The University of Southampton is storing data onto glass at a density that would squeeze 500Tbyte onto a substrate the size of a CD. Data is written as miniature shapes through the bulk of silica glass using the three spatial dimensions. The shapes have two separate optical characteristics – adding two more dimensions – making this ...

TT Electronics has expanded its WHPC series of surface mount power resistors to include 1W (WHPC0508X), 1.5W (WHPC0612X) and 2W (WHPC1020X chip) sizes. These are the same size as the company’s similarly-sized parts without the ‘X’ suffix, but can handle more power – ‘X’ stands for extra high power. The earlier (non-X) 0612 and 1020 can handle 0.5W and ...

Scientists from Skoltech of Moscow have used a 3D printer to fuse two materials in an alloy whose composition continuously changes from one region of the sample to the other, endowing the alloy with gradient magnetic properties. Despite the nonmagnetic nature of the constituent materials, the alloy exhibits magnetic properties 3D printing tends to use one ...

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have used a technique called cryo-forging to manipulate pure titanium at nanoscale dimensions at ultra-low temperatures to produce extra-strong “nanotwinned” titanium without sacrificing ductility. “This study is the first time someone has produced a pure nanotwinned structure in bulk material,” says Andrew Minor, the study’s project lead and ...
