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.

Magnetic Resonance in Chemistry, EarlyView.We present CEEN: a Python‐based control software for coupled electrochemistry, EPR, and NMR for redox flow battery (RFB) and electrosynthesis research. We demonstrate CEEN through practical applications relevant to aqueous organic and inorganic RFB and electrochemical synthesis research. The same setup can be readily used to study any (electrochemical)
