Oscillatory fracture paths in thin elastic sheets

Pedro Miguel Nunes Pereira de Almeida Reis

We report a novel mode of quasi-static oscillatory crack propagation when a cutting tip of moderately large width is driven through a thin brittle polymer film. Experiments show that the amplitude and wavelength of the oscillatory crack paths scale linearl ...

Electrochemical Micromachining of Titanium through a Laser Patterned Oxide Film

Patrik Willi Hoffmann, Dieter Landolt

Selective dissolution of titanium through a laser patterned oxide film has been achieved in a 3M sulfuric acid-methanol electrolyte. The 250 nm thick oxide film was formed anodically on a flat titanium surface in 0.5 M sulfuric acid. The patterning of the ...

Process for producing nanostructured metal oxide thin films on substrates

Ulf Anders Hagfeldt

A process for producing at least one epitaxial, nanostructured thin film of metal oxide and/or a hydrated metal oxide on at least one substrate placed in a container and a substrate/thin film thereof, comprises placing the substrate at any location in the ...

La1-xSrxCoO3 as electrode materials for ferroelectric thin film applications

Paul Muralt, Nicolas Ledermann

PZT thin films for memory applications are known to lack sufficient resistance versus polarization fatigue when used together with platinum. One possible solution for this problem is to use conductive oxides like La1-xSrxCoO3 (LSCO) as an electrode. In thi ...

Properties of thin anti-adhesive films used for the replication of microstructures in polymers

Giorgio Margaritondo

The aim of this work was to investigate the degradation of the anti-adhesive properties of protective PTFE films during the hot embossing of thermoplasts, and to identify possible failure causes which reduce the lifetime of these films. A comparative XPS s ...

Photoinduced poling of lead titanate zirconate thin films

Nava Setter

The influence of ultraviolet (UV) illumination on piezoelectric properties is investigated in lead zirconate titanate (PZT) thin films. It is found that the poling procedure is more effective when the film is exposed to a broadband UV light in the presence ...
