Optical activity spectroscopy techniques, such as circular dichroism and optical rotatory dispersion, are essential for investigating the chiral properties of molecules and materials. However, current ...

Pythagoras first discovered that the vibrations of strings are drastically enhanced at certain frequencies. This discovery forms the basis of our tone system. Such natural vibrations ubiquitously ...

Oxide–water interfaces are ubiquitous in nature and technological processes, but their characterization is difficult. Now, an in situ nonlinear optical spectroscopy approach enables the ...

“Plasma” refers to a gas with a significant proportion of ionized molecules, which produce various excited ions, atoms, and molecules. Electrons liberated from ions and atoms are highly energetic and ...

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 ...

Figure 1. (a) Schematic diagram of the optical trapping-enhanced SERS optofluidic detection system; (b) effect of the single-beam optical trap module switch state on AgNPs aggregation; (c1) and (c2) ...
