Manufacturing Bits: Oct. 19


Solar mini-reactors The University of Amsterdam has developed a standalone solar-powered mini-reactor. The technology could one day serve as an autonomous off-grid photochemistry system for remote locations. The prototype solar reactor measures 0.25 square meters. The system is equipped with a solar cell, which provides the power for the pumps and control system. This solar cell is placed ... » read more

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

5G metasurface antennas At the recent 2021 IEEE 71st Electronic Components and Technology Conference (ECTC), the Institute of Microelectronics of the Chinese Academy of Sciences (CAS) presented a paper on a low-profile broadband metasurface antenna for 5G antenna-in-package applications. The National Center for Advanced Packaging and the University of Chinese Academy of Sciences also contri... » read more

Power/Performance Bits: March 23


Metasurface for optical media Researchers at Purdue University proposed a new way to store information in optical media, such as CDs and DVDs, that could improve both storage capacity and read times. The development focuses on encoding information in the angular position of tiny antennas, allowing them to store more data per unit area. "The storage capacity greatly increases because it is o... » read more

Power/Performance Bits: July 14


5G switches Researchers from the University of Texas at Austin and University of Lille built a new radio frequency switch that could save power in 5G devices when not actively jumping between different networks and spectrum frequencies. “It has become clear that the existing switches consume significant amounts of power, and that power consumed is useless power,” said Deji Akinwande, a ... » read more

Power/Performance Bits: March 24


Backscatter Wi-Fi radio Engineers at the University of California San Diego developed an ultra-low power Wi-Fi radio they say could enable portable IoT devices. Using 5,000 times less power than standard Wi-Fi radios, the device consumes 28 microwatts while transmitting data at a rate of 2 megabits per second over a range of up to 21 meters. "You can connect your phone, your smart devices, ... » read more

Scaling Up Compute-In-Memory Accelerators


Researchers are zeroing in on new architectures to boost performance by limiting the movement of data in a device, but this is proving to be much harder than it appears. The argument for memory-based computation is familiar by now. Many important computational workloads involve repetitive operations on large datasets. Moving data from memory to the processing unit and back — the so-called ... » read more

Manufacturing Bits: Dec. 23


Gallium oxide transistors At the recent IEEE International Electron Devices Meeting (IEDM), Cornell University and Hosei University presented a paper on a gallium oxide vertical transistor with a record breakdown voltage. Crystalline beta gallium oxide is a promising wide bandgap semiconductor material, which is used for power semiconductor applications. Gallium oxide has a large bandgap of... » read more

System Bits: Sept. 11


Everything’s faster in Texas The Frontera supercomputing system was formally unveiled last week at the Texas Advanced Computing Center. The system was deployed in June on the University of Texas at Austin campus. It is the fifth-fastest supercomputer in the world at present and the world's fastest academic supercomputer. Dell EMC and Intel collaborated on fitting out Frontera. Work beg... » read more
