Wall slip of bubbles in foams
(American Institute of Physics, 2006)
We present a computational analysis of the flow of liquid foam along a smooth wall, as encountered
in the transport of foams in vessels and pipes. We concentrate on the slip of the bubbles at the wall
and present some ...
Ultrafast Optical Nonlinearity of Liquid Phase Exfoliated Pdse2 Nanosheets.
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
In recent years, the study of condensed matter and optical physics has resulted in increasing technological progress, and this study may be credited with a significant portion of current scientific research and technical ...
All-optical sampling based on two-photon absorption in a semiconductor microcavity for high-speed OTDM
(SPIE, 2005)
Future high-speed optical communications networks operating at data rates in excess of 100Gbit/s per channel
will require a sensitive and ultrafast technique for precise optical signal monitoring.1 The standard way ...
The solar origins and earth impacts of space weather
(Trinity College Dublin. School of Physics. Discipline of Physics, 2020)
Coronal Holes (CHs) are expansive, low density, open magnetic field regions which appear dark in extreme-ultraviolet (EUV) images of the solar corona. CHs are associated with the acceleration of the high speed solar wind ...

Probing the Dynamics of Topologically Protected Charged Ferroelectric Domain Walls with the Electron Beam at the Atomic Scale
(2020)
Dynamic charged ferroelectric domain walls (CDWs) overturn the classical idea that our electronic circuits need to consist of fixed components of hardware.[1,2] With their own unique electronic properties and exotic ...
Magnetic field effects on water and aqueous solutions
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
Claims of magnetic field effects on water and their potential use in a microfluidic channel are explored. The pendant drop method is used to measure the surface tension, which is calculated from the shape of the drop. The ...
Spin transfer torque magnetisation switching in MgO based magnetic tunnel junctions
(Trinity College (Dublin, Ireland). School of Physics, 2010)
Magnetic tunnel junctions (MTJ) are important magnetic elements that are
used as memory and sensor devices. In this thesis, first, the fundamentals of MTJs
were explored by investigating different tunnel barrier materials, ...
Conductance of a phenylene-vinylene molecular wire: Contact gap and tilt angle dependence
(2010)
Charge transport through a molecular junction comprising an oligomer of p-phenylene-vinylene between gold contacts has been investigated using density-functional theory and the nonequilibrium Green?s function method. The ...
Chromatic dispersion monitoring for high-speed WDM systems using two-photon absorption in a semiconductor microcavity
(2009)
This paper presents a theoretical and experimental investigation into the use of a two-photon absorption (TPA) photodetector for use in chromatic dispersion (CD) monitoring in high-speed, WDM network. In order to overcome ...
