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 ...

Plastic litter has emerged as a pollutant of concern in the oceans around the world over the past few decades. Defined as plastic litter that is smaller than 5 mm, microplastic is thought to be the ...

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 ...

To airport security personnel, an opaque plastic bottle is a dangerous mystery: Does it carry shampoo or explosives? Now researchers have developed a method that uses Raman spectroscopy to detect and ...

"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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
