Abstract: Quantum computing is newly emerging information-processing technology which is foreseen to be exponentially faster than classical supercomputers. Current quantum processors are nevertheless very limited in their availability and performance and many important software tools for them do not exist yet. [..] Read more

Abstract: We have targeted in this study the contact deposition of copper on the silicon surface of a solar cell. We show the different drawbacks encountered in the process and present some solution and ways to obtain satisfactory copper-based contact. [..] Read more

Abstract: The wide range of applications of AuNPs is related to their different shapes and sizes, which are dependent on the synthesis process and reaction parameters. Therefore, the optimization of a novel and highly efficient approach to chitosan substrate decoration by AuNPs via covalent bonding using dialdehyde cellulose (DAC) is presented here. [..] Read more

Abstract: Gold nanoparticles (AuNPs) find application in various areas depending on their properties, shape and size distribution, which are mainly influenced by the preparation conditions. Moreover, due to the trend in recent years, toxic reducing and stabilizing agents are being abandoned during the synthesis of AuNPs, and alternative substances for one-pot green synthesis are being sought.

Abstract: Recently investigated colloidal quantum dots, constructed from chalcogenide materials became very attractive for researchers due to their applications in quantum dot solar cells. In this work the electron and heavy hole states in spherical and ellipsoidal CdSe/CdS colloidal core-shell quantum dot, which is wildly used in solar cells technologies, have been investigated theoretically in the frame of finite element method calculations.

Abstract: The process of electrospinning can be influenced strongly by a change in the electrical conductivity of the spinning solution. Plasma-mediated modification of organic polymer powders is known to alter their surface polarity. [..] Read more

Abstract: Expanded graphite is produced on commercial scale using various intercalating agents and physical expansion conditions. Little is known about the different effects these processing conditions may have on the electrical, thermal, and mechanical properties when used in composites since these may cause the materials to behave differently.

Abstract: Due to the high surface to volume ratio, the particles’ surface properties modification defines its properties in general, which is crucial for their use. From this point of view, plasma processing or high temperature annealing can be considered as the universal techniques for efficient modification of materials in the form of powder. [..] Read more

Abstract: Exterior surface characteristics of the submerged hollow fiber (HF) membranes are believed to have a significant impact on the fouling rate within the filtration process in a bioreactor used for wastewater treatment. Most of the interactions among the organics, particulate particles, and microorganisms occur at the interface of the membrane surface and activated sludge (AS). [..] Read more

Abstract: The main aim of the study is to investigate the performance of ultra-thin polymer composite nanofiber-embedded membranes for efficient CO2 transport. To fabricate these membranes, a combination of polyvinyl alcohol (PVA) and a specially selected modifier that supports CO2 transport was used in addition to polyamide 6 nanofiber layer.

Abstract: The ceramic composite filament for 3D printing of high-strength ceramics by the FFF/FDM method was prepared in an extruder from feedstock in the form of granules containing micro- and nanoparticles of zirconium oxide and with a low content of plasticizer. An optical and thermal analysis of the filaments and the comparison with commercially produced filament for 3D printing of ceramics were performed. [..] Read more

Abstract: Currently, great emphasis is placed on air quality and the presence of pollutants, whether on toxic substances (NH3 or CO), substances that reduce the quality of life (CO2) or chemical vapors from industries (acetone or ethanol). Attention is therefore focused on new gas-sensing materials enabling detection even at low (up to room) temperatures with sufficient response and short reaction time.Here, we investigate the suitability of hydrogen-terminated nanocrystalline diamond (H-NCD) films and their heterostructures with molybdenum disulfide (MoS2), graphene oxide (GO), reduced GO (rGO), thiolfunctionalized GO (SH-GO), or gold nanoparticles (Au NPs) for gas sensing applications.

Abstract: The shift towards sustainable energy sources has generated a growing need for materials that can effectively produce and conserve alternative fuels. While platinum is known for its outstanding catalytic properties in hydrogen evolution, its scarcity presents a significant challenge. [..] Read more

Abstract: As air pollution is becoming a severe problem, especially in developing countries, it is necessary to seek the protection. It is well known that fine particle matter is the cause of some respiratory diseases, but recently, it has been found that they can also absorb aerosols with viruses and facilitate their easier spreading, thanks to their big area volume ratio.

Abstract: Cation active chitosan was studied as the active substance incorporated into an inert hydrogel to affect its transport and barrier properties. The inert hydrogel was based on thermo-reversible agarose which can be prepared in defined shape and size required for the mathematical description of studied transport. [..] Read more

Abstract: Graphitic carbon nitride is one of the most studied photocatalysts for environmental applications as well as for the production of hydrogen. Its band gap at 2.7 eV means that the photocatalytic activity of this material can be activated with the light of wavelength 460 nm and lower. [..] Read more

Abstract: Functionalization of materials is a very common procedure because it allows materials to acquire new properties. The inspiration for developing a coating based on catechol comes from a protein derived from mussels that remain on rocks under conditions of constant exposure to water. [..] Read more

Abstract: This study deals with a long-term stability study of biodegradable polycaprolactone (PCL) nanofibrous dressings for skin applications, an important parameter for the storage of materials prior to actual application. Nanofibrous materials generally have suitable properties for regenerative medicine and tissue engineering, such as high porosity with small pore size, high areal density of fibers, large specific surface area, and these materials are able to mimic natural skin extracellular matrix with their fibrous structure.

Abstract: Tissue engineering aims to develop materials that enhance biological activity and promote tissue healing and regeneration. One promising approach is to functionalize nanofibrous materials with antimicrobial substances, such as lipophosphonoxin (LPPO), and use water-soluble polymers like polyvinyl alcohol (PVA) to incorporate bioactive molecules into fibers.
