Development of transparent, conducting composites by surface infiltration of nanotubes into commercial polymer films
(2009)
Here we present a novel technique for the preparation of thin, transparent and conducting, nanotube containing layers at the surface of commercially available polyethylene films. This is achieved by the swelling of the ...
Structure and energy of liquid foams
(2015)
We present an overview of recent advances in the understanding of foam structure and energy and their depen-
dence on liquid volume fraction. We consider liquid foams in equilibrium for which the relevant energy is ...
The thermal properties of solar flares over three solar cycles using GOES X-ray observations
(2012)
Solar flare X-ray emission results from rapidly increasing temperatures and emission measures in flaring active region loops. To date, observations from the X-Ray Sensor (XRS) onboard the Geo- stationary Operational ...
Properties of massive stars before death
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)
Despite their importance, there is a lot yet to be learned regarding massive stars,
particularly those at late evolutionary stages. In the first of two studies presented
here, we investigate a suspected very massive star ...
Oxygen-induced p(3 x 1) reconstruction of the W(100) surface
(2005)
The oxidation of the W(100) surface at elevated temperatures has been studied using room temperature STM and LEED. High exposure of the clean surface to O-2 at 1500 K followed by flash-annealing to 2300 K in UHV results ...
Magnetic barcodes in molecular medicine
(Trinity College (Dublin, Ireland). School of Physics, 2010)
The need for faster and more sensitive diagnostic systems for the early detection of many
life-threatening diseases is the driving force behind the work in this thesis. A lab-on-a-chip
prototype device incorporating a ...
Improved Solar Thermal Technology For Decarbonising Residential Heating
(2023)
The field of solar energy harvesting has emerged over the last number of years as one with considerable scope to provide clean and renewable electricity and heat. Solar Thermal (ST) technology is vital to tackle the pressing ...
Thermodynamics of precision in quantum nonequilibrium steady states
(2019)
Autonomous engines operating at the nanoscale can be prone to deleterious fluctuations in the heat and particle currents. Thermodynamic uncertainty relations (TURs) express a fundamental lower bound which translates a ...
Bias-dependent oscillatory electron transport of monatomic sulfur chains
(2012)
The bias-dependent oscillatory electron transport of monatomic sulfur chains sandwiched between gold electrodes is investigated with density functional theory and non-equilibrium Green's function method. At zero bias, in ...
OSNR monitoring using two fiber interferometers
(2010)
In-band OSNR from 5 to 30 dB of a single 10 G NRZ-OOK channel was measured by two fiber interferometers within an accuracy of ±0.5 dB without requirement for knowledge of the noise-free extinction ratio of the signal.
