HELSINKI, May 27, 2014 /PRNewswire/ -- The industrial measurement specialists at ProtoRhino (http://www.protorhino.com/) are excited to announce the release of FlexRHINO DynaMat, a new device that will help engineers and researchers better understand the processes leading to material weakening and failure. DynaMat is unique in that it enables the observation of microscopic events, which have always been difficult, if not impossible, to detect in real-time. "The response to DynaMat...

Strengthening Steel Without Sacrificing Ductility
2014-04-09 16:20:21

Brown University Researchers from Brown University and universities in China have found a simple technique that can strengthen steel without sacrificing ductility. The new technique, described in Nature Communications, could produce steel that performs better in a number of structural applications. Strength and ductility are both crucial material properties, especially in materials used in structural applications. Strength is a measure of how much force is required to cause a material...

Advances In Glass Alloys Lead To Strength, Flexibility
2014-03-04 12:36:16

DOE/Los Alamos National Laboratory What do some high-end golf clubs and your living room window have in common? The answer is glass, but in the golf clubs' case it's a specialized glass product, called metallic glass, with the ability to be bent considerably and spring back into its original form. Your windows, as you know, aren't quite as forgiving of a sudden impact, and they shatter – they are brittle, as opposed to ductile, or more flexible products. For the golf clubs, however, a...

When deciding what materials to use in building something, determining how those materials respond to stress and strain is often the first task. A material’s macroscopic, or bulk, properties in this area — whether it can spring back into shape, for example — is generally the product of what is happening on a microscopic scale. When stress causes a material’s constituent molecules to rearrange in a way such that they can't go back to their original positions, it is known as “plastic...

From the production of tougher, more durable smart phones and other electronic devices, to a wider variety of longer lasting biomedical implants, bulk metallic glasses are poised to be  mainstay materials for the 21st Century. Featuring a non-crystalline amorphous structure, bulk metallic glasses can be as strong or even stronger than steel, as malleable as plastics,  conduct electricity and resist corrosion. These materials would seem to have it all save for one problem: they are often...

Firing Temperature Determines Whether Glass Will Bend Or Break
2013-02-28 16:24:11

Lee Rannals for redOrbit.com — Your Universe Online Researchers have found a way to determine whether glass will be brittle, or will have the ability to bend without breaking. The team wrote in the journal Nature Communications about how they've identified a temperature that allows you to determine whether you will be forming a brittle piece of glass, or ductile, which refers to a piece of glass' toughness. There is a temperature at which glass can become too viscous for...

Archeologists Unearth Alien-Like Skulls In A Mexico Cemetery
2012-12-27 12:47:05

[Watch Video: Alien-Like Skulls Unearthed In Mexican Cemetery] Lee Rannals for redOrbit.com — Your Universe Online Archeologists have unearthed what looks like a cone-shaped alien skull from 1,000 years ago in Mexico. The skull, which dates from 945 A.D. to 1308 A.D., was discovered accidentally while digging an irrigation system in the northwest state of Sonora in Mexico. Cristina Garcia Moreno, who worked on the project with Arizona State University, explained that 13 of...

When materials are stressed, they eventually change shape. Initially these changes are elastic, and reverse when the stress is relieved. When the material's strength is exceeded, the changes become permanent. This could result in the material breaking or shattering, but it could also re-shape the material, such as a hammer denting a piece of metal. Understanding this last group of changes is the focus of research from a team including Carnegie's Ho-kwang "Dave" Mao. Their breakthrough...

Harnessing Power By Funneling Solar Energy
2012-11-26 12:53:51

Michael Harper for redOrbit.com — Your Universe Online The concept is a simple one, borrowing from some very elementary principles. For instance, everyone knows the best way to capture and contain the most of an element or substance is with a funnel. These cones make it easier to put oil in our cars or fill small glass shakers from a larger bag of sugar. Now, some MIT engineers have worked out a computational model which shows how solar energy can be more or less funneled...

Plagued by a life ruled by the stress of a birth-defect, surviving abuse, alcoholism, and unemployment, author Richard Murphy dug deep into his source of strength, and found inspiration to carry on and overcome stress. After years of studying, under martial art masters and native elders as well as through life´s experiences, Murphy felt driven to educate people about the strength they have within themselves. His methods can be found in his book, Change Your Stress: Restore Your Freedom...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
