The use of nitrous oxide whippets as a recreational drug: Hidden health risks.
(ICP- OES). The particulate matter was also analyzed by scanning transmission electron microscopy (STEM) combined with energy-dispersive X-ray spectroscopy (EDX). The presence of cyclohexyl isothiocyanate ...
Implementation of MALDI-TOF Mass Spectrometry to Identify Fungi From the Indoor Environment as an Added Value to the Classical Morphology-Based Identification Tool
microfungi; yeasts; identification; microscopy; MALDI-TOF MS Abstract: Introduction: During the last decades, molds in the indoor environment have raised concern regarding their potential adverse health ...

Publication Type: Peer reviewed scientific article Authors: Eveline Verleysen; Frederic Brassinne; Frederic Van Steen; Nadia Waegeneers; Karlien Cheyns; Ronny Machiels; Stella Mathioudaki; Isaac Ojea Jimenez; Ledecq, Marina; Jan Mast Source: Food Control, ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
electron microscopy (TEM) was used as a confirmatory technique and served as the basis for bias estimation. The optimisation of the sample preparation step showed that when this protocol was applied to the ...
Unexpected mould diversity in clinical isolates from French Guiana and associated identification difficulties.
assess the impact of this diversity on the accuracy of mold-infection diagnoses, we identified mold clinical isolates in French Guiana during a five-month follow-up using both microscopy and ...
Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.
products by transmission electron microscopy (TEM) and single-particle inductively coupled plasma-mass spectrometry (spICP- MS). TEM analysis showed that all samples contained micrometre-sized flakes and ...
