Summary: Phenoxyethanol (EPH) was used to create a biphasic solvent system for lignin extraction from lignocellulosic biomass. The concentration of EPH was studied to determine the pre-treatment condition for lignin fractionation. The lignin from rice straw was then fractionated using a 70% aqueous EPH solvent system, resulting in the regeneration of lignin with varying purities using different precipitants. The compositional and structural characteristics of the regenerated lignin were also analyzed.

Summary: This study investigated the adsorption performance of methylene blue using Ca(OH)2-modified rice straw biochar derived from agricultural and forestry wastes. The modified biochar exhibited excellent adsorption capacity for methylene blue, with a Langmuir fitting adsorption capacity 12.5 times higher than that of pristine rice straw biochar. The Ca(OH)2 modification increased the polarity, Ca content, and oxygen-containing functional groups of the biochar, enhancing the chemical adsorption of methylene blue.

Summary: This experiment investigated the removal efficiency and mechanisms of potassium permanganate modified biochar (MBC) on arsenic and cadmium. The results showed that MBC had significantly higher sorption capacities for arsenic and cadmium in a coexisting solution compared to a single solution. The formation of ternary complexes and electrostatic adsorption were the main mechanisms for MBC to remove cadmium and arsenic. MBC proved to be an effective material for simultaneous removal of arsenic and cadmium from contaminated water.

Summary: This paper proposes an automated Ejection Fraction estimation system from 2D echocardiography images using deep semantic segmentation neural networks. Two parallel pipelines of deep semantic segmentation neural network models have been proposed for efficient left ventricle segmentation, and three different neural networks, UNet, ResUNet, and Deep ResUNet, have been implemented. The most accurate model achieved high Dice scores for left ventricle segmentation in both systolic and diastolic states. The proposed system can remove the eyeball estimation practice and reduce inter-observer variability.

Summary: The production of economic green hydrogen fuel is in high demand. In this study, hydrogen generation by water radiolysis of a hexane-water system on ZrO2 surface was investigated at different temperatures. The radiation-catalytic decomposition of hexane-water increased at high temperatures and resulted in an increase in hydrogen production. At a temperature of 673 K, a chain mode conversion of the key products of hexane-water led to molecular hydrogen. The maximum yield of hydrogen achieved was 188.5 molecule/100 eV with the n-ZrO2 + C6H14(ads)-water (0.003 g: 0.0051 g: 0.0015 g) system at 673 K.

Summary: In this study, graphene-based nanofluids were synthesized and their viscosities were determined. The molecular interactions of graphene nanoparticles were theoretically analyzed to understand the mechanisms affecting the viscosity of nanofluids. An analytical function describing the dependence of the relative viscosity on the concentration of graphene nanoparticles was obtained based on experimental results. It was found that the viscosity of the nanofluid was influenced by the structure of the graphene sheets, and the self-assembly of the nanoparticles played a crucial role in the viscosity changes.
