Designing new materials depends upon understanding the properties of today's materials. One such material, Nafion ©, is a polymer that efficiently conducts ions (a polymer electrolyte) and water through its nanostructure, making it important for many energy-related industrial applications, including in fuel cells, organic batteries, and reverse-osmosis water purification. But since Nafion was invented 50 years ago, scientists have only been able to speculate about how to...

New method marks advance in efforts to develop a replacement for silicon in high-performance electronics University of Houston researchers have developed a method for creating single-crystal arrays of the material graphene, an advance that opens the possibility of a replacement for silicon in high-performance computers and electronics. The work by UH researchers and their collaborators is featured on the cover of the June issue of Nature Materials. Graphene is a one-atom-thick layer of carbon...

Scientists from Finland and France have developed a new synchrotron X-ray technique that may revolutionize the chemical analysis of rare materials like meteoric rock samples or fossils. The results have been published on 29 May 2011 in Nature Materials as an advance online publication. Life, as we know it, is based on the chemistry of carbon and oxygen. The three-dimensional distribution of their abundance and chemical bonds has been difficult to study up to now in samples where these...

The physical forces that guide how cells migrate"”how they manage to get from place to place in a coordinated fashion inside the living body"” are poorly understood. Scientists at the Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC) have, for the first time, devised a way to measure these forces during collective cellular migration. Their surprising conclusion is that the cells fight it out, each pushing and pulling on its neighbors...

Boston College and MIT researchers see broad residential and industrial applications High-performance nanotech materials arrayed on a flat panel platform demonstrated seven to eight times higher efficiency than previous solar thermoelectric generators, opening up solar-thermal electric power conversion to a broad range of residential and industrial uses, a team of researchers from Boston College and MIT report in the journal Nature Materials. Two technologies have dominated efforts to harness...

For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue. Developing this nanofiber sphere as a cell carrier that simulates the natural growing environment of the cell is a very significant advance in tissue repair, says Peter Ma, professor at the University of Michigan School of Dentistry and...

A new way of understanding the structure of proteins, polymers, minerals, and engineered materials will be published in the May 2011 issue of the journal Nature Materials. The discovery by two Penn State University researchers is a new type of symmetry in the structure of materials, which the researchers say greatly expands the possibilities for discovering or designing materials with desired properties. The research is expected to have broad relevance in many development efforts involving...

A team of scientists from Princess Margaret Hospital have created an organic nanoparticle that is completely non-toxic, biodegradable and nimble in the way it uses light and heat to treat cancer and deliver drugs. (A nanoparticle is a minute molecule with novel properties). The findings, published online today in Nature Materials (DOI: 10.1038/NMAT2986) are significant because unlike other nanoparticles, the new nanoparticle has a unique and versatile structure that could potentially change...

New stretchable electronics device promises to make cardiac ablation therapy simpler In an improvement over open-heart surgery, cardiologists now use catheters to eliminate damaged heart tissue in certain patients, such as those with arrhythmias. But this, too, can be a long and painful procedure as many catheters, with different functions, need to be inserted sequentially. Now an interdisciplinary team including researchers from Northwestern University has developed one catheter that can do...

Amorphous palladium-based alloy demonstrates unprecedented level of combined toughness and strength; could be of use in biomedical implants Glass is inherently strong, but when it cracks or otherwise fails, it proves brittle, shattering almost immediately. Steel and other metal alloys tend to be tough"”they resist shattering"”but are also relatively weak; they permanently deform and fail easily. The ideal material, says Marios Demetriou, a senior research fellow at the California...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
