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.

Metallizing of Silicon Nitride Ceramics
Journal of the Ceramic Association, Japan, 1986 It was found that a metallized layer can be formed on Si3N4 ceramics using the paste containing Li2MoO4 and TiO2. X-ray diffraction pattern and SEM observations revealed that the metallized layer consisted of Mo, TiN, Y2O3⋅2SiO2, etc., and that the thickness was around 7μm.

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...
