Hierarchical Co3O4@CdIn2S4 p–n heterojunction photocatalysts have been constructed by an in situ surface growth method for CO2 reduction with visible light.

Branch-like ZnS–DETA/CdS hierarchical heterostructures are synthesized as an efficient photocatalyst for visible light CO2 reduction in a tandem system.

There is a strong correlation between ocular itching and Demodex infestation and between symptomatic resolution and reduction of Demodex counts by daily lid massage with 5% TTOO.
