GOOI FETs The next-generation power semiconductor market is heating up. Two wide-bandgap technologies—gallium nitride (GaN) on silicon devices and silicon carbide (SiC) MOSFETs—are ramping up in the power semi market. In addition, the industry is also exploring various futuristic technologies, such as bulk vertical GaN, diamond FETs and others. Purdue University has demonstrated another... » read more

Atom interferometers The Massachusetts Institute of Technology (MIT) has devised one of the world’s most accurate atom interferometers. Interferometry is a common measurement technique. Basically, the technology looks at electromagnetic waves. The waves are superimposed to extract information. One interferometry technology type, called an atom interferometer, utilizes the waves of ato... » read more

3D printed military drones The U.S. Army Research Laboratory has begun testing 3D printed drones for use in on-demand military missions. The technology, called the On-Demand Small Unmanned Aircraft System (ODSUAS), enables a soldier to input the mission requirements in software. Then, a 3D printer devises the optimal configuration for an unmanned aerial vehicle. And it’s printed and deliv... » read more

Coffee ring effect In physics, the “coffee ring effect" has been the subject of study for years. This phenomenon is a simple concept. A liquid or droplet hits a surface and dries. The particles in the droplet are suspended. And ultimately, it leaves a ring-like pattern. The phenomenon is named for the formation of a ring-like deposit when coffee or other liquid resides on a surface. ... » read more

3D printed wind instruments Autodesk Research and Dartmouth have developed a 3D printing technology that enables novel musical wind instruments in the form of animals, doughnuts and other shapes. With a 3D printer, researchers devised 16 free-form wind instruments in various shapes, such as a star, bunny, snowman, dragon, horse, pig, cat and sheep. There is even a way to make a doughnut in... » read more

Phonon lasers A European consortium recently kicked off a new project that will develop a practical phonon laser. The European consortium, called PHENOMEN, will be coordinated by the Catalan Institute of Nanoscience and Nanotechnology (ICN2). Most chips perform functions using an electrical charge (electrons) or by light (photons). In comparison, a phonon “is a quantum of energy or a q... » read more

The National High Magnetic Field Laboratory (MagLab) has broken an unofficial record for the world’s most powerful hybrid magnet. The 33-ton system, called the series connected hybrid (SCH) magnet, has reached its full field strength of 36 tesla. The SCH is more than 40% stronger than the previous world-record hybrid magnet. Tesla, or T, is the measurement of magnetic field strength. A ref... » read more

Supersonic kinetic spraying Low-cost flexible electronics could enable a new class of products, such as roll-up displays, wearable electronics, flexible solar cells and electronic skin. There is a major barrier to enable these technologies, however. The problem is to make flexible transparent conducting films that are scalable and economical. The University of Illinois at Chicago and Kor... » read more

Materials database The Department of Energy’s Lawrence Berkeley National Laboratory has published a study that quantifies the thermodynamic scale of metastability of some 29,902 materials. To quantify the materials, researchers used Berkeley Lab’s Materials Project, a large and open database of known and predicted materials. The open and Web-based database has calculated the properties ... » read more

Tiny magnifying glass The University of Cambridge has devised what researchers claim is the world’s smallest magnifying glass. More specifically, researchers developed a tiny optical cavity, dubbed a pico-cavity. The pico-cavity consists of self-assembled, biphenyl-4-thiol molecules. These materials are sandwiched between gold nanostructures the size of a single atom. With the pico-cav... » read more
