Summary: The production of cellulose reinforced bio-composites offers a sustainable alternative to petroleum-based plastics, while utilizing waste agro-industrial residues for lignocellulose biorefinery can help combat environmental pollution. Research shows that using deep eutectic solvents to extract lignin, functionalize cellulose into nanocrystals, and use them as bio-fillers can lead to the successful production of bioplastic films with excellent mechanical and moisture barrier properties.

Summary: The environmental problems caused by fossil fuels, the world's largest energy source, are well known. Additionally, nonrenewable energy sources such as petroleum are running out. In order to move towards a safe and sustainable future, major research labs around the world are trying to find breakthroughs in producing green biopolymers using natural/renewable agmresidues as a substrate. Using non-edible lignocellulosic biomass as a feedstock for biopolymer production does not interfere with food security, reduces emissions, and decreases stubble burning. Micro- and macroalgae are organic sources of biopolymers that have a wide range of applications in pharmaceutical, packaging, food, and biomedical fields.

Summary: The increase in population and urbanization has led to a significant amount of food waste, and effective waste management is a major concern. However, the perishable nature and high moisture content of food waste are major obstacles to cost-effective valorization. Bioconversion of food waste into value-added products is an environmentally friendly and economically viable approach to address these issues. Targeting the production of multiple products can provide a greater solution.

Summary: Tropical fruit wastes are important sources of food and nutrition in tropical countries. With the modernization of agriculture, there has been an increase in tropical fruit production, resulting in a higher abundance of fruit waste. Typically, this waste is considered without economic value and ends up in landfills. However, recent observations have shown that tropical fruit waste can be utilized to produce value-added products such as compost, phytochemicals, food products, and biofuels. This review aims to understand the composition of major tropical fruit wastes and their potential for conversion and valorization, including the role of microbes and future perspectives in waste utilization.

Summary: We have developed a new catalytic system for preparing amides using tandem acceptorless dehydrogenation of amines and oxygen transfer of DMSO. This system demonstrates excellent catalytic activity and selectivity, converting various primary amines and even diamines into the corresponding amides with yields ranging from good to quantitative (>99%). The remarkable catalytic performance of this binuclear ruthenium complex is attributed to a unique chelating model that allows efficient oxygen transfer from DMSO via a six-membered ring transition state.

Summary: MW-assisted catalytic degradation of organic pollutants using Cu-loaded biochar catalysts showed high efficiency in the mineralization of refractory and high-concentration oxytetracycline. Reactive oxidizing species, which were barely detectable in a conventional heating system, played a crucial role in achieving the high efficiency in MW-assisted oxidation systems. The interactions between CuBC and MW were revealed by correlating the physiochemical characteristics to the MW absorption ability. These proposed catalytic systems have significant implications for the development of a high-throughput and low-carbon wastewater treatment technology.

Summary: This study investigated the interfacial transition zone (ITZ) in biochar-augmented carbon-negative cementitious materials using various analysis techniques. The results revealed significant changes in hydration degree and porosity at the edge of biochar. The integration of biochar and cement was mainly achieved through the formation of Ca-rich hydration products. In terms of mechanical behavior, biochar exhibited viscous-elastic deformation while hardened cement displayed plastic-elastic properties. The distinct differences in deformation contributed to the higher compressive strength of biochar-cement composites.

Summary: Selective and highly efficient extraction technologies are crucial for the recovery of critical metals from spent lithium-ion battery (LIB) cathode materials. The tailored deep eutectic solvent (DES) choline chloride-formic acid (ChCl-FA) demonstrated high selectivity and efficiency in extracting critical metals from mixed cathode materials under mild conditions. Mechanochemical reactions further enhanced the leaching performance of critical metals and inhibited the leaching of nontarget elements, thus promoting selectivity and efficiency.

Summary: The aim of this study was to characterize extensively drug-resistant Pseudomonas aeruginosa from a patient with diarrhea. Antimicrobial susceptibility testing revealed that P. aeruginosa had a wide spectrum of resistance to antibiotics. Genomic analysis identified 76 genes associated with antimicrobial resistance, xenobiotic degradation, and the type three secretion system. This is the first report on diarrhea associated with P. aeruginosa, suggesting dysbiosis due to antibiotic exposure and the potential role of T3SS in in vivo toxicity of the pathogen.

Summary: A PtNi/HT catalyst was prepared and used for glucose hydrogenation, achieving a high conversion rate of 95.7% and selectivity of 90.1% to polyols at 393 K in water. The catalyst demonstrated stability and recyclability for glucose conversion. Lower reaction temperatures favored hexitol production, while higher temperatures facilitated the generation of polyols with less carbon. The Pt delta--Ni delta+ pair on PtNi/HT played a crucial role in H2 activation and adsorption during glucose hydrogenation. The basic support of PtNi/HT efficiently catalyzed glucose isomerization and retro-aldol reaction in the aqueous phase.

Summary: Density functional theory calculations revealed the mechanism and stereoselectivity of chiral guanidine/copper(I) salt-catalyzed stereoselective three-component reaction. The rate-determining step for the noncatalytic cascade reaction was the denitrogenation to generate ketenimine species. Chiral guanidine-amide promoted deprotonation of phenylacetylene and coordinated with copper to activate TsN3 for the Cu(I)-ketenimine species.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.
