Repairing Nanoparticle Surface Defects
Solar devices based on semiconductor nanoparticles require the use of conductive ligands; however, replacing the native, insulating ligands with conductive metal chalcogenide complexes introduces structural defects within the crystalline nanostructure that act as traps for charge carriers. We utilized atomically thin semiconductor nanoplatelets as a convenient platform for studying, both micros...
متن کاملRepairing a torn cell surface
Since the advent of microsurgical techniques in the early part of the last century, it has been known that animal cells can survive the experimental creation of very large holes (>1000 μm2) in their surface (reviewed in Chambers and Chambers, 1961; Heilbrunn, 1956). Remarkably, these initial observations of a truly remarkable cell capacity failed, for many subsequent decades, to generate furthe...
متن کاملUse of chitosan scaffolds for repairing rat sciatic nerve defects.
Neurotmesis must be surgically treated by direct end-to-end suture of the two nerve stumps or by a nerve graft harvested from elsewhere in the body in case of tissue loss. To avoid secondary damage due to harvesting of the nerve graft, a tube-guide can be used to bridge the nerve gap. Previously, our group developed and tested hybrid chitosan membranes for peripheral nerve tubulization and show...
متن کاملRepairing Osteochondral Defects of Critical Size Using Multiple Costal Grafts
OBJECTIVE To investigate the feasibility of repairing osteochondral defects of critical size by performing mosaicplasty using multiple sliced costal cartilage grafts, which enables repair of extensively injured knees using grafts from a single rib. DESIGN Critical osteochondral defects were prepared on the femoral groove of skeletally mature Japanese white rabbits. Costal cartilage grafts fro...
متن کاملNanoparticle Near-Surface Electric Field.
Theoretical studies show that surface reconstruction in some crystals involves splitting the surface atomic layer into two-upper and lower-sublayers consisting of atoms with only positive or only negative effective electric charges, respectively. In a macroscopic crystal with an almost infinite surface, the electric field induced by such a surface-dipole is practically totally concentrated betw...
