Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is known as the diffraction limit of light. Super-resolution imaging techniques, ...

The force needed to slide sheets of graphene across each other has been measured using a new technique that involves blowing air bubbles made of the material. Developed by Zhong Zhang of the National ...

Tactical Haptics recently revealed the SaberGrip controller, which amplifies VR simulations' immersion with realistic force feedback. The controllers utilize sheer forces to simulate any handle ...

Left: The gelation mechanism through metal coordination to the pseudopolyrotaxanes; the metal ions are shown as yellow spheres. In the lower panel, which represents the hydrogel, the pseudorotaxanes ...

The transverse load P will produce a shear force V in the positive y direction on a mathematical cut through the beam at point “a”. This shear force is directly responsible for the shear stress τ on ...
