Activation of hematite nanorod arrays for photoelectrochemical water splitting

Morrish, Rachel ; Rahman, Mahfujur ; MacElroy, J. M. Don ; Wolden, Colin Andrew (Wiley, 2011-04-18)

Hematite nanorod arrays were activated through proper control of annealing conditions. The 100-fold improvement in photocurrent was correlated with increased absorption and Sn doping from the tin oxide coated glass ...
Centimetre scale assembly of vertically aligned and close packed semiconductor nanorods from solution

Ahmed, S. ; Ryan, Kevin M. (RSC publications, 2009-09-08)

Assembly of CdS nanorods (8 × 100 nm) into vertically aligned arrays over very large areas on a substrate either as a monolayer or several multilayers is shown by electrophoresis.
Directing semiconductor nanorod assembly into 1D or 2D supercrystals by altering the surface charge

Singh, Ajay ; Gunning, Robert Denis ; Sanyal, Amberish ; Ryan, Kevin M. (RSC publications, 2010)

Coulomb repulsion due to the surface charge on semi-conductor nanorods works against the dipole–dipole attraction that tends to direct the nanorods to self-assemble; the nature of this self-assembly for CdSe nanorods can ...
Spontaneous room temperature elongation of CdS and Ag2S nanorods via oriented attachment

O'Sullivan, Catriona ; Gunning, Robert Denis ; Sanyal, Ambarish ; Barrett, Christopher A. ; Geaney, Hugh ; Laffir, Fathima R. ; Ahmed, Shafaat ; Ryan, Kevin M. (ACS Publications, 2009-08-06)

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 ...
