For the first time, researchers have determined the shape of the actinide nucleus of fermium-255 and measured its structure ...

*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 ...

Together with water, foods supply the main part of the total daily intake of trace elements by humans. In the human diet around the world, vegetables and spices are some of the most common foods. In ...

The AA-7800 Series atomic absorption spectrophotometers have been designed to offer stability and support multielement analysis. The company claims the series also features the industry’s smallest ...

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 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 ...

In 1913, Bohr described the fundamental physical principles on which spectrophotometers are built. He proposed that atoms exist in only a limited number of energy levels, which represent the energy ...

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

X-ray spectroscopic techniques rely on the element-specificity of inner-shell photoexcitation/ionization to probe electronic densities with atomic-site precision. The ...
