SFB 445:  Nano Particles from the Gasphase: Formation, Structure, Properties

• Subject Area: Thermal Engineering/Process Engineering ; Computer Science, Systems and Electrical Engineering
• Term: from 1999 to 2010
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5483024

Nano-particles are a segment of nanotechnology. Nano-particles from the gasphase is a further restriction of the topic focussing it on the gasphase as the formation and transport space. Nano-particles have a reduced size in all three dimensions compared to bulk materials resulting in interesting physical an chemical properties.
The basic gool of the collaborative research centre is to study the formation of nano-particles from the gas phase by experiments, computersimulation, and modelling, to characterize the particles due to morphology and physico-chemical behaviour and to determine the interrelation between particle structure and particle properties. To reach such gools the collaborative research centre combines the experiences of various research groups from physics, chemistry, and engineering, which have relevant knowledge in theory and experiment and which fulfill the instrument and device requirements. The research works are concentrated on a limited number of materials being typical for various substances, such as the nano-ceramics TiN and TiC, or the semiconductors PbS and SnO2, which are known to have potential for practical usage as sensors and in optics. From the magnetic materials, the oxides of the iron metals (Fe, Co, Ni) are of interest for data storage and in liquid suspension as ferro-fluids. In the metal group, Pt is still an important material for catalytic application.
The collaborative research centre has structured his research programme according to the following project areas:
-- particle formation,
-- structure property relations,
-- applications.
