纳米结构的多孔表面层和涂层具有非常有前途的应用，例如作为气体传感器以及在催化和光电器件中。控制和可再现的工艺条件的指导方针需要派生的纳米粒子生产的基础技术，成功的制造工艺。特别是非常有前途的新发展，现场气相混合的多火焰喷雾只是知之甚少。喷雾火焰混合相对于物种和温度的成功预测可以为定义的纳米界面创建有效的处理工具，例如用于许多类型的电子传输/存储问题（例如水分解，太阳能电池）的异质结。该项目的主要目的是确定合适的工艺条件，通过采用火焰喷雾热解过程与随后的纳米粒子沉积控制制造纳米结构涂层和层的试样。实验数据采集（Uni不莱梅）的发展和验证的数值模型（Uni Blumenau）表示的纳米粒子的生产和沉积过程的目的是工艺定制和规模扩大的研究。火焰和喷雾关键参数的现场实验过程监测将基于激光诊断测量。BRAGECRIM框架内的ManuNanoDep项目的主要目标可以概括为： 导出用于制造定制纳米结构涂层的合适工艺条件。 为过程监测（过程计量学）开发适当的现场诊断技术。 纳米结构沉积制造的描述和比例缩放的组合集成工艺模型的开发。

Nanostructured porous surface layers and coatings have very promising applications e.g. as gas sensor as well as in catalysis and optoelectronic devices. Guidelines for controlled and reproducible process conditions need to be derived for bringing the basic technology of nanoparticle production into successful manufacturing processes. Especially the very promising new development of in situ gas phase mixing of multiple flame sprays is only poorly understood. The successful prediction of spray flame mixing with respect to species and temperature can create an efficient processing tool for defined nano-interfaces such as heterojunctions for many types of electron transports / storage issues (e.g. water splitting, solar cells). The main aim of the project is the determination of the suitable process conditions for controlled manufacturing of nanostructured coatings and layers on specimen by employing the flame spray pyrolysis process with subsequent nanoparticle deposition. Experimental data acquisition (Uni Bremen) for the development and validation of numerical models (Uni Blumenau) is employed to represent the nanoparticle production and deposition processes aiming for process tailoring and scale-up studies. In situ experimental process monitoring of flame and spray key parameters will be based on laser diagnostic measurements.The main objectives of the project ManuNanoDep within the BRAGECRIM framework may be summarized as:- Derivation of suitable process conditions for manufacturing of tailored nanostructured coatings.- Development of suitable in situ diagnostic techniques for process monitoring (process metrology).- Development of combined integral process models for description and scaling of nanostructured deposition manufacturing.
