Summary: The study investigated the production of 1,5-PDO from furfural using a Co-Mg-Al catalyst, which showed superior catalytic activity due to abundant basic sites. The cooperation of abundant hydrogenation sites and basic sites facilitated the conversion of furfural into diols, as demonstrated by in situ diffuse reflectance infrared spectroscopy characterization. The use of layered double hydroxides as the catalyst precursor benefited dispersion of metallic Co particles and development of pore structures.

Summary: The catalytic transformation of biomass-derived polyols into valuable chemicals using renewable carbon resources is an important research area. In this review, the selective conversion of sugar alcohols into mono-alcohols and/or diols is discussed, with a focus on the design and preparation of heterogeneous catalysts with high activity, selectivity, and stability. The metal-metal oxide interaction, catalyst structure-performance relationship, and reaction mechanism for C-O hydrogenolysis are highlighted. The future trends for selective hydrogenolysis of sugars are also discussed.

Summary: The intermolecular condensation of glycerol and aminophenol has been investigated using a milling and microwave-assisted sequential strategy to synthesize a benzoxazinone derivative. Mechanochemical activation prior to the microwave-assisted process enhances the contact between the reagents, improving the conversion of aminophenol. Additionally, the sequential approach allows for tuning the selectivity towards the formation of a benzoxazine derivative with potential applications in various biomedical areas.

Summary: A novel bidentate Schiff base (L) was proposed for the detection of Zn ions in water. The synthesized Schiff base L was characterized and found to exhibit fluorescence quenching in the presence of Zn2+ ion. A modified L-M/SPCE sensor with high sensitivity and selectivity to Zn ions was developed for electroanalytical determination in water.

Summary: This study investigated the possibility of enhancing the antibacterial properties of titanium implants by covalently inserting bioactive ammonium salts onto the surface of titanium substrates. The chemically modified samples showed good resistance against bacterial adhesion, particularly when containing long alkyl chains. The results underscored the importance of chemical functionalization in improving the antimicrobial activity of metal surfaces.

Summary: AnchoisFert, an organic fertilizer made from milled anchovy leftovers and biobased limonene, is found to be highly effective in promoting the growth of Tropea's red onion. It outperforms commonly used organic and chemical fertilizers, contains rich nutrients without antibiotics or antibiotic resistance genes, and can replace conventional organic and inorganic fertilizers. This discovery closes the material cycle for the most fished species in the seas and paves the way for a new class of high-performance organic fertilizers derived from abundant biowaste through a low-cost and environmentally-friendly circular economy process.

Summary: Highly active, selective, and stable titania-based catalytic materials were synthesized using a simple and environmentally friendly microwave-assisted approach. The materials were further modified with metal nanoparticles using a simple chemical reduction method. The synthesized materials exhibited excellent catalytic performance in the reductive amination of furfural towards furfuryl amine, and showed remarkable recyclability after six reaction cycles.

Summary: This study proposes a laboratory-scale biorefinery strategy for orange peel waste (OPW), which includes ensiling, adding biological and chemical supplements, and anaerobic digestion (AD). The strategy successfully preserves the methane potential and stimulates the production of value-added compounds. The solid fraction of OPW, separated after long-term ensiling, retains about 50% of the methane potential of fresh OPW. Semi-continuous AD results in stable methane production even though nutrient supplementation is needed.

Summary: Hybrid hydrogels composed of chitosan (CS) have great potential in bone tissue engineering and regeneration. The addition of polyhedral oligomeric silsesquioxanes (POSS) has been shown to improve the properties of the hybrid composites. In this study, we investigated the effect of different concentrations of POSS on the properties of the final composites and found that the CS/POSS hydrogels have good biocompatibility and controlled drug release ability.

Summary: This research conducted comprehensive experimental investigation on the geotechnical characterization of new synthetic lightweight aggregates (SLAs) composed of reused biomass fly ash and waste plastics. The SLAs were evaluated for their compressibility, creep properties, compaction features, stress-strain-strength behavior, hydraulic conductivity, and water absorbability. The study found that the fly ash-HDPE aggregate had less compressibility compared to the fly ash-LDPE aggregate, and its creep coefficient was comparable to or even lower than that of other recycled materials. The aggregates also exhibited favorable permeability properties and proved to be environmentally sustainable.

Summary: Ni nanoparticle catalysts supported on Vulcan carbon (VCX) were prepared and used for the acceptorless dehydrogenation of primary amines to secondary amines. The best performance was achieved with Ni(A)/VXC with Ni particle size of 11.9 nm at 150 degrees C. This work provides inspiration for further investigation into acceptorless dehydrogenation using non-noble metal catalysts.
