An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...

City University of Hong Kong researchers have accidentally discovered a first-of-its-kind alloy that retains its stiffness instead of softening as the temperature rises. Indeed, high-entropy Elinvar ...

The stiffness of the high-entropy Elinvar alloy remains invariant to temperature. Metals usually soften when they expand under heating, but a research team led by a City University of Hong Kong (CityU ...

Your legs are like springs. When you run, you stretch those springs -- in particular the Achilles tendon, and to a lesser extent the arch of the foot -- and store energy that's then released to power ...

Energy harvesting, an eco-friendly technology, extends beyond solar and wind power in generating electricity from unused or discarded energy in daily life, including vibrations generated by passing ...

The paper is about invariants of networks by labeling and relabeling its nodes or arcs. These invariants can be used to classify networks as to their complexity, or to distinguish non-isomorphic ...

The term 'elastic protein' applies to many structural proteins with diverse functions and mechanical properties so there is room for confusion about its meaning. Elastic implies the property of ...

Be it springs for absorbing energy, buffers for mechanical energy storage, or flexible structures in robotics or energy-efficient machines: Storage of mechanical energy is required for many ...
