Hybrid Chips can run AI on Battery Powered Devices
Smartwatches and other battery-powered electronics would be even smarter if they could run AI algorithms. But efforts to build AI-capable chips for mobile devices have so far hit a wall - the so-called "memory wall" that separates data processing and memory chips that must work together to meet the massive and continually growing computational demands imposed by AI.

Innovative Battery Chemistry Revolutionises Zinc-Air Battery
High-performance, eco-friendly, safe and at the same time cost-effective: the zinc-air battery is an attractive energy storage technology of the future. Until now, the conventional zinc-air battery has struggled with a high chemical instability, parasitic reactions which rooted in the usage of alkaline electrolytes lead to electrochemical irreversibility.

A Defect-resistant Superalloy for 3D Printing
In recent years, it has become possible to use laser beams and electron beams to "print" engineering objects that have complex shapes that could not be achieved by conventional manufacturing routes. The additive manufacturing process, known widely as 3D printing, for metallic materials involves melting and fusing fine-scale powder particles — each about ten times finer than a grain of local beach sand — in sub-millimeter-scale "pools" created by focusing a laser or electron beam on the material.
