Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Quantitative Determination of Zirconium and Hafnium Based on the in situ Pyrolysis of Their Tetramandelates

Analytical Sciences, 1989
Two methods are proposed for the quantitative determination of zirconium and hafnium. One is based on weighing their precipitates as the tetramandelates, followed by analyses of the plateau regions observed in their thermogravimetric curves (method A); another is followed by a gravimetric determination of the ignition residue of tetramandelate in a ...

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
