MOOLs for MOOCs: A first edX scalable implementation [PDF]

2016 13th International Conference on Remote Engineering and Virtual Instrumentation (REV), 2016
Deploying remote laboratories at a large scale is the next challenge in remote experimentation. It is referred as Massive Open Online Labs (MOOLs). Being able to sustain a massive number of users accessing a specific resource concurrently is a complex task. This paper presents technical solutions, currently deployed, to implement such a remote lab in a

Towards Quantitative EDX Results in 3 Dimensions [PDF]

Microscopy and Microanalysis, 2014
In principle, energy dispersive X-ray (EDX) mapping can be combined with electron tomography since the number of generated X-rays scales linearly with sample thickness. However, early attempts to perform 3D EDX experiments were complicated by the specimen-detector geometry [5]. Therefore, recent efforts lead to a novel design of the EDX detector system,

EDX-analysis of fluoride precipitation on human enamel [PDF]

Scientific Reports, 2019
AbstractOne mechanism of action for the anticaries effect of topical fluoridation is through precipitation of CaF2. In this in vitro study energy-dispersive x-ray spectroscopy (EDX) is used as a semiquantitative method to detect enamel fluoride-precipitation under the influence of acidic and neutral pH-value and absence or presence of a salivary ...
