Abstract: This study examines the rheological properties and technological characteristics of five types of AzureFilm filament made from polylactic acid (PLA), modified with three kinds of wood fillers (bamboo, pine, and cork), as well as poly(p-phenylene pyromellitimide) (PPPI). The filaments underwent multiple processing steps, including grinding, drying, and melting, followed by injection molding. [..] Read more

Abstract: Physical crosslinking of water-soluble polymers is a promising route for creating highly pure and biocompatible hydrogel scaffolds, offering an advantage over methods that use potentially cytotoxic chemical reagents. This study investigated the effectiveness of heat treatment and β-electron irradiation for the physical crosslinking of electrospun nanofibrous scaffolds / hydrogel disks derived from synthetic polymer - polyvinyl alcohol (PVA) and natural polymer - gelatin (GEL), focusing on material stability and cytocompatibility.

Abstract: The use of nanofiber threads as surgical sutures has been proposed as a way to improve the quality of repairs. However, due to the insufficient robustness of current manufacturing methods, it has not been possible to produce and scale continuous nanofiber threads on an industrial scale, and therefore they are not currently available for clinical use.

Abstract: Electrospun poly(ε-caprolactone) (PCL) nanofibers are promising materials for biomedical applications due to their biocompatibility and biodegradability. PCL is a semicrystalline polymer, and its functional properties are strongly influenced by its crystalline-amorphous morphology. [..] Read more

Abstract: Silver nanoparticles (AgNPs) have been extensively investigated for their biostimulatory or toxic effects on microalgae. However, the influence of the inoculum’s developmental stage on astaxanthin biosynthesis in the microalga Haematococcus pluvialis remains largely unexplored. [..] Read more

Abstract: Magnetic resonance imaging (MRI) is a powerful tool for studying nanoparticle biodistribution in vivo. However, conventional approaches usually rely on qualitative assessment from T1-, T2-, or T2*-weighted images. [..] Read more

Abstract: The presented work deals with the analysis of suspensions from two types of zirconium oxide nanopowder and two types of reagents (Disperbyk and Dolapix) suitable for the creation of porous ceramics. In the work, a secondary material - micro methyl cellulose (MMC) was used as a combustion additive, and the stability and rheological behaviour of suspensions with increasing MMC content were observed.

Abstract: Aerogel is a type of material with an expanded three-dimensional network structure, assembled by consistent polymer molecules. Organic aerogels have gained attention in recent years as environmentally friendly materials due to their high porosity, low density, and similar characteristics. [..] Read more

Abstract: Oleic acid (OA) and oleylamine (OAm) ligands are commonly employed to enhance the stability of CsPbBr₃ (CPB) nanocrystals by passivation of the surface defects resulting in the improvement of photoluminescence efficiency, carrier lifetime and the adjustment of electronic properties. Studying the interaction between CPB perovskite and various ZnO surfaces is crucial for understanding the structural, electronic, and optical properties - such as bandgap, charge transport, and binding energy.

Abstract: Two-dimensional (2D) molybdenum disulfide (MoS2) synthesized by Chemical Vapor Deposition (CVD) is essential for scalable electronic and optoelectronic applications. We report a systematic study on the CVD synthesis of MoS2 layers on Si/SiO2 substrates using MoO3 and sulfur powder precursors in a two-zone furnace. [..] Read more

Abstract: Expanded graphite is considered a stepping stone to graphene because it can be easily exfoliated into graphene layers when forming composite materials. It therefore has the potential to significantly improve conductivity and mechanical properties in most composites, as shown in the literature. [..] Read more

Abstract: Metal-fullerene composites represent a specific class of materials exhibiting interesting properties. However, the thin hybrid assemblies are thermodynamically unstable, thus the destructive processes such as thermal annealing can change their structure and properties.In this work, the thermal stability of nickel-fullerene composites was investigated over a broad temperature range.
