Minimal levels of ultraviolet light enhance the toxicity of TiO2 nanoparticles to two representative organisms of aquatic systems
(Springer, 2014-07-25)
A number of studies have been published concerning the potential ecotoxicological risks of titanium dioxide nanoparticles (nano-TiO2), but the results still remain inconclusive. The characteristics of the diverse types of ...
Evaluation of ex vivo melanogenic response to UVB, UVA, and visible light in facial melasma and unaffected adjacent skin
(Elsevier B.V., 2020-11-01)
Background: The independent rote of solar radiation in the differential melanogenesis between melasma and adjacent skin is unknown. Objectives: To assess the melanogenic responses of skin with facial melasma and of the ...
Fast removal of Candida parapsilosis from hemodialysis dialysate using ultraviolet or visible light at nanoporous W/WO3 electrodes
(2019-08-01)
The quality of the water used in a hemodialysis process is critical, and several cases of contamination by C. parapsilosis have been reported in the literature. In addition, it is causing many deaths. The present work ...
Hair color changes and protein damage caused by ultraviolet radiation
(Elsevier Science SaLausanneSuíça, 2004)
Fish exposure to nano-TiO2 under different experimental conditions: Methodological aspects for nanoecotoxicology investigations
(2013-10-01)
The ecotoxicology of nano-TiO2 has been extensively studied in recent years; however, few toxicological investigations have considered the photocatalytic properties of the substance, which can increase its toxicity to ...
Visible-Light-Induced Photocatalytic and Antibacterial Activity of TiO2 Codoped with Nitrogen and Bismuth: New Perspectives to Control Implant-Biofilm-Related Diseases
(2019-05-22)
Biofilm-associated diseases are one of the main causes of implant failure. Currently, the development of implant surface treatment goes beyond the osseointegration process and focuses on the creation of surfaces with ...
Doping of polyaniline and derivatives induced by X-ray radiation
(1997-01-01)
Thin films of chemically synthesized polyaniline and poly(o-methoxyaniline) were exposed to ionizing X-ray radiation and characterized by radiation induced conductivity measurements, ultraviolet-visible spectroscopy, ...
