Experimental characterization and stochastic models for time-dependent rupture of thin-ply composite laminates

Thin-laminate composites with thicknesses below 200 mu m hold significant promise for future, larger, and lighter deployable structures. This paper presents a study of the time-dependent failure behavior of thin carbon-fiber laminates under bending, focusi ...

Pd(II)-Catalyzed Aminoacetoxylation of Alkenes Via Tether Formation

Jérôme Waser, Stefano Nicolai, Ashis Kumar Das, Thomas Rossolini

A Pd-catalyzed method based on the use of a molecular tether is described for olefin difunctionalization. Enabled by an easily introduced trifluoroacetaldehyde-derived tether, a simultaneous introduction of oxygen and nitrogen heteroatoms across unsaturate ...

Tether Climbing Robot for Environmental Sampling and Data Collection

Josephine Anna Eleanor Hughes, Kai Christian Junge, Max Mirko Polzin, Qinghua Guan, Nicolas Mathis Minder

Developing robots that can explore environments without disturbing the natural flora and fauna could allow a safe exploration for both the robot and its surroundings. However, this can involve exploring complex or challenging environments, for example extr ...

Mechanical Activation of Chemical Bonds at Polymer Interfaces

Julian Nicolas Bleich

Polymer brushes are a specific class of polymer thin films in which each chain is tethered to the underlying substrate via one chain end. In sufficiently densely grafted assemblies, the individual polymer chains are forced into an extended chain conformati ...

Palladium Catalysed Intramolecular Carbo-oxygenation of Propargylic Amines to Access 1,2-Amino Alcohols and alpha-Amino Ketones via in situ Tether Formation

Phillip Gulliver Dominic Greenwood

a-Amino ketones and 1,2-amino alcohols are important structural motifs in organic chemistry, that can be observed in natural products, pharmaceutically and bioactive compounds. For these reasons, they constitute privileged targets for the development of ne ...

Palladium-Catalyzed Carboamination of Allylic Alcohols Using a Trifluoroacetaldehyde-Derived Tether

Jérôme Waser, Bastian Antoine Rodolphe Claude Muriel, Ugo Jonathan Orcel

The selective palladium-catalyzed carboamination of allylic alcohols is reported on the basis of the use of an easily introduced trifluoroacetaldehyde-derived tether. Aminoalkynylation reactions were realized using alkynyl bromides and commercially availab ...

Analysis of the Maximum Efficiency of Kite-Power Systems

Dominique Bonvin, Grégory François, Sean Costello

This paper analyzes the maximum power that a kite, or system of kites, can extract from the wind. Firstly, a number of existing results on kite system efficiency are reviewed. The results that are generally applicable require significant simplifying assump ...

Delay times in a cellular traffic flow model for road sections with periodic outflow

A simple cellular automaton to model traffic flow is used to analyze the impact of traffic lights on travel times. The model is investigated on a stretch of road with open boundaries, where the inflow is driven stochastically, but the outflow is controlled ...
