Controlling the resistive switching hysteresis in VO2 thin films via application of pulsed voltage
(2020)
We investigate the origin of the variation in resistive switching hysteresis of VO2 thin films. Using pulsed electrical measurements in textured VO2 thin film devices, we show that the hysteresis observed in I–V curves ...
Hydrogen evolution across nano-Schottky junctions at carbon supported MoS 2 catalysts in biphasic liquid systems
(2012)
The activities of a series of MoS 2-based hydrogen evolution catalysts were studied by biphasic reactions monitored by UV/Vis spectroscopy. Carbon supported MoS 2 catalysts performed best due to an abundance of catalytic ...
Coupled cavity modes in photonic molecules with semiconductor nanocrystals
(2005)
We present a detailed study of the localized coupled-cavity modes in a photonic molecule formed from two dielectric
spherical microcavities with CdTe nanocrystals, which show a multi-peak narrowband modal structure resulting ...
Synthesis and properties of a novel carbon nanotube-polymer thin film composite
(Trinity College (Dublin, Ireland). School of Physics, 2006)
A novel method for carbon nanotube-polymer composite production is demonstrated in this thesis. The technique presented provides a way in which the position of nanotubes within a polymer matrix can be controlled. By ...
Time for a rethink of research proposal evaluation?
(2007)
The processes of research proposals and evaluation have become ever more elaborate, but the system remains primitive. This paper argues for a fresh look at existing practices, with a view to developing less onerous and ...
Flexible, transparent dielectric capacitors with nanostructured electrodes
(2012)
We have prepared flexible, transparent, dielectric capacitors by spraycasting very thin networks of single walled nanotubes (SWNTs) or silver nanowires (AgNWs) onto either side of free-standing polymer films. Impedance ...
Optical investigations of the magnetic properties of iron nanostructures grown on tungsten(110)
(Trinity College (Dublin, Ireland). School of Physics, 2007)
The structural and magnetic properties of ultra-thin Fe films and Fe nanostripes grown
on vicinal W(110) are studied using Reflectance Anisotropy Spectroscopy (RAS), and
the non-linear optic techniques of Second Harmonic ...
Magnetic properties of iron-rich Fe-Zr glasses
(American Physcial Society, 1987)
A systematic study of the magnetic properties of melt-spun amorphous FexZr100-x alloys with 88?x?93 using Mossbauer and magnetization measurements has established the magnetic phase diagram. The ordering temperature Tc ...
Dispersion and characterisation of carbon nanotube and MoSI nanowire composites
(Trinity College (Dublin, Ireland). School of Physics, 2007)
Recently, composites of polymers with various one-dimensional nanoparticles,
mainly carbon nanotubes, have been investigated to develop robust electrically and
thermally conductive materials or for mechanical reinforcement. ...
