Highlighting another challenge to the development of quantum computers, theorists at the National Institute of Standards and Technology (NIST) have shown that a type of software operation, proposed as a solution to fundamental problems with the computers? hardware, will not function as some designers had hoped.
By combining the results of a number of powerful techniques for studying material structure at the nanoscale, a team of researchers from the National Institute of Standards and Technology (NIST), working with colleagues in other federal labs and abroad, believe they have settled a long-standing debate over the source of the unique electronic properties of a material with potentially great importance for wireless communications.
Pittcon 2009 reported today that 19,018 attendees from 90 countries participated in the annual Conference and Exposition, which was held in Chicago, Illinois, from March 8 to March 13. The scientific event was marked by a 6% increase in conferees over Pittcon 2008.
Certain fish species blend with their environment by changing color like chameleons. In two recent papers, Sandia researchers have demonstrated that, in theory, they could produce a similar color change to enable synthetic or hybrid materials to change color like fish do.
Researchers at the University of Arkansas have shown that changing the chirality, or direction of spin, of a nanoscale magnetic vortex creates an electric pulse, suggesting that such a pulse might be of use in creating computer memory and writing information.
A new high-energy cathode material that can greatly increase the safety and extend the life-span of future lithium batteries has been developed through the close international collaboration of researchers led by Argonne National Laboratory and Hanyang University in South Korea.
A Colorado State University mechanical engineering professor is in the first year of a new study to determine whether nanotubes on titanium implants can deliver chemotherapy drugs and antibiotics directly to skeletal implants, limiting the spread of drugs throughout the body and reducing side effects on patients.
In what way will nanotechnology affect social life, the working and consumer environment, and our welfare systems? And to what extent are we prepared to accept such changes? Prominent experts will be discussing these issues at the SIZE MATTERS 2009 conference on June 17-18, 2009 from the perspective of the natural sciences, medicine, philosophy, theology and law.
As well as their application in research, medical diagnosis and treatment, aptamers are also interesting as a basis for biosensors for use in environmental analysis because their characteristics enable them to identify and bind target molecules as surely as a key fits a lock.
The IEEE Standards Association (IEEE-SA) will participate as an exhibitor at the NSTI Nanotech 2009 Conference and Expo at the George R. Brown Convention Center in Houston, TX from 3-7 May 2009 at Booth 630.
