Molecular spectrometry measures electromagnetic radiation and materials. Spectrometry can determine a sample's molecular or structural composition in physical and analytical chemistry. Each atom ...

Seeking to create a material that could dynamically change how it interacts with electromagnetic waves, the researchers took inspiration from the chameleon. The sticky-tongued reptile changes ...

Atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

Advances in THz nonlinear optics, which can be used to change the frequency of electromagnetic waves, are essential for the development of high-speed wireless communication and signal processing ...

Chinese astronomers have investigated quasar candidates from the DESI Legacy Surveys (DESI-LS) photometry catalog. As a result, they detected 19 strongly-lensed, dual and projected quasars.

You will be redirected to our submission process. Metamaterials offer unique properties by combining "meta" (beyond) and "material," providing electromagnetic characteristics superior to conventional ...

The FDTD is a computational method based on numerically evaluating the temporal evolution of electromagnetic fields ... Maxwell's equations relate time-dependent changes in the electric (magnetic ...

Deep generative models are rapidly becoming popular for the discovery of new molecules and materials. Such models learn on a large collection of molecular structures and produce novel compounds. In ...

The answer may lie at the other end of the electromagnetic spectrum ... the net effect of a change of current is the emission of radiation, in this case in the terahertz region of the spectrum.

Feb. 12, 2025 — Scientists have uncovered the equipment that enables bacteria to survive exposure to antibiotics: a shuttling mechanism that helps a complex of proteins pump out a wide spectrum ...
