Josephson current in a superconductor-ferromagnet junction with two non-collinear magnetic domains
We study the Josephson effect in a superconductor--ferromagnet--superconductor (SFS) junction with ferromagnetic domains of non-collinear magnetization. As a model for our study we consider a diffusive junction with two ferromagnetic domains along the junc ...
2006pH Controlled Diffusion of Proteins with Different pI Values across a Nanochannel on a Chip
Philippe Renaud, Arnaud Bertsch, Reto Bruno Schoch
Electrostatic interactions dominate the diffusion of proteins in a nanochannel, which was measured and modeled for pH values above and below the isoelectric points of three lectin proteins. Maximal diffusion coefficients were obtained when the proteins wer ...
2006Nanoparticle Adsorption on a Weak Polyelectrolyte. Stiffness, pH, Charge Mobility, and Ionic Concentration Effects Investigated by Monte Carlo Simulations
Monte Carlo simulations have been used to study two different models for a weak linear polyelectrolyte in the presence of nanoparticles: (i) a rodlike and (ii) a flexible polyelectrolytes. The use of simulated annealing has made it possible to simulate a p ...
American Chemical Society2006The reactivity of 2-fluoro- and 2-chloropyridines toward sodium ethoxide: Factors governing the rates of nucleophilic (het)aromatic substitutions
The relative displacement rates of the halide substituent from 2-fluoro- and 2-chloropyridines by EtONa in EtOH at +25 Deg were assessed by competition kinetics. The 2-fluoropyridine reacts 320 times faster than the chloro analog. A CF3 group increases the ...
2005[η6-2-(2-Methylbenzoyloxy)ethyl methacrylate]bis(η6-1,2,4,5-tetramethylbenzene)tri-μ-hydrido-μ3-oxo-triruthenium(II)(3Ru—Ru) tetrafluoroborate
The trinuclear arene-ruthenium cluster cation, Ru3H3(O)(C10H14)2(C14H16O4), has been synthesized and crystallized as the tetrafluoroborate (BF4-) salt. The cations form, along the b axis, infinite one-dimensional chains through pi-stacking interaction ...
2004pi-Stacking in charged thiophene oligomers
The :T-stacking of oxidized thiophene oligomers is investigated using extensive ab initio quantum chemistry methods. Dimers of singly charged oligothiophenes are unstable in the gas phase but can be stabilized as bound dications in the singlet state by a p ...
