Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a microminiaturized device that can make complex viscosity measurements"”critical data for a wide variety of fields dealing with things that have to flow"”on sample sizes as small as a few nanoliters. Currently a table-top prototype, the NIST rheometer could be a particularly valuable tool for biotechnologists studying minute quantities of complex materials that must function in confined...

Materials scientists have known that a metal's strength (or weakness) is governed by dislocation interactions, a messy exchange of intersecting fault lines that move or ripple within metallic crystals. But what happens when metals are engineered at the nanoscale? Is there a way to make metals stronger and more ductile by manipulating their nanostructures? Brown University scientists may have figured out a way. In a paper published in Nature, Huajian Gao and researchers from the University of...

In a paper appearing in the Feb. 24 issue of the Proceedings of the Royal Society of London A, Virginia Tech Engineering Science and Mechanics Professor Hassan Aref, and his colleague Johan Roenby at the Technical University of Denmark shed new light on the chaotic motion of a solid body moving through a fluid. They claim to have discovered two basic mechanisms that lead to chaotic motion of the body as it interacts with its vortex wake. The work may lead to better understanding and control...

Researchers at the California Institute of Technology (Caltech) have developed a way to make some notoriously brittle materials ductile"”yet stronger than ever"”simply by reducing their size. The work, by Dongchan Jang, senior postdoctoral scholar, and Julia R. Greer, assistant professor of materials science and mechanics at Caltech, could eventually lead to the development of innovative, superstrong, yet light and damage-tolerant materials. These new materials could be used as...

Magnetorheological (MR) fluids are smart materials whose flow/viscosity properties can be modified by applying an electric field. These changes in viscosity occur within a fraction of a millisecond "“ far faster than conventional mechanical means "“ and can be used to effectively control vibrations in applications dealing with actuation, damping, robotics and mechatronics. In this study published in AZojomo*, researchers Jorge A. Cort©s R., Leopoldo S....
