Influence of water immersion and ultraviolet weathering on mechanical and viscoelastic properties of polyphenylene sulfide-carbon fiber composites
(Sage Publications Ltd, 2015-03-01)
In order to investigate the combined action of temperature, humidity, and ultraviolet (UV) radiation, polyphenylene sulfide (PPS)-carbon fiber composite specimens were exposed to environmental degradation through two ...
Doping of polyaniline and derivatives induced by X-ray radiation
(1997-01-01)

Solar ultraviolet A radiation and nonmelanoma skin cancer in Arica, Chile
(Elsevier, 2020)
In this work, we present the maximum daily values of solar ultraviolet A radiation (UV-A) as a function of time. The results indicated that such values reached a maximum of 93.9 W/m(2) in 2010 and a minimum of 16.5 W/m(2) ...
