Engineering hierarchical FeS/TiO nanotubes on Ti mesh as a tailorable flow-through catalyst belt for all-day-active degradation of organic pollutants and pathogens.

The increasing organic and microbiological pollutions in fresh water caused by human activities and industrial development have become a global concern nowadays. In this study, three-dimensional (3D) hierarchical FeS/TiO structures with nanotube geometries were grown on a Ti mesh (M-TNTAs-FeS). Benefitting from the abundant available reactive sites on the open 3D micro/nanoporous structures, excellent photocatalytic activity of FeS/TiO heterostructure in solar light, and satisfactory Fenton activity of FeS, the obtained M-TNTAs-FeS exhibits outstanding performance as an all-day-active catalyst.

An anion exchange reaction: an effective approach to prepare alloyed Co-Fe bimetallic disulfide for improving the electrocatalytic activity.

A mild anion exchange approach is proposed for the synthesis of alloyed Co-Fe bimetallic disulfide. Abundant structural disorders and tunable compositions are effectively induced by the anion exchange process. The alloyed Co-Fe bimetallic disulfide exhibits a low overpotential of 205 mV to reach a current density of 100 mA cm-2 in an acidic electrolyte, which is significantly improved compared to the performance of individual disulfide.

Curcumin improves bone microarchitecture and enhances mineral density in APP/PS1 transgenic mice.

Alzheimer's disease and osteoporosis are often observed to co-occur in clinical practice. The present study aimed to evaluate the bone microarchitecture and bone mineral density (BMD) of the proximal tibia in APP/PS1 transgenic mice by micro-computed tomography (micro-CT), and to search for evidence that curcumin can be used to reduce bone mineral losses and treat osteoporosis after senile dementia in these transgenic mice.
