Study analyzes the keys to fragmentation of metallic materials

Scientists have analyzed the mechanisms behind the dynamic fragmentation of ductile metallic materials that exhibit large permanent deformations when subjected to severe mechanical loading. Previously, it was thought that ...

Reusing electric pylons to design the roof of a train station

For his Master's project, Joseph Desruelle devised a plan to reuse steel bars from dismantled electricity pylons to make a new roof for the Lausanne train station. This approach is still theoretical, but reusing materials ...

Origami-inspired self-locking foldable robotic arm

A research team of Seoul National University led by Professor Kyu-Jin Cho has developed an origami-inspired robotic arm that is foldable, self-assembling and also highly-rigid. (The researchers include Suk-Jun Kim, Dae-Young ...

Building blocks to create metamaterials

Engineers at Caltech and ETH Zürich in Switzerland have created a method to systematically design metamaterials using principles of quantum mechanics.

Team develops innovative, ideal liquid-repellent surfaces

On liquid-repellent surfaces, liquid droplets bounce away instead of being stuck. These surfaces are important in many fields, such as water-repellent clothes and anti-fouling kitchenware. Used as drag-reduction coatings ...
