In recent years, microplastics have emerged as a significant concern for environmental health and safety, with their long-term impacts still not fully understood. Defined as plastic particles smaller ...

The prototype hyperspectral Raman imaging lidar system included a pulsed 532- nm green laser and a 2D imaging spectrometer with a gated ICCD. WASHINGTON — Researchers have developed a new ...

Microplastics have recently gained significant scientific and political attention and are now regarded as a critical environmental and health concern. This has led to a surge in research on ...

Edward Grant, a Purdue University professor of chemistry, demonstrates new technology developed by SpectraCode, the company he formed at the Purdue Research Park. With distributed focusing, ...

We don’t often think of plastics as having “fingerprints.” But they do. And, as we continue to find microparticles in unexpected places — from local anchovy and seabird guts to the deepest trenches of ...

Black plastics pose an identification problem for sorting machines at recycling facilities, as the sensors can't see them. Canon has developed a system that users lasers and tracking tech to identify ...

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 ...
