If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce nanoparticles to assemble themselves into complex arrays. By adding specific types of small molecules to mixtures of nanoparticles and polymers, the...

Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report. Applications for force-directed cell differentiation include therapeutic cloning and regenerative medicine. "Our results suggest that small forces may indeed play critical roles in inducing strong biological responses in embryonic stem cells, and in shaping embryos during their early development," said Ning...

Nanoscale friction and manipulation Nanotubes and nanowires are promising building blocks for future integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical nanodevices. But some fundamental issues remain to be resolved "“ among them, how to position and manipulate the tiny tubes. Publishing in the journal Nature Materials this week, researchers from four different institutions report measuring different friction forces when a carbon nanotube...

Researchers from the Eindhoven University of Technology and the University of Ulm have made the first high-resolution 3D images of the inside of a polymer solar cell. This gives them important new insights in the nanoscale structure of polymer solar cells and its effect on the performance. The findings were published online in Nature Materials on Sunday September 13. The investigations shed new light on the operational principles of polymer solar cells. Cost-effective, flexible and...

Scientists are closer to understanding how to grow replacement bones with stem cell technology, thanks to research published today in the journal Nature Materials. Many scientists are currently trying to create bone-like materials, derived from stem cells, to implant into patients who have damaged or fractured bones, or who have had parts of diseased bones removed. The idea is that, ultimately, these bone-like materials could be inserted into cavities so that real bone could meld with it and...

Review article calls for measures to enable safe design of nanomaterials The recent explosion in the development of nanomaterials with enhanced performance characteristics for use in commercial and medical applications has increased the likelihood of people coming into direct contact with these materials. There are currently more than 800 products on the market "” including clothes, skin lotions and cleaning products "” claiming to have at least one nanocomponent, and therapeutic...

Researchers at New York University have created a method to precisely bind nano- and micrometer-sized particles together into larger-scale structures with useful materials properties. Their work, which appears in the latest issue of the journal Nature Materials, overcomes the problem of uncontrollable sticking, which had been a barrier to the successful creation of stable microscopic and macroscopic structures with a sophisticated architecture. The long-term goal of the NYU researchers is to...

Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist. They are potential cornerstones in future magnetic data storage and spintronic devices provided a simple and fast way can be found to turn their electric and magnetic properties on and off. In a promising new development, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) working with a prototypical multiferroic have...

Yale researchers describe a breakthrough in safe and effective administration of potential antiviral drugs "” small interfering RNA (siRNA) molecules that silence genes "” the first step in development of a new kind of treatment for sexually transmitted diseases (STDs). The work is reported May 4 as an advance online publication of Nature Materials. "RNA interference is a promising approach for prevention and treatment of human disease," said lead author Kim Woodrow, Yale...

Two teams of scientists have developed a cloak that renders objects invisible to near-infrared light, BBC News reported. The new technology, however, does not contain metals unlike previous such "cloaks" that resulted in imperfect cloaking because of losses of light. Researchers say that since the approach can be scaled down further in size, the new technology is a major step towards a cloak that would work for visible light. John Pendry from Imperial College London first theorized a cloak...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
