Led by Sri Sridhar, Distinguished Professor and Chair of Physics at Northeastern University, a team of researchers from the university's Electronic Materials Research Institute has published research that has resulted in a new breakthrough in the field of nanophotonics, the study of light at the nanoscale level. Utilizing nanomanufacturing processes, the researchers were able to develop an optical microlens with a step-like surface, instead of a smooth surface, that has the capacity to operate at infrared frequencies using the novel phenomenon of negative index refraction.
The Magellan XHR SEM allows scientists and engineers to quickly see things they could not see before, such as 3D surface images at many different angles and at resolutions below one nanometer (about the size of ten hydrogen atoms, side-by-side).
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.
Specialised Imaging Ltd. has announced the availability of a new technical report* demonstrating the considerable utility of a simultaneous framing and streak camera system in visualising nanoscale biomedical events.
"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.
Researchers at the U.S. Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) have won six R+D 100 Awards for innovative technologies in areas ranging from national security to the advanced materials industry.
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.
Nikon, Inc. today introduced the new PC-E Micro NIKKOR 45mm f/2.8D ED and PC-E Micro NIKKOR 85mm f/2.8D lenses, expanding a series of lenses that allow photographers to effectively correct perspective and/or depth-of-field to push creative boundaries.
In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. This breakthrough in efficiency without the use of volatile organic solvents will make it possible to pursue large scale, outdoor practical application of lightweight, inexpensive, flexible dye-sensitized solar films that are stable over long periods of light and heat exposure.
Engineers working in optical communications bear more than a passing resemblance to dreamers chasing rainbows.
