The surface dynamics of amorphous and semicrystalline polymer films have been measured using helium atom scattering. Time-of-flight data were collected to resolve the elastic and inelastic scattering ...

Discovery of the amorphous surface layer Between temperatures of –152 °C and –93 °C, the new simulations revealed for the first time that an 'amorphous' layer forms on the surface of ice —where it is ...

Researchers explain the dissolution behavior of silica glasses manufactured by different processes, a natural biologically produced silica and a synthetic, dispersed or colloidal silica. Their ...

Blacksburg, Va. – From toothpaste to technology, noncrystalline or amorphous silica is an active ingredient in a myriad of products that we use in our daily lives. As a minor, but essential component ...

These two common methods are used to prepare electron transport specimens for a range of materials including metals, semiconductors and ceramics. FIB is feasible in cases when there is a need for ...

A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That's because, even though hydrogen is abundant, it must be derived from another ...

New research by scientists with the US Department of Energy’s Argonne National Laboratory lends insight that could be used to design new materials for making renewable fuels and storing energy. The ...
