Scientists could have a new way to explore the hidden behavior of matter, thanks to research involving Queen Mary University ...

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 ...

X-Ray Absorption Spectroscopy (XAS) is a powerful technique for probing the local electronic and geometric structure of matter with element and site specificity. By measuring the absorption of X-rays ...

For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and ...

Flame Atomic Absorption Spectroscopy (FAAS) is a very popular analytical technique that has been employed by researchers for the elemental analysis of trace metals in a variety of samples. How does it ...

Researchers led by Prof. ZHOU Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom ...

Scanning Tunneling Microscopes (STMs) are amazing tools which can manipulate singular atoms, but they cannot characterize these atoms as they act only on the outer electron shell. Meanwhile X-ray ...

The spectrum of a substance — how it interacts with light — provides fundamental insight into its composition. A large number of molecules is typically required to obtain a detectable light-absorption ...

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 ...

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 ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...
