Photobenzidine rearrangement: Photodecomposition of N.N'-dimethylhydrazoaromatics and 1,4-dialkyl-1,4-diphenyl-2-tetrazenes
… an alcoholic solution of hydrazobenzene with a mercury lamp. Later, traces of rearrangement product, ortho- and para-semidines, were detected in the reaction fixture by paper chromatography. Recently, Shine and co-workers found that N,N'-dimethyl- -aminodiphenylamine can be isolated as the major …

Photochemical Protection of Riboflavin and Tetrapyrroles with Light Scattering Technology
… A photochemical reactor, equipped with a 350W mercury lamp, provided full spectrum light or narrow bandwidth wavelength exposure, using filters allowing transmission at 25 nm wavebands at maximum peak height at 450, 550, or 650 nm. Riboflavin concentration was measured by HPLC over 8 hours of …

Photoconductivity studies of the ferrocyanide ion under high pressure
… apparatus and a steady-state high-pressure mercury lamp. The first-order photocurrent rise-time could be related to the relative quantum efficiency of the photoaquation process, while the dark decay of the photocurrent yielded a relative value of the bimolecular rate-constant for the reverse …

MOVPE growth and characterization of Al(Ga)N and InAlN/AlGaN quantum wells for UV LED applications
… bulky, expensive and environmentally harmful mercury lamp as new UV light sources. For application to UV LEDs, reducing the threading dislocation density (TDD) in AlN epilayers on sapphire substrates is a key parameter for achieving high-efficiency AlGaNbased UV emitters. In Chapter 4, after …
