Biomass Modelling: estimating thermodynamic properties from the elemental composition

François Maréchal, Guillaume Boissonnet, Emanuela Peduzzi

In the context of modelling biomass conversion processes, the accurate representation of biomass, which is a complex and highly variable material, is of crucial importance. This study provides a rather simple and flexible way to represent biomass, especial ...

Design of an Efficient High Power Electromagnetic Radiator using a Yagi-Uda Antenna Connected to a Switched Ocillator

We propose in this paper the use of a monopolar version of the Yagi-Uda antenna connected to a switched oscillator (SWO). At the resonance frequency, this antenna offers a higher impedance than, for example, a Half Impulse Radiating Antenna (HIRA), a helic ...

Revisiting Newton’s rings with a plasmonic optical flat for high-accuracy surface inspection

Olivier Martin, Xiaolong Wang, Jie Bian

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength corrugations on a reflective surface by simply placing on it a ...

Combined in situ synchrotron micro X-ray diffraction and high-speed imaging on rapidly heated and solidified Ti-48Al under additive manufacturing conditions

Helena Van Swygenhoven, Steven Van Petegem, Christian Leinenbach

An in situ method to study the behavior of alloys during rapid heating and cooling combining laser heating with synchrotron micro X-ray diffraction and high-speed imaging is presented. Near-spherical Ti-48Al specimens were melted using a laser-based heatin ...

Dissolution dynamic nuclear polarization of deuterated molecules enhanced by cross-polarization

Geoffrey Bodenhausen, Sami Jannin, Jonas Milani, Estel Canet Martinez, Daniel Abergel, Sina Marhabaie, Matthias Weller

We present novel means to hyperpolarize deuterium nuclei in (CD2)-C-13 groups at cryogenic temperatures. The method is based on cross-polarization from H-1 to C-13 and does not require any radio-frequency fields applied to the deuterium nuclei. After rapid ...

Multi-device studies of pedestal physics and confinement in the I-mode regime

Christian Gabriel Theiler, Alessandro Marinoni

This paper describes joint ITPA studies of the I-mode regime, which features an edge thermal barrier together with L-mode-like particle and impurity transport and no edge localized modes (ELMs). The regime has been demonstrated on the Alcator C-Mod, ASDEX ...

Contribution to the Chemistry of Borophosphonates and Imidazolin-2-imines

Justus Tönnemann

In the course of this thesis, two chemically very different topics are going to be discussed. The first part will cover the chemistry of borophosphonate and borophosphate cages, with regard to their application as building blocks for network structures or ...

Highly stretchable dielectric elastomer composites containing high volume fractions of silver nanoparticles

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

The dielectric permittivity (epsilon') of a polymeric material can be significantly increased when blended with conductive fillers at concentrations approaching the percolation threshold. However, reproducible synthesis of such composites is after decades ...

Modeling of Long-Term Multipactor Evolution in Microwave Components Including Dielectric Layers

Apostolos Sounas

Multipactor is a resonant vacuum discharge occurring in microwave components of satellite systems as well as in particle accelerators. Due to its undesirable effects, multipactor analysis constitutes a mandatory step in the design of modern satellite compo ...

Towards pre-dimensioning of natural gas networks on a web-platform

Gaëtan Cherix, Massimiliano Capezzali, Pablo Puerto, Mathias Franz Pernet

The MEU GIS-enabled web-platform has been developed in close collaboration with four Swiss cities: it enables detailed monitoring and planning for both energy demand and supply at individual building and neighborhood level (http://meu.epfl.ch). This web-pl ...
