The Heihe River Basin (HRB) is a typical arid inland river basin in northwestern China. From the 1960s to 1990s, downstream flow HRB declined as result of large, artificial changes distribution water and land lack effective resource management. Consequently, ecosystems lower reaches substantially deteriorated. To restore these degraded ecosystems, Ecological Water Diversion Project (EWDP) was initiated by Chinese government 2000. project led agricultural ecological middle basin. In this...

The strategy for converting glucose directly to new types of furanic compounds under mild conditions is based on retro-aldol condensation followed by aldol C2 and C4 fragments with acetylacetone.
Mycotoxins co-contamination in soybean poses great risks to human health, however, due their diverse structures, it is difficult simultaneously extract and detect these multi-mycotoxins. By incorporating modification of hydrophilic carboxyl groups with the hydrophobic properties covalent organic frameworks, a stable cubic carboxyl-functionalized magnetic amide-linked framework were fabricated, characterized utilized as adsorbents for solid phase extraction (MSPE) eleven frequently detected...
Abstract Furans with side‐chains at C(2) of various lengths terminating in diazomethyl keto groups are shown to undergo Rh 2 (OAc) 4 ‐catalyzed furan unravelling the production 2‐cyclopentenone, 2‐cyclohexenone, and 2‐cycloheptenone each whose olefinic C(β) is attached an acrylaldehyde unit. Interposition a cyclohexane or methylaminomethylene moiety between diazoketo functions leads formation hydroindenone pyrrolone, respectively. Replacement diazomethylketo terminus by α‐diazoethylketo...

Abstract Lactic acid is a versatile and potential building block for generating biodegradable plastics polylactic acid, as well in chemical pharmaceuticals industry. Nevertheless, the achievement of lactic production large quantities remains an enormous challenge. Herein, series yttrium‐modified composite metal oxide catalysts were synthesized starting from renewable biomass cellulose. Interestingly, Y 2 O 3 /Al showed outstanding chemoselectivity towards due to its predominant Lewis sites...
Using two monomers of 4,4″-diamino-p-terphenyl and 1,3,5-triformylphloroglucinol, a co-precipitation structured magnetic covalent organic framework adsorbent was fabricated. After that, high efficient vortex-assisted solid-phase extraction method developed prior to gas chromatography-tandem mass spectrometry analysis for the determination phthalate esters in milk samples. The fabricated facilely fabricated, fully characterized, exhibited efficiency, which can be attributed its larger pore...
