NEAR UV LIGHT AND CATARACTS*

Ordered nanowire array blue/near-UV light emitting diodes.

ZnO-based light emitting diodes (LEDs) have been considered as a potential candidate for the next generation of blue/ near-UV light sources, [ 1 ] due to a direct wide bandgap energy of 3.37 eV, a large exciton binding energy of 60 meV at room temperature, and several other manufacturing advantages of ZnO. [ 2 ] While the pursuit of stable and reproducible p-ZnO is still undergoing, [ 3,4 ] het...

Formic Acid Decomposition Using Synthesized Ag/TiO2 Nanocomposite in Ethanol-Water Media Under Illumination of Near UV Light

The effect of ethanol-water media on the synthesis of Ag/TiO2 nanocomposite was investigated with 0.05, 0.1 and 0.5 (wt.%) of Ag content. Ethanol was used as hole-scavenger enhancing the photodecomposition of Ag+ ions under illumination of near-UV light. The nanocomposites were further calcined to 300˚C and 400˚C under controlled atmosphere. The synthesized nanocomposites were tested for photoc...

Removal of Azithromycin from aqueous solution using UV- light alone and UV plus Persulfate (UV/Na2S2O8) processes

Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...
