Abstract: This theoretical study continues our previous work on the properties of Fe-doped hexagonal boron nitride (h-BN) [1]. In the first part of our research, the structural and thermoelectric properties were examined following Fe atoms incorporation. [..] Read more

Abstract: Undoped diamond films were synthesized by Hot-Filament Chemical Vapor Deposition (HF-CVD) using gas mixtures containing 5–7 vol.% methanol in hydrogen. The influence of methanol concentration on film morphology, crystallinity and sensing performance was systematically investigated. [..] Read more

Abstract: Sodium dodecyl sulfate (SDS), sodium laureth sulfate (SLES), cocamidopropyl betaine (CAPB) and polyvinylpyrrolidone (PVP) have been chosen as dispersants in preparation of stable water suspensions of carbon nanotubes (CNTs). BET specific surface areas of buckypapers obtained by vacuum filtration of the suspensions are approximately 80 m2/g and do not differ significantly from each other. [..] Read more

Abstract: Detection of hurtful and noxious gases has become more and more crucial for the environmental monitoring, manufacturing/monitoring of industrial products and for human health safety. Into this bargain, an innovative ammonia (NH3) gas sensor based on ternary composites of ZnO/PPy-Ag, deposited in ITO-PET thin film was successfully synthesized via photopolymerization process.

Abstract: The use of a thin solid electrolyte layer on polyethylene (PE) separators has been explored as a potential strategy to mitigate the polysulfide shuttle effect in lithium-sulfur (Li-S) batteries, a phenomenon responsible for significantly reducing their lifespan. While some solid electrolytes, such as LAGP (Li1+xAlₓGe2-x(PO4)3), have demonstrated the ability to effectively suppress the shuttle effect, their brittle ceramic nature limits their application, particularly in flexible electronics.

Abstract: Solid electrolytes (SEs) for sodium-based superionic conductors (NaSICON) were first introduced in 1976 and quickly recognized for their excellent ionic conductivity. While considerable effort has been made to develop thin electrolytes for all-solid-state batteries (ASSBs), only a few sodium-based SEs have been successfully fabricated as thin films.

Abstract: This study provides a description of a simplified, accelerated and economically advantageous method for determining the catalytic activity of carbon compounds based on graphene oxide (GO) and graphitic carbon nitride g-C3N4 during the electrolysis of water. The method proposed in this study for determining the catalytic activity of carbon compounds based on graphene oxide and graphitic carbon nitride is based on measuring the amount of H2 bubbles formed by the process of the dissociation of water on a cathode.

Abstract: The global push for eco-friendly and biodegradable alternatives to conventional plastics has intensified interest in natural polymers for sustainable functional materials. In this contribution, we present a robust formulation for highly sustainable, flexible composite films engineered from a synergistic combination of two abundant polysaccharides, carrageenan (CG) and sodium alginate (SA).

Abstract: The effect of a thin Ni barrier layer on Li diffusion - deposited between the solid electrolyte and the cathode - was investigated using Neutron Depth Profiling (NDP) and complemented by Rutherford Backscattering Spectrometry (RBS) for elemental depth distribution analysis. Half-cells consisting primarily of a LiPON solid-state electrolyte, MoS₂ cathode, and a top Au current collector were fabricated on Ti substrates via ion beam sputtering. [..] Read more

Abstract: Self-cleaning properties of the surfaces of the building materials represent a significant benefit that reduces the operational costs connected to maintenance of the building structures. In principle, the self-cleaning phenomenon can be achieved by three effects: i) hydrophobic, ii) photocatalytic, and iii) a combination of hydrophobic and photocatalytic effects. [..] Read more

Abstract: Amine-functionalized solid adsorbents are key materials for CO2 capture, but their practical deployment is often constrained by energy-intensive, solvent-based and time-consuming preparation methods. This study addresses that challenge by evaluating a solvent-free high-speed shear mixing (DRY) method for preparing amine-loaded adsorbents using ZEOFREE® 600, a commercially available calcium silicate. [..] Read more

Abstract: The aim of this work is the development of a new technology for the production of core-sheath nanofiber yarn based on applying a nanofiber bundle onto a ballooning yarn core in a parallel orientation. In contrast to the currently used perpendicular deposition methods, this concept enables the fibers to be applied at a single point, which is expected to achieve higher cohesion between the nanofiber sheath and the core.

Abstract: Due to increase of glass waste landfills, the alternative strategies of silicon-based glass waste disposal such as a partial replacement for cement and aggregates in concrete are investigated. However, the impurities and contaminants in glass waste complicates its direct use as efficient secondary raw material for sustainable construction applications and compel use of additives or glass surface modifications.

Abstract: Graphitic carbon nitride (g-C3N4) is an intensively studied photocatalyst active in the visible spectrum range. The most commonly used method for g-C3N4 preparation is the thermal polycondensation of melamine at temperatures in the range of 500–600°C, resulting in the so-called bulk g-C3N4. [..] Read more

Abstract: Diamond coatings provide outstanding hardness and wear resistance for cutting tools, however, their application on cemented tungsten carbide (WC–Co) is often limited by insufficient adhesion. This study addresses this challenge by introducing a thin nanocrystalline-diamond (NCD) buffer layer to enhance the adhesion of subsequently deposited microcrystalline-diamond (MCD) coatings.
