Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

Nonthermal and thermal plasmas are used in the industrial, engineering, medical, and research industries. Plasma composition is an important parameter in any plasma process. Using optical emission ...

Although carbon emissions from fossil fuels dominate headlines, toxins like sulfur oxides (SO x) and nitrogen oxides (NO x) have a significant impact on air quality and human health. Avantes invites ...

“Plasma” refers to a gas with a significant proportion of ionized molecules, which produce various excited ions, atoms, and molecules. Electrons liberated from ions and atoms are highly energetic and ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for efficient hydrogen conversion, surpassing conventional photocatalysts.

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...
