Effect of surface modification of colloidal silica nanoparticles on the rigid amorphous fraction and mechanical properties of amorphous polyurethane-urea-silica nanocomposites

John Christopher Plummer, Nicolas Candau, Oguzhan Oguz, Stéphane Henri Florian Bernhard

Colloidal silica nanoparticles (NPs) modified with eight different silane coupling agents were incorporated into an amorphous poly(tetramethylene oxide)-based polyurethane-urea copolymer matrix at a concentration of 10 wt % (4.4 vol %) in order to investig ...

Fast real time and quantitative gas analysis method for the investigation of the CO2 reduction reaction mechanism

Andreas Züttel, Emanuele Moioli, Wen Luo, Robin Tobias Andreas Mutschler

We present a new fast real time and quantitative gas analysis method by means of mass spectrometry (MS), which has approximately an order of magnitude faster sampling rate in comparison with a traditional gas chromatography. The method is presented and dis ...

A systematic approach for thermal stability predictions of chemicals and their risk assessment: Pattern recognition and compounds classification based on thermal decomposition curves

Thierry Meyer, Annik Nanchen, Nadia Baati, Laetitia Mage

In the context of process and product design, predictive models are increasingly employed. Decomposition properties of chemicals may be experimentally determined through calorimetric measurements, and a few molecular structure-based models- which correlate ...

Benzimidazolium salt-based solid-state electrolytes afford efficient quantum-dot sensitized solar cells

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Yefeng Wang

A novel solid-state electrolyte based on 1,3-dihexylbenzimidazolium ([DHexBIm]) cations combined with Br-, BF4- or SCN- anions is used in CdS/CdSe sensitized quantum dot sensitized solar cells (QDSSCs). A power conversion efficiency of 4.26% was achieved w ...

Effects of partial crystallization in Pt-Si-B-based bulk metallic glasses on glass transition and crystallization of the remaining amorphous matrix

Ludger Weber, Hamed Kazemi, Cyrill Werner Cattin, Gilles Hodel

The influence of partial crystallization on the evolution of the characteristic temperatures, i.e. of the glass transition and the onset of crystallization, the density, and the mechanical properties of the bulk metallic glass Pt(49.95)Si(6)AB(24)Ge(3)Cu(1 ...

Reactor Dynamics Investigation Based On Calorimetric Data

Thierry Meyer, Francis Stoessel, Michal Dabros, Charles Ibrahim Guinand

A simple and general procedure has been developed to determine the thermal behaviour of a reactor based on heat balance, PID temperature control, and jacket behaviour. Using only temperature heating/cooling ramps followed by isothermal stages, such a proce ...

A New 1,3,4-Oxadiazole-Based Hole-Transport Material for Efficient CH3NH3PbBr3 Perovskite Solar Cells

Michael Graetzel, Ulf Anders Hagfeldt, Antonio Abate

A new hole-transport material (HTM) based on the 1,3,4-oxadiazole moiety (H1) was prepared through a single-step synthetic pathway starting from commercially available products. Thanks to a deep HOMO level, H1 was used as HTM in CH3NH3PbBr3 perovskite sola ...

Thermal Stability Predictions for Inherently Safe Process Design Using Molecular-Based Modelling Approaches

Thierry Meyer, Annik Nanchen, Francis Stoessel, Nadia Baati

For efficient inherently safe design, awareness of all available options at the appropriate decision-making moment is key. Simulations offer both timely availability and large screening possibilities. Therefore computer-aided product design gained in popul ...
