New steel for better electric motors under development

Within a few years, the U.S. Department of Energy wants plug-in electric vehicles to be just as affordable and convenient as the internal-combustion machines most of us drive today. But we're not...

Mechanical behavior of tiny structures is affected by atomic defects

An international team of scientists with participation from the University of Göttingen, the Indian Institute of Science, Bangalore, Pennsylvania State University, and Wright State University has measured the mechanics of tiny...

Nanotech could give us safer, greener diapers and sanitary products

A new material made of tiny nanofibers could replace potentially harmful materials found in diapers and sanitary products, according to new research published in Applied Materials Today. The authors of the new...

Scientists put a new twist on artificial muscles

In recent years, researchers at The University of Texas at Dallas and colleagues at the University of Wollongong in Australia have put a high-tech twist on the ancient art of fiber...

Crystalline fault lines provide pathway for solar cell current

A team of scientists studying solar cells made from cadmium telluride, a promising alternative to silicon, has discovered that microscopic "fault lines" within and between crystals of the material act as...

Diamond proves useful material for growing graphene

Graphene is the stuff of the future. For years, researchers and technologists have been predicting the utility of the one-atom-thick sheets of pure carbon in everything from advanced touch screens and...

Similar nanomaterials behave differently: Why?

Nanotubes can be used for many things: electrical circuits, batteries, innovative fabrics and more. Scientists have noted, however, that nanotubes, whose structures appear similar, can actually exhibit different properties, with important...

Tuning the instrument: Spider webs as vibration transmission structures

Two years ago, a research team led by the University of Oxford revealed that, when plucked like a guitar string, spider silk transmits vibrations across a wide range of frequencies, carrying informati..
