Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

open access: yesAdvanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Determination of Water-Soluble Solvent in Liquid Detergents by Steam-Carrier Gas Chromatography

open access: yesJournal of Japan Oil Chemists' Society, 1981
A gas chromatography, using water-vapor as a carrier gas, was investigated for the determination of water-soluble solvents in liquid detergents. These solvents were separated and determined on porous polymer beads columns, Porapak Q or Tenax GC, and quantitatively recovered from standard detergent in the range of useful formulation.
