An integrated model of impurity migration and wall composition dynamics for tokamaks
TL;DR: In this paper, a model was developed that describes the coupling of local erosion to the global impurity transport and re-deposition processes in a self-consistent way, where the erosion and deposition on each surface element of first wall is described by an ordinary differential equation (ODE).

Influence of doping (Ti, V, Zr, W) and annealing on the sp2 carbon structure of amorphous carbon films
TL;DR: In this article, the influence of the transition metal doping on the carbon matrix nanostructuring during the thin film growth and subsequent annealing is investigated, and the existence of graphenelike regions in a-C is concluded from a (10) diffraction peak.
