*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 ...

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 ...

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 ...

Atomic force microscopy (AFM) and infrared (IR) spectroscopy have emerged as complementary techniques that enable the precise characterisation of materials at the nanoscale. AFM provides ...

LLNL scientist Tuan Anh Pham and colleagues used machine learning and X-ray spectroscopy to predict structure and chemical composition of heterogeneous materials. Credit: Blaise Douros / LLNL Lawrence ...

Researchers have observed hydrogen and deuterium molecules in tiny spaces called picocavities using advanced spectroscopy. This study reveals unique differences between the molecules due to quantum ...
