Characterization method of dielectric properties of free falling drops in a microwave processing cavity and its application in microwave internal gelation

Manuel Alexandre Pouchon, Sébastien Vaucher, Cédric Cozzo

Microwave internal gelation (MIG) is a chemical process proposed for the production of nuclear particle fuel. The internal gelation reaction is triggered by a temperature increase of aqueous droplets falling by gravity by means of non-contact microwave hea ...

Synthetic polyubiquitinated α-Synuclein reveals important insights into the roles of the ubiquitin chain in regulating its pathophysiology

Hilal Lashuel, Bruno Claude Daniel Fauvet, Mirva Hejjaoui, Mahmood Haj Yahya

Ubiquitination regulates, via different modes of modifications, a variety of biological processes, and aberrations in the process have been implicated in the pathogenesis of several neurodegenerative diseases. However, our ability to dissect the pathophysi ...

Quantification of "Fuzzy" Chemical Concepts: A Computational Perspective

Matthew Wodrich, Jérôme Florian Gonthier

Chemists recurrently utilize "fuzzy'' chemical concepts (e.g. atomic charges, the chemical bond, strain, aromaticity, branching, etc.), which lack unique quantitative assessments but, nonetheless, are frequently employed as tools for understanding the intr ...

Thermodynamics of continuous media with electromagnetic fields

Jean-Philippe Ansermet, Sylvain Bréchet, François Reuse

The thermodynamics of an electrically charged, multicomponent continuous medium with electromagnetic fields is analysed in the non-relativistic limit. Applying locally the first and second law of thermodynamics and Maxwell’s equations for a linear theory o ...

Semiclassical approach to ground-state properties of hard-core bosons in two dimensions

Frédéric Mila, Tommaso Coletta, Nicolas Laflorencie

Motivated by some inconsistencies in the way quantum fluctuations are included beyond the classical treatment of hard-core bosons on a lattice in the recent literature, we revisit the large-S semiclassical approach to hard-core bosons on the square lattice ...

Ultrafast photodoping and effective Fermi-Dirac distribution of the Dirac particles in Bi2Se3

Klaus Kern, Marco Grioni, Helmuth Berger, Philippe Bugnon, Alberto Crepaldi

We exploit time- and angle-resolved photoemission spectroscopy to determine the evolution of the out-of-equilibrium electronic structure of the topological insulator Bi2Se3. The response of the Fermi-Dirac distribution to ultrashort IR laser pulses has bee ...

Predicting Concentrations of Organic Chemicals in Fish by Using Toxicokinetic Models

Kristin Schirmer

Quantification of chemical toxicity continues to be generally based on measured external concentrations. Yet, internal chemical concentrations have been suggested to be a more suitable parameter. To better understand the relationship between the external a ...

Self-assembled photosystem-I biophotovoltaics on nanostructured TiO2 and ZnO

Michael Graetzel, Mohammad Khaja Nazeeruddin

The abundant pigment-protein membrane complex photosystem-I (PS-I) is at the heart of the Earth's energy cycle. It is the central molecule in the "Z-scheme'' of photosynthesis, converting sunlight into the chemical energy of life. Commandeering this intric ...

Phase Gradient Estimation Techniques in Fringe Analysis

Rajshekhar Gannavarpu

The thesis introduces novel techniques in the field of fringe analysis for direct estimation of phase gradients or derivatives. A pseudo Wigner-Ville distribution based method is proposed to reliably estimate the phase derivatives from a single fringe patt ...

Soudure par interdiffusion dans les systèmes Au-In et In-Ni

Léa Deillon

Hermiticity is an essential requirement of a MEMS package for a device to work properly. Hermeticity also must be preserved during the operations following packaging, during which the package bond should not remelt. Bonding temperature is limited however t ...
