Theoretical analysis of the performance of a foam fractionation column
(2014)
A model system for theory and experiment which is relevant to foam fractionation consists of a column of foam moving through an inverted U-tube between two pools of surfactant solution. The foam drainage equation is used ...
Long-range charge order on the Fe3O4(001) surface
(American Physical Society, 2004)
The Verwey transition in magnetite is of fundamental importance for the understanding of metal-insulator transitions but, in spite of being the subject of many studies over the last century, its nature is not fully understood. ...
Steps toward determination of the size and structure of the broad-line region in active galactic nuclei. XI. Intensive monitoring of the ultraviolet spectrum of NGC 7469
(American Institute of Physics, 1997)
From 1996 June 10 to July 29, the International Ultraviolet Explorer monitored the Seyfert 1 galaxy NGC 7469 continuously in an attempt to measure time delays between the continuum and emission-line fluxes. From the time ...
Plasmon-assisted Energy Transfer near Coated Metal Cylinders
(2013)
In this contribution we consider the decay and energy transfer rates of dipole emitters near dielectric-coated
metal cylinders. The surface plasmons excited at the surface of the metal core can act as a very efficient ...
Optical signal processing via two-photon absorption in a semiconductor microcavity for the next generation of high-speed optical communications network
(2006)
Due to the introduction of new broadband services,
individual line data rates are expected to exceed 100 Gb/s in
the near future. To operate at these high speeds, new optical
signal processing techniques will have to ...
The complex dynamics of flowing foam
(Trinity College (Dublin, Ireland). School of Physics, 2014)
We investigate the link between the non-linear macroscopic rheology of wet foams and the microscopic interactions at the bubble-scale, within the general framework of foams as a complex system. This rheology has been found ...
Size selection of dispersed, exfoliated graphene flakes by controlled centrifugation
(2012)
Liquid exfoliation of graphene generally results in flakes with lateral size of one micron or less on average, too small for many applications. In this paper we describe a method to separate an existing dispersion with ...
Field induced transition in the paramagnetic state of (Sm0.65Sr0.35))MnO3 associated with matnegic clusters
(American Physical Society, 1999)
The susceptibility of (Sm0.65Sr0.35)MnO3 shows an unusual temperature dependence above the Curie temperature which is attributed to the presence of small manganese-ion clusters with S?9. A field-induced transition is ...
Energy transfer processes in semiconductor quantum dots: bacteriorhodopsin hybrid system
(2009)
The potential impact of nanoscience on energy transfer processes in biomolecules was investigated on the example of a
complex between fluorescent semiconductor nanocrystals and photochromic membrane protein. The ...
A continuum description of the buckling of a line of spheres in a transverse harmonic confining potential
(2023)
A line of contacting hard spheres, placed in a transverse confining potential, buckles under compression or when tilted away from the horizontal, once a critical tilt angle is exceeded. This interesting nonlinear problem ...
