DOI: 10.1016/j.apsusc.2018.06.128

Abstract: Abstract Although high energy TiO2 nanocrystals (HE-TiO2-NCs) with exposed (0 0 1) facets shows superior photoreactivity in oxidation of organic pollutants, they are suffering from the problem of hard to be collected in recycling use. In this… read more here.

DOI: 10.1016/j.jes.2018.02.025

Abstract: Methylmercury (MeHg) bioaccumulation is a growing concern in ecosystems worldwide. The absorption of solar radiation by dissolved organic matter (DOM) and other photoreactive ligands can convert MeHg into less toxic forms of mercury through photodemethylation.… read more here.

DOI: 10.1016/j.toxlet.2019.09.016

Abstract: This study involved an attempt to establish a new photosafety screening system for dermally-applied chemicals consisting of a reactive oxygen species (ROS) assay and an in vitro skin permeation test. The ROS assay was undertaken… read more here.

DOI: 10.1021/acs.est.3c01157

Abstract: Predicting the formation of photochemically produced reactive intermediates (PPRI) during the irradiation of dissolved organic matter (DOM) has remained challenging given the complex nature of this material and differences in PPRI formation mechanisms. We investigate… read more here.

DOI: 10.3390/molecules27010189

Abstract: Polyphenols are a large family of natural compounds widely used in cosmetic products due to their antioxidant and anti-inflammatory beneficial properties and their ability to prevent UV radiation-induced oxidative stress. Since these compounds present chromophores… read more here.
