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 ...

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.

Researchers at Fudan University are developing a reconstruction algorithm that enables quantitative bone imaging using ultrasonic computed tomography. (Courtesy: Dean Ta) Osteoporosis is a bone ...

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.

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, ...

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 ...

Pressure tube deformation is an important aging issue in operating heavy water reactors (HWRs) and the R&D community continues to develop improved predictive models for in-reactor deformation. To ...

Applied to apple and pear fruit, the model achieved very high accuracy, outperforming previous 2D approaches and traditional algorithms. The 3D structure of plant tissues underlies vital metabolic ...
