Supported metal clusters are widely used in catalysis for many important reactions. To
understand the catalytic properties, in situ/operando characterization techniques, such as X …

Synchrotron X-rays are widely used for material characterizations. However, they can also
ionize atoms and molecules to damage and manipulate probed materials. We report here an …

The surface tension of liquid Agsingle bondCu eutectic alloy has been measured in a wide
range of oxygen partial pressures using two different methods: the constrained drop method …

Surface-enhanced Raman scattering (SERS) substrates with low cost, high sensitivity and
good reproducibility are still challenging in practical application. Herein, we propose a facile …

Nitrogen (N2) is an essential element for life, but kinetically stable N2 in the atmosphere
needs to be reduced to biologically available forms as a nutrient for organisms. Abiotic …

Binary and mixed oxides incorporating transition metal cations host a broad range of
scientifically compelling and technologically significant optical, electronic, and magnetic …
