Reversible self-organization of poly(ethylene glycol)-based hybrid block copolymers mediated by a de novo four-stranded α-helical coiled coil motif

This paper describes the synthesis and supramolecular organization of two novel hybrid diblock copolymers based on poly(ethylene glycol) (PEG) and peptide sequences inspired by the coiled coil protein folding motif. The self-organization of the diblock cop ...

From supramolecular polymersomes to stimuli-responsive nano-capsules based on poly(diene-b-peptide) diblock copolymers

Harm-Anton Klok

This paper discusses the self-assembly of block copolymers into vesicular morphology. After a brief state of art of the field, a system based on an amphiphilic poly(butadiene)- b-poly(-L-glutamic acid) (PB- b-PGA) diblock copolymer in aqueous solution is d ...

Optically sectioned image generating method for microscopy imaging apparatus involves combining measured characteristics of signals from respective positions of conjugate image plane to generate optically sectioned image of specimen

Theo Lasser, François Richard Vuille, Stéphane Bourquin, Jelena Mitic, Karsten Plamann

A method and a microscopy imaging apparatus for generating an optically sectioned image of a specimen are provided. The method comprises the steps of:illuminating the specimen with a modulating, spatially periodic illumination pattern; imaging said specime ...

Parallel optical coherence tomography in scattering samples using a two-dimensional smart-pixel detector array

René Salathé, Theo Lasser, Boris Clément Karamata, Stéphane Bourquin, Markus Laubscher

Parallel optical coherence tomography in scattering samples is demonstrated using a 58 x 58 smart-pixel detector array. A femtosecond mode-locked Ti:Sapphire laser in combination with a free space Michelson interferometer was employed to achieve 4 mum long ...

Self-assembling biomaterials: L-lysine-dendron-substituted cholesteryl-(L-lactic acid)n

Harm-Anton Klok

This report describes the synthesis and supramolecular organization of a novel class of linear-dendritic block copolymers. The molecules, which are termed rodcoil dendrons, consist of a cholesterol moiety that is attached to L-lysine dendrons of three diff ...

Gold nanoantennas as probes for near-field optical microscopy

The main purpose of this thesis is to explore a new concept of SNOM probes. In order to produce more reliable and reproducible tips, we propose to graft a single gold particle of 60 nm diameter onto the aperture of a SNOM probe. The expected advantage of s ...

Extending Kubelka-Munk's Theory with Lateral Light Scattering

Roger Hersch, Patrick Emmel, Safer Mourad

Due to its simplicity, the theory of KUBELKA-MUNK [1] has found a wide acceptance for modeling the optical properties of light scattering materials. However, the concept is not explicitly adapted to predict halftone prints on paper. In this respect, a rece ...

Scattering experiments with a diving cylinder

Olivier Martin

We present numerical experiments of light scattering by a circular dielectric cylinder embedded in a stratified background, using the Greens tensor technique. The stratified background consists of two or three dielectric layers, the latter forming an anti- ...

Measuring and modeling optical diffraction from subwavelength features

Demetri Psaltis, Xiao Wang

We describe a technique for studying scattering from subwavelength features. A simple scatterometer was developed to measure the scattering from the single-submicrometer, subwavelength features generated with a focused ion beam system. A model that can des ...

A Unified model for color prediction of halftoned prints

Roger Hersch, Patrick Emmel

This study introduces a new model and a new mathematical formulation describing the light scattering and ink spreading phenomena in printing. The new model generalizes the classical Kubelka-Munk theory, and unifies it with the Neugebauer model within a sin ...
