A new type of sesqiterpene lactone isolated from artemisia annua L. arteannuin B
(Elsevier, 1973)
The structure of a new sesquiterpene lactone, arteannuin B, isolated from Artemisia annua L. is reported.
Complex plane analysis in electrode modulated specular reflectance studies
(AIP Publishing, 1973)
Optical specular reflection is finding extensive use for studies of electrode-electrolyte interfaces. The purpose of this Note is to call attention to the use of complex plane analysis to obtain kinetic information concerning ...
Individual ionic activities and mass transfer in anodic chlorate formation
(Switzerland : Springer Nature, 1973)
The individual activity of hypochlorite ion in concentrated neutral salt (NaCl-NaClO3) solutions has been estimated kinetically by measurement of the Faradaic efficiency in a chlorate producing system comprised of a cell ...
Vapor-Deposited Gold Electrodes: Effects of Undercoatings
(IOP Publishing, 1973)
Vapor-deposited metal-film electrodes on smooth glass substrates are attractive for optical reflectance studies of electrochemical systems because of the high optical quality of the surface and a ratio of true to apparent ...
Carbon-air electrode with regenerative short time overload capacity: Part 1. Effect of manganese dioxide
(Springer Nature, 1973)
To increase the overload capacity of the carbon-air electrode in alkaline electrolyte, without seriously changing the electrode potential during short-time overload periods, small amounts of MnO2 were added to carbon and ...
Extractives of Artemisia scoparia
(Elsevier, 1973)
Artemisia scoparia collected south of Belgrade was used. Capillin, 1-phenyl-2,4-hexa-diyne-1-ol, vanillin, and scoparone were isolated. All compounds were identified by direct comparison with authentic materials, by m.m.p., ...
Pulsating potential electrolysis in the deposition of copper
(Elsevier, 1973)
A very low impedance circuit was constructed in order to provide a pulsating cathodic potential for a copper electrode immersed in a copper sulphate solution of the type used in copper refining. The increase in surface ...
The possibility of separating hydrogen fluoride from its gaseous mixture with silicon tetrafluoride
(Elsevier, 1973)
We report in this paper investigations of the conditions necessary to effect the selective absorption of hydrogen fluoride from its gaseous mixture with silicon tetrafluoride when that mixture is brought into contact with ...
The polarographic behavior of metal ions in molten LiNO3-KNO3 eutectic in presence of complexon III
(Elsevier, 1973)
The possibility of using complexon III as a complexing substance in the polarography of salt metls (LiNO3-KNO3 eutectic) has been investigated. Complexon III was found to form complexes with Cd, Pb, Ni and Zn ions in the ...
