Wafer‐Scale Atomically‐Thin Gold: Transferable Platform for Flexible Optoelectronics, Thermal Management and Bio‐Interfaces

Advanced Science, EarlyView.
Combining template stripping with a graphene‐inspired transfer yields continuous, transferable gold films at 6‐inch wafer scale with thicknesses approaching the atomic limit. The atomically smooth, near‐bulk‐quality films offer above 86% transmittance and sub‐20 Ω/square sheet resistance, serving as a universal platform for flexible optoelectronics ...

Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts

Advanced Science, EarlyView.
Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

Vanadium Cation Exchange‐Driven Reconstruction of MOF‐Derived Cobalt Hydroxide Electrodes for Electrocatalysis and Energy Storage

Advanced Science, EarlyView.
A room‐temperature vanadium cation exchange strategy is developed to achieve simultaneous structural reconstruction and electronic/defect modulation of ZIF‐67 on nickel foam. The resulting mesoporous V20–Co(OH)2 electrode exhibits superior OER activity with low overpotentials and enhanced lattice oxygen participation.
