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 ...

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 ...

Laser lights are usually employed for the Raman spectroscopic analysis. The photons emitted by the laser light are absorbed by the sample, temporarily entering a non-stationary, exceedingly brief ...

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 ...

This article introduces the differences and similarities between Raman and infrared spectroscopy for identifying unknown materials and monitoring reactions. While the techniques are pretty similar, ...

A handheld sensor and innovative technique developed by Texas A&M AgriLife Research scientists could one day offer a noninvasive alternative to food diaries and blood tests when monitoring diet and ...

Raman spectroscopy is a non-destructive investigative method for identifying and distinguishing chemical substances on a microscopic scale. When coupled with chemometric approaches, it forms an ...

Semiconductor nanocrystals are conducting materials with a size that has been reduced to the nanoscale. This size reduction can greatly enhance the physical, chemical, and optical characteristics, ...

New applications of Raman spectroscopy and associated detection schemes are poised to enhance bedside care for patients and tackle a number of current challenges outside medicine. Addressing the SPIE ...

Graphene is a material that has a one-atom layer of carbon atoms with a thickness of only 335 pm. It can be modified using oxidization and functionalization. For example, graphene gains properties ...
