Several prokaryotic ClC proteins have been demonstrated to function as exchangers that transport both chloride ions and protons simultaneously in opposite directions. However, the path of the proton through the ClC exchanger, and how the protein brings about the coupled movement of both ions are still unknown. In this work, we use an atomistic molecular dynamics (MD) simulation to demonstrate t...
This two-part study explores the development and thermal performance of a coiled-tube heat exchanger for hydrogen fuel cell storage systems utilizing High-Pressure Metal Hydride (HPMH). The primary purpose of this heat exchanger is to tackle the large amounts of heat released from the exothermic hydriding reaction that occurs when the hydrogen is charged into the storage vessel and is absorbed ...

Removal of chromium complex dye from aqueous solutions by sorption onto a weakly basic, acrylic matrix anion exchanger Purolite A845 and a strongly basic, polystyrene matrix anion exchanger Purolite A 500P has been investigated under various experimental conditions: the initial dye concentration, pH and temperature. The sorption of chromium complex dye proceeds as a result of miscellaneous inte...

Dissertationes Biocentri Viikki Universitatis Helsingiensis 17/2002, pp. 57 ISBN 952-10-0313-8 (print) ISBN 952-10-0314-6 (pdf) ISSN 1239-9469 A common aim in the development of new transdermal devices is the controlled delivery of drugs, so that the rate of drug input into the blood stream is pred...
Studies of ion transport pathophysiology in hematological disorders and tests of possible new therapeutic agents for these disorders have been carried out in various mouse models because of close functional similarities between mouse and human red cells. We have explored strain-specific differences in erythrocyte membrane physiology in 10 inbred mouse strains by determining erythrocyte contents...
The main goal of this study was to prepare and characterize ion exchangers on nanofibrous polystyrene matrix. Starting nanofibers were sulfonated and crosslinked at the same time by sulfuric acid. Strongly acidic cation exchanger was obtained in such a way. Anion exchanger was prepared by reaction of ethylene diamine with sulfochlorides on nanofibers acquired from sulfogroups. The polymer matri...
CLC-ec1 is a prokaryotic CLC-type Cl(-)/H+ exchange transporter. Little is known about the mechanism of H+ coupling to Cl-. A critical glutamate residue, E148, was previously shown to be required for Cl(-)/H+ exchange by mediating proton transfer between the protein and the extracellular solution. To test whether an analogous H+ acceptor exists near the intracellular side of the protein, we per...
