Hydrogen has gained renewed and growing interest around the world in recent decades as a high-quality renewable energy carrier, owing primarily to advances fuel cells well environmental concerns. Steam reforming of fossil-based resources is currently main route H2 production. The downside this process, however, generation massive amounts greenhouse gases including CO2 byproduct which turn must be captured fully exploit potential H2. Membrane separation technology seen significant growth,...

Electrocatalytic glucose oxidation can produce high value chemicals, but selectivity needs to be improved. Here we elucidate the role of Pt state on activity and electrocatalytic with a new analytical approach, using high-pressure liquid chromatography anion exchange chromatography. It was found that type oxidation, i.e. dehydrogenation primary secondary alcohol groups or oxygen transfer aldehyde groups, strongly depends state. Pt0 has 7-fold higher for reactions than reactions, while PtOx...

Here we present the preparation of a novel positively charged covalent organic polymer (COP) based nanofiltration membrane. The porous COP selective layer grows on top polybenzimidazole (PBI) support from coupling reaction 1,3,5-tris(bromomethyl)benzene and 4,4′−dipyridyl in alkaline conditions. Chemical morphological analyses confirm formation thin (less than 50 nm), which is also evidenced by its high water permeance salt retentions. Moreover, it shown that membranes can form hydrogen...

Electrocatalytic hydrogen peroxide (H2O2) production, over Ni based catalysts, through 2 electron oxygen reduction (ORR) is an environmentally friendly alternative compared to the traditional anthraquinone process. To understand catalytic performance in more detail, geometrical particle size effect of nickel nanoparticles for this ORR reaction investigated. The results show a linear relationship between both turnover frequency (TOF) and Faradaic efficiency (FE) with number edge corner atoms...

Water recycling is one of the most sustainable solutions to growing water scarcity challenges. However, wastewaters usually contain organic pollutants and often are at extreme pH, which complicates treatment these streams with conventional membranes. In this work, we report synthesis a robust membrane material that can withstand prolonged exposure pH (of 1 or 13 for 2 months). Polyamine thin film composite (TFC) membranes prepared in situ by interfacial polymerization between...

Chicken feathers are major byproducts of the livestock processing industry with high potential in feed sector. In this study, we present a new approach using Fourier transform infrared (FTIR) spectroscopy to detect structural changes feather keratin and its availability for enzymatic hydrolysis (AEH) induced by thermal pressure (TPH) process. Compared time-consuming vitro measurement techniques, proposed method provides rapid information about during TPH which enables quick adaptation...

Genetic programming (GP) is an orderly method based on natural evolution rules for getting computers to regularly solve a problem. In the present study, GP presented as novel approach modeling gas sparging assisted microfiltration of oil-in-water emulsion process. The effects flow rate (QG), oil concentration (Coil), transmembrane pressure (TMP), and liquid (QL) permeate flux rejection were studied models developed predict membrane performance. Coil TMP showed significant both rejection. An...

This work simulates the production of methyl crotonate from various industrial wastewaters. In upstream process, wastewater is fermented into volatile fatty acids which are then converted polyhydroxyalkanoates (PHA) by means mixed microbial cultures. downstream, PHA undergoes a series thermolysis and esterification reactions to produce crotonate. The origin was found have great influence on composition with effluent candy bar factory producing high polyhydroxybutyrate/polyhydroxyvalerate...
