Photonics-based wireless link breaks speed records for data transmission

Thu, 02/01/2024 - 9:18am
Researchers demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.

Physicists develop highly robust time crystal

Thu, 02/01/2024 - 9:18am
Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.

Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators

Thu, 02/01/2024 - 9:18am
Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.

Short X-ray pulses reveal the source of light-induced ferroelectricity in SrTiO3

Thu, 02/01/2024 - 9:18am
Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.

Intensifying the production of high-value compounds from industrial waste

Thu, 02/01/2024 - 9:17am
New research demonstrates how glycerol carbonate, a biosourced industrial additive, can be produced in record time using CO2 and a by-product of the cooking oil recycling industry. The process relies on a hybrid approach combining fundamental physical organic chemistry and applied flow process technology. Two industrial wastes are thus converted into glycerol carbonate, a biosourced rising star with high added-value.

Engineers unmask nanoplastics in oceans for the first time, revealing their true shapes and chemistry

Thu, 02/01/2024 - 9:17am
Millions of tons of plastic waste enter the oceans each year. The sun's ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems. In a new study, engineers have presented clear images of nanoplastics in ocean water off the coasts of China, South Korea and the United States, and in the Gulf of Mexico. These tiny plastic particles, which originated from such consumer products as water bottles, food packaging and clothing, were found to have surprising diversity in shape and chemical composition.

Engineers develop hack to make automotive radar 'hallucinate'

Wed, 01/31/2024 - 3:35pm
Engineers have demonstrated a system they've dubbed 'MadRadar' for fooling automotive radar sensors into believing almost anything is possible. The technology can hide the approach of an existing car, create a phantom car where none exists or even trick the radar into thinking a real car has quickly deviated from its actual course. And it can achieve this feat in the blink of an eye without having any prior knowledge about the specific settings of the victim's radar, making it the most troublesome threat to radar security to date.

Tracking unconventional superconductivity

Wed, 01/31/2024 - 11:44am
At low enough temperatures, certain metals lose their electrical resistance and they conduct electricity without loss. This effect of superconductivity is known for more than hundred years and is well understood for so-called conventional superconductors. More recent, however, are unconventional superconductors, for which it is unclear yet how they work.
