Functional biochar and catalytic sustainable biosynthesis of PHA derived from waste activated sludge.

Advancing circular wastewater management, this study developed an innovative solution for waste activated sludge (WAS) utilisation by constructing a system in whichWAS wasconverted to biochar and feedback catalysed biosynthesis of Polyhydroxyalkanoates (PHA). After PHA extraction, residual sludge was pyrolysed into biochar, which acted as a catalyst to further enhance PHA production by the self-fermentation conversion of WAS. Biochar significantly improved electron transfer during anaerobic digestion (by 61.

Functional Characterization of Involved in Regulating Pollen Tube Growth from Passion Fruit.

Passion fruit (), mainly distributed in tropical and subtropical regions, is popular for its unique flavor and health benefits. The actin cytoskeleton plays a crucial role in plant growth and development, and villin is a key regulator of actin dynamics. However, the mechanism underlying the actin filament regulation of reproductive development in passion fruit remains poorly understood.

Micro-graphite particles accelerate denitrification in biological treatment systems.

Accelerated denitrification is an essential problem in the biological treatment of nitrogenous wastewater. In this study, we report that denitrification is accelerated by micro-graphite particles (MGPs). The denitrification rate was increased by 83.

Design, synthesis, and antitumor activity of novel acylate of 6-OH at 1- O-acetylbritannilactone.

N-(α-Alkyloxime-3-phenylpropionyl) proline was designed and synthesized as an acylating agent to modify the 6-OH of 1-O-acetylbritannilactone. Eight intermediates and eight target compounds were obtained. The structures of sixteen novel compounds were characterized by (1)HNMR, IR and HRMS.

Enhanced reduction of C-N multiple bonds using sodium borohydride and an amorphous nickel catalyst.

Amorphous nickel powder (Ni(0)) was utilised as a catalyst under mild, aqueous, basic conditions for enhancing the sodium borohydride-mediated reduction of C-N multiple bonds such as oximes, imines, hydrazones and nitriles to produce the corresponding amines in good to excellent yields.
