Integrating Memristors For Neuromorphic Computing


Much of the current research on neuromorphic computing focuses on the use of non-volatile memory arrays as a compute-in-memory component for artificial neural networks (ANNs). By using Ohm’s Law to apply stored weights to incoming signals, and Kirchoff’s Laws to sum up the results, memristor arrays can accelerate the many multiply-accumulate steps in ANN algorithms. ANNs are being dep... » read more

Lithium-air battery Researchers at the University of Illinois at Chicago and Argonne National Laboratory designed a new lithium-air battery that works in a natural air environment and still functioned after 750 charge/discharge cycles, a record for this battery type. In theory, lithium-air batteries work by combining lithium present in the anode with oxygen from the air to produce lithium p... » read more

World's brightest accelerator Japan’s High Energy Accelerator Research Organization (KEK) is readying what is considered the world’s most luminous or brightest particle accelerator. The system, dubbed the SuperKEKB, combines an electron-positron collider with a new and advanced detector. The storage ring system is designed to explore and measure rare decays of elementary particles, such... » read more

Atomristors for thin memory Engineers at The University of Texas at Austin and Peking University developed a thin memory storage device with dense memory capacity. Dubbed "atomristors," the device enables 3-D integration of nanoscale memory with nanoscale transistors on the same chip. "For a long time, the consensus was that it wasn't possible to make memory devices from materials that were... » read more

Lithium-iron-oxide battery Scientists at Northwestern University and Argonne National Laboratory developed a rechargeable lithium-iron-oxide battery that can cycle more lithium ions than its common lithium-cobalt-oxide counterpart, leading to a much higher capacity. For their battery, the team not only replaced cobalt with iron, but forced oxygen to participate in the reaction process as we... » read more

World’s coldest chip Using a network of nuclear refrigerators, the University of Basel and others claim to have set the record for the world’s coldest chip. Researchers have cooled a chip to a temperature lower than 3 millikelvin. A millikelvin is one thousandth of a kelvin. Absolute zero is 0 kelvin or minus 273.15 °C. In the experiment, researchers used a chip that includes a Coulomb... » read more

Solar jet fuel Researchers at ETH Zurich demonstrated the ability to use solar energy to create the precursor to jet fuel from water and carbon dioxide, a process that could lead to carbon-neutral air travel. The scientists performed 295 consecutive cycles in a 4 kW solar reactor, yielding 700 standard liters of hydrogen and carbon monoxide (syngas), the precursor to kerosene and other liqu... » read more

Piezoelectric, ingestible sensors With an aim to help doctors diagnose gastrointestinal disorders that slow down the passage of food through the digestive tract, MIT and Brigham and Women’s Hospital researchers have built a flexible sensor that can be rolled up and swallowed. Once ingested, the sensor adheres to the stomach wall or intestinal lining, where it can measure the rhythmic con... » read more

Theoretical all-carbon circuits Engineers at the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, the University of Central Florida, and Northwestern University designed a novel computing system made solely from carbon. "The concept brings together an assortment of existing nanoscale technologies and combines them in a new way," said Dr. Joseph S. Friedman, ass... » read more

Dental implants Borrowing some of the same processes used in the semiconductor industry, the Peninsula Schools of Medicine and Dentistry and the University of Plymouth have developed new nanocoating materials for dental implants. Some three million Americans have dental implants, according to the American Academy of Implant Dentistry (AAID). This number is rising by 500,000 a year, accordin... » read more
