Studies of Corrosion of Aluminium and 6063 Aluminium Alloy in Phosphoric Acid Medium
The corrosion behaviour of aluminium and6063 aluminium alloy was investigated in phosphoric acid of different concentrations at different temperatures. The study was done by electrochemical method, using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques. The kinetic parameters and thermodynamic parameters were calculated using Arrhenius theory and transition state t...
متن کاملsemi-analytical solution for static and forced vibration problems of laminated beams through smooth fundamental functions method
در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...
15 صفحه اولHigh frequency sonoluminescence in sulphuric acid and phosphoric acid
Multibubblesonoluminescence (MBSL) emission spectra at different forcing frequencies ( 20, 580, 850 KHz and 1.1 MHz) in Sulphuric acid and Phosphoric acid, under different noble gases atmosphere ( Ar, Xe and He) have been investigated. Using lower frequency we observed the presence of new emissions lines which may indicate the formation of ionized species with very high energy level inside the ...
متن کاملOxygen Reduction on Gas-Diffusion Electrodes for Phosphoric Acid Fuel Cells by a Potential Decay Method
The reduction of gaseous oxygen on carbon-supported plat inum electrodes has been studied at 150~ with polarization and potential decay measurements. The electrolyte was either 100 weight percent phosphoric acid or that acid with a fluorinated additive, potassium perfluorohexanesulfonate (C6FI3SO3K). The pseudo-Tafel curves of the overpotential vs. log (iiL/(iL -i)) show a two-slope behavior, p...
متن کاملA Method for the Determination of Adenosine- 5’-phosphoric Acid and Its Homologues*
For the determination of adenosine-5’-phosphoric acid and its homologues the methods which have been recommended chiefly are (1) enzymatic deamination by deaminase and quantitative determination of the ammonia split off (1) ; (2) determination on the basis of the pharmacological activity, (a) contraction of the isolated guinea pig uterus, (b) the characteristic change in the electrocardiogram u...
