Nanoscale Lithography and Thermometry with Thermal Scanning Probes

Samuel Zimmermann

Thermal scanning probe lithography (t-SPL) is an advanced lithography technique in which a heated atomic force microscope tip locally modifies a sample material. Due to the nanometer-sized tip apex diameter, t-SPL enables patterning of sub-10 nm structures ...

Towards aerospace grade thin-ply composites: Effect of ply thickness, fibre, matrix and interlayer toughening on strength and damage tolerance

John Botsis, Robin Amacher, Joël Cugnoni, Larissa Sorensen, Sébastien Kohler

Thin-ply composites represent a promising approach to further improve the performance of carbon fibre composite structures thanks to their ability to delay the onset of matrix cracking and delamination up to the point of fibre dominated failure. However, t ...

Silk Fibroin as a Resist for Thermal Scanning Probe Lithography

Jürgen Brugger, Xiao Sheng Zhang, Ya Wang, Samuel Zimmermann

We present for the first time nano-scale patterning of silk fibroin with a thermal scanning probe to locally convert water-insoluble crystalline silk into the water-soluble phase. Our first experiments demonstrate silk as a fully water-based resist for the ...

A transparent silk-fibroin-based triboelectric microgenerator for airflow energy harvesting

Jürgen Brugger, Xiao Sheng Zhang, Ya Wang, Yinben Guo

We present a new transparent high-performance triboelectric microgenerator (TEMG) based on an emerging material, silk fibroin. Silk fibroin has a strong ability to lose electrons and occupies a top-level positive position in the triboelectric series. It th ...

From spider webs to a fibre-optic chemical sensor

Luc Thévenaz, Isabelle Dicaire, Kenny Hey Tow, Desmond Chow Ming Chia

From the spider’s perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of prey on its web. For scientists, dragline silk - directly extracted from spiders - is a tough, biodegradable a ...
