Description

This lecture covers fundamental concepts in thermodynamics, focusing on the first principle and its applications. It begins with an introduction to characteristic variables of studied systems, emphasizing the relationship between pressure and depth. The instructor discusses Archimedes' principle and the concept of intensive and extensive properties. The lecture then delves into equations of state, partial and total differentials, and their significance in thermodynamic systems. The instructor explains the importance of defining the system and its boundaries, distinguishing between isolated, closed, and open systems. Various types of thermodynamic transformations are introduced, including isothermal, isobaric, and adiabatic processes. The lecture culminates in a detailed explanation of the first principle of thermodynamics, which states that energy cannot be created or destroyed, only transformed. The instructor illustrates these concepts with practical examples, such as the behavior of gases in pistons and the implications of energy exchanges in thermodynamic systems. Overall, the lecture provides a comprehensive overview of thermodynamic principles and their relevance in physical systems.

Jean-Philippe Ansermet

Jean-Philippe Ansermet was born March 1, 1957 in Lausanne (legal origin Vaumarcus, NE). He obtained a diploma as physics engineer of EPFL in 1980. He went on to get a PhD from the University of Illinois at Urbana-Champaign where, from 1985 to 1987, he persued as post-doc with Prof. Slichter his research on catalysis by solid state NMR studies of molecules bound to the surface of catalysts. From 1987 to 1992 he worked at the materials research center of Ciba-Geigy, on polymers for microelectronics, composites, dielectrics and organic charge transfer complexes. In March 1992, as professor of experimental physics, he developed a laboratory on the theme of nanostructured materials and turned full professor in 1995. Since 1992, he teaches classical mechanics, first to future engineering students, since 2004 to physics majors. Since 2000, he teaches thermodynamics also, to the same group of students. He offers a graduate course in spintronics, and another on spin dynamics. His research activities concern the fabrication and properties of magnetic nanostructures produced by electrodeposition. His involvement since the early days of spintronics have allowed him to gain recognition for his work on giant magnetoresistance (CPP-GMR), magnetic relaxation of single nanostructures, and was among the leading groups demonstrating magnetization reversal by spin-polarized currents. Furthermore, his group uses nuclear magnetic resonance , on the one hand as means of investigation of surfaces and electrodes, on the other hand, as a local probe of the electronic properties of complex ferromagnetic oxides.

Cécile Hébert

Cécile Hébert was born in France in 1970. She obtained her Ingeneer degree (physics) and her PhD degree (design of a new energy filter for transmission electron microscopy, under the direction of Prof. B. Jouffrey) at the Ecole Centrale in Paris. As a post doc with Prof. P. Schattschneider, she was working on the calculation of the fine structure of ionisation edges in EELS. As a research assistant at the Vienna University of Technology, she was one of the main participant to the CHIRALTEM project dealing with the measurement of magnetic circular dichroism in the electron microscope.
