A team of scientists has just carried out the first detailed experimental study regarding photoluminescence up-conversion in semiconductor nanostructures. Based on this, the development of a vibration-free cooling of semiconductors might be possible.
To meet the demand for batteries having higher energy density and improved cycle characteristics, in recent years, a great deal of attempt has been made to develop new electrode materials or design new structures of electrode materials.
It has been little more than 20 years since the discovery of buckyballs, hollow spherical molecules made entirely of carbon atoms, which serve as the starting point for this field of study. In 1996, Richard Errett Smalley won the Nobel Prize in Chemistry for the breakthrough. While there have been accomplishments at the pinnacle of academics in this emerging field, there is still a need for more accessible introductory curricula.
A new technique for attaching light-sensitive organic molecules to metal surfaces allows the molecules to be switched between two different configurations in response to exposure to different wavelengths of light.
Researchers finally determined what makes diamond films such slippery customers, settling a debate on the scientific origin of its properties and providing new knowledge that will help create the next generation of super low friction materials.
A team of University of British Columbia researchers has developed a technique that controls the number of electrons on the surface of high-temperature superconductors, a procedure considered impossible for the past two decades.
The search for these natural but 'invisible' nanoparticles is important. If they can be proved to exist, the knowledge will help give us a deeper understanding of how gold can be transported and deposited by geological processes, and therefore help explorers to find new gold deposits in Australia.
Applications of nanotechnology to electronics, photonics and renewable energy will be the focus of a joint forum to be held from August 10 to 14, 2009 at McMaster University in Hamilton, Ontario, Canada.
