Poly(ethylene glycol) (PEG), a kind of "green" medium, was used to extract artemisinin from the Chinese herb Artemisia annua L. to replace the traditional volatile and explosive solvents like petroleum ether, diethyl ether, etc. PEGs, with different molecular weights, show excellent ability for artemisinin extraction, and the extraction efficiency ...

This study investigated the evolution of physicochemical indexes and taste parameters of Gouqi fermented wine during storage process, and further test if different aging treatments could affect the evolution pattern of these parameters. Results showed that bottle-aged wine exhibited an increase in the sourness, bitterness, and astringency compared ...

The grains that form the basis of most commercial chicken diets are rich in cellulose, an unbranched beta-1,4-linked D-glucopyranose polymer, used as a structural molecule in plants. Although it is a predominant polysaccharide in cereal hulls, it is considered an inert non-fermentable fiber. The aim of the current study was to analyze the effect of...
Hydrogels are interesting as wound dressing for burn wounds to maintain a moist environment. Especially gelatin and alginate based wound dressings show strong potential. Both polymers are modified by introducing photocrosslinkable functionalities and combined to hydrogel films (gel-MA/alg-MA). In one protocol gel-MA films are incubated in alg-MA so...
A novel type of heteropolyacids, CTAB-CsH3PMo11VO40 (CTA-CsPAV), was developed by a method of emulsion synthesis using cetyltrimethyl ammonium bromide (CTAB) as the structure promoter, which was applied as a catalyst in the oxidation of methacrolein (MAL) to methacrylic acid (MM) with fixed-bed reactor. The structure and property of CTA-CsPAV were ...
Separation of cellulose I (TM) material from biomass with high efficiency by using ionic liquid (IL) is still challenging. In this work, three low-cost polyhydric protic ammonium-salt ILs (about $1000/t) based on sulphonethane anion were synthesized via one-step protonation reaction and firstly applied in the pretreatment of corn straw. After study...
