Cyanine platelet single crystals: growth, crystal structure and optical spectra
Frank Nüesch, Jakob Heier, Antonia Neels
Crystalline organic semiconducting materials are much in demand for multiple electronic and optoelectronic device applications. Here, solution grown ultrathin rhombic crystals of a trimethine carbocyanine anionic dye are used to establish relationships bet ...
Royal Society of Chemistry2018High diffusion barrier and piezoelectric nanocomposites based on polyvinylidene fluoride-trifluoroethylene copolymer and hydrophobized clay
Yves Leterrier, Dragan Damjanovic, Antonia Neels, Sara Dalle Vacche, Olha Sereda, Alex Dommann
Nanocomposites based on polyvinylidene fluoride– trifluoroethylene copolymer and up to 4 vol % of hydrophobized clay nanoparticles are investigated. The structure, piezoelectric properties, and oxygen permeability of solvent cast films are analyzed before ...
Wiley-Blackwell2017Where is the limit? Yield strength improvement in silicon micro-structures by surface treatments
Antonia Neels, Alex Dommann, Tobias Bandi
Imperfections, like surface roughness and defects, introduced by common manufacturing processes are recognized to favor failure of microfabricated components and systems. Up to now only a reduced part of the ideal strength prediction by zero Kelvin quantum ...
Wiley-V C H Verlag Gmbh2016Mild synthesis of mercaptonitriles from vinyl nitriles and their cyclization reactions
Thiol-ene addition of thioacetic acid A is widely used in the synthesis of thiols from vinyl precursors, but so far has not been conducted on non-conjugated vinyl nitriles. The challenge when vinyl nitriles are used is to selectively conduct the thiol-ene ...
Royal Soc Chemistry2016High Piezoelectric Longitudinal Coefficients in Sol-gel PZT Thin Film Multilayers
Paul Muralt, Antonia Neels, Silviu Cosmin Sandu, Alex Dommann, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma
A five-layer stack of lead zirconate titanate (PZT) thin films with Pt electrodes was fabricated for potential applications in nanoactuator systems. The 1 mu m thick PZT films were deposited by a sol-gel technique, the platinum electrodes by sputtering. Th ...
Wiley-Blackwell2014Process influences on the structure, piezoelectric, and gas-barrier properties of PVDF-TrFE copolymer
Yves Leterrier, Dragan Damjanovic, Antonia Neels, Olha Sereda, Alex Dommann
The influence of annealing between the Curie transition and the melting point of solvent cast polyvinylidene fluoride trifluoroethylene copolymer films on the crystalline structure, mechanical and electrical properties, and oxygen permeability is investiga ...
2014Making MEMS more suited for Space: Assessing the proton-radiation tolerance of structural materials for microsystems in orbit
Herbert Shea, Antonia Neels, Alex Dommann, Tobias Bandi
We report on the susceptibility of structural MEMS materials to proton radiation damage. Radiation tests at spacerelevant doses were conducted on MEMS resonators. The two materials examined were single crystal silicon and SU-8, which are both in widespread ...
2013Proton-Radiation Tolerance of Silicon and SU-8 as Structural Materials for High-Reliability MEMS
Herbert Shea, Antonia Neels, Alex Dommann, Tobias Bandi
The susceptibility of single-crystal silicon and SU-8 resonators to proton-radiation induced degradation was investigated. Both materials are in widespread use for microsystems structures, thus the stability of the mechanical properties must be ensured ove ...
Institute of Electrical and Electronics Engineers2013Molecular Networks Based on Dative Boron-Nitrogen Bonds
Rosario Scopelliti, Kay Severin, Antonia Neels, Olha Sereda, Erin Sheepwash, Vincent Krampl
The BN connection: Crystalline and soft molecular networks can be constructed using dative BN bonds (see picture). The networks are obtained in a one-step, three-component reaction involving a triboronic acid, a catechol, and a bipyridyl linker. ...
2011Chelating NHC Ruthenium(II) Complexes as Robust Homogeneous Hydrogenation Catalysts
Gabor Laurenczy, Antonia Neels
A series of ruthenium(II) N-heterocyclic carbene chelate complexes were prepd. by using bidentate chelating alkene-carbene, thioether-carbene, carboxylate-carbene and bis-carbene ligands. Metalation of 1-R-3-X-imidazolium salts (1-3, R = Me, X = allyl, MeS ...
