Lateral Size Selection of Surfactant-Stabilised Graphene Flakes using Size Exclusion Chromatography
(2012)
Aqueous dispersions of graphene, stabilised by a surfactant, have been separated according to lateral flake size using size exclusion chromatography. Transition electron microscopy was used to characterise the flake size ...
Magnetic field effects on electrodeposition and the properties of electrodeposited nickel and nickel-copper
(Trinity College (Dublin, Ireland). School of Physics, 2004)
The association of magnetism and electrodeposition is studied from two separate perspectives.
Firstly the effect of an applied magnetic field on the deposition process and
secondly the production of magnetic materials by ...
On the relationship between income, fertility rates and the state of democracy in society
(2016)
Empirical data for 145 countries shows a strong correlation between the gross national income per capita and the political form of their governance, as specified by the so-called democracy index. We interpret this relationship ...
Simulating STM transport in alkanes from first principles
(2009)
Simulations of scanning tunneling microscopy
STM
measurements for molecules on surfaces are tradi-
tionally based on a perturbative approach, most typically employing the Tersoff-Hamann method. This assumes
that the ...
Reduced low frequency noise in electron beam evaporated MgO magnetic tunnel junctions
(2010)
We compare low frequency noise in magnetic tunnel junctions with MgO barriers prepared by electron-beam evaporation with those prepared by radiofrequency sputtering, both showing a high tunneling magnetoresistance. The ...
The continuum theory of shear localization in two-dimensional foam
(2010)
We review some recent advances in the rheology of two-dimensional
liquid foams, which should have implications for three-dimensional foams, as well
as other mechanical systems that have a yield stress. We focus primarily ...
Resonance tuning of two-photon absorption microcavities for wavelength-selective pulse monitoring
(2006)
We showthe potential use of a single photodetector for
multichannel pulse monitoring. Two-photon absorption in a microcavity
structure is used as the nonlinear optical technique for pulse
monitoring. Angle tuning of the ...
Electrically Driven Reprogrammable Vanadium Dioxide Metasurface Using Binary Control for Broadband Beam Steering
(2022)
Resonant optical phased arrays are a promising way to reach fully reconfigurable metasurfaces in the optical and near-infrared (NIR) regimes with low energy consumption, low footprint, and high reliability. Continuously ...
Impurity invisibility in graphene: Symmetry guidelines for the design of efficient sensors
(2016)
Renowned for its sensitivity to detect the presence of numerous substances, graphene is an excellent chemical sensor. Unfortunately, which general features a dopant must have in order to enter the list of substances ...
Three dimensional confocal microscopy of fluorescent microspheres: Imaging and size determination
(SPIE, 2005)
In this paper, we experimentally studied both the bright-field and fluorescence images of microspheres by
conventional and confocal scanning polarization microscopes. A qualitative analysis have been given to show a
physical ...
