Method for preparing an at least partially acetal-protected sugar

Jeremy Luterbacher, Songlan Sun, Lorenz Perry Manker, Anastasiia Komarova

The present invention relates to a method for preparing an at least partially acetal-protected sugar involving the step of reacting a sugar or a sugar derivative selected from the group consisting of an aldopentose, an aldohexose, an aldopentoside and an a ...

Extraction and controlled functionalization of lignin for materials applications

Stefania Bertella

Lignin is a renewable aromatic polymer that due to its abundance and unique chemical structure is a promising candidate to replace aromatic materials that are currently sourced from fossil oil. The same structure of lignin poses however drawbacks for its v ...

Drone-ready robotic gripper powered by shape memory alloys

Gabriel Maquignaz

For this project, the goal is to design a flexure-based gripper mechanism actuated by a Shape-Memory Alloy spring (SMA) and to be mounted on a drone. While being complex to control precisely and having a very small bandwith, SMA actuators show a formidable ...

Enhancing Hydrogen Evolution Activity of Au(111) in Alkaline Media through Molecular Engineering of a 2D Polymer

Klaus Kern, Patrick Eduard Alexa

The electrochemical splitting of water holds promise for the storage of energy produced intermittently by renewable energy sources. The evolution of hydrogen currently relies on the use of platinum as a catalyst-which is scarce and expensive-and ongoing re ...

WILEY-V C H VERLAG GMBH2020

Phase separation of immiscible fluids is a common phenomenon in polymer chemistry, and is recognized as an important mechanism by which cells compartmentalize their biochemical reactions. Biomolecular condensates are condensed fluid droplets in cells that ...

2020

Adhesion towards glass and interfacial healing of partially supramolecular hybrid polymer networks featuring a range of H-bdnds content were investigated through two dedicated adhesion test methods. In a first series of tests, adhesion strength was measure ...

On-Surface Assembly and Reactions of Organic Molecules in Ultra-High Vacuum

Claudius Morchutt

This thesis comprises the study of two types of 2D materials, those stabilized by non-covalent and those by covalent interactions. They are synthesized and studied on well-defined metallic surfaces in ultra-high vacuum (UHV). The self-assembly of terephtha ...

EPFL2016

Synthesis and characterization of polymer-based composites containing carbon nanostructures is the focus of this dissertation. The main polymer which has been used for this research is SU8. The motivation of the work is to overcome the drawbacks of SU8 e.g ...

The persistence length of adsorbed dendronized polymers

Giovanni Dietler, Michal Borkovec, Plinio Maroni, Andrey Mikhaylov

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the ...
