Conductive textiles of hard matter by electrospinning

Bernd M. Smarsly, Pascal Vöpel & Christoph Seitz
This video should give an insight into the basics of synthesizing nanostructured hybrid materials composed of two different classes of materials, in this case carbon and functional inorganic nanoparticles. These materials are of high interest for current research as they combine the benefits of both material classes. It is usually quite challenging to achieve intimate contact of different materials on the nanometer scale. Non-wovens containing carbon fibers and inorganic nanoparticles can be promising materials for...

Design and synthesis of a molecular photoswitch

Stefan Hecht, Peter H. Seeberger, Alexander G. O’Brian, Farhan R. Bou-Hamdan & François Lévesque
In this video clip, the creative process of developing a chemical concept, translating it into a molecular target structure, and realizing its synthesis is described. Specifically, the implementation of light-control over a thermal chemical equilibrium is explained first on a conceptual level, followed by discussing molecular design considerations and preparation of a desired target structure. Particular emphasis is put on explaining how the molecular target structure is being assembled from small molecular building blocks by...

A Ru-catalysis based rechargeable H2-battery

Bernd Plietker & Shih-Fan Hsu
A Ru-catalyst drives a mobile device for the reversible H2-storage and release. Carbon dioxide and diazabicycloundecene (DBU) are the stoichiometric storage media. The formic acid which is formed within the charging process is a non-toxic and stable liquid that can be stored in bottles or tanks without special precautions.

Chemoenzymatic synthesis of oxygen heterocycles

Frank Hahn, Gesche Berkhan & Franziska Hemmerling
The video shows the setup and analysis of a chemoenzymatic reaction with the AmbDH3 domain on the semipreparative scale. The synthesis of the enzyme precursor as well as a typical procedure for the production of the catalyst are described. The last two decades have seen a tremendous progress in the understanding of secondary metabolite biosynthesis on the genetic, the enzymatic as well as on the structural level. Such biosynthetic pathways contain a plethora of enzymes...

Democratising Knowledge across the Enterprise

Tom Wickham-Jones
Modern businesses and organisations have access to an increasing amount of information. This includes private internal information such as product usage, user profiles, and sales history, as well as public external information such as data on demographics, economic growth, and weather patterns. Despite this opportunity, traditional technologies and approaches often restrict access to only a small number of specialists. To reach out to a broad set of users and democratise this knowledge requires fresh thinking...

What is the color of chocolate? Extracting color values of semantic expressions

Albrecht Lindner, Nicolas Bonnier & Sabine Süsstrunk
We present a statistical framework to automatically determine an associated color for a given arbitrary semantic expression. The expression can not only be a color name but any word or character string. In addition to the color value, we are also able to compute the result’s significance, which determines how meaningful defining the color is for the expression. To demonstrate the framework’s strength we apply it to two well known tasks: assessing memory colors and...

Towards a multivariate probabilistic morphologyfor colour images

Alexandru Caliman, Mihai Ivanovici, Noël Richard & Christine Fernandez-Maloigne
The mathematical morphology for colour images faces the delicate issue of defining a total order in a vectorial space. There are various approaches based on partial or total orders defined for color images. We propose a probabilistic approach, that uses principal component analysis (PCA), for the computation of the convergence colours, i.e. the extrema of a set. Then we define two pseudo-morphological operations, the dilation and the erosion, applying the Chebyshev’s inequality on the first...
