Background
Energy technology is one of the major challenges of the
21st century
Solution: The NanoEnergieTechnikZentrum
NETZ is an application-focused research project
Aim: Develop materials and processes which allow nanotechnology to be used in industry21st century
Nanotechnology can significantly contribute in this field
The link between nanoscience and energy technology is based
on one fundamental fact: Conversion of energy takes place at
interfaces and surfaces and therefore on the nanometer scale
Multifunctional materials for energy technology can be designed
Aim: Develop materials and processes which allow nanotechnology to be used in industry
Multifunctional materials for energy technology can be designed
based on principles and materials provided by nanotechnology
Main steps:
Cluster of nanoparticle synthesis reactors Flame reactor Hot-wall reactor Microwave plasma reactor
The availability gap
Main steps:
I. Develop processes for the synthesis of nanomaterials on an industrial scale
�A unique cluster of pilot-plant-scale gas-phase reactors for the synthesis of highly specific
nanoparticles has been installed at IUTA
�The reactors provide ample opportunities for in-situ measurements and sampling to fully
characterize the reaction processes and to provide information for the development and
validation of numerical simulation tools
So far: Insufficient research into the production of nanomaterials
in large volumes
���� Materials of interest are not available on practically validation of numerical simulation tools
II. Functionalization, dispersion, generation of hybrid materials
�Surface modification of synthesized particles is the key for the production of dispersions and
composite or hybrid materials
�Investigation if the interplay of nanoparticles, matrix materials, and dispersion strategies
���� Materials of interest are not available on practically
relevant scales
���� The suitability of nanomaterials for volume production
cannot be demonstrated
���� Industrial implementation is too risky for companies
���� Potential applications are not developed
The aim of the NanoEnergieTechnikZentrum (NETZ) is to III. Coating, immobilization, processing
�Generation of functional surfaces and volume elements
The aim of the NanoEnergieTechnikZentrum (NETZ) is to
overcome this deadlock
