An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs1−xNx epilayer and in a GaAs single crystal to clarify the ...

NASA researchers identify optimal infrared wavelength for detecting carbon dioxide and methane on exoplanets, guiding the Habitable Worlds Observatory’s design and sensor specifications.

Interstellar comet 3I/ATLAS reached a speed of 58 km/s upon arrival, and was too fast to be captured, making a short flyby a valuable high-value experiment in chemistry, dust physics, and solar ...

Each molecule has its own unmistakable tone – a vibrational “fingerprint” that reflects not only its chemical structure but also the nanoscale environment around it. But the voices of individual ...
