Electrochemical Impedance Spectroscopy (EIS) characterization for electrochemical processes in Lithium Thionyl Chloride reserve primary battery is shown. Two different electrolyte compositions are used to distinguish the changes EIS response. Galvanostatic at discharge technique obtain Kramers-Kronig compatible data battery. The analyzed by means of Equivalent Circuit models. analysis shows pre...

Georges Darzen's name is absent from the Dictionary of Scientific Biography. This is a regrettable omission, on three grounds. He was a creative organic chemist, to whom we owe both the thionyl chloride conversion of alcohols into chlorides and the "Darzens reaction"—an addition-fragmentation which can be seen as the forerunner to the Wittig reaction. He was a perceptive observer of the scienti...

A novel sodium N-fatty acyl amino acid (SFAAA) surfactant was synthesized using pupa oil and pupa protein hydrolysates (PPH) from a waste product of the silk industry. The aliphatic acids from pupa oil were modified into N-fatty acyl chlorides by thionyl chloride (SOCl2). SFAAA was synthesized using acyl chlorides and PPH. GC-MS analysis showed fatty acids from pupa oil consist mainly of unsatu...

COBBER (ClOud OBservER), is a mid-infrared sky monitor featuring a 10μm Perkin-Elmer TPS534 thermopile detector. Radiation is focussed on to the detector through an anti-reflection coated, hemispherical ZnSe lens, providing a 30◦ field of view on the sky. At 10cm in length and 4cm diameter, the tiny cloud monitor was designed for ease of transportation and an extremely low power budget. Run in ...
