Plastic litter has been a key pollutant of concern in the oceans globally over the past few decades. One of the most abundant forms of marine debris is microplastic - defined as plastic litter smaller ...

New technology could remotely identify various types of plastics, offering a valuable tool for future monitoring and analysis of oceanic plastic pollution. A new hyperspectral Raman imaging lidar ...

Raman spectroscopy is a molecular spectroscopy, which is observed as inelastically scattered light and enables the interrogation and identification of vibrational (phonon) states of molecules.

Purdue Research Park instrument maker SpectraCode Inc. has developed a new, cost-effective method to analyze black plastics for recycling purposes. WEST LAFAYETTE, Ind. – Purdue Research Park ...

Recently, a research team led by Prof. GAO Xiaoming from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, improved residual neural network to accurately classify 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 ...

A research team drawn from the Medical University of Vienna and the Research Center for Non-Destructive Testing has developed ...

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 ...

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 ...

"This technology will be of great interest to the plastics community," says Edward Grant, chief executive officer of SpectraCode and Purdue University professor of chemistry. "Being unable to ...
