in this study the application of zno nanoparticles to uv photocatalytic degradation of nonionic surfactanttriton x-100 in aqueous media was investigated. the affecting factors on the photodegradation such as tritonx-100 initial concentration, nanocatalyst weight, ph, temperature and other parameters were studied anddescribed in details. the degradation rate was found to be strongly influenced b...

UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...
