Identifying and quantifying nanoparticles in powder materials is a time-consuming and expensive task, but it is also important. Currently, electron microscopy imaging techniques are primarily used to count and measure the dimensions of thousands of individual particles. This allows us to determine what percentage (by number) of the particles are nanoparticles. However, this is only a relative nanoparticle content and is therefore limited in the answers it can provide. We present the new PowMaste...

Created in the 1970s, dynamic light scattering (DLS) has established itself over the years as an essential technique for measuring the size distribution of nanoparticles suspended in liquids. Indeed, thanks to its precision and ease of use, DLS is become now a reference method for characterizing colloids in scientific and industrial applications.  In this webinar, after a review of the basic principles of DLS, we will present recent technological advances in this technique, in particular th...

Nanomaterials are a fantastic source of innovation and are used in many industrial sectors. However, their use may be limited by a lack of accessibility, validation or harmonization of methods for characterizing their key physico-chemical properties, as required by current regulations (R-Nano, REACh). To meet these challenges, the NanoMesureFrance association was created in September 2022 through a public-private partnership between LNE, FEBEA and France Chimie. This structure aims to boost conf...

Les nanomatériaux constituent de formidables sources d’innovation et irriguent de nombreux secteurs industriels. Leur utilisation peut néanmoins être limitée par un manque d’accessibilité, de validation ou d’harmonisation des méthodes de caractérisation de leurs propriétés physico-chimiques clés telles que demandées par les réglementations en vigueur (R-Nano, REACh). Afin de répondre à ces enjeux l’association NanoMesureFrance a été créée en Septembre 2022 à travers un...
