Electrophotography techniques such as laser printing or photocopying involve the transfer of charged microparticles of toner or ink onto a rotating drum using electric fields. The microscopic electrostatic interactions between ...
(Phys.org) —Nano-sized crystals of magnetic material can be found in a wide variety of organisms. Among the most studied are magnetotactic bacteria, which can orient and navigate using biosynthesized magnetosomes. These ...
In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate ...
Japanese computer scientists have developed a special purpose computer that can project high-quality three-dimensional (3-D) holography as video. The research team led by Tomoyoshi Ito, who is a professor at the Institute ...
Biologists commonly use fluorescence microscopy due to the molecular specificity and super-resolution of the technique. However, the method is withheld by imaging limits. In a new report on Science Advances, Matz Liebel and ...
Metasurfaces are optically thin metamaterials that can control the wavefront of light completely, although they are primarily used to control the phase of light. In a new report, Adam C. Overvig and colleagues in the departments ...
We seem to be fascinated by holograms or at least the promise of what they can do. Think the famous Princess Leia projection in Star Wars; holographic fashion shows in New York, Hamburg and Beijing; the massive success of ...
The pinhole camera, a technique known since ancient times, has inspired a futuristic technology for lensless, three-dimensional imaging. Working at both the Advanced Light Source (ALS) at the U.S. Department of Energy's Lawrence ...
Researchers at the RIKEN Advanced Science Institute (Japan) have developed a unique way to create full-color holograms with the aid of surface plasmons.
In March of this year, a team of bioengineers from Caltech, JPL, and the University of Washington spent a week in Greenland, using snowmobiles to haul their scientific equipment, waiting out windstorms, and spending hours ...
