Electrical and computer engineering researchers demystify the role of negative capacitance in modern MOSFETs. • Email to a friend • Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. • Email to a friend • Scientists find a unique knotted structure - one that repeats itself throughout nature - in a ferroelectric nanoparticle, a material with promising applications in microelectronics and computing. • Email to a friend • Algorithms, gold and holographic references boost biomolecule diffraction. • Email to a friend • Particle-scale phenomenon akin to the swerving of a curveball could allow selective separation of suspended nanomaterials. • Email to a friend • Researchers developed a new technique to locally modify the properties of a metamagnetic material. The method consists in applying local pressure to the surface of the material using nanometric needles and allows a much more easy and local modification than current methods. • Email to a friend • New research demonstrates the integration of synthetic biology with electronic circuitry through engineered population dynamics that regulate the accumulation of charged metabolites. The resulting sensor devices can detect changes in bacterial population in response to the presence of chemicals, light or pH. Connecting bacterial gene expression to electrodes is an appealing approach to interface genetic circuits with microelectronics for multiple applications. In this work, researchers engineered bacterial circuits capable of controlling the conductivity of the media via cell growth and death. Therefore, the electronic output is controlled by a killing gene. • Email to a friend • Reseaerchers create millimeter-size chips with unique color patterns that cannot be forged. • Email to a friend • |
