PFAS analysis: Reliably detecting eternity chemicals

analytica conference: PFAS in the focus of science

27-Feb-2024 - Perfluorinated and polyfluorinated alkyl substances (PFAS) are colloquially known as “eternity chemicals” due to their persistence in the environment. PFAS do not occur naturally, but they can be found in all sorts of things from food packaging and outdoor textiles to seals and hoses. This group ...

Quantum sensors make microscale NMR spectroscopy possible

23-Oct-2023 - The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research ...

Benchtop NMR spectroscopy can accurately analyse pyrolysis oils

More accessible analysis could help develop the potential of bio-oils as an alternative to fossil fuels

12-Sep-2023 - A team of researchers at Aston University has demonstrated that benchtop spectrometers are capable of analysing pyrolysis bio-oils just as well as far more expensive, high-field spectrometers. Bio-oils resulting from the intense heating (pyrolysis) of industrial or agricultural by-products, are ...

How Spheres Become Worms: Breakthrough with NMR spectroscopy

A previously unknown form of hydrogel formation has been elucidated: chemists found unusual interactions between polymers

02-May-2023 - Hydrogels? Many people use these substances without knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot of liquid. In the process, the initially dry material becomes Jelly-like, but it does not wet. Some people place the swellable material on their eyeballs – soft ...

Exposing what’s in tattoo ink

Ingredient lists often aren’t accurate

29-Aug-2022 - From life-like faces to elaborate nature scenes, tattoos are a true art form. Although people have decorated their bodies for millennia for ceremonial and religious reasons, many people today adorn themselves with these images as a form of self-expression. But the inks used for tattoos are ...
