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 ...

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 ...

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 ...

Herein, the O K-edge X-ray absorption spectroscopy (XAS) profile of an aqueous acetonitrile solution presented a distinct sharp peak not commonly observed in the corresponding profile of liquid water.

Ocean Optics reports on how spectroscopy revolutionizes research by utilizing light to analyze materials, improving accuracy ...

What’s the story behind DNA melting temperature analysis? UV-Visible absorption spectroscopy can be used to assess the characteristics of deoxyribonucleic acid (DNA), a naturally occurring polymer ...

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 ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

Charge-carrier traps play a central role in the excited-state dynamics of semiconductor nanocrystals, but their influence is often difficult to measure directly. In CdS and CdSe nanorods of nonuniform ...

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, ...
