Summary: In this study, polycaprolactone (PCL) and type collagen (COL) were electrospun to oriented nanofibrous mats, and chitosan (CS) and COL molecules were then deposited on the mats by layer-by-layer self-assembly (LBL) technique. The successful fabrication and modification were confirmed through zeta potential, FT-IR analysis, and XPS measurement. Changes in surface morphology and increased surface roughness were observed during the LBL process, leading to improved mechanical properties and enhanced cell viability on the mats. Cell adhesion and growth along the direction of nanofiber arrangement in LBL modified mats provide an effective strategy for controlled cell growth.

Summary: Chirality plays a crucial role in the synthesis of biomolecules and the development of life. However, the understanding of the relationship between the intrinsic chirality of engineered materials and biological responses is still in its early stages. This Perspective article discusses three classes of intrinsically chiral engineered materials, namely carbon dots, metal-based materials, and patterned geometries, and highlights the differences in design, structure, and function between enantiomers as well as the effects of intrinsic chirality on biological processes. It also addresses safety concerns, challenges, opportunities, and future directions for the development of intrinsically chiral materials.

Summary: An investigation on the conductivity of individual carbon nanofibers (CNFs) and their networks reveals that the microscale CNF networks exhibit good electrical interconnections and a homogeneous current flow. The macroscopic conductivities are strongly correlated with the microscopic results. The presence of highly resistive surface fractions limits the conductivity of CNFs and their networks, and this limitation can be reduced by increasing the carbonization temperature. This study contributes to the understanding of the microstructual models of CNFs and their electrical properties, particularly electron percolation paths.

Summary: In this study, carbon nanofibers were successfully fabricated from a special polyacrylonitrile copolymer/graphene nanoplates composite via electrospinning and subsequent stabilization and carbonization processes. The morphological and structural properties of the composite nanofibers were found to be influenced by the concentration of graphene nanoplates, with higher concentration leading to finer and more crystalline fibers.

Summary: This study provides insights into the influence of sulphate addition on the glass forming properties of SiO2-P2O5-K2O-MgO/CaO/MgOCaO systems. The results show that only the system containing MgO can obtain amorphous materials. The addition of SO3 increases the glass transformation temperature and decreases the vitreous state transformation range and onset of the crystallization process. The precipitate K2SO4 exists in the studied materials regardless of the composition of the base glass.

Summary: In this study, a novel Pt-free counter electrode (CE) material, based on hierarchical carbon nanofibers/carbon nanotubes/NiCo (eCNF/CNT/NiCoNP) ternary nanocomposites, was proposed for dye-sensitized solar cells (DSSC). The nanocomposites were obtained through a combination of the electrospinning technique and CCVD synthesis. The morphology, surface chemistry, and structural ordering of the nanocomposites were found to have significant correlations with their electrocatalytic activity. The DSSC with eCNF/CNT/NiCoNP-electrodes exhibited higher efficiencies compared to Pt-based devices, demonstrating the excellent performance of the prepared CE.

Summary: The study investigated using waste beet pulp shreds as a sorbent to remove crystal violet dye from water and explored the antimicrobial properties of the resulting material. Equilibrium and kinetic studies were conducted to examine the sorption process of crystal violet dye on beet pulp shreds. The Langmuir isotherm model showed the best fit, with a sorption capacity of 28.07 mg/g. Kinetic studies and FT-IR analysis confirmed that the sorption process of crystal violet dye on beet pulp shreds is chemical. The obtained material demonstrated growth inhibition of selected microorganisms, with Escherichia coli and Pseudomonas aeruginosa being more resistant than Candida albicans and Staphylococcus aureus.

Summary: The purpose of the study was to determine the conditions for preparing CF to obtain carbide composites with favorable mechanical response. The study investigated the relationship between the interfacial properties of fiber/polymethylsiloxane composites and the mechanical properties of resulting fiber/carbide composites. The CF/resin interfacial strength was modified using different methods, and the study revealed different bonding characteristics at the fiber/resin and fiber/ceramics interfaces. Silanization of CF significantly improved the interfacial shear strength, while reducing the flexural properties of the carbide composites. The most promising treatment method for CF in PIP-based ceramic composites was modification with PyC, which resulted in enhanced interfacial shear strength, flexural strength, and work to fracture compared to unmodified CF.

Summary: This study describes the vibrational properties of the anticancer drug batimastat (BB-94) as an inhibitor of extracellular matrix metalloproteinase and its adsorption on a silver roughened electrode surface using surface-enhanced Raman spectroscopy (SERS). The research reveals that the applied electrode potential and excitation wavelengths greatly influence the molecule-metal interface. By calculating molecular geometry and Raman frequencies, the nature of vibrational modes is clarified, and it is found that certain parts of the molecule interact with the metal surface, resulting in enhanced SERS signal. Additionally, different adsorption species or metal complexes on the surface could contribute to the observed SERS spectra.
