The interaction between oppositely charged amino acids was studied by charge-transfer reversed-phase thin-layer chromatography. The dependence of the lipophilicity of Arg, Lys and Orn on the concentration of Glu, Asp, Gln and Asn in the eluent was considered to be related to the strength of interaction. The interaction of dibasic amino acids with Glu and Asp was stronger than with Gln and Asn. ...

Experimentally observed anisotropic ion heating in helicon plasma sources may result from the interaction of ions with ion-sound turbulence. The ion-sound turbulence develops due to excitation of the short scale, kinetic, parametric ion-sound instability. From the quasilinear equation for the ion distribution function, which includes the induced scattering of ion-sound waves by ions, the turbul...

In preparing this note, we have examined many textbooks of magnetism where the mechanism of the superexchange interaction is discussed. We realize that it may be difficult for readers (in particular graduate students and undergraduate students studying on the magnetism) to understand the physics on the superexchange interactions from these textbooks, partly because of the limited space of the t...

016101-1 Many chemically active, hazardous, and toxic substances have a high dipole moment, and they interact strongly with the charged particles and molecular ion clusters. A new nucleation model considering the contribution of the dipole-charge interaction to the ion-induced nucleation rates is developed, with the dipole moment of the condensing monomers as a new parameter. It is shown that i...

Calcium ion is the ubiquitous messenger in cells and plays a key role in neuronal signaling and fusion of synaptic vesicles. These vesicles are typically ∼20-50 nm in diameter, and thus their interaction with calcium ions cannot be modeled faithfully with a conventional flat membrane bilayer setup. Within our newly developed molecular dynamics simulations setup, we characterize here interaction...

Fluoride ion channels of the Fluc family combat toxicity arising from accumulation of environmental F-. Although crystal structures are known, the densely packed pore region has precluded delineation of the ion pathway. Here we chart out the Fluc pore and characterize its chemical requirements for transport. A ladder of H-bond donating residues creates a 'polar track' demarking the ion-conducti...

We present an analytic scheme to connect the fragility and viscoelasticity of metallic glasses to the effective ion-ion interaction in the metal. This is achieved by an approximation of the short-range repulsive part of the interaction, combined with nonaffine lattice dynamics to obtain analytical expressions for the shear modulus, viscosity, and fragility in terms of the ion-ion interaction. B...
