Optical high-bitrate nanoantenna developed for use with optical waveguide
(Phys.org)—A team of researchers from several institutions in Germany and Australia has developed an optical high-bitrate nanoantenna that they used with an optical waveguide. In their paper published on the open access site Science Advances, the team explains how their device works and their plans for improving it to make it more commercial.
Here's a tip: Indented cement shows unique properties
Rice University scientists have determined that no matter how large or small a piece of tobermorite is, it will respond to loading forces in precisely the same way. But poking it with a sharp point will change its strength.
Nanoparticles could spur better LEDs, invisibility cloaks
In an advance that could boost the efficiency of LED lighting by 50 percent and even pave the way for invisibility cloaking devices, a team of University of Michigan researchers has developed a new technique that peppers metallic nanoparticles into semiconductors.
Bubble technique used to measure shear forces between graphene sheets
(Phys.org)—A team of researchers from China and the U.S. has devised a relatively simple means for measuring the shear forces that exist between sheets of graphene and other materials. In their paper published in the journal Physical Review Letters, the group describes the technique and the results they found when using it to measure shear […]
NanoVelcro microchips could someday noninvasively diagnose prenatal conditions
Many pregnant women undergo some form of prenatal testing before their children are born. The information that expectant mothers gain from these tests vary, from the baby's gender to genetic defects. But the tests are often invasive, which can potentially harm the fetus and the mother. Now, one group reports in ACS Nano that they […]
Carbon nanotubes turn electrical current into light-matter quasi-particles
Material scientists and physicists from Heidelberg University (Germany) and the University of St Andrews (Scotland) have demonstrated electrical generation of hybrid light-matter particles, so-called exciton-polaritons, by using field-effect transistors with semiconducting carbon nanotubes integrated in optical micro-cavities.
Ultrasensitive DNA quantification by light scattering
Traces of biomolecules such as DNA can be detected with a new "dynamic" technique based on the observation of association and dissociation events of gold nanoparticles. If the desired DNA sequence is present, it can reversibly bind two nanoparticles together. This can be detected in real time through a change in light scattering. As reported […]
Harnessing light to drive chemical reactions
An exotic interaction between light and metal can be harnessed to make chemical reactions more sustainable, but the physics behind it has been widely debated in the field.
Breathable, wearable electronics on skin for long-term health monitoring
A hypoallergenic electronic sensor can be worn on the skin continuously for a week without discomfort, and is so light and thin that users forget they even have it on, says a Japanese group of scientists. The elastic electrode constructed of breathable nanoscale meshes holds promise for the development of noninvasive e-skin devices that can […]
Plasmon-powered devices for medicine, security, solar cells
A Rice University professor's method to "upconvert" light could make solar cells more efficient and disease-targeting nanoparticles more effective.
