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 ...

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The intensity of a volcanic eruption is shaped by how many gas bubbles develop ...

Models that inform how magma moves and volcanic eruptions unfold may need an update, according to a new study. It reports that gas bubbles in magmas can form through the mechanical forces of shear as ...

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, ...

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 ...

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 ...

Fluid shear stress from blood flow and circumferential stretch of vessel walls from blood pressure are important regulatory factors that control the morphogenesis and physiology of blood vessels.

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.

In a new study, researchers show that gas bubbles can form in the rising magma not only due to a drop in pressure but also due to shear forces. If these gas bubbles grow in the volcanic vent early on ...
