ETUDE DE LA PERSISTANCE DE LA COUCHE DE HOSPHATE DE SODIUM

Mass Spectrometry (ToF-SIMS) and its Application to Materials Science Sarah Fearn Chapter 1 Introduction For the last 50 years, secondary ion mass spectrometry (SIMS) has been at the forefront of high-resolution materials analysis and characterisation A combination of factors makes SIMS unique amongst the analytical techniques widely available: it

Application of imaging TOF-SIMS in cell and tissue research

This thesis is aimed at extending the use of TOF-SIMS (time of flight secondary ion mass spectrometry) as an analytical tool in cell and tissue research TOF-SIMS is a relatively new method that allows analysis of the chemical composition of sample surfaces Originally, it was

Chemical analysis of surfaces and organic thin films by means

Application note of ToF-SIMS – Grafting of styrene and maleic anhydride on polyolefin surfaces – There are polystyrene sequences [Sty-Sty-Sty] ? There are maleic anhydride sequences [MSA-MSA-MSA] ? There are hydrolyzed maleic anhydride groups? CH 2 CH O O O H H CH 2 CH + monomers, + initiator 160 180 200 m/z [amu] 147
