Electrochemical Reduction of Chromate in the Presence of Nickel Chloride in Molten Lithium Chloride-Potassium Chloride Eutectic
Chronopotent iometry of chromate in the presence of NiC12 in molten LiCIKCI eutectic reveals a diffusion controlled, three electron reduct ion step. In the presence of excess NiC12, chromate is reduced at --0.35V vs. P t ( I I ) / P t reference electrode and the electroactive species responsible for the chronopotentiometric wave is estimated to have a diffusion coefficient of 1.06 9 10 -5 cm 2 ...
متن کاملElectrochemical Reduction of Indium (III) in Molten Lithium Chloride - Potassium Chloride Eutectic
The dependence of indium electro de potential vs. log. concentration of indium (III) is linear and the slopes determined are comparable with the slopes calculated from the Nernst equation, assuming n = 3. The potential of In/ln(III) has been determined to be 0.805 ± 0.003 V with respect to Pt/PtC12 (1 M). At 693 K the free energy of formation of the indium(III) chloride in a 1 M solution is -32...
متن کاملElectrochemical Reduction of Molybdenum(VI) Compounds in Molten Lithium Chloride-Potassium Chloride Eutectic
Molybdenum(VI) oxide reacts with molten LiC1-KCI eutectie at 450 ~ to form MOO2C12, which probably is present as an anion MoO2Cl4 =, and pyromolybdate, Mo207 =. Both of these species are electrochemically reduced to MOO2, which can be reoxidized to MoO2CI2 by current reversal. A second reduction step, observed whether MoO3 or Mo2072is added to the melt, can be attributed to the reduction of MoO...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Direct electrochemical reduction of titanium-bearing compounds to titanium-silicon alloys in molten calcium chloride
Titanium-silicon alloys have been electrochemically extracted from the multi-component titanium compounds in molten calcium chloride electrolyte. Sintered pressed pellets of titanium-bearing compounds served as the cathode, and the electrochemical experiments were systematically carried out at 900 °C, 3.1 V and 1000 °C, 3.8 V using a graphite-based anode and an improved inert-oxygen-ion-conduct...
