High stiffness nano-composite fibres from polyvinylalcohol filled with graphene and boron nitride
(2016)
Here we describe using nanosheets of both graphene and boron nitride, produced
by liquid phase exfoliation, as fillers in composite fibres. The fibres were prepared by
coagulation spinning using polyvinylalcohol as a ...
LEMUR: Large European Module for solar Ultraviolet Research. European contribution to JAXA's Solar-C mission
(2012)
Understanding the solar outer atmosphere requires concerted, simultaneous solar observations from the visible to the vacuum ultraviolet (VUV) and soft X-rays, at high spatial resolution (between 0.1" and 0.3"), at high ...
Models of wet two dimensional foams
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)
In this thesis I used models and computer simulations to investigate the
properties of two dimensional polydisperse foams from the dry limit of zero
liquid fraction to the wet limit of 0.16 liquid fraction.
Initially I ...
Band structures of rare gas solids within the GW approximation
(2005)
Band structures for solid rare gases

have been calculated using the
GW
approximation. All electron
and pseudopotential
ab initio
calculations were performed using Gaussian orbital basis sets and the ...
Fields and flares : understanding the complex magnetic topologies of solar active regions
(Trinity College (Dublin, Ireland). School of Physics, 2013)
Sunspots are regions of decreased brightness on the visible surface of the Sun (photosphere) that are associated with strong magnetic fields. They have been found to be locations associated with solar flares, which occur ...
Sublattice asymmetry of impurity doping in graphene: A review.
(2014)
In this review we highlight recent theoretical and experimental work on sublattice asymmetric doping of impurities in graphene, with a focus on substitutional nitrogen dopants. It is well known that one current limitation ...
Origin of the n-type and p-type conductivity of MoS2 monolayers on a SiO2 substrate
(2013)
Ab initio
density functional theory calculations are performed to study the electronic properties of a MoS
2
monolayer deposited over a SiO
2
substrate in the presence of interface impurities and defects. When ...
Measuring the lateral size of liquid-exfoliated nanosheets with dynamic light scattering
(2013)
We have developed an in-situ method to estimate the lateral size of exfoliated nanosheets dispersed in a liquid. Using standard liquid exfoliation and size-selection techniques, we prepared a range of dispersions of graphene, ...
Ferromagnetic resonance damping mechanisms in CoFeB thin films with Cr substitution
(2023)
The substitution of iron atoms by chromium in CoFeB films has been proposed to reduce the critical current density Jc for current-driven magnetization switching in spin transfer torque devices by reducing its magnetization. ...
Large magnetorefractive effect in magnetite
(2010)
We carried out a magneto-optical spectroscopic study of magnetite (Fe3O4) thin films and single crystals at optical wavelengths. We observed a relevant quadratic magneto-optic contribution that can be notably larger than ...
