in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
Stainless steel bipolar plates are preferred choice for use in Proton Exchange Membrane Fuel Cells (PEMFCs). However, regarding the working temperature of 80 °C and corrosive and acidic environment of PEMFC, it is necessary to apply conductive protective coatings resistant to corrosion on metallic bipolar plate surfaces to enhance its chemical stability and performance. In the present study...
Dear Sir: Studies on intracellular electrical potentials in a variety of epithelial tissues which are involved in transmural Na transport have resulted in an apparent dichotomy. In tissues characterized by high transmural resistances such as isolated frog skin (1, 2), toad skin (3), and toad urinary bladder (4), the cell interior is electrically positive with respect to the outer or mucosal sol...
OBJECTIVES The aim of this study was to evaluate the phenomenon of electrical skin resistance (ESR) changes at different acupuncture points (APs). SETTING This single-blinded study was performed at the hospital of the University of Munich. DESIGN Six common APs were measured (TE5, PC6, LU6, ST36, SP6, GB39) in 53 subjects. Subgroups were formed with varying time intervals for follow-ups (1 ...
