Researchers at the University of Maryland have engineered a new fabric from synthetic yarn with a carbon nanotube coating that is activated by temperature and humidity, releasing heat in warm humid conditions and trapping heat when conditions are cool and dry.
Constant question: nanolaser or just simple LED? Physicists from MIPT have developed a method that will help you to find at what circumstances nanolasers qualify as true lasers bypassing technically challenging direct coherence measurements.
A new physical effect has been demonstrated at the University of Bath after 40 years of pursuit by physicists around the world, which could lead to advancements in chemical manufacturing efficiency, miniaturization and quality control in personalized pharmaceuticals.
Laser physicists have succeeded in reducing the acquisition time for data required for reliable characterization of multidimensional electron motions by a factor of 1000.
An international team of researchers from Aalto University and Université Paris-Sud has significantly improved the propagation of data inside a microchip.
For the first time, researchers have shown that the non-conventional imaging method known as ghost imaging can be performed using a low-cost, chip-based light-illuminating device.
In work that provides insights for several areas of wave physics -- Maxwell electromagnetism, topological quantum states, and plasmonics/metamaterials -- scientists showed that the well-known surface electromagnetic waves at interfaces between homogeneous isotropic media, obtained within classical Maxwell's electromagnetism, also have a purely topological origin, similar to quantum topological states.
By bombarding an ultrathin semiconductor sandwich with powerful laser pulses, physicists at the University of California, Riverside, have created the first 'electron liquid' at room temperature. The achievement opens a pathway for development of the first practical and efficient devices to generate and detect light at terahertz wavelengths -- between infrared light and microwaves. Such devices could be used in applications as diverse as communications in outer space, cancer detection, and scanning for concealed weapons.
Researchers at the Paul Scherrer Institute PSI have developed a new method that makes X-ray images even better: The resolution is higher and allows more precise inferences about the properties of materials. They moved the lens of an X-ray microscope and recorded a number of individual images to generate, with the help of computer algorithms, the actual picture. They have, for the first time ever, transferred the principle of so-called Fourier ptychography to X-ray measurements.
Aspirin is not only an important drug but also an interesting physics model system in which molecular vibrations and electrons are coupled in a particular way. For the first time, X-ray experiments in the ultrashort time domain make electron motions visible in real time. They demonstrate that very small atomic displacements shift electrons over much larger distances within the aspirin molecules.
