Ca[Ti(HPO)(PO)]·HO, Ca[Ti(HO)(HPO)]·HO, and Ti(HPO): Solid-State Oxidation via Proton-Coupled Electron Transfer.

Titanium phosphorus oxides (TiPOs) are promising energy-conversion materials, but most are of tetravalent titanium (Ti), with the trivalent TiPOs less explored because of instability and obstacles in synthesis. In this study, we used a simple synthetic strategy and prepared three new TiPOs with different phosphorus oxoanions: the phosphate CaTi(HPO)(PO)·HO (), the phosphite CaTi(HO)(HPO)·HO (), and the hypophosphite Ti(HPO) (). Each possesses different structures in one, two, and three dimensions, yet they are related to one another because of their infinite chains.

A titanium(iii) phosphite exhibits polymorph-distinct redox activity involving proton-coupled electron transfer.

A novel titanium(iii) phosphite with intriguing polymorphism and solid-state proton-coupled electron transfer (PCET) oxidation is presented. The polymorphs show structure-dependent PCET reactivity, interpretable by proton distribution in channels. Combined with subsequent photoreduction, the redox cycle initiated with Ti can produce H and transform organics.

Deltamethrin increases the fat accumulation in 3T3-L1 adipocytes and Caenorhabditis elegans.

Research has shown that permethrin, a Type-I pyrethroid, increases triglyceride (fat) accumulation in adipocytes. Little is known, however, about any similar effect of deltamethrin, a Type-II pyrethroid, which produces a distinct syndrome of poisoning in mammals compared with permethrin. This study was therefore aimed to explore the role of deltamethrin on fat accumulation in 3T3-L1 adipocytes and Caenorhabditis elegans.
