Impact of Ayurvedic drug Tinospora cordifolia in hyperlipidemia induced dysbiosis
Gut microbiota broadly impacts human health, but urinary microbial metabolites remain largely undefined. The concentration of microbial metabolites can be directly correlated with microbial populations in the human gut to define disease states. Tinospora cordifolia (Willd.) Miers ex Hook. F. & Thoms is being used for ages in the Indian ayurvedic system of medicine and…

Gas sensing of partially oxidized Ti3C2Tx MXene in argon atmosphere
Multilayer accordion like Ti3C2Tx MXene is prepared by selective etching of Al layer from Ti3AlC2 MAX phase. For better gas sensing responses, a minimal amount of TiO2 decoration is being carried out by annealing the Ti3C2Tx MXene in an argon atmosphere at 550 °C for 6 h. The X-ray diffraction pattern shows successful removal of…
