Photoreforming of biomass presents a promising approach for sustainable H production by utilizing renewable solar energy under ambient conditions. However, its application is often limited by the poor solubility of biomass-derived substrates. Herein, this challenge is addressed by synthesizing hydrophilic, electron-rich pyridine-based glycopolymers via reversible addition-fragmentation chain transfer polymerization, followed by deacetylation of glucose- and maltose-based segments.

Sequence-controlled polyester-based alternating copolymers have attracted significant interest due to their biocompatibility, biodegradability, closed-loop recyclability, and hydrolytic degradability, offering broad potential in biomedical and sustainable materials. Among the available strategies, regioselective ring-opening polymerization (ROP) of asymmetric cyclic di(thio)esters and cyclic(ester-amide)s has emerged as a promising approach for constructing alternating copolymers with precise sequence- and stereo-control, structural diversity, and tunable properties. This review classifies asymmetric cyclic monomers into two categories: (1) monomers with two aliphatic ester bonds, where regioselectivity is mainly dictated by steric differences and typically requires tailored metal catalysts; and (2) monomers with chemically distinct reactive sites (e.

For recovering whey soybean protein (WSP) from soybean whey wastewater (SWW) in food industry, a foam separation method for separating WSP by using temperature-responsive Janus sheets (MF-JNSs-PN) as foam stabilizer was established. MF-JNSs-PN was prepared by grafting the temperature-responsive polymer PNIPAM onto one side of the sheet inorganic material using BSA@Cu(PO)-MF as the template. MF-JNSs-PN has a good ability to stabilize the foam due to inducing the hydrophilicity and hydrophobicity transition by adjusting the temperature.

The degradation of colorless tetracycline hydrochloride (TCH), a widely used antibiotic, is a significant environmental concern due to its persistence in aquatic systems. The zinc sulfide (ZnS) nanoparticle fabricated melamine-formaldehyde polymer (MFP)-based nanocomposite (ZnS-MFP) was prepared via a hydrothermal polymerization method, followed by surface modification through a simple precipitation route. The degradation of TCH through photocatalysis adheres to pseudo-first-order kinetics with a significantly faster rate under natural sunlight than under artificial bulb light.

Fly ash (FA) landfills are overflowing with materials, and unexplored waste streams like waste spent garnet (WSG) and waste foundry sand (WFS) are often dumped in onsite storage spaces, limiting land availability for future use and exacerbating environmental concerns related to waste disposal. Therefore, this research proposes recycling FA to produce reclaimed FA (RFA) as a binder, replacing 40-60% of ground granulated blast furnace slag (GGBFS) and 30-50% of river sand (RS) with WSG and WFS to produce geopolymers. The performance of geopolymers was assessed under different curing regimes, including ambient-temperature curing (ATC), ambient-temperature water curing (AWC), high-temperature curing (HTC), and high-temperature water curing (HWC).
