Amorphous silicon-based microchannel plates

Christophe Ballif, Sylvain Dunand, Yannick Samuel Riesen, François Eric Powolny, Andrea Franco

Microchannel plates (MCP) based on hydrogenated amorphous silicon (a-Si:H) were recently introduced to overcome some of the limitations of crystalline silicon and glass MCP. The typical thickness of a-Si:H based MCPs (AMCP) ranges between 80 and 100 μm and ...

Role of elastin anisotropy in structural strain energy functions of arterial tissue

Nikolaos Stergiopoulos, Edouard Fonck

The vascular wall exhibits nonlinear anisotropic mechanical properties. The identification of a strain energy function (SEF) is the preferred method to describe its complex nonlinear elastic properties. Earlier constituent-based SEF models, where elastin i ...

Automated Detection and Segmentation of Synaptic Contacts in Nearly Isotropic Serial Electron Microscopy Images

Marco Cantoni, Graham Knott

We describe a protocol for fully automated detection and segmentation of asymmetric, presumed excitatory, synapses in serial electron microscopy images of the adult mammalian cerebral cortex, taken with the focused ion beam, scanning electron microscope (F ...

Quantification of platinum deposition in polymer electrolyte fuel cell membranes

Platinum catalyst dissolution with subsequent reduction and deposition of Pt particles in the membrane can lead to a significant loss of polymer electrolyte fuel cell (PEFC) performance. To quantify the amount of deposited platinum, a novel transmission el ...

Exploring red blood cell membrane dynamics with digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Jonas Kühn, Daniel Boss

Digital Holographic Microscopy (DHM) has been used to investigate the spontaneous cell membrane fluctuations (CMF) of the Red Blood Cell. DHM as an interferometric technique is able to accurately provide the wavefront deformation induced by a transparent s ...

Distributed strain measurements using fiber Bragg gratings in small-diameter optical fiber and low-coherence reflectometry

Marco Lai, Hans Georg Limberger, Dragan Coric, Aiping Luo

Optical low coherence reflectometry and fiber Bragg gratings written in small diameter (50 micrometer) optical fibers were used for measurements of non-homogenous internal strain fields inside an epoxy specimen with sub-grating length resolution. The resul ...

A protocol for preparing GFP-labeled neurons previously imaged in vivo and in slice preparations for light and electron microscopic analysis

Graham Knott, Egbert Welker

In vivo imaging of green fluorescent protein (GFP)-labeled neurons in the intact brain is being used increasingly to study neuronal plasticity. However, interpreting the observed changes as modifications in neuronal connectivity needs information about syn ...

Monitoring of hygrothermal ageing effects in an epoxy resin using FBG sensor: A methodological study

John Botsis, Joël Cugnoni, Dimitrios Karalekas

This study demonstrates the feasibility of using fibre Bragg grating (FBG) sensors to monitor the effects of hygrothermal ageing on the axial strains in a cylindrical epoxy specimen with a centrally located optical glass fibre. A 24 mm long FBG, inscribed ...

Model-Based 2.5-D Deconvolution for Extended Depth of Field in Brightfield Microscopy

Michaël Unser, Dimitri Nestor Alice Van De Ville, François Aguet

Due to the limited depth of field of brightfield microscopes, it is usually impossible to image thick specimens entirely in focus. By optically sectioning the specimen, the in-focus information at the specimen's surface can be acquired over a range of imag ...
