Measuring particle size distribution during the grinding process

A further step toward a stable measurement method for nanoparticles used in industry

26-Jul-2024 - How pharmaceuticals act, how efficient catalysts are and how effective and accurate printing inks function all depend on the size of the nanoparticles they contain. However, there are as of yet no methods for monitoring the particle size distribution during grinding processes. In the EU-funded ...

Highest precision: Microstructured fiber measures the size of nanoparticles

Better research into environmental and bioanalytical issues in the future

08-Dec-2022 - Researchers at Leibniz Institute of Photonic Technology (Leibniz IPHT) developed a new glass fiber design that enables exceptionally long observations of a large number of individual, freely moving nanoparticles in a liquid. This allows the size distribution of nano-objects in a sample to be ...

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 ...
