Upgrade to sputter coater for field emission SEM

我们要求紧急升级我们的涂层仪器，用于制备样品，使用我们的场发射扫描电子显微镜（FE-SEM）进行分析，该仪器最近由麦克马斯特大学购买。该工具在制备生物材料、聚合物、半导体和绝缘体等广泛应用的样品中是必不可少的组成部分，以便提供最高质量的图像，而不会产生由当前涂布机产生的伪影，这些涂布机产生的涂层不足以用于高分辨率FE-SEM。应用领域包括能源相关材料、生物材料复合材料、聚合物纳米颗粒和微胶囊、光电材料和铁电材料。总体而言，所需的仪器将被许多学生（包括本科生和研究生），博士后研究员和研究人员使用。预计约有50个用户将从该仪器中受益，并将获得他们合成的样品的可靠结构信息。该仪器将被安置在麦克马斯特大学新成立的加拿大电子显微镜中心的布罗克豪斯材料研究所。

We are requesting an urgent upgrade to our coating instrument for the preparation of samples to be analysed using our Field Emission Scanning Electron Microscope (FE-SEM), recently purchased by McMaster University.  This tool is an essential component in the preparation of samples from an extremely broad range applications in biomaterials, polymers, semiconductors and insulators so as to provide images of the highest quality without the artifacts generated by the current coater, which produces coating layers that are inadequate for the high resolution FE-SEM. The areas of applications cover energy-related materials, biomaterial composites, polymer nanoparticles and microcapsules, optoelectronic materials and ferroelectric materials. Overall, the instrument required will be used by numerous students (including undergraduate and graduate students), postdoctoral fellows and researchers.  It is expected that approximately 50 users of the FE-SEM will benefit from this instrument and will obtain reliable structural information on the samples they have synthesized. This instrument will be located at the Brockhouse Institute for Materials Research in the new Canadian Centre for Electron Microscopy at McMaster University.
