Prospects for pilot plants based on the tokamak, spherical tokamak and stellarator

“…Possible ways to increase the effective inboard TF current density include [20] • Alternative structural concepts, for example bucking versus wedging. Preliminary estimates indicate that the combined effects of these improvements could increase the effective TF current density by a factor up to 1.5 [21] (i.e. up to 18 MA m −2 ) approaching the values considered here for compact AT and CS pilot plants.…”

Hydrolysis of (trimethylamine)borane with ion-exchange resins: effect of ionic surfactants

“…Since the 1940s, an enormous amount of research has been devoted to studies of polymer-surfactant systems in aqueous solutions.1 Much less work has been carried out on polymersurfactant interactions in nonaqueous media, mainly due to the great difficulty of taking into account all the interactive forces in these systems.2•3 However, this more complex situation is of particular interest when one considers the processes involving ion-exchange materials, such as phase-transfer catalysis with ionexchange resins4 or reactive extraction with ion-exchange membranes. [5][6][7] In preceding papers from this laboratory,6•8 we demonstrated a novel D-H exchange reaction on (trimethylamine)borane (TB) occurring at the interface between the waterswollen ion-exchange resin or membrane and the organic phase.…”
