Researchers have developed a method using near infrared hyperspectral imaging and chemometrics to sort different types of plastic and those with varying flame retardants. This technique enables efficient recycling of plastics, reducing the amount dumped into the environment.
Researchers used hyperspectral imaging to analyze a bronze statue by Auguste Rodin, detecting corrosion products brochantite and antlerite. The technique revealed non-uniform distribution of the compounds, which could be missed with traditional sampling methods, providing valuable information for preservation.
Using near infrared chemical imaging can help maintain the safety of pharmaceutical tablets by monitoring active ingredient concentrations in real time. This technique provides a larger sample area compared to spectroscopy, reducing the risk of missed segregation areas.
A novel form of near infrared spectroscopy, known as NIR hyperspectral imaging (HSI), has been developed to detect peanut contamination in powdered foodstuffs. The technique produces images with spectral data at each pixel, allowing it to detect trace levels of peanut over a large area.
Researchers have developed a tiny spray of liquid that forms a merged, femtolitre-size Taylor cone, allowing them to study fast biochemical reactions. The device, called dual nano-electrospray, enables scientists to probe solution interactions and complex biomolecules with unprecedented precision.
Near-infrared (NIR) spectral imaging has been shown to be highly predictive of flap outcome in breast reconstruction, detecting circulatory complications early on. This non-invasive method can provide real-time feedback to surgeons during surgery and post-operative period, improving patient outcomes.
