Metals consist of stacked layers of tightly packed, interacting atoms arranged in geometric patterns. Each of these atoms contains a small number of loosely held electrons in its outer shell. When ...

For the first time, it is possible to create complex nanoscale metal structures using 3-D printing, thanks to a new technique developed at Caltech. The process, once scaled up, could be used in a wide ...

Nature’s porous materials, bone, coral and cork, are synonymous with strong and lightweight structures. Driven by the prospect of producing a family of materials with unique combinations of properties ...

Although the world of 3D printing is hurtling through milestones at the moment, to a large extent the technology still remains in its infancy. If you thought it was all Etsy jewellery and plastic toys ...

Metals have vital roles in both the mechanism and architecture of biological macromolecules. Yet structures of metal-containing macromolecules in which metals are misidentified and/or suboptimally ...

One of the most well-known and intricately detailed types of 3D-printing, “vat photopolymerization,” uses light to form structures from photo-sensitive resin. A new study has found a way to leverage ...

A metal is comprised of many individual crystals, or grains. These crystals are held together by electrons in the same way that electrons hold the atoms within each crystal together. For more on this ...
