*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 ...

Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited ...

Fossil fuels are widely used in automobiles, industry, and power plants, but due to excessive use they are depleting at a rapid rate. This has prompted a search for renewable, sustainable, and ...

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 ...

Milk is one of the fundamental food groups in the human diet, both as various dairy products and in its original state. The 2008 Chinese contaminated baby formula scandal increased awareness amongst ...

THE three Cantor lectures on the above subject, delivered by Prof. H. Dingle to the Royal Society of Arts in November and December 1934, have now been published (London: Royal Society of Arts, 1935.

Analytical spectrometry encompasses a diverse range of techniques that measure the interaction of electromagnetic radiation with matter, providing both qualitative “fingerprints” and quantitative ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
