ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study achieved the selective oxidation C–C coupling of PhCH2OH with EtOH to form cinnamaldehyde (CAL) on a designed Cu2O‐Ni/NiO heterojunction catalyst. By employing a salt precipitation strategy to balance the pH and cation concentration, an 86% conversion rate of PhCH2OH and a 67% high selectivity for CAL were realized.

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

Numerical Analysis of Two-Phase Multi-Material Flow Field in Hydrothermal Jet Drilling
Shiyou jixie, 2019 Hydrothermal jet drilling is a new type of drilling method suitable for deep hard formation. It generates high-temperature and high-pressure jet to break rock through supercritical oxidation reaction in downhole reactor.

European Journal of Organic Chemistry, EarlyView.The Pd‐catalyzed decarboxylative asymmetric protonation (DAP) has been developed for sterically hindered tetrahydro‐4H‐pyran‐4‐one derived α‐aryl‐β‐keto esters. A substrate scope of nine examples of DAP showed that substrates containing a di‐ortho methoxy substitution pattern on the aryl ring gave rise to the highest enantioselectivities of up to 85 ...

ELECTROPHORESIS, EarlyView.This study examined 21 new ferrocene and ruthenocene derivatives, including those with planar and central chirality. Their stereochemical behavior was examined using UV‐detected normal‐phase liquid chromatography. Under fixed conditions, eight polysaccharide‐based chiral stationary phases were tested using n‐heptane combined with either 2‐propanol or ...
