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 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 ...

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: Reyhaneh Farimani, University of ...

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.

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 ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...

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 ...

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: They showed that for the simplest ...

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 ...
