Physicists have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds of ultracold atoms and to smash them together.
Scientists have managed to create artificial nanostructures that can 'bend light,' called metamaterials. But the challenge has been making enough of the material to turn invisibility cloaks into a practical reality. New work may have just cracked that barrier.
Researchers have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature.
Researchers have revealed similarities between the molecular mechanism of carbon nanotube (CNT) growth and hydrocarbon combustion. The study identifies new ways to control the growth of CNTs and increase the understanding of fuel combustion processes.
An international team of researchers found that a nanoparticle trapped with laser light temporarily violates the famous second law of thermodynamics, something that is impossible on human time and length scale.
By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer. The material can operate at up to 200 degrees Celsius.
New reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings may lead to better designs and improved performance in organic solar cells.
Scientists at the Center for Nanotechnology and Nanotoxicology at Harvard School of Public Health have discovered a fast, simple, and inexpensive method to measure the effective density of engineered nanoparticles in physiological fluids, thereby making it possible to accurately determine the amount of nanomaterials that come into contact with cells and tissue in culture.
A new analysis accurately describes the behavior of silicon photon microresonators in the nonlinear regime, where the amount of light exiting the system is not directly proportional to the amount of light entering it.
Latest research finds that the trailblazing perovskite material used in solar cells can double up as a laser, strongly suggesting the astonishing efficiency levels already achieved in these cells is only part of the journey.
