A clock built from thorium-229 has crossed an important line, from a long-discussed concept to a working device. The shift ...

*If you learn how to use atomic absorption spectroscopy (AAS), you can do accurate and reliable chemical research. But it takes practice and concentration to fully grasp its basic ideas. Understanding ...

A method to interpret artificial intelligence (AI) models used in materials discovery by analyzing their learned features has been developed by researchers from Japan. The method extracts key features ...

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 ...

What is Atomic Absorption Spectrometry? AAS is a technique for determining how much of a specific element is present in the specimen under study. The uptake of optical radiation by neutral atoms in ...

X-ray absorption spectroscopy (XAS) measures the transmission of a substance as a function of the incident photon energy E in the X-ray regime. It is element-specific and orbital-specific, enabling ...

Graph neural networks are attractive for learning properties of atomic structures thanks to their intuitive graph encoding of atoms and bonds. However, conventional encoding does not include angular ...

Can you briefly explain what transient absorption (TA) spectroscopy is and why it is important? Transient absorption (TA) spectroscopy is a pump-and-probe technique used to study the absorption of ...
