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, ...

Supercoiled DNAs varying from 281 to 5302 bp were subjected to shear forces generated by aerosolization or sonication. DNA shearing strongly correlated with length. Typical sized plasmids (⩾3000 bp) ...

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 ...

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 ...

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 ...

Shear force is any force corresponding to a material’s surface. In liquid, for example, this leads to friction between fluid particles, leading to particle size reduction. In high shear mixing, shear ...

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 ...

Abstract: Delamination of rigid objects from an elastic substrate with finite thickness is a fundamental problem underlying applications such as marine fouling release coatings or anti-icing coatings.

Say we consider a beam made up of thin layers (laminae) aligned with the longitudinal axis of the beam, and for which the laminae can slide with respect to each other along the longitudinal axis as ...
