Two 200nm-wide spectroscopy images of a sample of twisted double bilayer graphene. The left image depicts the triangle lattice of the moiré material, which has three-fold symmetry and can be rotated 120° in any direction without changing the image. The right image was taken at a different energy and can now only be rotated by […]
These cryo-EM images of electrolyte clinging to holes in a sample grid show why its important to blot away excess electrolyte before freezing and imaging the samples. At top, excess electrolyte has frozen into a thick layer (right) and sometimes even formed crystals (left), blocking the microscopes view of the tiny circular samples beneath. After […]
Lee Spring, a manufacturer of stock and custom springs, has acquired Dayon Manufacturing. Located in Farmington, Connecticut, and established in 1957, Dayon Manufacturing specializes in the design, engineering, and manufacturing of custom miniature and micro springs. Steve Kempf, CEO of Lee Spring, commented, “The acquisition of Dayon Manufacturing, which has over a half century of […]
Learning Objectives Aixemtec GmbH in Herzogenrath, Germany, develops automated solutions for the precision assembly of electro-optical systems. Technology advances helped Aixemtec saved more than 60% of space. Aixemtec retained modularity by using distributed clocks and fast control processes in the sub-millisecond range. PC-based controls and integrated machine vision are among technologies helping Aixemtec GmbH […]
While palletizing and depalletizing products may sound like a simple task, the specifics can be rather complex. From the material handling robot with its end-of-arm tooling (EOAT) and load distribution requirements to the product itself, there are a lot of areas to consider in order to meet crucial cycle times. 1. High speed. The speed […]
Increased package deliveries, especially in pandemic times, can put an undue stress on mail carriers and warehouse workers. But what if they could get help from some four-legged friends? Led by assistant professor Quan Nguyen, USC Viterbi doctoral students Mohsen Sombolestan and Yiyu Chen created a control algorithm that allows quadruped robots to adapt to […]
Ceva has revamped its NeuPro AI accelerator engine IP, adding specialized co-processors for Winograd transforms and sparsity operations and a general-purpose vector processing unit alongside the engine’s MAC array. The new generation engine, NeuPro-M, can boost performance 5-15X (depending on the exact workload) compared to Ceva’s second generation NeuPro-S core (released Sept 2019). For example, ResNet-50 […]
Samsung today announced an MRAM innovation, claiming the world’s first in-memory computing based on MRAM capable of performing both data storage and data computing within a single memory network. The company claims its MRAR array chip is the next step to realizing low-power AI chips. Use of in-memory computing architectures has increased over the years […]
Taiwan Semiconductor Manufacturing Co. (TSMC) once again plans a boost in capital expenditures. This new round calls for as much as $44 billion in 2022 to meet demand the company believes could grow by up to 20 percent during the next few years. Chips used in high-performance computing (HPC) and smartphones, each accounting for about […]
Thermal considerations are a major part of many designs. Whether it’s minimizing or managing dissipation, access to various cooling techniques, or even creating cold for refrigeration or superconductivity, heat-related issues are pervasive in engineering considerations. When engineers think thermal, it’s usually in the context of a broad macroscopic sense. In contrast, many theoretical physicists look […]
