(Blackwell Publishing Ltd, 2001)We study ion acoustic damping effects on parametric decays of right-hand-polarized electromagnetic waves. We do this because ion beams have been observed in a variety of space environments, and consequently, these waves ...
-
(Blackwell Publishing Ltd, 2005)[1] It is shown that ion-acoustic waves propagating along an external magnetic field and generated by parametric decays of circularly polarized finite amplitude waves have the properties of ion-acoustic waves observed ...
-
(Blackwell, 2006)We consider a fast solar wind-type plasma consisting of electrons, a protons background, and a much more tenuous alpha particle beam. It is shown that such system is unstable against ion acoustic-like waves triggered by ...
-
(ELSEVIER, 2006-01)Incorporation of Alzheimer's disease amyloid beta-proteins (A beta Ps) across natural and artificial bilayer membranes leads to the formation of cation-selective channels. To study the peptide-membrane interactions involved ...
-
(1986)The light-activated conductance of Limulus ventral photoreceptors was studied using the patch-clamp technique. Channels (40 pS) were observed whose probability of opening was greatly increased by light. In some cells the ...
-
(Kluwer Academic Publishers-Plenum Publishers, 1988)The olfactory epithelium has the ability to respond to a large number of volatile compounds of small molecular weight. Ultimately, such a property lies on a specialized type of neuron, the olfactory receptor cell. In the ...
-
(1992)Fusion of Bacillus subtilis plasma membrane vesicles with planar lipid bilayers induced the appearance of discrete current fluctuations characteristic of ion channels. These channels showed a wide range of conductances and ...
-
(John Wiley and Sons, 1994)A cell line (RCDMD), derived from a muscle biopsy taken from a 7-year-old patient with Duchenne muscular dystrophy (DMD), was established in vitro using conditioned media from the UCHT1 thyroid cell line as described ...
-
(1993)Batrachotoxin-modified Na+ channels from toad muscle were inserted into planar lipid bilayers composed of neutral phospholipids. Single-channel conductances were measured for [Na+] ranging between 0.4 mM and 3 M. When ...
-
(Blackwell Publishing Ltd, 2003)In a recent study of ion cyclotron waves generated by the thermal anisotropy of oxygen ions, it was shown that the heavy ion drift velocity and a large thermal anisotropy of the heavy ions can destabilize proton-cyclotron ...
-
Ion cyclotron instability triggered by drifting minor ion species: Cascade effect and exact results (2004)On the basis of bi-Maxwellian velocity distribution functions it has been recently shown that the combined effect of heavy ion thermal anisotropy and drift velocity can trigger ion-cyclotron instabilities beyond the ...
-
(1996)We study the linear and nonlinear properties of electromagnetic ion-cyclotron waves in the magnetosphere and the solar wind. In particular, we study parametric decays of large amplitude electromagnetic ion-cyclotron waves ...
-
(Nature Publishing Group, 2018)Nanoparticles are ubiquitous in nature and are increasingly important for technology. They are subject to bombardment by ionizing radiation in a diverse range of environments. In particular, nanodiamonds represent a variety ...
-
(Sociedad Chilena de Quimica, 2015)In this work, we report a fast and accessible method for quantification of cetyltrimethylammonium bromide (CTAB) in solutions of gold nanorods (GNRs) by bromophenol blue (BPB) ion-paring formation and spectrophotometric ...
-
(Editorial Codelia, 1986)Self Consistent Reaction Field (SCRF) ealculations, including dielectric solvent effects, have been performed to analyze the relative stabilities of the different chernical species found in substitution reactions involving ...
-
(Elsevier, 1986)The presence of four cation pathways in membrane vesicles isolated from transverse tubules of frog and rabbit skeletal muscle was studied by measuring binding of specific blockers. Transverse tubules purified from frog ...
-
(1991)Na+ permeation through normal and batrachotoxin (BTX)-modified squid axon Na+ channels was characterized. Unmodified and toxin-modified Na+ channels were studied simultaneously in outside-out membrane patches using the ...
-
(1991)Electrostatic solvation energies of singly charged monoatomic ions may be predicted from the knowledge of an electrostatic potential buildup from a physically meaningful ionic radius. Since the asymptotic behavior of the ...
-
(1994)A Kohn-Sham (KS) like formalism for the calculation of solvation energies of singly charged ions is presented. The approximate theory is based on a simple model that represents embedding an atomic ion into a polarizable ...
-
(Blackwell Publishing Ltd, 2006)Nonlinear ion-acoustic like waves triggered by large-amplitude circularly polarized waves propagating in the direction of a proton beam are studied. The properties are strongly dependent on the nature of the large-amplitude ...
