Type of Lasers Used in This Study, cage-like structure whose twelve atoms occupy the vertices of an icosahedron. Strong covalent bonds link icosahedra to one another. As a result, boron carbides are very stiff, hard solids whose melting temperatures exceed 2600K. Boron carbides have long been used in applications such as lightweight

The Bipolar Quantum: Wave-Particle Dualityattice there is not enough space to hold Sr atoms between the Ge atoms, for example. The presence of these “guests” induces a change in the Ge clathrate to a more open structure: the clathrate structure. These types of “open structured” compounds have unique properties that are of interest for therm

Yasunori Nomura,Bill Poirier,John Terning of thermoelectrics has resulted in several interesting structures. A common feature of many of these novel thermoelectrics is a relatively open atomic configuration that offers numerous possibilities to modify the material with the aim of maximizing its thermoelectric efficiency. Among these novel

R134a was developed as a replacement for freon (R12), because freon destroys the protective ozone layer in the stratosphere. Unfortunately, R134a could contribute to global warming.. This has prompted an intense search for new refrigeration technologie
