Cytochrome f (Cyt f) and plastocyanin (Pc) form a highly transient complex as part of the photosynthetic redox chain. The complex from Nostoc sp. PCC 7119 was studied by NMR relaxation spectroscopy with the aim of determining the orientation of Pc relative to Cyt f. Chemical-shift-perturbation analysis showed that the presence of spin labels on the surface(More)
In order to investigate whether the performance of microbolometer based heat imaging devices can be improved by excimer laser annealing, we performed several experiments on amorphous silicon layers. Samples with unstructured and structured amorphous silicon layers, which are fabricated with different doping concentrations using a plasma enhanced chemical(More)
Proper use of a pantograph to program fully adjustable articulators is dependent on stable clutch construction. The technique described uses modeling plastic molded to the labial surfaces of acrylic resin clutches. The labial extensions of the modeling plastic resist lateral movement of the clutches, thereby enhancing clutch retention and stability.
