Lattice‐Strained Cu2O‐Ni/NiO Heterostructure Enables Selective Electrocatalytic C–C Coupling of Alcohols to Cinnamaldehyde in Aqueous Medium

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.

2D measurements of turbulence & mixing driven by internal waves impinging on a slope

, 2015
Fluxes in stratified water bodies such as lakes and oceans are often controlled by turbulence and mixing at sloping boundaries. One mechanism of boundary mixing is the reflection of internal waves from slopes; when the angle that the internal wave ray ...

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 ...

Tidal Conversion by Supercritical Topography

, 2009
Calculations are presented of the rate of energy conversion of the barotropic tide into internal gravity waves above topography on the ocean floor. The ocean is treated as infinitely deep, and the topography consists of periodic obstructions; a Green ...
