*Correspondence: Murugesan Vijayakumar and Wei Wang, Energy and Environmental Directorate, Pacific Northwest National Laboratory, 902 Battelle Blvd, P.O. Box 999, Richland, WA 99352, USA e-mail: [email protected]; [email protected] Lack of comprehensive understanding about the interactions between Nafion membrane and battery electrolytes prevents the straightforward tailoring of optimal materials ...
Phenols began to play a prominent role very early in modern operative medicine in the 1860s when Lister introduced his ‘antisepsis’ approach. The treatment of open wounds by carbolic acid dramatically reduced morbidity and mortality of surgical patients for the first time [1]. This central place in operative medicine was lost when, in the early 20th Century, ‘asepsis’ replaced ‘antisepsis’. The...
The past half century has seen an explosive growth of the discipline that is characterized by the deposition of localized high energy densities in solid matter, by means of energetic ions produced e.g. in particle accelerators. First the fundamentals of Ion-Solid Interaction are outlined. A brief overview is given about the basic energy transfer mechanisms and the consequences of ion impact int...
At pH 7 the bacteriophages T1 and T2 attach to anionic exchangers when suspended either in distilled water or in salt solutions. They attach to cationic exchangers only in the presence of salt. T2 requires approximately ten times higher a salt concentration than does T1 virus, a relationship which is duplicated in the attachment of these phages to their common host cell, E. coli B. The host cel...
A nanocomposite membrane Cu2+ ion-selective electrode has been constructed using a new compound ethyl 1,2,3,4-tetrahydro-4-(4-methoxyphenyl)-6-methyl-2-oxopyrimidine-5-carboxylat (ETMOC) as a neutral ionophore. The electrode works properly. It responds to Cu2+ ion with a sensitivity of 29.5 ± 0.2 mV/decade over the range 1.0 × 10−9 to 5.0 × 10−1M at p...
A numerical model of the nonlinear interaction between beating electrostatic waves and magnetized ions, including collisions, is presented. Previous studies of the beating electrostatic waves (BEW) interacting with a single ion showed the ability of this mechanism to accelerate ions from arbitrarily low initial velocities, and have revealed the fundamental conditions for this interaction to occ...
In recent years, ionic liquids have been used in pharmaceutical processes. Therefore, having a deep insight into the ion association behavior of ionic liquids in the presence of a drug is of particular importance. So, in this work, the molar conductivities of the ionic liquids, 1-alkyl-3-methylimidazolium bromide, [CnMIm]Br (n = 4, 6 and 8) in various concentrations of aspirin (ASA) ...
Interaction of Pb(II) ion with modified banana shell (MBS) and banana shell (BS) during adsorption fromaqueous solution were investigated. Batch experiments were carried out to investigate the effect of contact time,pH, and IDMID ion concentration on adsorption efficiency. The favorable pll for maxim= Pb(II) adsorptionwas at 5.0. For the investigated IMOI) concentrations (10-80 mph), maximum ad...
The interaction of Congo Red CR with a series of Alkyltrimethylamoniumbromide CnTAB, N-hexadecylpyridinium bromide CPB and N-hexadecylpyridinium CPC were investigated using conductometry technique. It was observed that the formation of dye-surfactant ion pairs takes place at surfactant concentration far below the critical micelle concentration of the individual surfactants. Aggregation was refl...
