Control of quantum transmission is trap free

10-Feb-2014 | Alexander N. Pechen, David J. Tannor, Canadian Journal of Chemistry, 2014

Canadian Journal of Chemistry, Volume 92, Issue 2, Page 157-159, February 2014. We consider manipulation of the transmission coefficient for a quantum particle moving in one dimension where the shape of the potential is taken as the control. We show that the control landscape, the ...

Exploration of the α-effect by substitution on hydroxylamine anions. I. Effects of alkyl- and fluoroalkylation

10-Feb-2014 | D. Afzal, K.R. Fountain, Canadian Journal of Chemistry, 2014

Beaucoup d’explications de l’effet alpha ont été proposées, la plupart du temps sous la forme de modèles simples supposant que diverses sources pouvaient influencer le comportement nucléophile. Le présent article décrit une étude exhaustive des effets électroniques réalisée à partir du doublet ...

β-Carotene autoxidation: oxygen copolymerization, non-vitamin A products, and immunological activity

03-Feb-2014 | Graham W. Burton, Janusz Daroszewski, James G. Nickerson, James B. Johnston, Trevor J. Mogg, Grigory B. Nikiforov, Canadian Journal of Chemistry, 2014

Canadian Journal of Chemistry, Volume 0, Issue 0, Page 305-316, e-First articles. Carotenoids are reported to have immunological effects independent of vitamin A activity. Although antioxidant activity has been suggested as a basis of action, the ability of carotenoids to autoxidize to ...

Synthesis, structure, and properties of the hexagermane Pri3Ge(GePh2)4GePri3

03-Feb-2014 | Kimberly D. Roewe, James A. Golen, Arnold L. Rheingold, Charles S. Weinert, Canadian Journal of Chemistry, 2014

La synthèse de l’hexagermane Pri3Ge(GePh2)4GePri3 a été réalisée à partir d’un cyclotetragermane (Ph2Ge)4. L’ouverture du cycle de (Ph2Ge)4 en présence de Br2 a donné la molécule Br(GePh2)4Br, qui a été convertie en H(GePh2)4H. Celle-ci est mise en présence de deux espèces de formule Pri3GeNMe2 ...

Density functional theory studies of methanol adsorption and decomposition mechanism on Al13 clusters

27-Jan-2014 | Cai-Chao Ye, Feng-Qi Zhao, Si-Yu Xu, Xue-Hai Ju, Canadian Journal of Chemistry, 2014

Nous avons étudié l’adsorption et la décomposition de la molécule CH3OH en présence d’agrégats Al13 à l’aide de l’approximation des gradients généralisée de la théorie de la théorie de la fonctionnelle de la densité. L’intensité élevée des forces d’attractions qui existent entre la molécule CH3OH ...
