Effect of UVA irradiance on photocatalytic and UVA inactivation of Bacillus cereus spores

Journal of Photochemistry and Photobiology B: Biology, 2009
The current study is the first to delineate the contribution of photocatalysis to inactivation of Bacillus cereus endospores on dry surfaces over a broad range (0-153W/m(2)) of UVA irradiance. Inactivation of spores at low UVA irradiance (30W/m(2)) was primarily due to photocatalysis, whereas at higher UVA irradiance inactivation was primarily due to ...

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

UVA ERYTHEMA IN SKIN: IS IT A SUNBURN?

Journal of Investigative Dermatology, 1977
Specimens obtained from human skin following the induction of erythema responses with long ultraviolet (UVA) and with middle ultraviolet (UVB) radiation alone were compared histologically to determine whether the effects of these two portions of the electromagnetic spectrum were the same.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural
