Automatic Detection of Dust and Scratches in Silver Halide Film using Polarized Dark-Field Illumination

Sabine Süsstrunk, Dominic Rüfenacht

We present a method to automatically detect dust and scratches on photographic material, in particular silver halide film, where traditional methods for detecting and removing defects fail. The film is digitized using a novel setup involving crosspolarizat ...

Formation of (113) texture in fcc nitride thin films and its influence on the film properties

Ayat Karimi, Alireza Karimi, Akshath Raghu Shetty

This work presents a study of XRD measurements on the development of the (113) preferential orientation with film thickness for Ti0.67Al0.33N films grown on Si(100) substrates by pulsed DC magnetron sputtering. The buildup of (113) texture was observed usi ...

Light trapping in solar cells at the extreme coupling limit

Christophe Ballif, Hans Peter Herzig, Franz-Josef Haug, Corsin Battaglia, Ali Naqavi

We calculate the maximal absorption enhancement obtainable by guided mode excitation in a weakly absorbing dielectric slab over wide wavelength ranges. The slab mimics thin film silicon solar cells in the low absorption regime. We consider simultaneously w ...

Reactive Sputtering of Bismuth Vanadate Photoanodes for Solar Water Splitting

Le Chen

Bismuth vanadate (BiVO4) has attracted increasing attention as a photoanode for photoelectrochemical (PEC) water splitting. It has a band gap in the visible light range (2.4-2.5 eV) and a valence band position suitable for driving water oxidation under ill ...

Study of Amyloid beta-Peptide (A beta 12-28-Cys) Interactions with Congo Red and beta-Sheet Breaker Peptides Using Electrochemical Impedance Spectroscopy

Hubert Girault, Raheleh Partovi Nia

A surface-based approach is presented to study the interactions of A beta 12-28-Cys assembled on gold surfaces with Congo red (CR) and a beta-sheet breaker (BSB) peptide. The various aspects of the peptide film have been examined using different electroche ...
