Metal Ion Implantation for the Fabrication of Stretchable Electrodes on Elastomers

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on low-energy metal ion implantation by filtered cathodic vacuum arc to create highly deformable electrodes on polydimethylsiloxane (PDMS) membranes. Implantation leads to the creation of nanometer-size clusters in the first 50 nm below the surfa ...

Electrophoretic deposition of multi-scale structured TiO2 surfaces

The long term fixation of biomedical implants constitutes an issue in the clinical praxis. Implant fixation can be improved by functionalizing its surface. In fact, the tissue response around an implant is conditioned by its surface morphological and chemi ...

Barium titanate nanoparticles used as second harmonic radiation imaging probes for cell imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

Luminescent markers play a key role in imaging techniques for life science since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocry ...

Magnetoresistive junctions based on epitaxial graphene and hexagonal boron nitride

Alfredo Pasquarello, Oleg Yazyev

We propose monolayer epitaxial graphene and hexagonal boron nitride (h-BN) as ultimate thickness covalent spacers for magnetoresistive junctions. Using a first-principles approach, we investigate the structural, magnetic, and spin transport properties of s ...

Nanostructured Ceramic Coatings for Drug Delivery

Heinrich Hofmann, Laurent-Dominique Piveteau, Arnaud Tourvieille de Labrouhe, Karin Dittmar

Drug eluting stents (DES) have been successfully implemented in clinical practice in the treatment against coronary artery disease. Compared to the implantation of bare metal stents, restenosis rates decreased significantly after stenting of DES into coron ...

Harmonic Holographic Microscopy Using Nanoparticles as Probes for Three-Dimensional Cell Imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We demonstrate the three-dimensional imaging capability of harmonic holographic microscopy by using the second harmonic generation from BaTiO3 nanoparticles as the signal. Three-dimensional distributions of the BaTiO3 nanoparticles in biological cells are ...

Effect of Mixing and Other Operating Parameters in Sol-Gel Processes

Paul Bowen

In this work the effect of mixing on a sol-gel process is quantitatively investigated. Titanium dioxide synthesis from titanium tetra-isopropoxide is used as a test reaction. Solutions of titanium alkoxide in isopropyl alcohol and water in isopropyl alcoho ...

Protoporphyrin IX sensitized titanium oxide gel electrode

Hubert Girault, Christophe Roussel, Bin Su

Titanium oxide (Ti(O)) xerogel films functionalized by protoporphyrin IX (PPIX) and ferrocene carboxylic acid (FCA) were deposited on indium tin oxide (ITO) electrodes following a sol–gel synthesis. PPIX and FCA were first complexed to titanium oxide precu ...

Nd:YAG laser joining between stainless steel and nickel-titanium shape memory alloys

Michel Rappaz, Aïcha Hessler-Wyser, Jonas Vannod

Nickel-Titanium (NiTi) shape memory alloys are often used in medical component devices, for instance as guide wires for neurological surgery applications. The manufacture of such devices becomes more and more challenging, especially considering the need to ...

Cohesion and adhesion of nanoporous TiO2 coatings on titanium wires for photovoltaic applications

Yves Leterrier, John Christopher Plummer, Nelson Da Costa

The working electrode of a dye-sensitized photovoltaic fiber is constituted of a porous TiO2 coated titanium wire. The cohesion and adhesion of such a brittle oxide coating on the ductile metal substrate are identified as crucial factors in maintaining pho ...
