Characterisation of precipitation upon cooling of an AA2618 Al-Cu-Mg alloy

Jean-Marie Drezet, Nicolas Paul Henry Chobaut

The precipitation of an AA2618 Al-Cu-Mg alloy is monitored during isothermal holdings and continuous coolings. The Time-Temperature-Property and Continuous-Cooling-Precipitation diagrams of AA2618 are obtained using in-situ resistivity and differential sca ...

Ligand-Protein Affinity Studies Using Long-Lived States of Fluorine-19 Nuclei

Geoffrey Bodenhausen, Daniele Mammoli, Roberto Buratto, Estel Canet Martinez

The lifetimes T-LLS of long-lived states or T-LLC of long-lived coherences can be used for the accurate determination of dissociation constants of weak protein ligand complexes. The remarkable contrast between signals derived from LLS or LLC in free and bo ...

Predictive Models for Thermal Stability and Explosive Properties of Chemicals from Molecular Structure

Nadia Baati

Industrial chemical processes may involve thermal risks as most of the reactions performed are exothermic, the chemicals used are often thermally unstable, and the operating conditions are set to induce high conversion and throughput. Besides the reactive ...

Development of Stapling Methods by Selective Side Chain Modifications of Bioactive Peptides

Christopher Matthew Bandeli Kourra

Cyclic peptide therapeutics fill the gap between small molecules (5000 Da) as a separate class of drugs, combining the advantages of both in terms of high selectivity, bioavailability, synthetic accessibility and low toxicity. Howe ...

Curing kinetics and thermomechanical properties of latent epoxy/carbon fiber composites

Jan-Anders Edvin Maansson, Véronique Michaud, Pierre-Etienne Bourban, Sara Dalle Vacche

In this work, resins based on diglycidyl ether of bisphenol A (DGEBA) epoxy and a latent hardener, dicyandiamide (DICY), as well as carbon fiber (CF) composites based on them, were prepared with three commercial accelerators: a methylene bis (phenyl dimeth ...

Predictive Models for Thermal Behavior of Chemicals with Quantitative Structure-Property Relationships

Thierry Meyer, Francis Stoessel, Nadia Baati, Annik Nanchen

Most processes in the chemical industry involve potentially hazardous steps. It is thus of critical importance to perform risk assessments and to know the thermal behavior of the chemicals at stake. A widely used thermal analysis, differential scanning cal ...

Pozzolanic reactivity of low grade kaolinitic clays: Influence of calcination temperature and impact of calcination products on OPC hydration

Karen Scrivener

The influence of thermal activation temperature in the pozzolanic reactivity of low grade kaolinitic clay and the impact of calcination products in OPC hydration are assessed in this paper. The raw material, with approximately 40% kaolinite and 40% of 2:1 ...

Impact of Annealing on the Early Hydration of Tricalcium Silicate

Karen Scrivener, Marco Cantoni, Amélie Bazzoni

It was recently proposed that the induction period observed during the hydration of tricalcium silicate could be explained by the build-up of ions in solution. Due to the importance of defects in this mechanism, this work describes the effect of different ...

Understanding the Filler Effect on the Nucleation and Growth of C-S-H

Karen Scrivener, Elise Marie Jeanne Berodier

The filler effect, due to the physical presence of mineral additions in cement, is mainly known to accelerate the hydration of the clinker component. Previously, this was attributed to the surface of the filler providing nucleation sites for C-S-H as there ...

Thermal Behavior of Methylammonium Lead-Trihalide Perovskite Photovoltaic Light Harvesters

Michael Graetzel, Mohammad Khaja Nazeeruddin, Peng Gao, Peng Gao, Amalie Dualeh

Recently organicinorganic hybrid perovskites have attracted attention as light harvesting materials in mesoscopic cells. While a considerable number of deposition and formation methods have been reported for the perovskite crystalline material, most involv ...

Identification of the mechanisms responsible for static strain ageing in heavily drawn pearlitic steel wires

Daniele Mari

The microstructural changes occurring during drawing and ageing in pearlitic steel wires have been studied using the thermoelectric power (TEP) measurements combined with atom probe tomography (APT) and differential scanning calorimetry (DSC). APT analysis ...

Pressure-induced transformations in LiCl-H2O at 77 K

Livia Eleonora Bove Kado

A systematic study of the properties of high-density amorphous ice (HDA) in the presence of increasing amounts of salt is missing, especially because it is challenging to avoid ice crystallization upon cooling the pressurized liquid. In order to be able to ...
