Investigating the Breakdown Mechanism in High-Speed Electronic Devices

A team of researchers use in-situ transmission electron microscopy (TEM) to record the dynamic evolution of structural and electrical interfacial properties of zirconium dioxide films on aluminum oxide and indium gallium arsenide (InGaAs) substrates. This investigation paves the way towards faster, more efficient high-speed electronic devices.

High-Performance Heterogeneous Catalyst with High Water Dispersibility

High-Performance Heterogeneous Catalyst with High Water Dispersibility

Researchers from the Suzhou Key Laboratory of Green Chemical Engineering, Soochow University, and from the State Key Laboratory of Molecular Engineering of Polymers, Fudan University, develop a one-step, solvent-free method to prepare a high-performance heterogeneous catalyst. The cobalt-based catalyst is highly dispersible in water and is effective for the tandem sodium borohydride dehydrogenation and nitrobenzene hydrogenation at room temperature.
