A Caveat on SCC-DFTB and Non-covalent Interactions Involving Sulfur Atoms

Riccardo Petraglia

Accurate modeling of non-covalent interactions involving sulfur today is ubiquitous, particularly with regards to the role played by sulfur-containing heterocycles in the field of organic electronics. The density functional tight binding (DFTB) method offe ...

Catalysts for High Temperature Gas Cleaning in the Production of Synthetic Natural Gas from Biomass

Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...

Mechanical properties of SiOx gas barrier coatings on polyester films

Yves Leterrier

This paper reports the impressive mechanical properties of 1 μm thick carbon-containing SiOx gas barrier coatings, characterised using the uniaxial fragmentation test. Such coatings have been found to act as excellent barriers to water vapour permeation pa ...

Chemistry and climate interactions

Luca Pozzoli

Atmospheric trace gases and aerosols and climate interact in many ways. A quantitative assessment of the influence of trace gases and aerosols on climate can only be achieved if the interactions and feedbacks among these three major components are accounte ...

Formation of Microcapsules from Polyelectrolyte and Covalent Interactions

Urs von Stockar, Ian William Marison, Véronique Breguet, Raphaël Gugerli, Mimma Pernetti

A new approach combining electrostatic and covalent bonds was established for the formation of resistant capsules with long-term stability under physiol. conditions. Three kinds of interactions were generated in the same membrane: (1) electrostatic bonds b ...

Liquid-core capsules as a tool in biotransformations

The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...

First-Principles Simulations of C-S Bond Cleavage in Rhenium Thioether Complexes

Ursula Röthlisberger

We present first-principles mol. dynamics studies of the reductive C-S bond cleavage reaction in hexathioether complexes of the form [Re(9S3)2]m+ (with 9S3 = 1,4,7 trithiacyclononane and m = 1,2). Our calcns. show that electron transfer and bond dissocn. t ...

Water Adducts of BX3 and CX3+: Implications for Structure, Bonding, and Reactivity

Ines Raabe

Good quality ab initio calcns. (MP2) show that the water adducts of BX3 and CX3+ have totally different structures (X = F-I). While all H2O-BX3 complexes have classical Cs sym. structures with strong B-O bonds and addnl. H-bonding, the heavier CX3+ cations ...

Towards magnetic engineering at metal surfaces

The aim of this thesis is twofold: on the one hand to demonstrate a new method of building magnetic nanostructures at surfaces and on the other hand to present the construction of a new 1K UHV Low Temperature STM aimed at coupling the spatial resolution of ...
