Carbon Energy, EarlyView.A dual‐functional evaporator based on CAU‐23/graphene hybrid is acquired through a modular design strategy. Owing to superior broadband light absorption, optimal wettability, and porous architecture that synergistically integrates nanoconfined ionic channels with photothermal conversion, it exhibits a high evaporation rate of 2.71 kg m−2 h−1 with the ...

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system
The Canadian Journal of Chemical Engineering, EarlyView.Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

Journal of Raman Spectroscopy, EarlyView.We apply a sharp silicon tip, typically used for atomic force microscopy (AFM), as a nanoscale probe, and collect frequency‐shifted photons resulting from Raman scattering within the sharp tip. This approach allows us to map local electromagnetic fields in various plasmonic structures and study field “hotspots” with nanometer spatial resolution ...
