Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.

Summary: Promoted ethylene glycol yield from cellulose hydrogenolysis is achieved using nickel-tungsten doped carbon catalysts. Mechanistic investigations reveal that increasing tungsten loading leads to an improved bronsted acid content, which facilitates cellulose hydrolysis and suppresses glucose isomerization. Additionally, high tungsten loading promotes oxygen vacancies and retro aldol condensation of glucose, resulting in increased ethylene glycol yield.

Summary: The efficacy of bioaugmentation with nondomesticated mixed microbial consortia was evaluated in mitigating ammonia-induced microbial inhibition. The results showed that the bioaugmented culture significantly improved methane production under high ammonia concentrations by regulating the symbiotic relationships between different microbial species. The type and dose of the consortium were identified as crucial factors determining the effectiveness of bioaugmentation.

Summary: In this study, an intelligent solvent-responsive surface molecularly imprinted membrane (SR-SMIMs) was developed for the separation and recovery of Psoralen (PSO). The membrane demonstrated remarkable adsorption capacity in methanol and efficient desorption. The recognition mechanism of SR-SMIMs was identified to be a synergistic effect of hydrogen bonding, 7C-7C stacking, and Van der Waals forces. The method showed promising potential for specific separation of target compounds from complex natural plant extracts.

Summary: The effective utilization of lignin is crucial for sustainable biomass conversion and the development of renewable resources. This study focuses on the catalytic oxidative transformation of lignin and explores its structural features and their impact on product diversity. The content of beta-O-4 linkages in lignin and the presence of S-type structural units are found to be important factors that influence the yield and efficiency of the conversion process. However, the complex nature of lignin presents challenges for its efficient depolymerization and utilization. A comprehensive understanding of lignin's structure is crucial for advancing its effective utilization and the development of renewable resources.

Summary: Reducing carbon footprint and greenhouse gas emissions is a global goal. This study developed a technology for wastewater treatment in small-decentralised plants, focusing on bioelectrochemical systems (BES) that utilize bacteria to remove pollutants while generating power. Experiments showed that the BES system outperformed conventional trickling filters in terms of organic matter and phosphate reduction. A novel dual-BES system with improved cathode positioning demonstrated improved wastewater treatment and generated electrical output.

Summary: Previous studies on compost dissolved organic matter (DOM) have mainly focused on its composition and humification, neglecting the importance of DOM bioavailability in understanding compost fertility. This study investigated the bioavailability of DOM in thermophilic compost (TC) and vermicompost (VC), and linked it to its molecular composition. It was found that the bioavailability of VC DOM (36% BDOC) was generally higher than that of TC (22% BDOC) due to higher content of tannin-like substances. Furthermore, the differences in bioavailability between VC and TC increased as the C/N ratio decreased in the composting materials.

Summary: Linseed or flaxseed is an ancient industrial crop used for oil and fiber production. The bud fly is a serious pest that affects the production of linseed. In this study, a large collection of linseed germplasm accessions were screened for bud fly infestation, and a subset of resistant accessions was identified. Two accessions, G22 and G23, showed high resistance and stability against bud fly infestation. These accessions can be potential donors for breeding linseed varieties with broad-spectrum resistance against bud fly.
