The utilization of lignin, an abundant and renewable bio-aromatic source, is of significant importance. In this study, lignin oxidation was examined at different temperatures with zirconium oxide (ZrO)-supported nickel (Ni), cobalt (Co) and bimetallic Ni-Co metal catalysts under different solvents and oxygen pressure. Non-catalytic oxidation reaction produced maximum bio-oil (35.3 wt%), while catalytic oxidation significantly increased the bio-oil yield. The bimetallic catalyst Ni-Co/ZrO produced the highest bio-oil yield (67.4 wt%) compared to the monometallic catalyst Ni/ZrO (59.3 wt%) and Co/ZrO (54.0 wt%). The selectively higher percentage of vanillin, 2-methoxy phenol, acetovanillone, acetosyringone and vanillic acid compounds are found in the catalytic bio-oil. Moreover, it has been observed that the bimetallic Co-Ni/ZrO produced a higher amount of vanillin (43.7% and 13.30 wt%) compound. These results demonstrate that the bimetallic Ni-Co/ZrO catalyst promotes the selective cleavage of the ether β-O-4 bond in lignin, leading to a higher yield of phenolic monomer compounds.

The formation of functional bacterial amyloids by phenol-soluble modulins (PSMs) in Staphylococcus aureus is a critical component of biofilm-associated infections, providing robust protective barriers against antimicrobial agents and immune defenses. Clarifying the molecular mechanisms of PSM self-assembly within the biofilm matrix is essential for developing strategies to disrupt biofilm integrity and combat biofilm-related infections. In this study, we analyzed the self-assembly dynamics of PSM-β1 and PSM-β2 by examining their folding and dimerization through long-timescale atomistic discrete molecular dynamics simulations.

Biofilm formation on medical devices has become a worldwide issue arising from its resistance to bactericidal agents and presenting challenges to eradicating biofouling adhesion, especially in biological fluids. Metal-phenolic networks have been demonstrated as a versatile and efficient strategy to prevent biofilm formation by endowing medical devices with prolonged antifouling and antibacterial activities in a one-step surface modification. In this study, we report a simple and environmentally friendly method using coordination chemistry between copper ions (Cu) and dopamine-containing copolymer to fabricate metal-phenolic network-based coatings.

Cured-in-place-pipe (CIPP) technology has begun to be adopted for drinking water pipe repairs, and limited information exists about its drinking water quality impacts. CIPP involves the manufacture of a new plastic pipe inside a buried damaged pipe. In this study, the chemical composition of the raw materials and CIPP water quality impacts were examined.

A novel polyimide-bridge covalent organic framework-based (PI-COF) hybrid was synthesized through simple green chemistry between PI-COF and MCM-NH monomers as a pH-sensitive anticancer curcumin (C) delivery system. The synthesized nanohybrid was crystalline in nature with an improved surface area and pore volume compared to the base COF, certified by powder X-ray diffraction spectroscopy and Brunauer-Emmett-Teller technique. Kinetically controlled and sustained curcumin release profiles were investigated using the as-prepared curcumin-loaded drug delivery systems (C@DDSs) in neutral and acidic pH media.

The burgeoning field of materials science is currently witnessing a paradigm shift toward the utilization of renewable plant biomass as a viable chemical source for the production of sustainable materials. This trend is substantiated by a significant corpus of recent experimental and theoretical research focused on the synthesis and property analysis of such polymers. Within this context, polybenzoxazines stand out as a pioneering class of thermosetting polymers, distinguished by their exceptional thermal and mechanical characteristics, coupled with the feasibility of synthesizing their precursor monomers from eco-friendly, renewable resources, including plant phenols and furfurylamine.
