Advanced Materials, EarlyView.Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)
Advanced Materials, EarlyView.Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
