Efficient and Green Route to γ‐Lactams by Copper‐Catalysed Reversed Atom Transfer Radical Cyclisation of α‐Polychloro‐N‐allylamides, using a Low Load of Metal (0.5 mol%)
16-05-2013 | Franco Bellesia, Andrew J. Clark, Fulvia Felluga, Armando Gennaro, Abdirisak A. Isse, Fabrizio Roncaglia, Franco Ghelfi, Advanced Synthesis & Catalysis, 2013
Abstract The cyclisation of N‐allyl‐N‐substituted‐α‐polychloroamides is efficiently obtained through a copper‐catalysed activators regenerated by electron transfer–atom transfer radical cyclisation process, with a metal load of only 0.5 mol%. The redox catalyst is introduced in its ...

Assessment of the surface reactivity of AA1050 aluminium alloy
01-05-2013 | Malgorzata Witkowska, George Edward Thompson, Teruo Hashimoto, Elena Koroleva, Surface and Interface Analysis, 2013
During processing from cast slab to thin gauge material, the AA1050 aluminium alloy proceeds through various stages of thermomechanical processing, with the conditions at each processing stage influencing the microstructure of the final coil. The reactivity of the material in defined ...
Iodine(I) Reagents in Hydrochloric Acid‐Catalyzed Oxidative Iodination of Aromatic Compounds by Hydrogen Peroxide and Iodine
30-04-2013 | Leon Bedrač, Jernej Iskra, Advanced Synthesis & Catalysis, 2013
Abstract Hydrochloric acid activates the oxidative iodination of aromatic compounds with the iodine‐ hydrogen peroxide system through the formation of an iodine(I) compound as the iodinating reagent. Activation with hydrochloric acid is more powerful than that with sulfuric acid. The ...

Investigation of an explosion in a gasoline purification plant
24-04-2013 | Trygve Skjold, Kees Wingerden, Process Safety Progress, 2013
An explosion in an atmospheric storage tank initiated additional tank explosions and a pool fire at a tank facility in Norway. The tank farm had been operated as a purification plant for a petroleum product called coker gasoline. The process entailed extraction of malodorous sulfur ...

Preparation of a clean Ge(001) surface using oxygen plasma cleaning
03-04-2013 | Patrick Ponath, Agham B. Posadas, Richard C. Hatch, and Alexander A. Demkov, Journal of Vacuum Science & Technology B, 2013
The authors demonstrate a method to obtain a clean and smooth Ge (001) surface using oxygen plasma cleaning without sputtering or Ge regrowth. The preparation of the germanium surface consists of four cycles of ex situ wet etching using hydrochloric acid as the etchant and H2O2 as the ...
Water O–H Stretching Raman Signature for Strong Acid Monitoring via Multivariate Analysis
02-04-2013 | Amanda J. Casella; Tatiana G. Levitskaia; James M. Peterson; Samuel A. Bryan, Analytical Chemistry, 2013
A distinct need exists for real time information on an acid concentration of industrial aqueous streams. Acid strength affects efficiency and selectivity of many separation processes, including nuclear fuel reprocessing. Despite the seeming simplicity of the problem, no practical solution has ...
