Modeling and Characterization of Rate Phenomena in Complex Electrochemical Systems: Sodium-Metal Chloride Batteries and Ni/SiC Co-Deposition
… second part of the dissertation, a sodium-metal chloride battery, which is another important complex electrochemical system, is studied. A one-dimensional mathematical model of the porous cathode of a sodium-iron chloride battery for an isothermal, constant-current discharge-charge cycle is …

Development of hybrid organic-inorganic light emitting diodes using conducting polymers deposited by oxidative chemical vapor deposition process
… rinsing step required with other oxidants like iron chloride and hence makes the process completely dry. Accelerated aging experiments show longer retention of electrical conductivity for the PEDOT films obtained using bromine as the oxidant. Conductivities as high as 380 S/cm were obtained for …

Investigation of copper deposition on steel in molten copper chloride
… for clean energy generation. The Copper Chloride (Cu-Cl) cycle has been chosen as an effective cycle for production of hydrogen due to its comparatively lower operating temperatures and cost. While most materials subjected to the molten Cu-Cl environment are bound to corrode, stainless …

Crystallographic studies on enzymatic halogenation of natural products
… flavin-dependent halogenases and the non-heme iron dependent halogenases. Structures of the flavin-dependent tryptophan 7-halogenase RebH from Lechevalieria aerocolonigenes, involved in rebeccamycin biosynthesis, were solved by molecular replacement. These structures show distant flavin and …

Microstructured materials synthesis via salt-assisted ultrasonic spray pyrolysis
… process using inexpensive and, often, environmentally-friendly precursors. The incorporation of an inert or reactive salt into the precursor solution allows for structural modification of the final product. Inert salts can phase separate as either liquids or solids (depending on the …

Study of the effect of molten CuCl immersion test on alloys with high Ni-content with and without surface coatings
… underneath the coating. Copper deposits and iron chloride that were found on the sample surfaces suggest that there were corrosion reactions that involved the metal dissolution and reduction of copper during immersion test. The results also suggest that Inconel 625 performed better than …

Carbon Dioxide Flooding Induced Geochemical Changes in a Saline Carbonate Aquifer
… than 300,000 ppm total dissolved solids. Sodium chloride (NaCl) is the primary salt of the formation waters of the Madison Group. Water-alternating-gas (WAG) flooding experiments were conducted on limestone rock cores using a core flooding system that simulates the CO2 injection process at …

Biosynthesis of copper nanoparticles using a bioflocculant from Alcaligenis faecalis, characterization and its application
… observed when compared to the bioflocculant and iron chloride in kaolin clay, mine water, industrial waste water and domestic waste water. The highest flocculating activity was achieved with the lowest concentration of CuNPs (0.002g/L) with 96% and the least activity was 80% at 0.01g/L. The …

Low Temperature Phase Relations in the System H2O-NaCl-FeCl2
… O2. The clear color is characteristic of ferrous iron solutions, whereas the yellow-orange color is consistent with the presence of Fe3+ in solution. This color change suggested that the unopened capsules initially contained ferrous iron in solution, which oxidized to ferric iron when exposed to …
