Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

The action of monochromatic ultaviolet light on proteins

Biochimica et Biophysica Acta, 1957
Abstract The ultraviolet inactivation spectra are reported for dry trypsin at 300° K and 90° J, gramicidin, RNA-ase in acid and alkali, and aldolase. Trypsin and RNA-ase, which have relatively large amounts of cystine, have action spectra which differ markedly from their absorption spectra. Their action spectra show a large component which is similar

Degree of paraxiality for monochromatic light beams

Optics Letters, 2008
We introduce the degree of paraxiality as a paraxiality measure of a monochromatic light beam. Computation of this parameter is possible once the plane-wave spectrum of the field being analyzed is given for a starting source plane. On the basis of this definition, quantitative comparisons of the paraxiality of different types of fields are possible. In

BRIGHTNESS SCALES FOR MONOCHROMATIC LIGHT

Scandinavian Journal of Psychology, 1960
By means of amethod of ratio estimation, scale values were obtained for the subjective brightness of various physical intensities of monochromatic light of various wave lengths. In a second experiment the scale was constructed by a method of magnitude estimation.
