Nanophase metals usually are many times harder but more brittle than regular metals. nanophase copper is a superhard material; nanophase aluminum; nanophase iron is iron with a grain size in the nanometer range. Nanocrystalline iron has a tensile strength of around 6 GPA, twice that of the best maraging steels.
Nanophase ceramic. Nanophase ceramics are ceramics that are nanophase materials (that is, materials that have grain sizes under 100 nanometers). [1] [2] They have the potential for superplastic deformation. [1] Because of the small grain size and added grain boundaries properties such as ductility, hardness, and reactivity see drastic changes ...
The Center for Nanophase Materials Sciences is the first of the five Nanoscale Science Research Centers sponsored by the United States Department of Energy. It is located in Oak Ridge, Tennessee and is a collaborative research facility for the synthesis, characterization, theory/ modeling/ simulation , and design of nanoscale materials.
Karren L. More is an American materials scientist who is the Director of the Center for Nanophase Materials Sciences at the Oak Ridge National Laboratory. Her research considers advanced electron microscopy as a probe to understand the structure and chemistry of emerging materials. More is a Fellow of the American Ceramic Society and Microscopy ...
Yogi Rock, analyzed by the Sojourner rover (July 4, 1997). The surface color of the planet Mars appears reddish from a distance because of rusty atmospheric dust. [1] From close up, it looks more of a butterscotch, [1] and other common surface colors include golden, brown, tan, and greenish, depending on minerals.
A phase-change material ( PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. The phase transition may also be between non-classical states of matter, such as ...
