Jan. 11, 2022 Researchers have now succeeded in producing an extremely simple and compact source of terahertz radiation: An oscillator with double resonant-tunneling diodes. Its radiation power significantly ...
Aug. 4, 2021 X-ray imaging is a fast and painless way for doctors to see inside a person. But radiation detectors, which go under the body part being imaged, are rigid panels that contain harmful heavy metals, ...
Feb. 16, 2022 Physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, ...
Dec. 19, 2023 Researchers all over Germany have developed a new system for X-ray imaging, which is suited for both living specimens and sensitive materials. The system records images of micrometer resolution at a ...
June 1, 2022 Using NASA's SOFIA observatory and other data resources, an international team of astronomers has uncovered evidence of metals in local galaxies -- found to be deficient in earlier studies -- by ...
Nov. 10, 2021 Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology. The researchers measured the spontaneous emission of fast ...
Apr. 7, 2022 Researchers have captured images of multiple radionuclides in mice using astronomy ...
Mar. 18, 2024 Important data can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists show. Holography can be done quite easily: A 3D printer can be used ...
Mar. 14, 2024 Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers ...
Jan. 18, 2023 Intense, extremely short-wave X-ray pulses in the nanometer wavelength range are difficult to produce, but now a new, simpler method has been developed: the starting point is not a titanium-sapphire ...
