"Spicy world of NanoScience"
« La croissance phénoménale des produits nanotechnologiques soulève des inquiétudes quant à l’exposition humaine aux nanoparticules ainsi produites, lesquelles peuvent poser des risques pour la santé et la sécurité des travailleurs. Outre l’élimination à la source ou la diminution de l’exposition, la ventilation, locale ou générale, et la protection personnelle, en particulier respiratoire, sont les moyens de contrôle à privilégier dans ce contexte. Or, le bon fonctionnement de ces procédés repose notamment sur l’efficacité des filtres. Ce projet vise la mise au point d’une méthode pour caractériser les filtres des appareils de protection respiratoire et des systèmes de ventilation à des débits d’air différents. La méthode ainsi élaborée pourrait également s’appliquer à l’évaluation de l’efficacité des vêtements de protection poreux. Les résultats de cette étude permettront de mieux protéger les travailleurs exposés aux nanoparticules et contribueront au développement d’une expertise actuellement inexistante au Canada. »
« In spite of very low mass concentration, the number of nanoparticles (NPs) in the environment can be very high. Thus, human exposure to NPs could be significantly more dangerous to human health than exposure to larger particles. The Scientific Committee on Emerging and Newly Identified Health Risk (SCENIHR, 2006) indicated that there could be roughly 10,000 to 20,000 NPs in the air of a normal room and 50,000 and 100,000 NPs per cubic cm in wooded and urban areas, respectively. »

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.
There is only one important assumption: you have to be interested in nano!
