Based on density functional theory calculations, this study analyzed the gas-sensing performance of TiCT (T=O, F, OH) monolayers modified with precious metal atoms (Ag and Au) for HCHO and CH gas molecules. Firstly, stable structures of Ag- and Au-single-atom doped TiCT (T=O, F, OH) surfaces were constructed and then HCHO and CH gas molecules were set to approach the modified structures at different initial positions. The most stable adsorption structure was selected for further analysis of the adsorption energy, adsorption distance, charge transfer, charge deformation density, total density of states, and partial density of states.

Type 2 diabetes mellitus (T2DM), a metabolic disorder, has the hallmarks of persistent hyperglycemia, insulin resistance, and dyslipidemia. Protein-tyrosine phosphatase 1B (PTP1B) was found to be overexpressed in many tissues in the case of T2DM and involved in the negative regulation of insulin signaling. So, PTP1B inhibition can act as a therapeutic target for T2DM.
