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 ...

Advances in a range of developmental and analytical tools drive the pharmaceutical industry toward Bioprocessing 4.0. “Adoption of Quality-by-Design (QBD) and Process Analytical Technology (PAT) ...

Hello and welcome to Take Five with Automation. I’m David Miller, Senior Technical Writer for Automation World. The topic of today’s video is going to be something called Raman Spectroscopy. Now, what ...

Microplastics are a growing problem in the world’s oceans, but how do you obtain quick and useful measurements in-situ, and at the depths needed to completely understand distribution, flow, and ocean ...

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 ...

The strength of a Raman signal is inversely proportional to the fourth power of the wavelength of the scattered light. In practical terms, this means that the longer the excitation wavelength used to ...

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 ...

There has been a substantial increase in drug seizures in all major northern European ports, including Rotterdam, Anvers, Dunkerque, and Le Havre. These are now considered one of the main drug ...
