One-Step Synthesis of Cationic Hydrogel for Efficient Dye Adsorption and Its Second Use for Emulsified Oil Separation

Abstract: The removal of toxic dyes and insoluble oil from wastewater is a hot topic in both academic and industrial fields. Herein, we report a cationic absorbent poly(epichlorohydrin)–ethylenediamine hydrogel (PEE-Gel) via a simple one-step copolymerization and it can be successfully used for the removal of toxic dyes and insoluble oil from wastewater. The adsorption toward anionic dyes shows high efficiency and high selectivity at a wide pH range (from 2 to 12). The adsorption capacity at low equilibrium concentration (10 mg L–1) is as high as 1411.4 mg g–1 which is very close to the maximum adsorption capacity (1540.19 mg g–1). The adsorption of dye molecules onto PEE-Gel is very steady and can be difficult to be regenerated. The PEE-Gel with full dye adsorption (PEE-Gel-Dye) shows superoleophobicity under water, and PEE-Gel-Dye can be reused to separate toluene-in-water emulsion with high efficiency and durability. These results suggest that PEE-Gel is a promising and competitive candidate for water purification.

Bacteriophage Polysaccharide Depolymerases and Biomedical Applications

Abstract: Polysaccharide depolymerase, a polysaccharide hydrolase encoded by bacteriophages (or 'phages'), can specifically degrade the macromolecule carbohydrates of the host bacterial envelope. This enzyme assists the bacteriophage in adsorbing, invading, and disintegrating the host bacteria. Polysaccharide depolymerase activity continues even within biofilms. This effectiveness means phages are promising candidates for novel antibiotic scaffolds. A comprehensive compendium of bacteriophage polysaccharide depolymerases has been compiled, together with their potential biomedical applications, such as novel antibiotics, adjuvants for antibiotics, bacterial biofilm disruptants, and diagnostic kits.

Novel High-Efficiency Casein-Based P–N-Containing Flame Retardants with Multiple Reactive Groups for Cotton Fabrics

Abstract: Novel, high-efficiency, and halogen-free flame retardants with reactive groups, casein-based FRs, were synthesized based on a casein hydrolysis solution for cotton fabrics. After treated by the cas...

Intergeneration social support affects the subjective well-being of the elderly: Mediator roles of self-esteem and loneliness

Abstract: The mental health of the elderly is an important issue in the area of health psychology. This study investigated the effect of intergeneration social support on the subjective well-being of 429 elderly participants. Results suggested that intergeneration social support, self-esteem, and loneliness were significantly correlated to subjective well-being. Structural equation modeling indicated that self-esteem and loneliness partially mediated the effect of intergeneration social support on subjective well-being. These findings provided insights into the effect of intergeneration social support on the subjective well-being of the elderly.
