Scientists from Lawrence Livermore have discovered a way to generate linear chains of carbon atoms from laser-melted graphite. The material, known as carbyne, has many properties, including the capability of adjusting the amount of electrical current traveling through a circuit. “Its linear shape gives it unique electrical properties that are sensitive to stretching and … [Read more...]
New Type of Electric Glue Developed
Recently, a research group at Nanyang Technological University (NTU) has developed a type of glue that hardens after a low voltage is applied to it. They nicknamed the new adhesive “Voltaglue.” “We had to find a way to make glue which cures (hardens) when we want it to without being affected by environmental conditions, so electricity was the best approach for us. The hardness … [Read more...]
New Technique in Photonic ICs and Optical Computing
A new technique could be a big step toward photonic ICs and optical computing, according to researchers at ITMO University in St. Petersburg, Russia. The technique uses a single silicon nanoparticle as an optical transistor. “In research published in the journal Nano Letters, the Russian scientists turned away from using nanoparticles to control the absorption of light and … [Read more...]
2D Hybrid Perovskites Grown
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have grown atomically thin 2D sheets of organic-inorganic hybrid perovskites. These 2D hybrid perovskites are ionic materials that have unique properties, making them possible successors to silicon. “The ultrathin sheets are of high quality, large in area, and square-shaped. They also … [Read more...]
Phosphorene Has Unique Qualities
In 2014, researchers conducted experiments where they exfoliated black phosphorus, or phosphorene, into very thin films of about 10 to 20 atoms thick. Phosphorene, has an inherent bandgap, or energy band in which no electron states can exist, that graphene lacks. According to Philip Feng, an assistant professor of electrical engineering and computer science at Case Western … [Read more...]
