A novel nanofiltration membrane, whose active layer consists of 98.6 wt% a thermocatalytic perovskite with composition Sr0.85Ce0.15FeO3-δ (CSF), 1.0 graphene oxide (GO), and 0.4 humic acid-like (HAL) crosslinker, was deposited over commercial flat-sheet polyethersulfone support good reproducibility by simple 1-step coating procedure. The synergistic coupling CSF the crosslinked GO resulted in a...

Separation of monosaccharides and monovalent salts is important in the biorefinery food industry. Nanofiltration (NF) technology promising for this purpose but its poor selectivity still needs to be addressed. In work, separation by NF improved regulating surface charge pore size distribution polyamide membranes. The carboxyl groups on membrane are selectively activated N-(3-Dimethylaminopropyl...

Due to their stable chemical properties and complex structures, dyes are difficult be removed from water. Herein, a ZIF-67/SA@PVDF (ZSA3@PVDF) mixed matrix membrane has been fabricated by incorporating silicon aerogel (SA) zeolitic imidazolate framework material 67 (ZIF-67) nanoparticles in polyvinylidene fluoride (PVDF) for the removal degradation of The influence SA ZIF-67 on morphology struc...

Methods: In this study, cleaning process was studied and analyzed with special reference to cleaning tools. A group of 13 professional cleaners participated in this study. While they performed their normal tasks, their oxygen consumption, heart rate, rating of perceived exertion and postural data were obtained. The perceived exertion during cleaning task using the ‘‘redesigned cleaning tool’’ w...

Platform chemicals such as medium-chain carboxylic acids (MCCAs) can be produced from organic waste streams via chain elongation in anaerobic mixed-culture bioreactors. A product recovery system is needed to collect MCCAs the bioreactor effluent. Membrane-based liquid–liquid extraction, most commonly used approach, requires suspended solids removal effluent avoid membrane fouling. An dynamic (A...
