Advanced Raman filters can be employed in Raman spectroscopy to deliver immediate data on biological tissue. These filters have great potential in research, medicine, and biomedical engineering and ...

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 ...

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, ...

Process analytical technology (PAT), a quality assurance program for the pharmaceutical industry developed by the US Food and Drug Administration, enables pharmaceutical manufacturers to control ...

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 ...
