During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

Raman spectroscopy is increasingly used for polymer characterization because it is non-destructive, requires no sample preparation, and produces data in seconds. It is also simple for the user; even ...

Visualization of Tip-Enhanced Raman Spectroscopy (TERS): This diagram illustrates the interaction of a laser beam with a sample surface through a sharp metallic tip. The red laser light excites the ...

Graphene is a two-dimensional, one-atom-thick hexagonally organized material composed of sp2 carbon networks with strong covalent bonds. As graphene absorbs only 2.3 percent of incident light, it is ...

Lithium-ion batteries (LIB) have been of significant interest for many years, offering a rechargeable alternative to lithium batteries. These batteries are widely employed in various portable ...

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength ...

Since its discovery in 2004, graphene has become a highly prized material in electronics applications owing to its unusual electronic structure. 1 Although graphene is only composed of carbon atoms, ...

The war on drugs shows no indication of slowing down; illicit drugs appear on the market every day, and law enforcement officers face numerous challenges in their endeavors to reduce trafficking and ...
