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（TMO）是一类特殊的材料，主要由于其介电性能和化学惰性，已广泛应用于许多世纪定义技术（例如平板显示器，电容器和能量存储）。TMO也是概念上简单的材料，具有至关重要的特性，它们可以由低成本和天然丰富的金属与氧结合形成，因此提供了商业上有吸引力的材料解决方案。最近，TMO的应用需求和研究兴趣激增，这揭示了其基本的复杂性和尚未发现的应用机会。掺杂、缺陷工程、量子限制和扩展到三元或高熵氧化物可以导致新的或改进的性能，并可以创造破坏性的材料。然而，为了实现应用性能的阶跃变化，需要大规模的制造精度，这促使TMO材料的生产具有不断提高的精度以及建立可扩展的制造工艺的必要性。该项目将提供一个平台来合成具有纳米级精度（低至10 nm尺度）和原子控制化学成分的TMO材料。在大气压下操作的冷微等离子体反应器是该制造技术平台的核心，该制造技术平台依赖于最新的世纪等离子体技术发展。TMO的合成是通过冷大气压微等离子体与含氧气体中的固体金属原料的相互作用进行的，有助于减少浪费，并导致可持续，零损失和“绿色”的制造技术。
