Invisible objects have potential military, research, and technology applications, including hiding people, weapons, and troop movements. Other systems developed over the last few decades have all had weaknesses: they were hard to make,…

In preparation for APEC 2019, GaN Systems has unveiled the industry's highest current  650 V GaN E-HEMTs with the addition of the 150 A, 650 V and the 80 A, 650 V line of GaN power transistors. In particular, the 150 A, 650 V transistor is…

Researchers at the Massachusetts Institute of Technology (MIT) have discovered a possible new use for spider silk. In addition to being one of the strongest materials for its weight, the resilient fibers respond to changes in humidity. This…

Shape memory polymers (SMP) have major implications for healthcare, and Syracuse University engineers have created a new kind of SMP that could be useful for healing. SMPs are soft, rubbery, "smart" materials that can change shape in…

Unraveling the mystery of superconductivity at high temperatures, specifically in copper oxide materials, remains one of the most puzzling challenges in modern solid-state physics. An international research team of engineers and scientists…

Hokkaido University researchers have developed a strategy to fabricate materials that become stronger in response to mechanical stress - mimicking skeletal muscle growth. This discovery could pave the way for long-lasting materials that can…

Piezoelectric materials inhabit everything from our cell phones to musical greeting cards. Now, researchers from Virginia Tech's College of Engineering have developed methods to 3D print these materials, and as a result can be…

Rather than building up plastic filaments layer by layer, a new approach to 3D printing lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3D printing processes. While 3D printing could change the game for…
