Summary: The triboelectric nanogenerator (TENG) is a newly developed technology that converts mechanical energy into electricity. In this study, a natural rubber (NR) filled with cellulose fiber (CF) and Ag nanoparticles was developed as a triboelectric material. The presence of Ag nanoparticles in the NR-CF@Ag composite enhances the energy conversion efficiency of TENG, resulting in significantly improved power output. This research demonstrates the potential for developing a biodegradable and sustainable power source by converting mechanical energy into electricity.

Summary: This study investigated the profiles, mechanical performance, and structure of hybrid coatings cured at different cure windows. It was found that elevating curing temperature can affect the cross-linking reactions and breaks of Si-O-Si bonds, leading to improved mechanical performance of the coatings. The presence of FTIR band at 1658 cm(-1) and the rearrangement of Si-O-Si bonds were identified as key factors influencing the adhesion and mar resistance of the coatings cured at 250 degrees C, 1 h.

Summary: Researchers have prepared amine in-situ hybrid SiO2 aerogels with hierarchically porous structure, which overcome the limitations of high cost and low CO2 adsorption capacity in silica aerogels. The micropores constructed by the steric hindrance effect of long organic chain from bis[3-(triethoxysilyl)propyl]amine facilitate faster and more uptake of CO2. The obtained aerogels have high amine content, high specific surface area (up to 579.63 m2/g), and high pore volume, resulting in a fascinating CO2 capture ability of 6.57 mmol/g at 273 K, significantly higher than other silica-based aerogels.

Summary: Nanofibers present challenges to modern material science, and the combination of organic and inorganic components in the form of hybrid nanofibers is an area that has yet to be fully explored. This study presents a patented process for preparing the first purely hybrid organic-inorganic organosilane nanofibers, which exhibit unique properties due to the strong covalent bonds between silicon and carbon. These nanofibers were successfully prepared without the use of additives commonly employed in the preparation of other types of nanofibers.

Summary: In this study, cotton fibers were successfully functionalized with ZnO/Cu2+ and ZnO/Cu-0 hybrid systems via a hydrothermal routine. The functionalized fibers showed changes in crystallinity index and adequate fixation of ZnO nanoparticles and reduction of copper ions. Antimicrobial tests confirmed that the multifunctional fibers exhibited bactericidal activity against both Gram-negative and Gram-positive bacteria under electromagnetic irradiation (440-480 nm). Furthermore, the functionalized fibers improved the self-disinfection capability and UV blocking properties of wipes.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
