Comprehenisive characterization of molecular interactions based on nanomechanics
(2008)
Molecular interaction is a key concept in our understanding of the biological mechanisms of life. Two physical properties change when one molecular partner binds to another. Firstly, the masses combine and secondly, the ...
Effect of Catalyst Diameter on Vapour-Liquid-Solid Growth of GaAs Nanowires
(2014)
GaAs nanowires were grown on (111)B GaAs substrates using the vapour-liquid-solid mechanism. The Au/Pt nanodots used to catalyse wire growth were defined lithographically and had varying diameter and separation. An in-depth ...
Rearrangement and elimination of ordered surface layers of crystalline bubble structures due to gas diffusion
(2009)
We describe a hitherto unknown self-organising effect in wet crystalline bubble structures exposed to air. Due to the escape of gas from the bubbles in the top surface layer, bubbles shrink and create space for the bubbles ...
Understanding DNA dispersed single-walled carbon nanotube systems
(Trinity College (Dublin, Ireland). School of Physics, 2008)
HiPCO Single-walled carbon nanotubes (SWNTs) have been dispersed in
water using a variety of different nucleic acids. An extensive study of the factors
controlling the quality of the DNA-SWNT dispersions was carried out, ...
Nitrogen-doped pyrolytic carbon films as highly electrochemically active electrodes.
(2013)
Nitrogen-doped Pyrolytic Carbon (N-PyC) films were employed as an electrode material in electrochemical
applications. PyC was grown by
via
non-catalysed chemical vapour deposition and subsequently
functionalised
via
exposure ...
Effect of metal nanoparticle concentration on localized surface plasmon mediated Förster resonant energy transfer
(2012)
The influence of gold nanoparticle concentration on signatures of localized surface plasmon mediated Förster resonant energy transfer is investigated in a quantum dot–gold nanoparticle sandwich structure. At lower gold ...
Origin of the half-metallic properties of graphitic carbon nitride in bulk and confined forms
(2013)
The electronic and magnetic properties of graphitic carbon nitride (g-C4N3) in both its bulk and confined form are investigated by using density functional theory. Our calculations show that the 2pz orbital of the carbon ...
Spin valves and their application
(Trinity College (Dublin, Ireland). School of Physics, 2006)
The discovery of giant magnetoresistance (GMR) in the late 1980's resulted in massive
interest in the deposition and characterisation of artificial layered magnetic structures.
Spin valves were discovered in 1991 and have ...
Thermometry by correlated dephasing of impurities in a one-dimensional Fermi gas
(2024)
We theoretically investigate the pure dephasing dynamics of two static impurity qubits embedded within a
common environment of ultracold fermionic atoms, which are confined to one spatial dimension. Our goal is
to ...
Influence of growth conditions on magnetite nanoparticles electro-crystallized in the presence of organic molecules.
(2013)
Magnetite nanoparticles were synthesi
zed by electrocryst
allization in the
presence of thiourea or sodium butanoate as
an organic stabiliz
er. The synthesis was
performed in a thermostatic electrochemical
cell ...
