Summary: This study presents a method for designing wood bio-adhesives using sewage sludge extracts (SSE). The SSE was obtained from sewage sludge using deep eutectic solvents, and then processed with glycerol triglycidyl ether (GTE) to disrupt protein structure. The bio-adhesive produced had sufficient wet shear strength and improved quality through Maillard reaction and dehydration. This method offers a more environmentally friendly and economically efficient approach for utilizing sewage sludge and developing bio-adhesives for the wood industry.

Summary: The sulfur transformation behavior during co-hydrothermal carbonization of sludge and food waste model compounds was investigated. The addition of starch and xylan significantly increased the sulfur retention ratio in hydrochar. These model compounds can react with different sulfur forms to form various organic sulfur compounds and transform into hydrochar through polymerization reactions with hydrolyzed intermediates. Cellulose enhanced the formation of sulfone-S in hydrochar, while the hydrolysate of palmitic acid facilitated the polymerization of sulfur from aqueous to hydrochar.

Summary: This study investigated the transformation of mercury species, especially methylmercury, in sludge composting. The findings showed that there was no significant change in the overall content of mercury and methylmercury before and after composting, but a certain percentage of both were lost. Anaerobic bacteria were identified as the main methylators of mercury in the initial stages of composting. The study also revealed the presence of genes related to mercury transformation in various microbial genomes.

Summary: The global environmental problems caused by sewage sludge generated from population growth and urbanization have caught the attention of scientists worldwide. This study explores the potential of using sewage sludge from wastewater treatment plants to improve and stabilize collapsible soils. Different soil-sludge mixtures with varying percentages of sludge were analyzed through physical, chemical, and edometric experiments. The findings suggest that adding sludge to the soil reduces void index, enhances particle packaging, and decreases soil collapsibility at specific dry apparent weights, making it a promising method for improving collapsible soils.

Summary: Pulsed laser ablation in liquid is an efficient and environmentally friendly method for synthesizing pure and stable nanoparticles. However, achieving complete control over the physical characteristics of nanoparticles is challenging due to the short interaction time between the laser pulses and the target. Process parameters, liquid environment, and external fields significantly affect the morphology and structure of nanoparticles.

Summary: The effects of different solvents (2,2,2-Trifluoroethanol, 1-propanol, Ethanol and Acetonitrile) on the performance of D149 dye-sensitized ZnO-based solar cells were investigated using a quantum mechanical model. The incorporation of solvents with low transition energies was found to enhance current densities and improve the efficiency of the solar cells. Among the tested solvents, 2,2,2-Trifluoroethanol showed the highest efficiency of 1.662%. Ethanol inclusion had a slightly lower efficiency due to a lower fill-factor, but higher current density. The decrease in open circuit voltage was compensated by the obtained gain in J(sc), leading to maximum efficiency for solar energy conversion.

Summary: The electronic structures of four tin-based 0D hybrid perovskites were investigated using the DFT method, and the effect of Van der Waals interaction on the electronic structure was explained. It was found that incorporating organic cations with the appropriate structure into hybrid perovskite crystals can enhance the efficiency of hybrid perovskite-based devices by preventing ion migration. The study of optical properties showed that Van der Waals interactions have a slight effect on the energy level but do not alter the shape of the absorption curves.
