Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising isolated ...

Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...

Though the sun produces more energy than we would ever need on Earth, current ...

Absorption spectroscopy is an analytical chemistry tool that can determine if a particular substance is present in a sample by measuring the intensity of the light absorbed as a function of wavelength ...

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

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 ...
