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 ...

Breakthrough in sizing nanoparticles using fluid-filled tubes

Simple mechanical tube key to measuring mass and size of nano-particles simultaneously

31-Aug-2021 - The functionality of nanoparticles in a host of applications, including drug delivery and nano-optics, is often dictated by their mass and size. Measuring these properties simultaneously for the same nanoparticle has also been challenging. Now scientists from the University of Melbourne and ...

Scientists count microscopic particles without microscope

11-Aug-2016 - Scientists from Russia and Australia have put forward a simple new way of counting microscopic particles in optical materials by means of a laser. A light beam passing through such a material splits and forms a characteristic pattern consisting of numerous bright spots on a projection screen. The ...

Jet engines to become cleaner in future

Swiss innovation for measuring particulate emissions from aircraft engines

01-Mar-2016 - Since the 1980s, large aircraft engines have been required to meet emission limits that have been gradually tightened over time. Air traffic, therefore, contributes relatively little to Switzerland's pollution levels, and visible smoke trails in the sky from jet engines are a thing of the past. ...

New precise particle measurement improves subatomic tool for probing mysteries of universe

30-Sep-2015 - Physicists at Southern Methodist University, Dallas, have achieved a new precise measurement of a key subatomic particle, opening the door to better understanding some of the deepest mysteries of our universe. The researchers calculated the new measurement for a critical characteristic of the top ...

Formation of nanoparticles can now be studied molecule-by-molecule

28-Feb-2013 - A study combines the cycles of sulphur, nitrogen and carbon in the ecosystem, as it shows that the molecular clusters need sulphuric acid, amines and oxygenated organics for growth. When the clusters reach a size of 1.5-2 nm, their growth increases considerably. The measurements were conducted at ...

Hot Water in Cold Comets

17-Sep-2010 - Comets, also named “dirty snowballs”, are largely composed of water. An international research team around Andreas Wolf, of the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany, recently succeeded deciphering an important aspect of the way by which water molecules often form in ...
