Skin cancer incidence in Croatia is steadily increasing in spite of public and governmental permanently measurements. It is clear that will soon become a major public health problem. The primary cause of skin cancer is believed to be a long exposure to solar ultraviolet (UV) radiation. The future designers of UV protective materials should be able to block totally the ultraviolet radiation. The...

We propose an algorithm to retrieve the global features of the spectral dependence of the ultraviolet (UV) irradiance from integrated, broadband UV measurements performed with a set of photodiodes with different UV filters. This fit, when applied to ground-based measurements and compared with the incident Solar spectral irradiance on the top of the atmosphere, may be used to extract the spectra...

Herein, reduced graphene-oxide-supported ZrO2 and Y2O3 (rGO-ZrO2 rGO-Y2O3) nanocomposites were synthesized by hydrothermal method used as the catalysts for photodegradation of picric acid. The structural morphological properties samples characterized using an X-ray diffractometer (XRD), scanning electron microscope (SEM) with energy dispersive absorption spectroscopy (EDAX), UV-Vis spectrophoto...
