A Fast Detector for Measurement of Phase Transitions in Calcium Phosphate Based Biomaterials

在伊士曼牙科研究所，我们最近购买了一台衍射仪，用于研究晶体材料，特别是陶瓷和玻璃。进一步的购买使我们能够安装一个高温台，以观察材料如何在高温下结晶和熔化。然而，我们拥有的高分辨率探测器只能非常缓慢地收集数据，而我们感兴趣的物理过程可能会非常迅速地发生。因此，在本提案中，我们要求提供资金，以购买一个新的非常高速的探测器，以配合仪器。这不仅使我们能够研究玻璃熔化等现象，而且更普遍的是，我们将能够为英国生物材料社区运行该设施，因为数据收集时间将非常短（高质量的全模式数据可以在几分钟内收集，而不是目前的设置，我们收集数据过夜。我们目前正在为英国的一些团体运行样品，并希望扩大这种访问。因此，我们将能够调查一些新材料中的有趣现象，以更好地了解它们的稳定性和反应性，同时也能够为英国各地的用户收集高质量的数据。

At the Eastman Dental Institute, we have recently acquired a diffractometer to investigate crystalline materials, and in particular, ceramics and glasses. A further purchase has allowed us to install a high temperature stage to look at how materials crystallise and melt at high temperature. However the detector we have whilst high resolution will only collect data very slowly and the physical processes we are interested in may occur quite rapidly. Thus in this proposal we have asked for funding to purchase a new very high speed detector to go with the instrument. Not only will this allow us to investigate phenomena such as melting in glasses, but also more generally, we will be able to run the facility for the UK biomaterials community as data collection times will be extremely short (high quality full pattern data can be collected in a few minutes as opposed to the current setup where we collect data overnight. We do currently run samples for a number of groups in the UK and hope to expand this access.Thus we will be able to investigate interesting phenomena in some novel materials to give a greater understanding of their stability and reactivity but also be able to collect high quality data for users throughout the UK
