Applied scientists at Harvard University in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, highly directional semiconductor lasers with a much smaller beam divergence than conventional ones. The innovation opens the door to a wide range of applications in photonics and communications. Harvard University has also filed a broad patent on the invention.
Laser technology has revolutionised the world of medicine in ways never before thought of. More and more often the scalpel is giving way to a new generation of lasers. Now the FAST-DOT project, backed by the EU with EUR 10.1 million in financing, is underway to develop a new line of lasers for biomedical applications.
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights.
"TIGA," the new high-tech imaging center at the University of Heidelberg founded in cooperation with the Japanese company Hamamatsu, provides deep insights: a high-tech robot makes it possible for the first time to automatically reproduce and evaluate tissue slices only micromillimeters thick - an important aid for researchers in understanding cancer or in following in detail the effect of treatment on cells and tissue.
A new paper by a team of researchers led by University of Notre Dame physicist Bolizsár Jankó provides an overview of research into one of the few remaining unsolved problems of quantum mechanics.
The odd behavior of a molecule in an experimental silicon computer chip has led to a discovery that opens the door to quantum computing in semiconductors.
When lasers illuminate material it usually warms up. Therefore laser beams are, for example, used for cutting sheet steel, for welding or even as scalpels. But this effect can also be reversed
Customized microscopic magnets that might one day be injected into the body could add color to magnetic resonance imaging (MRI), while also potentially enhancing sensitivity and the amount of information provided by images.
For solar cells to be useful, they need to be cheap, cover a large area, and be physically flexible, which are benefits of using solution-processed photovoltaics. Much of the current research in solution-processed photovoltaics is dedicated to optimizing solar conversion efficiency in the visible region of the spectrum.
The exciting progress was made in the important field of quantum optics and discussed recently at a high level conference organised by the European Science Foundation in collaboration with the Fonds zur Förderung der wissenschaftlichen Forschung in Österreich (FWF) and the Leopold-Franzens-Universität Innsbruck (LFUI).
