The applicants are involved in highly competitive research in diverse fields of study. These areas of investigation include life sciences, biotechnology, nanotechnology, and environmental science. This NSERC Research Tools and Instruments grant proposal is in response to the current need expressed by the applicants to have access to a reliable tabletop ultracentrifuge that allows the processing of small volume samples (i.e. 1-2ml). This piece of equipment is essential for several aspects of the applicants' research. For example, the preparation of extracts from cells, a key step in several projects spearheaded by some of the applicants, requires centrifugation at a very high speed (over 150 000 x g!) that is only possible with the help of an ultracentrifuge. Other applicants require an ultracentrifuge to purify small amounts of environmental samples, or to separate nanoparticles according to their size. The instrument that the applicants are requesting is the Beckman Optima Max ultracentrifuge. This piece of equipment is small enough to be placed on a table or even on a cart. Considering the large number of expected users (this proposal involves 11 researchers!), the fact that this ultracentrifuge can be relatively easily moved from one laboratory to another is a major advantage. This ultracentrifuge also allows for 10 user programs, meaning that 10 research teams will be able to save their own ultracentrifugation settings, a big advantage in a multiuser environment. This Beckman Optima Max ultracentrifuge will have a major impact on the research programs of over 10 Laurentian University research teams, including dozens of graduate and undergraduate students.

申请人在不同的研究领域参与了竞争激烈的研究。这些研究领域包括生命科学、生物技术、纳米技术和环境科学。该NSERC研究工具和仪器拨款提案是为了响应申请人目前表达的需要，即获得可靠的台式超离心机，允许处理小体积样品（即1-2ml）。这台设备对申请人的研究的几个方面都是必不可少的。例如，从细胞中提取提取物的制备，是由一些申请人带头的几个项目的关键步骤，需要非常高速的离心（超过150000 x g!），这只有在超离心机的帮助下才能实现。其他申请者需要一个超离心机来净化少量的环境样品，或者根据它们的大小分离纳米颗粒。申请人要求的仪器是贝克曼Optima Max超离心机。这个设备很小，可以放在桌子上，甚至可以放在手推车上。考虑到大量的预期用户（该提案涉及11名研究人员！），这种超离心机可以相对容易地从一个实验室转移到另一个实验室，这是一个主要优势。这种超离心机还允许10个用户程序，这意味着10个研究团队将能够保存他们自己的超离心设置，这在多用户环境中是一个很大的优势。这台贝克曼Optima Max超离心机将对劳伦森大学10多个研究团队的研究项目产生重大影响，其中包括数十名研究生和本科生。
