Want a tennis racket that propels balls faster than a race car or a sturdy ship hull that never rusts? Finding the recipes for such remarkable materials – called amorphous metals – should be easier using a new computational approach developed by Carnegie Mellon University physicist Michael Widom.
Described in an upcoming issue of Phys. Rev. B (September 1, 2004), this method already has been used to virtually generate recipes for more than 1,700 structures, many of which have never before been analyzed. The novel approach should prove valuable in guiding future bench testing and sparing countless hours of laboratory trial and error to generate amorphous metals.
Alloys for everyday materials like stainless steel are made by combining a metal with other elements. The resulting metals crystallize into lattices in which atoms line up in orderly arrangements. Defects in these crystals inevitably weaken materials made from them, leading to fractures and corrosion.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
