Transfer printed silver nanowire transparent conductors for PbS-ZnO heterojunction quantum dot solar cells.

Transfer-printed silver nanowire transparent conducting electrodes are demonstrated in lead sulfide-zinc oxide quantum dot solar cells. Advantages of using this transparent conductor technology are increased junction surface energy, solution processing, and the potential cost reduction of low temperature processing. Joule heating, device aging, and film thickness effects are investigated to understand shunt pathways created by nanowires protruding perpendicular to the film.

[Carpal dislocation combined with a lunate fracture. Report of a case ].

A fracture of the semi-lunar in the frontal plan seems to be a rare and still exceptional hurt when it accompanies a retro-lunar dislocation of carp. Our case allows to see again the lesionnel mechanism of the dislocations of carp particularly in its retro-lunar variety and so to classify our case or rather to individualize it and to put it there "except series".
