Power/Performance Bits: Sept. 3


Nylon capacitor Researchers at the Max Planck Institute for Polymer Research, Johannes Gutenberg University of Mainz, and Lodz University of Technology developed a way to fabricate ferroelectric nylon thin-film capacitors. Nylons consist of a long chain of polymers and, along with use in textiles, exhibit ferroelectric properties. However, electronic applications have been limited as there ... » read more

Power/Performance Bits: July 15


Liquefied gas electrolyte Researchers at UC San Diego, U.S. Army Research Laboratory, and South 8 Technologies developed an electrolyte that could enable the replacement of the graphite anode in lithium-ion batteries with lithium-metal. Such a change would increase energy density 50% at the cell level, making for lighter batteries with more capacity. However, lithium-metal anodes are not compa... » read more

Week in Review: IoT, Security, Auto


Products/Services Arteris IP reports that Bitmain licensed the Arteris Ncore Cache Coherent Interconnect intellectual property for use in its next-generation Sophon Tensor Processing Unit system-on-a-chip devices for the scalable hardware acceleration of artificial intelligence and machine learning algorithms. “Our choice of interconnect IP became more important as we continued to increase t... » read more

System Bits: June 25


Supercomputers around the world At last week’s International Supercomputing Conference in Frankfurt, Germany, the 53rd biannual list of the Top500 of the most powerful computing systems in the world was released. Broken out by countries of installation, China has 219 of the world’s 500 fastest supercomputers, compared with 116 in the United States. Ranking by percent of list flops, the ... » read more

System Bits: June 4


Thin films for quantum computing Researchers at Los Alamos National Laboratory report their development of two-dimensional tungsten/selenium thin films that can control the emission of single photons, potentially useful in quantum technologies. “Efficiently controlling certain thin-film materials so they emit single photons at precise locations—what’s known as deterministic quantum em... » read more

Power/Performance Bits: June 4


Flexible high-temp dielectric Researchers at Rice University, Georgia Institute of Technology, and Cornell University developed a new high-temperature dielectric nanocomposite for flexible electronics, energy storage, and electric devices that combines one-dimensional polymer nanofibers and two-dimensional boron nitride nanosheets. The polymer nanofibers act as a structural reinforcement, w... » read more

Power/Performance Bits: May 28


Archival storage Researchers at Harvard University and Northwestern University propose a method of long-lived archival data storage using low-weight molecules. DNA has been explored as a method of archival storage, but the researchers argue that it is inadequate, as the DNA macromolecule is large and requires skilled, repetitive labor to encode and read. Instead, the researchers turned... » read more

Week in Review: IoT, Security, Auto


Internet of Things Verizon Communications launched its nationwide narrowband Internet of Things network, saying it covers more than 92% of the U.S. population. “There is a whole universe of smart solutions needing scalable and affordable connections,” Jeffrey Dietel, senior vice president of business marketing and products, said in a statement. “By launching our NB-IoT network, Verizon i... » read more

The Limits Of Energy Harvesting


Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

End-To-End Cell–Pack–System Solution: Rechargeable Lithium-Ion Battery


Industry has become more interested in developing optimal energy storage systems as a result of increasing gasoline prices and environmental concerns. A major application for energy storage use is hybrid electric vehicles (HEVs) and electric vehicles (EVs). The rechargeable energy storage system is a key design issue, as it dominates overall vehicle performance. The system as a whole must deliv... » read more
