Due to increasing environmental pollutants and global industrialization, food and water safety have become crucial concerns today. Ensuring that consumables are free from harmful contaminants is a ...

*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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy are two techniques used to study atomic structures. The main difference between these tools is that X-ray crystallography uses X ...

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, ...
