Transition metal oxides (TMOs) are an extraordinary class of materials that have found wide applicability for a number of century-defining technologies (e.g. flat-panel display, capacitors and energy storage) mainly due to their dielectric properties and facilitated by chemical inertness. TMOs are also conceptually simple materials with crucially important properties, they can be formed by low-cost and naturally abundant metals in combination with oxygen, therefore offering commercially attractive materials solutions. Recently, TMOs have seen a surge in application demand and research interest, which revealed their fundamental complexity and yet-to-discover application opportunities. Doping, defect engineering, quantum confinement and extending to ternary or high entropy oxides can lead to new or improved properties and can create disruptive materials. However, to achieve a step change in application performance, manufacturing precision is required at scale, which motivates the production of TMOs materials with ever increasing precision as well as the necessity to establish scalable manufacturing processes. This project will deliver a platform to synthesize TMOs materials with nanoscale precision (down to sub-10 nm scales) and atomically controlled chemical composition. A cold microplasma reactor operated at atmospheric pressure is at the core of this manufacturing technology platform which relies on the most recent 21st century plasma technology developments. The synthesis of TMOs is carried out through the interactions of a cold atmospheric pressure microplasma with a solid metal feedstock in an oxygen-containing gas, contributing to reduce waste and leading to a sustainable, zero-loss and 'greener' manufacturing technology.

过渡金属氧化物（TMOS）是一种非凡类型的材料，发现广泛适用于许多世纪定义的技术（例如平板显示，电容器和能量存储），主要是由于它们的介电性能并由化学惰性促进。 TMOS在概念上也是具有至关重要的特性的概念上的简单材料，它们可以由低成本和自然丰富的金属与氧气结合使用，因此提供了商业上吸引人的材料解决方案。最近，TMO看到了应用需求和研究兴趣的激增，这揭示了他们的基本复杂性和尚未发现的应用程序机会。掺杂，缺陷工程，量子限制并扩展到三元或高熵氧化物可能会导致新的或改进的特性，并可能产生破坏性的材料。但是，为了实现应用程序性能的步骤变化，规模上需要制造精度，这激发了TMOS材料的生产，其精度越来越高以及建立可扩展制造过程的必要性。该项目将提供一个平台，以合成具有纳米级精度（降至低于10 nm尺度）的TMOS材料和原子控制的化学成分。在大气压力下运行的冷微质量反应堆是该制造技术平台的核心，该平台依靠最近21世纪的等离子体技术发展。 TMOS的合成是通过冷大气压微量质量与含氧气体中的固体金属原料的相互作用进行的，这有助于减少废物并导致可持续的零损坏和“绿色”制造技术。
