Poor cycling performance for many high voltage lithium ion batteries (LIB) has been attributed to damage of the anode solid electrolyte interphase (SEI) resulting from crossover reactions. Transition-metal proposed as a primary source SEI and capacity loss, especially high-voltage spinel cathodes. However, deposition transition metals on may not be degradation. This investigation focuses oxidat...

Ethylene is an important signaling molecule in plants that triggers the growth of leaves, flowers, and fruits. One enzymes involved biosynthesis ethylene ethylene-forming enzyme (EFE), which usual nonheme iron biodegrades ?-ketoglutarate into three CO2 molecules ethylene. As detailed mechanism EFE remains controversial particularly function co-substrate l-arginine, we decided to pursue a densit...

A set of PEGylated derivatives of oleanolic and maslinic acids has been semi-synthesised, attaching ethylene glycol, diethylene glycol, triethylene glycol or tetraethylene glycol to the C-28 carboxyl group of these natural triterpenes and some derivatives. Another set of PEGylated derivatives has been semi-synthesised by connecting the same four ethylene glycols to the hydroxyl groups of the A ...

introduction: nowadays, due to mechanization of life, consumers need of food which they spent little time for preparation, so fresh cut industry is growing rapidly in the world. these products had strong growth since 1940, and in 2013, most sales of fresh cut fruit related to apples, against 21.8 percent. minimal processing operations include grading, washing, sorting, slicing, chopping and the...

For a group of nonionic surfactants with polar head groups synthesized by the copolymerization ethylene oxide and carbon dioxide, potential for their application in foam flotation microplastic particles was investigated. Their performance compared to conventional that correlated adsorption behavior at water–air surface through maximum-bubble-pressure technique. The carbonate content surfactant ...

Next generation, multifunctional separators can enhance energy storage, power, and safety performance of lithium ion batteries but must be simple to fabricate incorporate with existing roll-to-roll manufacturing. This study presents a strategy facilely prepare these using UV-initiated polymerization-induced phase separation (PIPS), wherein microporous polymer are fabricated directly from consti...

This paper presents the results of a study random copolyethersulfone sulfides based on 4,4-dichlorodiphenylsulfone, 1,1-dichloro-2,2-di(4-hydroxyphenyl)ethylene, and sodium sulfide. The synthesis with different ratios polyethersulfone polyphenylenesulfone sulfide units was carried out by high-temperature polycondensation reaction nucleophilic substitution in N,N-dimethylacetamide medium using p...
