Effect of Ga doping on the catalytic performance of Zn-ZSM-5 for CO2-assisted oxidative dehydrogenation of C2H6

Journal of CO2 Utilization
Using a low silica-to-alumina ratio NaZSM-5 zeolite as the support, a bimetallic modified catalyst, GaxZnZ5, was prepared through ion-exchange method for CO2-mediated oxidative dehydrogenation of C2H6 (CO2-ODH).

Assessing TiO2/Chitosan‐Based Hydrogels for Water Remediation: Sunlight‐Driven Degradation of Antibiotics in Water

Advanced Materials Interfaces, EarlyView.
Chitosan–TiO2 composite hydrogels combine adsorption of organic pollutants with photocatalysis, allowing to remove 85% of a broadly diffused antibiotic (sulfamethoxazole) under direct sunlight irradiation, opening great promises for point‐of‐use, outdoor applications.

Insight Into the Origins of N2O Byproduct on Confinement Structure TiO2/MnSm Catalyst Through Sulfation Pre‐Treatment for Low‐Temperature NH3‐SCR Reaction

EcoEnergy
Mn‐based catalysts are the most promising catalysts for low‐temperature NH3‐SCR, but improving N2 selectivity still faces great challenges. Herein, the tubular structure TiO2–SO42−/MnSm assembled from nanosheets was developed, which exhibited superior NO

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
