A team of researchers at the University of California San Diego have fabricated the first optically-controlled, semiconductor-free microelectronic device.
A new study suggests that scientists can eventually help to develop materials that resist breaking, or crack in a predictable manner.
Scientists at Penn State believe that the discovery of atomic chains in a two-dimensional crystal could help them to find a way to handle the direction of materials properties in both two- and three-dimensional crystals. This could have implications in next-generation electronics, optoelectronics and sensing applications.
A team of researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have demonstrated that permanent magnets developed by additive manufacturing are capable of outperforming bonded magnets made using standard methods while conserving critical materials.
In the world of big data, there are limitations on storing large volumes of information. Typical home-computer hard disk drives use up a lot of power and are limited to a few terabytes per drive. Optical storage media such as Blu-ray and DVD, are energy efficient and inexpensive, however storage densities are very low because of the optical diffraction limit and planar nature of the discs. However, scientists have made progress on creating a 3D diamond chip capable of storing vastly more data compared to existing technologies.
The magnetic properties of materials have inspired technologies from traditional recording tape to advanced hard drives over the years. Scientists are continually pushing to develop new applications from magnetic behavior.
Glass fibers are used in numerous applications - from connecting people to the internet to enabling keyhole surgery by supplying light via medical devices such as endoscopes. Although today's fiber optics is versatile, scientists globally are eager to broaden their capabilities by incorporating semiconductor core materials to the glass fibers.
Bonds between two sulfur atoms that link long molecules together are indispensable in rubber and proteins. Unexpected complex processes are generated when pulling from outside on the disulphide bonds.
Next to silicon, germanium (Ge) is the most widely used semiconductor material in the world. While it is great at conducting electricity, Ge is inefficient at turning light into electricity or electricity into light, and this factor restricts its use in other applications.
The Second Law of Thermodynamics, which states that entropy always increases, is the most inviolable law for over a century and a half of physics. Chaos reigns supreme in this universe. Recently researchers at the U.S. Department of Energy's (DOE's) Argonne National Laboratory claimed that they have potentially found a small loophole in this well-known Second Law.
