Masterarbeit aus dem Jahr 2013 im Fachbereich Physik - Optik, Note: 1.3, Ludwig-Maximilians-Universität München, Sprache: Deutsch, Abstract: With the prospect of high-intensity isolated attosecond pulses XUV pump-XUV probe spectroscopy as well as novel methods for controlling atomic-scale currents seem feasible paving the way for new physical, chemical, biological, and medical applications such as attosecond X-ray diffraction, non-invasive imaging and cancer therapy. To reach these ambitious goals, optical parametric chirped pulse amplifcation (OPCPA) in combination with high harmonic generation (HHG) seems like a promising route. But this approach puts stringent demands on the pump laser driving it. To overcome these challenges Yb:YAG as active laser medium in a thin-disk geometry is often used offering a lot of favourable properties for high power applications with excellent beam quality. Yb:Yag can be pumped at either 940 nm or, more recently, since the advent of Volume-Bragg-Grating stabilized diodes, at its Zero-Phonon-Line with a wavelength of 969 nm. These two wavelengths excite different transitions in the 5 F 1/2 electronic shell each exhibiting its own assets and drawbacks. This thesis will focus on a comparison between them. A theoretical model of the conditions in the pumped thin-disk is created. Absorption of the pump light is calculated numerically. Amplified spontaneous emission and thermal effects are considered, too. The structure of the 5 F 1/2 energy manifold is accounted for thus allowing predictions for two different pumping wavelengths at 940 nm and 969 nm. To gauge the accuracy of the model the numerical calculations are compared with measurements conducted at LMUs newly-built Laboratory for Extreme Photonics. A regenerative amplifer is set up to quantify the roundtrip gain at different pumping powers and wavelengths. The temperature of the pumped disk and its deformations as well as the single pass gain are measured, too. All measurements are in reasonable agreement with theory. After the motivation for this work some basic properties of lasers are introduced. In chapter 3 the basics of thermodynamics and its application to laser gain media, especially Yb:YAG, will be covered. The previous considerations will be numerically applied to the case of a thin-disk regenerative amplifer in the 4. chapter. Additional aspects, like its cavity and nonlinear effects, will be considered, too. Chap. 5 will give a description of the experimental methods and setups used to check the numerical predictions while the raw measured data and its interpratation are stated chap. 6 and 7

Catalysis to produce hydrogen

The share market of hydrogen is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. Hydrogen production by using metal catalyst will need to increase with this growing market. However, some carbon is deposited on the catalyst but there was a window of operation where the deposited carbon did not have too great an effect on hydrogen production under different conditions. Carbon formation deactivates the catalyst, resulting in short life cycles. In order to improve process performance, in particular minimizing catalyst deactivation caused by carbon formation and maximizing the yield of hydrogen product, the addition of the promoters to catalyst is the most familiar method. The book is focused on the art of the promoters application on metal catalyst for hydrogen production from the methane steam reforming process at high pressure and the steam iron process over promoted Fe-oxide based catalyst.

Manchmal ähnelt die Zeitgeist-Analyse einer simplen Aufwärts-Abwärts-Betra- tung: Es gibt bei bestimmten Themen Hochkonjunkturen und Rezessionen. Zu m- chen Zeiten verschwinden diese Themen, gelten als fad und unzeitgemäß, lassen sich in den Zeitungsspalten und Zeitschriften-Feuilletons nicht mehr finden, werden in politischen Ankündigungen und Programmen ignoriert; zu anderen Zeiten gelten sie als brisante, aktuelle Themen, werden politisch in Kommissionen und Gutachten zelebriert, intellektuell hin- und hergewendet und publizistisch erfolgreich ver- kert, und in den Medien werden Sonderseiten und Schwerpunktserien eingerichtet, um den Informations-, Diskussions- und Vorurteilsbedarf zu befriedigen. Die B- dung ist ein typischer Fall für dieses Auf und Ab. Die meiste Zeit geht es um Modethemen, um organisatorische oder dienstrec- liche Details, um Aufsehen erregende Ereignisse, an denen sich die Gemüter erh- zen. Aber in einer turbulenten Gesellschaft muss auch die Grundfrage immer wieder einmal gestellt und jeweils den Umständen angemessen beantwortet werden: Was denn das Ziel der Bildungseinrichtungen sei? Was Bildung überhaupt sei? Wofür eine Schule oder eine Universität zu bilden hätte? Wie dies am besten geschehen könne? Wie gut die Ziele erreicht würden? Wie der Bildungserfolg überprüfbar sei? Die Fragen stellen eine grundlegende Herausforderung für alle dar, die im B- dungsgeschehen arbeiten. Man kann sie ignorieren und stattdessen über Stund- zahlen und Lehrdeputate reden. Man kann sie individualisieren, zu einer Sache des jeweils einzelnen Lehrenden machen und diese als Sündenböcke gebrauchen, wenn 1 irgendetwas schief geht.

The planar solid-oxide fuel cells (PSOFCs) have emerged as one of the promising candidates for future energy system because of their high energy efficiency, fuel flexibility, zero emission, modularity and high tolerance to the fuel impurities. However, for large-scale commercialization of the PSOFC technology, there is a strong need of developing a reliable and highly efficient PSOFC power system. Development of such a reliable PSOFC based power system requires knowledge of the several feedback effects from the power electronics system and the application loads that may impact the PSOFC stack and the system as a whole. Therefore, it is important to develop analytical methodologies to investigate and mitigate the effects of these electrical feedbacks on the performance of PSOFC systems. On the whole, the dissertation focuses on i) the modeling and development of an effective PSOFC power- system design and system interaction analyses, ii) cost-constrained PES topology design for PSOFCS and iii) the design of cost effective optimal controller and controlling strategy for mitigation of electrical impacts with higher system efficiency.
