Lecture content

The lecture " Industrielle Verfahren der Arzneiformung " is part of the module " Pharmazeutische Verfahrenstechnik", which is held in cooperation with the Institute of Bioprocess Engineering and the Institute of Pharmaceutical Technology and Biopharmacy. An overview of the handling and manufacturing processes of various dosage forms in the pharmaceutical industry will be presented. Special emphasis will be placed on the fundamentals of the machinery and processes used. The lecture is held in german on a biweekly basis.

The lecture is structured as follows:

• Basic aspects and introduction to the pharmaceutical industry.

• Liquid forms (sterility, filling, disperse systems)
• Semi-solid forms
• Solid forms (particle size, granulation, extrusion, tableting, packaging)
• Special processes in the pharmaceutical industry

Module content

In this module, the basic working principle of batteries, the basic structure of battery systems, and their individual production steps are presented in detail. Not only established, but also novel battery systems and process technologies are discussed. In particular, process engineering principles concerning electrode production, system technology in electrode and cell production, and the different types of electrodes and cell structures are considered. Furthermore, their manufacturing process, the relationship between process and resulting product quality aspects, as well as diagnostic methods along the value chain, are discussed. Based on this content, students are introduced to the entire process chain of battery cell production and the influence of production technology on battery cell performance. The content taught is deepened in exercises accompanying the lectures, and the knowledge acquired is applied to practical problems

• Hydrogen economy
• Power and Hydrogen Generation
• Hydrogen Conversion
• Hydrogen storage and transportation
• Hydrogen Usage (e.g. Steel industry, fabric transformation, fuel cells in different applications)

Lecture contents

The lecture " Hybrid modeling and dynamic simulation of single and interconnected solid processes" is part of the module "Process simulation" and provides an overview of the various simulation and AI-supported control and modeling approaches for process engineering processes and process chains. Classical numerical methods such as population balance and flow diagram simulation methods, but above all the methods of machine learning, which are increasingly coming to the fore in the course of digitalization, are taught as basics.

The lecture is structured as follows:

• Overview of various modeling methods in particle technology
• Population balances methods
• Flow sheet simulation methods
• Methods of machine learning

Part of the module "Process Simulation" is also a practical course in which, in addition to the flow sheet simulation of solid processes, process modeling using machine learning algorithms is practiced in group work under supervison.

Die Vorlesung „Materialien und Prozesse für moderne Batteriesysteme“ ist ein Bestandteil des Moduls „Neue Technologien“ und findet als Blockveranstaltung jedes Sommersemester statt. Diese Vorlesung gibt eine Einführung über die verwendeten Materialien in modernen Batteriesystemen mit ihren wichtigsten Eigenschaften, sowie in die Prozesskette zur Herstellung einzelner Batteriekomponenten und deren Zusammenbau zu Zellen. Ein starker Fokus liegt dabei auf Lithium-Ionen-Batterien.

Vorlesungsinhalt

Der erste Teil der Vorlesung behandelt die Grundlagen der Elektrochemie und die Definitionen der wichtigsten Batterietypen mit ihren Eigenschaften und Leistungsparametern. Anschließend werden die Hauptkomponenten (Elektrolyt, Kathode, Anode, Separator) von Lithium-Ionen-Batterien vorgestellt, wobei der Schwerpunkt auf den zugrundeliegenden Materialien, ihren Eigenschaften und ihrer allgemeinen Synthese liegt. Die Vorlesung bietet zudem einen Einblick in die wichtigsten elektrochemischen Untersuchungsmethoden, sowie einen Ausblick auf mögliche zukünftige Batteriesysteme, wobei die Vor- und Nachteile im Vergleich zu Lithium-Ionen-Batterien diskutiert werden.

Im zweiten Teil der Vorlesung steht die gesamte Prozesskette vom Material bis zur fertigen Batteriezelle im Fokus. Die einzelnen Prozessschritte werden mit ihren wesentlichen Einflussparametern und den notwendigen Maschinen ausführlich diskutiert, wobei die Vor- und Nachteile von Prozessvariationen bewertet werden. Von besonderer Bedeutung sind die Prozess-Struktur-Eigenschaftsbeziehungen, die den Einfluss der Prozessierung auf die resultierenden Strukturen und die Korrelation zwischen Gefügeeigenschaften und der endgültigen Zellleistung definieren. Darüber hinaus werden wichtige, aktuelle Trends wie der Einsatz von Festkörperelektrolyten und deren Auswirkungen und Anforderungen an die Prozesskette diskutiert.
