A professor has a lesson in one of his mechanical engineering courses on how brittle materials like calcium carbonate behave under stress. In it, he takes a piece of chalk composed of the compound and ...

In a world of 8 billion people, there's one thing that makes each of us unique: our fingerprints. A variety of genetic and environmental factors create tiny variations in the skin's ridges and whorls, ...

Lithium and sodium metal anodes play a crucial role in the further development of high-performance solid-state batteries. In order to favorably influence the electrochemical properties of these highly ...

For thousands of years, humans have combined metals to collectively harness properties found in individual components, producing such practical materials as bronze, brass and, more recently, steel.

The common engineering ceramic materials can be identified as Aluminium Oxide (Alumina), Silicon Carbide, Silicon Nitride, Sialon and Zirconia. These materials are classified as “Engineering” or ...

The properties of steel can be improved in terms of fatigue, weldability, hardness, wear and corrosion resistance, ductility, and tensile strength by either alloy addition or heat treatment processes.
