Influence of Si3N4 fillers and pyrolysis profile on the microstructure of additively manufactured silicon carbonitride ceramics derived from polyvinylsilazane

In this work, various methods were used to improve the printability of a photocurable polyvinylsilazane resin filled with silicon nitride particles for digital light processing. The developed resin was used as a preceramic polymer for polymer-to-ceramic co ...

Processing factors affecting roughness, optical and mechanical properties of nanocellulose films for optoelectronics

Tiffany Abitbol

This work aims to understand how nanocellulose (NC) processing can modify the key characteristics of NC films to align with the main requirements for high-performance optoelectronics. The performance of these devices relies heavily on the light transmittan ...

Nanophotonic biosensors harnessing van der Waals materials

Hatice Altug

Low-dimensional van der Waals (vdW) materials can harness tightly confined polaritonic waves to deliver unique advantages for nanophotonic biosensing. The reduced dimensionality of vdW materials, as in the case of two-dimensional graphene, can greatly enha ...

On Advanced Large-Field Photolithography

Raoul Kirner

The information age we live in today relies on highly integrated devices. They are fabricated with the help of photolithography, the patterning technique at the heart of their production. With the continuous demand for higher integration density to achieve ...

Unveiling the Concentration-Dependent Grain Growth of Perovskite Films from One- and Two-Step Deposition Methods: Implications for Photovoltaic Application

Mohammad Khaja Nazeeruddin, Yi Zhang, Peng Gao

In order to achieve high-efficiency perovskite solar cells, understanding both the crystal structure and the optoelectronic properties of perovskite layers is of importance. This paper uses crystallization analysis and the modeling study of two different p ...

Color changing effects with anisotropic halftone prints on metal

Roger Hersch, Petar Pjanic

We propose a color reproduction framework for creating specularly reflecting color images printed on a metallic substrate that change hue or chroma upon in-plane rotation by 90°. This framework is based on the anisotropic dot gain of line halftones when vi ...

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 ...

Resonant absorption of a chemically sensitive layer based on waveguide gratings

Hans Peter Herzig, Vincent Paeder, Marc Schnieper, Guillaume Basset, Laurent Davoine

A colorimetric sensor providing a direct visual indication of chemical contamination was developed. The sensor is a combination of a chemically sensitive dye layer and a resonant waveguide grating. Enhancement of the light absorption by the photonic struct ...
