2D/2D/2D Metallic 1T Phase WS2/TiO2/Ti3C2Tx MXene Ternary Composite for Synergistically Enhanced N2 Electroreduction

EcoEnergy, EarlyView.
TiO2 nanosheets were in situ grown on Ti3C2Tx MXene, and then 1T phase WS2 was distributed on TiO2/Ti3C2Tx MXene to form 1T‐WS2/TiO2/Ti3C2Tx MXene, which exhibits a prominent NH3 yield of 46.27 μg h−1 mg−1cat. at −0.8 V versus RHE and a superior FE of 69.26% at −0.65 V versus RHE.

RSM–ANFIS‐Based Process Optimization of Thermo‐Sonication of Amla Juice: Effect on Enzyme Inactivation, Physico‐Chemical, Phytochemical, Sensory, and Microbiological Quality

Food Chemistry International, EarlyView.
Thermo‐sonication parameters were optimized to maximize PPO inactivation while maintaining overall juice quality. ANFIS demonstrated superior predictive accuracy with higher R2 and lower RMSE compared to RSM. Further, the quality assessment of treated juice highlighted the potential of thermo‐sonication as a sustainable alternative to conventional ...
