Finding new, low-cost ways to make better metal alloys and composites is one of the holy grails of the materials research world. Scientists at the U.S. Department of Energy's Pacific Northwest ...

(Phys.org)—A team of researchers from China and the U.S. has devised a relatively simple means for measuring the shear forces that exist between sheets of graphene and other materials. In their paper ...

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 ...

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.

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 ...

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 ...

THIS is a reprint in book-form, with additions, of a series of articles which appeared in Engineering in the autumn of 1906. Those who have had any experience of such work will know how tedious is the ...
