic surfacesfor applications ranging from low-noise aircraft components to more efficient wind turbines. 4-i.e. moth eyes exhibit nanoscale surface patterns that significantly minimize light reflection, giving rise to exceptional anti-reflective properties. Mimicking these structures allows the development of optical surfaces with reduced glare and enhanced light transmission, offering promising applications in photovoltaics, sensors, and optical devices.

Abstract

A significant component of our research concerns the development of surface chemistry that reduces bacterial adhesion to materials employed to fabricate catheters and other medical devices.  The interaction of substrates with the components of biological fluids such as urine has constituted a research problem over many years. In this regard, a variety of strategies have been used to attempt an enhancement of biocompatibility with some emphasis being centered on the control of surface free energy and imposition of a plethora of surface coatings. In our work, we are examining the self-assembled monoloyer (SAM) modification of medical grade steel and  polymers employed in various devices. We are working primarily with samples containing relatively high concentrations of E.coli, Pseudomonas, Candida (fungus) and Staphylococcus Aureus both in static and dynamic experiments studied by fluoresence microscopy In particular,we have exmned the interaction of Cnadida Albicnas and Staphylococous Aureus with respect to both time and number of particles for exposure to the modified materials. The various SAMs exhibit distinctly different behaviour in terms of bacterial and fungal interaction and eventuaal biofilm formation. The relevance of the results of our research to the avoidance of bacterial fouling of substraes to produce  biofilms will be evaluated.

Abstract

Water chemical stability, deposition tendency, indirect efficiency of the chemical treatments, available concentration impact on mining limits, sediments to solute ratio, sedimentation partiality, chemical availability of resources, extraction flow cell The concentration of ions, elements at each phase of oil-water mixture as well as the ratio of solute: sediment and sedimentation partiality indicate at one hand the efficiency of the chemical treatment and at another one it indirectly impacts on mining limits and economic of mining. For any oilfield the ratio of the preferable mining methods of the direct and indirect resources are determined. In the article the efficiency of chemical treatment and on base of it is triggered which indirect resources would be extracted and by which methods and technologies. By the series of oilfield experiments at last decades by increasing of water salt stability statistically confirmed by correlation with application of the object oriented chemical treatment. Stabilization effect confirmed for corrosion to sedimentation ratio from 1:0.7 to 1:3. Special attention was paid to unclassical consequences like deposition tendency or sedimentation and tandem sedimentation inducted by sulfides, phosphates and complex ions. The available concentration increasing for few elements and ionic balance of stabilized waters make mining of minor components named, as indirect resources are technically possible and economically backgrounded. The ions at water bone is highly active and chemically available and the extraction flow cell is useful for extraction and brine concentration, but the combination with some additional technologies is preferable. At one side was show good economic way to concentrate of copper, zinc, iron, some heavy and light elements, and anions compounds from flow for transferring to metal or solid phase at second stage of extraction, at another one the decreasing of water corrosion activity is achieved as an indirect positive effect of complex technology.

Abstract

Petroleum-based fillers continue to dominate the production of fiber optic cable gels. With the increased demand for high-speed internet and sustainable telecommunications, the extraction and overuse of non-renewable resources will contribute to increased greenhouse emissions over the next twenty-to-thirty years. This study investigates a transition from petroleum to plant-based, biodegradable materials by evaluating their production and performance efficiency. Plant-based oil gels made from epoxidized soybean or castor oil, engineered through chemical modification will effectively provide moisture blocking and mechanical protection while significantly lowering CO2 emissions. Typical engineering processes would include chemical modification to boost thermal and oxidative stability, thixotropic thickening agents to create a stable gel network, and antioxidants or stabilizers to slow degradation over time. While the chemical modification of plant-based oils can differ due to the amount of double bonds, the similar types of thickening agents and antioxidants remain the same in both petroleum and plant-based processing. Results indicate that this is not only feasible, but will also reduce the carbon footprint without compromising the efficacy of cable performance or signal strength.

Abstract

All human advances have depended on making new materials, and all materials are alloys, i.e. mixtures of several different starting materials or components. So the history of the human race has been the continued invention of new materials by discovering new alloys. Recently a new way of doing this, by manufacturing multicomponent high-entropy alloys, has shown that the total number of possible materials is enormous, so we have lots of wonderful new materials yet to find. And multicomponent phase space contains a surprisingly large number of single-phase extended solid solutions and compounds. The first of these that was discovered are called Cantor alloys, an enormous composition range with a single-phase fcc structure, based on the original equiatomic five-component Cantor alloy CrMnFeCoNi. This talk discusses briefly the history of alloying, the discovery of multicomponent alloys, the structure of multicomponent phase space, and the thermodynamics of multicomponent solid solutions such as the Cantor alloys. It concentrates on the complexity of local nanostructures in such materials, their effect on properties such as atomic diffusion, dislocation slip, recrystallisation, surface catalysis and electron transport, and the resulting outstanding mechanical properties and potential applications, including for corrosion and radiation resistance, and to enhance recycling and re-use.

Abstract

Patient safety depends on making informed decisions regarding the materials, processes, and manufacturing changes associated with medical devices. As biomaterials become increasingly sophisticated and regulatory expectations continue to evolve, manufacturers must bring together materials science, biocompatibility, toxicology, engineering, quality systems, and risk management to support innovation while ensuring patient safety and global regulatory compliance.

This presentation introduces a risk-based framework for evaluating biomaterials and biological safety from product innovation through commercial rollout and ongoing change management. Drawing upon real-world industry case studies, attendees will explore how scientific, engineering, quality, and regulatory considerations can be aligned to support product development and informed decision-making while meeting the expectations of ISO 13485, ISO 10993, ISO 14971, ISO/TS 21726, current FDA guidance, and EU MDR requirements.

Topics include the evaluation of elastomers, adhesives, polymer stabilizers, plasticizers, residual monomers, colorants, particulates, and manufacturing-related constituents, with emphasis on understanding the relationship between material composition, patient exposure, and toxicological risk. Additional discussion will address the application of Threshold of Toxicological Concern (TTC) principles, chemical constituent identification, FTIR material equivalency assessments, supplier and manufacturing change management, worst-case device selection, and the interpretation of biological safety data to support regulatory submissions and product modifications. The presentation will also examine the biological significance of particulates and the value of incorporating particulate assessment into an overall biological safety strategy.

By combining biomaterials science, toxicology, engineering, quality systems, and regulatory strategy within a comprehensive patient-safety framework, this presentation provides scientists, engineers, and regulatory professionals with practical tools to strengthen regulatory defensibility, support innovation, reduce unnecessary testing, and improve patient outcomes through scientifically sound and defensible decision-making.

Abstract

In this presentation, we will focus our attention to the materials used in nerve grafting, especially composite materials based on graphene-related materials. Graphene-related materials are increasingly used in many medical and non-medical applications, alone or associated with specific polymers including collagen, gelatine, chitosan, silk fibroin, etc. Their use is justified especially considering the special biological, chemical, mechanical and electric properties. Looking into the literature, there are several approaches to get nerve grafts, acting not only as a support for the cells but also to take some of the functionalities of the nerves. In nerve regeneration, all these properties are essential and, especially graphene oxide can fulfil all the requested characteristics, including the electric stimulation for the regeneration purpose or the electric triggering capacity for controlling the release rate of the biological active agents loaded into these grafts; the tuneable hydrophil/ hydrophobe ratio, which is especially important in the delivery but also in the biocompatibility; etc.

Abstract

Mechanochemistry has recently emerged as an innovative approach to chemical synthesis, enabling the preparation of a wide variety of organic, and hybrid organic–inorganic materials under conditions that fundamentally differ from those of conventional solution chemistry. This presentation will address mechanochemical transformations of organic molecules and selected inorganic ionic compounds from the perspective of their physical reaction environment: are these transformations truly solid-state processes, or do they require intermediate liquid states, low-melting eutectics, or small amounts of added solvent? These systems will be contrasted with the mechanochemical transformation of transition metal dichalcogenides (TMDCs) into 3-dimensional heterostructures and mixed high-entropy TMDC materials, which represent predominantly solid-state mechanochemical processes. Thus, it appears that mechanochemistry should not be viewed as a single mechanistic category, but rather as a continuum of diverse reaction environments and conditions.
