Consumer electronic devices are made from materials that we have been using for more than 60 years, mainly silicon, germanium and copper. Why have semiconductor electronics become increasingly fast over this time?
Imagine if phones never got hot no matter how many apps were running. Picture a future where supercomputers use less energy, electric cars charge faster, and life-saving medical devices stay cooler and last longer.
Superconductivity—the ability of some materials to conduct electricity with no energy loss—holds immense promise for new technologies from lossless power grids to advanced quantum devices.
The melting of crystals is the process by which an increase in temperature induces the disruption of the ordered crystalline lattice, leading to the disordered structure and highly fluctuating dynamic behavior of liquids. ...
Magnesium is a common chemical element, an alkaline earth metal, which is highly chemically reactive and is very light (even lighter than aluminum). Magnesium is abundant in plants and minerals and plays a role in human physiology ...
Superconductivity is a quantum phenomenon, observed in some materials, that entails the ability to conduct electricity with no resistance below a critical temperature. Over the past few years, physicists and material scientists ...
Complex materials such as organic semiconductors or the microporous metal-organic frameworks known as MOFs are already being used for numerous applications such as OLED displays, solar cells, gas storage and water extraction. ...
Imagine a world where your phone stays cool no matter how long you use it, and it's also equipped with tiny sensors that can identify dangerous chemicals or pollutants with unparalleled sensitivity and precision.
Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange ...
Recently, a research group led by Prof. Wang Zhenyang and Zhang Shudong from the Hefei Institutes of Â鶹ÒùÔºical Science of the Chinese Academy of Sciences, developed a new type of ceramic fiber aerogel, SiC@SiOâ‚‚, featuring ...
