The electronic and thermodynamic properties of novel materials produced by aerodynamic levitation.

在高温下处理液体材料是常见的，并且对于技术材料的生产非常重要。日常生活中的例子包括钢铁和玻璃生产以及化学加工。然而，尽管如此，关于高温液体的基本性质，关于它们的化学结构如何产生它们的性质以及我们如何预测它们的行为，仍然存在许多问题。其他关键问题涉及一些材料如何以及何时形成玻璃而不是结晶固体，以及这种行为的根本原因是什么。在本提案中，我们希望开发一个系统，通过该系统，我们可以开始解决其中一些问题，并为新技术材料的生产提供新的见解。这项工作背后的核心原理是使用我们目前安装的空气动力悬浮系统来研究温度高达3000 K的液体。关键是所有这些研究都可以在没有物理遏制的情况下进行，以便材料不受坩埚和熔炉的污染。此外，我们最近表明，我们的系统，我们可以获得精确的加热和冷却的细磨样品的冷却速率高达~ 500 K/s，同时监测热力学性质。初步结果表明，我们有良好的控制生产的玻璃和玻璃陶瓷材料，我们希望研究他们的潜在用途。

The processing of liquid materials at high temperatures is commonplace and very important for the production of technological materials. Examples in everyday life include for example steel and glass production and chemical processing. However, despite this, there remain many questions regarding the fundamental nature of high temperature liquids with regards to how their chemical structure gives rise to their properties and how we can predict their behaviour. Other key issues concern how and when some materials form glasses rather than crystalline solids and what are the underlying reasons for this behaviour. In this proposal we wish to develop a system with which we can start to address some of these issues as well as providing new insights into the production of new technological materials. The core principle behind the work is to use our currently installed aerodynamic levitation system to study liquids at temperatures up to 3000K. The key is that all these studies can be carried out without physical containment so that the material remains uncontaminated by crucibles and furnaces. In addition, we have recently shown that with our system we can obtained precise heating and cooling of leviated samples with cooling rates upto ~ 500 K/s while monitoring thermodynamic properties. Preliminary results show taht we have fine control of the production of glasses and glass-ceramics - materials that we wish to study for their potential uses.
