Electrochemical Technology

  1. 1. Scientific Potential ofDepartment of ElectrochemicalProduction Technology,Vyatka State UniversityPh.D, Prof. Shishkina Svetlana Vasiljevna
  2. 2. History of Department- The training of engineers for electrochemical processes wasorganized in 1963 in Kirov Polytechnic Institute (now Vyatka StateUniversity).- The science researches about electroplating were started from1967 with collaboration of young lecturers and students of senioryears- The Department of Electrochemical Production Technology wasestablished in 1969 according to order of Ministry of HighEducation (RSFSR) »
  3. 3. Major research development of Department- Studies of hydrogen absorption under electroplating. Connectionbetween hydrogen absorption and pH of near-electrode layer wasdetected and investigated. T.M. Ovchinnicova and L.I. Kovyazinawere decorated by medal of ENEA after training to perfection ofelectrolyte for cadmium coating without hydrogen absorption- Effect of pH of near-electrode layer upon stability of sodiumamalgam was investigated. Results permitted to select optimal pHfor electrolysis in production of chlorine and alkali on Kirov-Chepetsk chemical plant.Four Ph.D theses were defended under the guidance ofOvchinnicova T.M.
  4. 4. Major research development of Department- The technology of manufacture of cathodes from coppermonochloride was developed and introduced for replacement ofsilver chloride in wateractivated chemical current sources ofspecial purpose.- The research of processes in medium temperature Li-Saccumulator was performed for creation of transport energysource.Five Ph.D theses were defended under the guidance ofKhranilov Yu.P . and Shishkina S.V
  5. 5. Department have modern equipment forscientific research: potentiostates “Volta” and“Elins”, impedancemeter «Z-2000» withcomputer control, have pilot galvanic line withmodern venting and rectifier devices.Department carry out scientific research withuse of infrared spectrometer, a differentialscanning calorimeter, derivatograph, belongingto science education center of Vyatka StateUniversity.Department use scanning and atomic forcemicroscopy (of science education center“Nanotechnology”) for study the surfaceproperties of different objects.
  6. 6.
