Structure, Oxygen Content and Electric Properties of Titanium Nitride Electrodes in TiNx/La:HfO2/TiNx Stacks Grown by PEALD on SiO2/Si
Philippe Buffat, Elena Suvorova Buffat
This work reports experimental results of the quantitative determination of oxygen and band gap measurement in the TiNx electrodes in planar TiNx top/La:HfO2/TiNx bottom MIM stacks obtained by plasma enhanced atomic layer deposition on SiO2. Methodological ...
2022Quantitative Analysis of Nanorough Hydrogenated Si(111) Surfaces through Vibrational Spectral Assignment by Periodic DFT Calculations br
Christophe Ballif, Stefaan De Wolf, Jakub Holovsky
In this work, we use periodic density functional theory(periodic DFT) to rigorously assign vibrational spectra measured on nanorough wet-processed hydrogenated Si(111) surfaces. We compare Si(111)-(1x1) surfaces etched by dilute HF and NH4F, featuring two ...
AMER CHEMICAL SOC2022Magnetic force microscopy contrast formation and field sensitivity
The magnetic force microscope (MFM) is an established experimental tool for imaging stray fields with high spatial resolution and sensitivity. The MFM contrast can however contain contributions from the sample topography, variations in the surface Kelvin p ...
2022Design and fabrication of an aerosol collector for infrared spectroscopy analysis
Particulate matter (PM) pollution causes adverse health effects and millions of deaths each year. PM or aerosol, is difficult to characterize because of its wide range of particle sizes, constituents (various organic and inorganic compounds), concentration ...
EPFL2021Inkjet-Printed Carbon Nanotube Electrodes Modified with Dimer-captosuccinic Acid-Capped Fe3O4 Nanoparticles on Reduced Graphene Oxide Nanosheets for Single-Drop Determination of Trifluoperazine
Hubert Girault, Andreas Stephan Lesch, Milica Jovic
Here we report the design of a disposable single-drop voltammetric sensor for the quantitative determination of antipsy-chotic drug trifluoperazine (TFP). The sensor was build using inkjet-printed carbon nanotube (CNT) electrodes which were modified with d ...
2020Environmental Flows Determination and Monitoring with Hydraulic Habitat Models-Pushing the Boundaries of Habitat Models Application
Mikolaj Stanislaw Adamczyk, Piotr Parasiewicz
Hydraulic habitat simulation models were designed for the quantitative determination of environmental flows that consider the needs of aquatic fauna in rivers and streams. In the past 50 years, the modeling techniques were significantly developed, but expe ...
2019Decisive role of nuclear quantum effects on surface mediated water dissociation at finite temperature
Michele Ceriotti, Mariana Rossi Carvalho
Water molecules adsorbed on inorganic substrates play an important role in several technological applications. In the presence of light atoms in adsorbates, nuclear quantum effects (NQEs) influence the structural stability and the dynamical properties of t ...
2018Advanced characterization methods for self-assembled organization on nanoparticles
The complex organizations of amino acid residues on protein surfaces give rise to a wide space of functions for proteins. Great efforts are devoted in biology to understand such structure-property relationships. Many advanced characterization techniques ha ...
EPFL2018Assessment of Image Quality Requirements in Magnetic Resonance Imaging for Quantitative Brain Morphometry
Structural T1-weighted magnetic resonance imaging (MRI) provides sufficient anatomical details to measure and track changes in volumes of brain structures. The volumes of brain structures and changes in them can be used to study the effects of disease, tre ...
EPFL2016Crystalline and Soft Materials Based on Dative Boron-Nitrogen Bonds
The thesis describes the utilization of dative boron-nitrogen bond is used for the construction of new materials. In chapter 2.1, the synthesis of new organogels based on bisimidazolyl ligands and diboronate esters is described. Gels with a critical gel co ...
