Transmission electron microscopy investigation of networks of pentatwinned silver nanowires has identified the presence of nanoscale defects within individual wires, showing narrow regions of banded contrast normal to the nanowire axis (bamboo faults). Structural analysis using machine learning decomposition of scanning precession electron diffraction data identifies these bamboo faults as a pair...
In this paper, for the first time, a laser direct writing technique is reported to form S‐ and N‐doped graphene patterns on thin (0.3 mm thickness) polyethylene terephthalate (PET) and glass substrates from a specially formulated organic polybenzimidazole (PBI) ink, without thermally affecting the substrates and without the need for a metallic precursor. Unlike standard graphene ink printing, postcuring...
Neuraminidase (NA)-deficient mutant virus stocks have been obtained by passaging A/NWS/33HA-tern/Australia/G70c/75NA(H1N9) influenza virus in medium containing neuraminidase fromMicromonospora viridifaciensand antiserum against the influenza NA. Growth of the resulting mutants is dependent on addition of bacterial neuraminidase to the medium. Nucleotide sequence analysis showed large single deletions...
