Physicists at the University of Illinois at Chicago have identified the “quantum glue” that binds electrons together to evoke superconductivity in a crucial step towards the creation of high-speed energy transport methods that conduct electricity without current loss. The new research, published online in the Proceedings of the National Academy of Sciences, is a collaboration … [Read more...]
Electrically Conductive, Sodium Silicate Coating for EMI/RFI Shielding
Master Bond, Inc. has released MB600G, an aqueous-based, sodium silicate system with graphite filler well suited for EMI/RFI shielding applications. Graphite-filled materials are widely used for shielding and static dissipation applications because of the balance of shielding effectiveness and cost. Shielding effectiveness is most often measured by attenuation. It is defined … [Read more...]
Valley Current Properties of New Transistor Material Could Outdo Silicon
Researchers at Cornell University have identified and tested a semiconducting compound that could outdo silicon in terms of performance, and could signal the emergence of a new kind of transistor material in electronics. The findings, compiled in the paper, “The Valley Hall Effect in MoS2 Transistors,” published recently in Science, revealed promising conductive capabilities … [Read more...]
Researchers Predict Electrical Resistivity of Metals Under Extreme Pressures
A study recently published in the Proceedings of the National Academy of Sciences (PNAS), headed by scientists at Rensselaer Polytechnic Institute (RPI), has demonstrated how subjecting metals to intense pressures could lower their electrical resistance, which could potentially lead to increased speed and performance in many technologies. Strain engineering, or the … [Read more...]
Medical-Grade Heat-Shrink Tubing for Cable Shielding
Methode Electronics, Inc. has released new medical grade shrinkMate™ heat-shrink tubing, which provides easy-to-apply shielding at the cable-to-connector joint, a common point of leakage. Made of clear medical grade polyester, the lightweight tubing shrinks when heat is applied to firm a conductive seal around an object, providing EMI, RFI and ESD shielding without the use of … [Read more...]
Risk of ESD-Sensitive Devices in Proximity to ANSI/ESD STM2.1-Compliant Garments by Field-Induced Model Discharge
Bob Vermillion CPP/Felow Certified, ESD Engineer-INARTE RMV Technology Group, LLC A NASA Industry Partner During ESD assessments, it is not uncommon to see personnel wearing wool, silk, cotton, polyester blends and static control overalls (ESD Garments). Some ESD garment types consist of an embedded conductive grid network (Figure 1) in combination with cotton or polyester … [Read more...]
Graphene May Boost RF Absorption
New research from scientists in the UK examines graphene’s ability to absorb electromagnetic radiation with the creation of optically transparent broadband absorbers operating in the millimeter frequency range. Since graphene's isolation by University of Manchester scientists in 2004, research efforts worldwide have focused on harnessing its unique electrical, optical, … [Read more...]
Better Magnetic Spin Wave Control for Electronic Devices
Researchers have developed a method for creating and controlling quick-moving waves in magnetic fields they say could improve communication and information processing in computer chips and other electronic devices. Created by scientists in the Department of Physics at New York University, the new technique relies on “spin waves,” waves that move in magnetic materials similar … [Read more...]
