Researchers have discovered that ultrasonic waves can be used to grab several microparticles at a time, effectively creating a pair of invisible 'ultrasonic hands' that can move tiny objects, such as cells, under a microscope.
The incorporation of nanoparticles of gold or silver into conventional ink, the same ink as in our ballpoints or pens, is an advanced solution in identifying molecules in fields such as medical diagnosis, biology, the environment, safety, etc.
Due to the delocalization of molecular orbitals valence shell spectroscopy does not allow distinction between individual atoms. Here, the authors show that for photoionization the difference in mass - and hence recoil momentum - between atoms in a diatomic molecule allows site selective emission to be observed.
The University of Chicago's Institute for Molecular Engineering will lead a team of researchers from five universities in an ambitious five-year, $6.75 million project to create a new class of quantum devices that will allow communication among quantum computers.
Researchers have taken a step toward practical applications for 'hyperbolic metamaterials', ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells.
As part of the Communication on the Second Regulatory Review on Nanomaterials, the European Commission has announced to launch an impact assessment to identify and develop the most adequate means to increase transparency and ensure regulatory oversight on nanomaterials.
A device created by electrical engineers uses a thin film of vanadium dioxide on a titanium dioxide substrate to create an oscillating switch. When a second similar oscillating system was added, over time the two devices would begin to oscillate in unison. This coupled system could provide the basis for non-Boolean computing.
Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels.
Physicists have developed a new ultrafast light source for observing electron motion in molecules - made up of nuclei and electrons - at the point before the nuclei start to move. By being able to observe what actually happens, scientists can begin to understand how an electron interacts with other electrons, which may help improve the efficiency of solar cells.
The ability to transfer a gene or DNA sequence from one animal into the genome of another plays a critical role in a wide range of medical research - including cancer, Alzheimer's disease, and diabetes.
