  • Singh, Ajay; Gunning, Robert D.; Ahmed, Shafaat; Barrett, Christopher A.; English, Niall J.; Garate, José-Antonio; Ryan, Kevin M. (Royal Society of Chemistry, 2012)
    Spontaneous supercrystal organisation of semiconductor nanorods (CdS and CdSe) of different aspect ratios into ordered superstructures was obtained by controlled evaporation of a nanorod solution. The rods either align ...
  • Ahmed, Shafaat; Ryan, Kevin M. (American Chemical Society, 2007)
    Supercrystallisation of CdS nanorods (10 nm × 25 nm) into perpendicular superlattices was obtained by controlled evaporation of a nanorod solution trapped between a smooth substrate and a block of highly ordered pyrolytic ...
  • O'Sullivan, Catriona; Gunning, Robert D.; Sanyal, Ambarish; Barrett, Christopher A.; Geaney, Hugh; Laffir, Fathima R.; Ahmed, Shafaat; Ryan, Kevin M. (American Chemical Society, 2009)
    Spontaneous elongation from nanorod to nanowire in the presence of an amine is reported for nanocrystals of cadmium sulfide and silver sulfide (cation exchanged from CdS). Elongation occurs instantaneously where the final ...
