We report on the synthesis, structure, and physicochemical characterization of the first three examples of neutral palladium‐oxo clusters (POCs). The 16‐palladium(II)‐oxo cluster [Pd16O24(OH)8((CH3)2As)8] (Pd16) comprises a cyclic palladium‐o

Calcination of hybrid organic–inorganic Titanium-Ethylene Glycol (Ti-EG) thin films yield non-stoichiometric titania with deep valence band maximum (VBM) with down-shift of up to 450 meV relative to stoichiometric TiO2. We previously reported the e
