poly (n-bromosuccinimide) (pnbs) as a mild, efficient, non-acidic, polymeric and heterogeneous catalyst was applied for simple conversion of epoxides into thiiranes by treatment with kscn or (nh2)2cs at room temperature. aliphatic and aromatic epoxides converted into their corresponding thiiranes under mild conditions. all reactions proceeded in short reaction times and afforded the correspondi...

Novel Catalytic Non-Thermal Plasma Reactor for the Destruction of Volatile Organic Compounds L. Kiwi-Minsker, Ch. Subrahmanyam and A. Renken Ecole Polytechnique Fédérale de Lausanne (GGRC-EPFL), CH-1015 Lausanne, Switzerland, Fax: +41-21693 31 90, [email protected] Summary A novel dielectric barrier discharge (DBD) reactor has been designed and tested for the abatement of diluted vol...

Dans un service de 36 lits de medicine in­fantile une periode de 18 mois, 33 enfants furent hospitalises pour une affection hematologique maligne: 21 cas de leucemie aigi.ie, 1 cas de leu­cemie myeloide chronique, 2 cas de lymphomes malins, 9 cas de Hodgkin aux differents stades evolutifs.  Aucune complication neurologique ne fut observe chez les malades attaints de Hodgkin. Ia moitie des enfa...

Syndrome de la queue de cheval. A propos de 4 cas.  Les auteurs rapportent quatre observations cliniques concernat des malades dont les pre­miers symptomes se manifesterent par des al­gies longitemps considerees comme "sciatique·s".  L' etude neurologique de ces cas demontrait qu'en realite "les algies sciatiques" n'etaient que des signes mono ou pluri-radiculaires en rapport avec un syndrome...

Photocatalytic reduction of carbon dioxide has been investigated on three different titania catalysts (two commercial titania, De Gussa P-25 and UV-100 Hombikat and another catalyst prepared by sol-gel method under reverse micelle environment) dispersed in aqueous alkaline medium under irradiation in visible region (300-700 nm) from Hg lamp. The catalysts have been characterized by XRD, diffuse...

Nanowires have great potential as building blocks for nanoscale electrical and optoelectronic devices. The difficulty in achieving functional and hierarchical nanowire structures poses an obstacle to realization of practical applications. While post-growth techniques such as fluidic alignment might be one solution, selfassembled structures during growth such as branches are promising for functi...

C media, particularly blogs, can help companies increase the visibility of their products without spending millions of dollars in advertising. Although a number of companies realize the potential of blogs and encourage their employees to blog, a good chunk of them are skeptical about losing control over this new media. Companies fear that employees may write negative things about them and that ...
