Analytic models of heterogenous magnetic fields for liquid metal flow simulations
(2009)A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical ...

Dispersed-phase structure in sheared MHD turbulence
(2012)Direct numerical simulations are performed to examine particle dispersion in homogeneous turbulence subjected to mean shear and an externally applied magnetic field. We employ the Brucker et al. algorithm for simulating ...

Fabrication, characterization, and evaluation in drug release properties of magnetoactive poly(ethylene oxide)-poly(l -lactide) electrospun membranes
(2013)The fabrication of electrospun magnetoactive fibrous nanocomposite membranes based on the water-soluble and biocompatible poly(ethylene oxide) (PEO), the biocompatible and biodegradable poly(l-lactide) (PLLA) and preformed ...

A hexameric [Mn III 18 Na6] wheel based on [Mn III 3 O]7+ sub-units
(2016)A novel hexameric [MnIII18Na6] wheel-like aggregate consisting of [MnIII3O] triangles is reported. It is the second highest nuclearity oxime-based Mn cluster, the largest member of the recently-developed family of molecular ...

Magnetic-field-induced localization in networks with the T3 geometry
(2002)By following an exact analytical procedure we study the transmission properties of a network of quantum wires arranged in a so-called T3 configuration and in the presence of a perpendicular magnetic field. It is shown that ...

Measurement of the tt̄ production cross section in pp̄ collisions at √s=1.8 TeV
(2001)We update the measurement of the tt̄ production cross section using the CDF detector at the Fermilab Tevatron. This measurement uses tt̄ decays to the final states e+v+jets and μ+v+jets. We search for b quarks from t decays ...

A Mn 36Ni 4 'loop-of-loops-and-supertetrahedra' aggregate possessing a high S T = 26 ± 1 spin ground state
(2012)The initial use of 1,3-propanediol in mixed Mn/3d cluster chemistry has led to a Mn III 28Mn II 8Ni II 4 molecular aggregate which consists of two Mn III 8Ni 2 loops and two Mn III 6Mn II 4 supertetrahedral units and ...

Rewritable remote encoding and decoding of miniature multi-bit magnetic tags for high-throughput biological analysis
(2008)We have investigated a new magnetic labelling technology for high-throughput biomolecular identification and DNA sequencing. Planar multi-bit magnetic tags comprising a magnetic barcode formed by an ensemble of micron-sized ...

A single-chain magnet based on linear [MnIII2MnII] units
(2014)The synthesis, structural characterization and magnetic properties of a 1D coordination polymer based on a linear mixed valent [MnIII2MnII] repeating unit are described. It displays single-chain magnet (SCM) behaviour with ...

Strain-controlled magnetic domain wall propagation in hybrid piezoelectric/ferromagnetic structures
(2013)The control of magnetic order in nanoscale devices underpins many proposals for integrating spintronics concepts into conventional electronics. A key challenge lies in finding an energy-efficient means of control, as power ...

Two interacting charged particles in an Aharonov-Bohm ring: Bound state transitions, symmetry breaking, persistent currents, and Berry's phase
(2004)By using a Green's function procedure we determine exactly the energy spectrum and the associated eigen-states of a system of two oppositely charged particles interacting through a contact potential and moving in a ...

Unpaired and spin-singlet paired states of a two-dimensional electron gas in a perpendicular magnetic field
(2002)We present a variational study of both unpaired and spin-singlet paired states induced in a two-dimensional electron gas at low density by a perpendicular magnetic field. It is based on an improved circular-cell approximation ...
