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 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.

The surface properties of some steel alloys can be adjusted through the introduction of specific elements via diffusion. An example of such a process is nitriding, where nitrogen is diffused into the ...

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, ...

A new study finds poor quality of available foods, increased intake of calories from foods high in trans-fatty acids, and environments that do not foster physical activity, all prevalent in ...
