p-type NiO nanofibers have been synthesized from a simple electrospinning and sintering procedure. For the first time, p-type nanofibers have been electrospun onto a conductive fluorine doped tin oxide (FTO) surface. The properties of the NiO nanofibers have been directly compared to that of bulk NiO nanopowder. We have observed a p-type photocurrent for a(More)
A simple procedure to develop antibacterial surfaces using thiol-capped gold nanoparticles (AuNPs) is shown, which effectively kill bacteria under dark and light conditions. The effect of AuNP size and concentration on photo-activated antibacterial surfaces is reported and we show significant size effects, as well as bactericidal activity with crystal(More)
The work of our group is focused upon the development of efficient methods for the processing of analog and digital signals over channels of interest. We shall divide the discussion of our work into three areas. 1. Sonar and Oceanographic Research a. Current echo sounders for oceanographic survey ships have a quoted accuracy of 2-3o which implies a(More)
