Positive correlation between human exposure to organophosphate esters and gastrointestinal cancer in patients from Wuhan, China.

As kinds of endocrine disruptors, organophosphate esters (OPEs) pollution in the environment had received increasing attention recently. Food and water intake were two important exposure pathways for OPEs. However, the studies about the potential association between OPEs and gastrointestinal cancer were limited.

Rational Design of 3D Hierarchical Ternary SnO/TiO/BiVO Arrays Photoanode toward Efficient Photoelectrochemical Performance.

BiVO as a promising semiconductor absorber is widely investigated as photoanode in photoelectrochemical water splitting. Herein, the rational design of 3D hierarchical ternary SnO/TiO/BiVO arrays is reported as photoanode for photoelectrochemical application, in which the SnO hierarchically hollow microspheres core/nanosheets shell arrays act as conductive skeletons, while the sandwiched TiO and surface BiVO are working as hole blocking layer and light absorber, respectively. Arising to the hierarchically ordered structure and synergistic effect between each component in the composite, the ternary SnO/TiO/BiVO photoanode enables high light harvesting efficiency as well as enhanced charge transport and separation efficiency, yielding a maximum photocurrent density of ≈5.
