Evaluation of the types, efficient use and health risks of application of silver-based biocides to provide antimicrobial properties to face masks applied during the Covid-19 crisis
biocides in face masks using electron microscopy and EDX, combined with total silver measurement using ICP- MS or ICP- OES demonstrated the presence of varying amounts and different types of silver-based ...
Identification and characterization of TiO2 nanoparticles in face masks by TEM
(nano)particles inside the cross section of the textile fibres by scanning TEM (STEM) combined with energy dispersive X-ray spectroscopy (EDX), (iii) measurement of the number-based particle size distribution based ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
By combining optimized sample preparation with method validation, a significant variation in the particle size and shape distributions, the crystallographic structure (rutile versus anatase), and the ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
in E174 itself. The E174 food additives showed a large silver background concentration combined with a relatively low number of nanoparticles, making data interpretation more challenging than in the ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
Source: Materials (Basel), Volume 12, Issue 14 (2019) Abstract: An approach for the size measurement of particulate (nano)materials by transmission electron microscopy was evaluated. The approach combines ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
material Abstract: An approach for the size measurement of particulate (nano)materials by transmission electron microscopy was evaluated. The approach combines standard operating procedures for specimen ...
Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution
agents (alumina, sodium or potassium in combination with phosphate). Particle size analyses, by TEM, SEM, XDC or DC, have been carried out on five commercial brands of anatase E 171 and one of rutile E 171 ...
Combining TEM with single particle ICP-MS: assessing the size of individual nanoparticles in food additives by multiple techniques
Publication Type: Scientific poster, presentation or proceeding Authors: Nadia Waegeneers; Delfosse,L.; Sandra De Vos; Eveline Verleysen; Jan Mast Source: Workshop: Physicochemical characterisation of nano-sized particles in food, Sciensano, Issue Sciensa ...
