A crystal wedding in the nanocosmos
25-Jul-2014
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Vienna University of Technology and the Maria Curie-Skłodowska University Lublin have succeeded in embedding nearly perfect semiconductor crystals into a silicon nanowire. With this new method of producing hybrid nanowires, very ...
Nanoscale ruler reveals organization of the cell membrane
Freiburg biologists measure distances and the arrangement of membrane molecules in nanometer range
27-Jun-2014
After a ten-year effort, Prof. Dr. Michael Reth from the Institute of Biology III of the University of Freiburg and the Max Planck Institute of Immunobiology and Epigenetics has developed a method to investigate the cell surface's organization on a nanometer scale. This allows him to monitor how ...
The Sweetest Calculator in the World
Chemists let fluorescent sugar sensors ‘calculate’
23-Jun-2014
In a chemistry lab at the Friedrich Schiller University Jena (Germany): Prof. Dr. Alexander Schiller works at a rectangular plastic board with 384 small wells. The chemist carefully pipets some drops of sugar solution into a row of the tiny reaction vessels. As soon as the fluid has mixed with ...
High-speed snapshots of biomolecules
PETRA III pioneers protein serial crystallography at synchrotrons
05-Jun-2014
Using DESY's synchrotron light source PETRA III, scientists have pioneered a new way to analyse delicate biomolecules. The novel approach, borrowed from a new class of high-intensity X-ray sources called free-electron lasers (FELs), could reveal the atomic structure of proteins that were ...
Learning from sharks
19-May-2014
Custom-tailored antibodies are regarded as promising weapons against a multitude of serious illnesses. Since they can accurately recognize specific structures on the surface of viruses, bacteria or cancer cells, they are already being deployed successfully in cancer diagnostics and therapy, as ...
Thinnest feasible membrane produced
29-Apr-2014
A new nano-membrane made out of the “super material” graphene is extremely light and breathable. Not only can this open the door to a new generation of functional waterproof clothing, but also to ultra-rapid filtration. The membrane produced by the researchers at ETH Zurich is as thin as is ...
Using antineutrinos to monitor nuclear reactors
Astroparticle physics methodology applied to nuclear facility monitoring
29-Apr-2014
When monitoring nuclear reactors, the International Atomic Energy Agency (IAEA) has to rely on input given by the operators. In the future, antineutrino detectors may provide an additional option for monitoring. However, heretofore the cumulative antineutrino spectrum of uranium 238 fission ...
Protecting olive oil from counterfeiters
28-Apr-2014
Who guarantees that expensive olive oil isn't counterfeit or adulterated? An invisible label, developed by ETH researchers, could perform this task. The tag consists of tiny magnetic DNA particles encapsulated in a silica casing and mixed with the oil. Just a few grams of the new substance are ...
Steering chemical reactions with laser pulses
24-Apr-2014
Usually, chemical reactions just take their course, much like a ball rolling downhill. However, it is also possible to deliberately control chemical reactions: at the Vienna University of Technology, molecules are hit with femtosecond laser pulses, changing the distribution of electrons in the ...
Convincing performance by CHEMIE.DE at analytica 2014
An over 22 percent increase in industry contacts at the booth
16-Apr-2014
A complete success - this sums up CHEMIE.DE Information Service's appearance at analytica 2014 in Munich. Europe's largest online information platform for the chemical, life science and analytics industries caught the attention of the visitors with an eye-catching, ideally placed booth and an ...
