Regenerative Energie
Nanosized particles were prepared by ultrasonic spray pyrolysis at the IME, RWTH Aachen University. Ultrasonic spray pyrolysis is a single step process mostly used for the generation of aerosol from a dilute aqueous metal salt solution, resulting in the production of metal particles with a narrow particle size distribution. The transformation of aerosol to particles contains: evaporation, precipitation from solution, thermal decomposition and sintering. The formed aerosol droplets are transported from ultrasonic chamber to the reactor. After the evaporation in gas atmosphere the particles were decomposed to a solid particle. The sintering of particles represents the final step of solid particle formation. The collection of particles was performed in an electrostatic field.
The Failure Modes and Effects Analysis (FMEA) is analytical methodology derived from Quality Management for analyzing potential reliability problems early in the development cycle where it is easier to take actions to overcome these issues. The main aim is detection and prevention of mistakes in system in order to minimize mistakes. The potential mistakes were analyzed using ultrasonic spray pyrolysis process for the synthesis of nanosized particles of silver. It is concluded that one potential can be used in order to eliminate the mistakes during the scale up. The behavior of metal nanoparticles concerning to the explosion potential was discussed.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)
© Lexxion Verlagsgesellschaft mbH (6/2025)
In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft
© Lexxion Verlagsgesellschaft mbH (6/2025)
This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
