FeS2 nanocrystals with the diameter of more than several dozen nanometers exhibit well-defined optical extinction peaks in a near-infrared region. These peaks, which are not exhibited from bulk FeS2, have been ascribed to the localized surface plasmo

For the future use of hydrogen storage alloys for ammonia synthesis, nitrogen absorption behaviors of ZrVFe, ZrVFe (Ti) and ZrVFe (Ti-Al), where the elements in parentheses were added or substituted, were volumetrically investigated by successively a

We describe efficient visible- and near-infrared (vis/NIR) light-driven photocatalytic properties of hybrids of Cu2O and plasmonic Cu arrays. The Cu2O/Cu arrays were prepared simply by allowing a Cu half-shell array to stand in an oxygen atmosphere f
