2-(2-Hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl ester (Picaridin), and 1-(cyclohex-3-ene-1-ylcarbonyl)-2-methylpiperidine (AI3-37220; 220) are alternatives to DEET (N,N-diethyl-3-methylbenzamide), the most popular mosquito repellent. Picaridin and AI3-37220 exhibit polychiral diastereoisomerism and each has four diastereoisomers due to the(More)
Corrosion behavior of Nitinol (nickel titanium) alloy has been examined in physiological Ringer's solution by means of electrochemical techniques (open-circuit potential measurement, potentiodynamic and potentiostatic polarizations) and capacitance measurements. The results show that the passive film is stable at open-circuit condition, but many of anodic(More)
The surface conductivity of copper, silver, tin and lead at 24,000 Mc/sec has been measured as a function of temperature over the interval 3000K to 40°K by means of resonant cavity techniques. Only the normal (non-superconducting) state has been investigated. The influence of surface roughness on the impedance has been determined qualitatively for copper.(More)
