Catalyst deposition on fragile chips

17-Feb-2020

Electrocatalysts can help to obtain chemicals from renewable raw materials or to use alternative energy sources. But testing new catalysts brings challenges. Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst ...

New simulation-experiment combination allows deeper insights into ultrafast light-induced processes

14-Feb-2020

Researchers from Graz University of Technology and the University of Vienna are demonstrating for the first time how the energy flow between strongly interacting molecular states can be better described. Since the 1990s, femtochemistry has been researching ultrafast processes at the molecular ...

Induced flaws in metamaterials can produce useful textures and behavior

Discovery advances the understanding of structural defects and their topological properties

10-Feb-2020

While a piece of paper is usually flat and floppy, the same piece of paper crumpled into a wad is stiff and round. This demonstrates that scrunching changes the texture and behavior of precisely the same material -- paper. A new Tel Aviv University study shows how induced defects in metamaterials ...

Tuneable self-organisation of liquid crystals in nanopores

Innovative path to novel materials with adaptive electrical and optical properties

04-Feb-2020

A team of researchers has used X-rays from DESY's research light source PETRA III to explore the amazingly diverse self-organisation of liquid crystals in nanometre-sized pores. The study, led by Patrick Huber from the Hamburg University of Technology (TUHH), shows how liquid crystals arrange ...

Trends in analysis

03-Feb-2020

From March 31 to April 3, 2020, analytica, the world’s leading trade fair for laboratory technology, analysis and biotechnology, will be held, now for the 27th time, on the exhibition grounds in Munich. From March 31 to April 2, it will be accompanied by the analytica conference, where scientists ...

From 2D crystal to 1D wire

Unexpected behaviour of the material

31-Jan-2020

No volume, not even a surface: a one-dimensional material is like a wire and has properties that are completely different to its 3D counterpart. Physicists at the University of Duisburg-Essen (UDE) have now discovered a system that, at warmer temperatures, forms self-organized wires consisting of ...

Putting a nanomachine to work

30-Jan-2020

A team of chemists at LMU has successfully coupled the directed motion of a light-activated molecular motor to a different chemical unit – thus taking an important step toward the realization of synthetic nanomachines. Molecular motors are chemical compounds that convert energy into directed ...

Determining the atomic structure of natural products more rapidly and accurately

23-Jan-2020

Many drugs are derived from natural products. But before natural products can be exploited, chemists must first determine their structure and stereochemistry. This can be a major challenge, particularly when the molecules cannot be crystallized and contain only few hydrogen atoms. A new NMR-based ...

Chemists allow boron atoms to migrate

Researchers present carbon-carbon couplings in which the semi-metal boron is retained

21-Jan-2020

Organic molecules with atoms of the semi-metal boron are among the most important building blocks for synthesis products that are needed to produce drugs and agricultural chemicals. However, during the usual chemical reactions used in industry, the valuable boron unit, which can replace another ...

Miniature double glazing

Material developed which is heat-insulating and heat-conducting at the same time

21-Jan-2020

Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and ...
