Research Bits: April 19


Processor power prediction Researchers from Duke University, Arm Research, and Texas A&M University developed an AI method for predicting the power consumption of a processor, returning results more than a trillion times per second while consuming very little power itself. “This is an intensively studied problem that has traditionally relied on extra circuitry to address,” said Zhiy... » read more

Battery Management Getting Competitive For EVs


The success or failure of future electric vehicles will depend on where and how those cars are used, as well as significant advances in battery materials, energy density, and some very complex battery management systems. Battery power needs to be balanced, stored for extended times, and delivered to wherever it is needed most in real time. This is a huge challenge, and nearly everything in a... » read more

Electric Planes Taking Off


As the aeronautics industry and aviation startups design and test zero-emissions aircraft, they are solving problems beyond just adapting to fuel sources that cut greenhouse gas emissions. Problems of weight, noise, redundancy, refueling, cost, and turnaround time are being tackled one airline seat at time. Powerful tools can help aircraft designers look at the aircraft system as a whole, fe... » read more

Research Bits: March 29


Brain-like AI chip Researchers from Purdue University, Santa Clara University, Portland State University, Pennsylvania State University, Argonne National Laboratory, University of Illinois Chicago, Brookhaven National Laboratory, and University of Georgia built a reprogrammable chip that could be used as the basis for brain-like AI hardware. “The brains of living beings can continuously l... » read more

Technical Paper Round-Up: March 29


Improving batteries, ultra low-power photonic edge computing, SLAM, Tellurium for 2D semiconductors, and reservoir computing top the past week's technical papers. The focus on energy is critical as the edge buildout continues and more devices are connected to a battery, while research into new architectures and materials that will continue scaling and improve performance per watt continue at th... » read more

Native lattice strain induced structural earthquake in sodium layered oxide cathodes (batteries)


Abstract "High-voltage operation is essential for the energy and power densities of battery cathode materials, but its stabilization remains a universal challenge. To date, the degradation origin has been mostly attributed to cycling-initiated structural deformation while the effect of native crystallographic defects induced during the sophisticated synthesis process has been significantly ove... » read more

Chiplets Enter The Supercomputer Race


Several entities from various nations are racing each other to deliver and deploy chiplet-based exascale supercomputers, a new class of systems that are 1,000x faster than today’s supercomputers. The latest exascale supercomputer CPU and GPU designs mix and match complex dies in advanced packages, adding a new level of flexibility and customization for supercomputers. For years, various na... » read more

Batteries Have Moving Parts


The race is on to make lithium-ion batteries safer, to increase the amount of energy that can be drawn out of these devices, and to reduce the time it takes to charge them up again. Transistors and other electronic components depend on the movement of electrons, which are effectively massless and dimensionless relative to the semiconductor, metal, and dopant atoms that surround them. A batte... » read more

Nanoporous Dielectric Resistive Memories Using Sequential Infiltration Synthesis


Abstract "Resistance switching in metal–insulator–metal structures has been extensively studied in recent years for use as synaptic elements for neuromorphic computing and as nonvolatile memory elements. However, high switching power requirements, device variabilities, and considerable trade-offs between low operating voltages, high on/off ratios, and low leakage have limited their utility... » read more

Manufacturing Bits: Aug. 31


X-ray nanotomography The U.S. Department of Energy’s (DOE) Argonne National Laboratory has developed a new method for improving the resolution of hard X-ray nanotomography. In general, tomography involves a system, which takes images or cross sections of a sample using X-rays or ultrasound. The images are then re-created in the form of a 3D model. One common form is called micro-comput... » read more
