Protocol exchange (2022) Keywords: Acid digestion Face mask microwave Nanoparticles nonwoven textile Abstract: We present herein a digestion method based on high-temperature (260 °C) microwave heating and ...
IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
fibre-grade TiO2 particles. Because there are no methods available for measuring exposure directly, the methodology that ANSES applied to determine the professional exposure limits to titanium dioxide in its ...
METROFOOD-RI: Pilot services with physical, remote and virtual access
mainly addressed to researchers, laboratories, food inspection agencies and policy makers: a search engine and database for agrifood reference materials and official methods an application programming ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
study was set up to determine the size of environmentally relevant FeOx colloids with new methods, i.e. Flow Field Flow Fractionation (FlFFF- UV- ICP- MS) and single-particle ICP- MS / MS (sp- ICP- MS) ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
approach on the certified reference materials ERM- FD100 and ERM- FD304. The image analysis method was validated in an inter-laboratory study by 19 laboratories, which resulted in a within-laboratory ...

Multivalent binding of herpesvirus to living cells is tightly regulated during infection.
introduce a new method to force-probe multivalent attachment directly on living cells, and we show, for the first time, direct evidence of a new mechanism by which a herpesvirus surface glycoprotein acts as ...
