The invention describes a novel heating boiler for wooden pellets for the implementation in CHP plants. Through the use of a counter-flow the air gets cleaned effectively and automatically from ash that is produced while the gasification of the wooden pellets. High temperature corrosion and fouling of the heat exchanger of a stirling engine can be reduced drastically. Up-to-date emission instructions can be reached at high effiency.

Using a single molecule as a sensor, scientists in Jülich have successfully imaged electric potential fields with unrivalled precision. The…

The invention describes a method to use of operating vibrations to determine the static stiffness of e.g. car bodies.

Raman imaging is emerging and will have some obvious advantages over fluorescence microscopy. Based on a sweeping source TICO-Raman provides a fully fiber laser based rapid nanosecond hyperspectral stimulated Raman microscopy, spectroscopy and endoscopy. It’s a unique combination of high speed, broad spectral coverage, high spectral resolution and high spatial resolution.

Quantum computing — which aims to use particles on the atomic scale to make calculations and store the results — has the potential to solve some key problems…

ETH-professor Huber is a theoretical physicist who, for several years now, has focused his attention on so-called topological insulators, i.e., materials whose…

Porous carbon or activated carbons are important materials for the purification of gases and liquids. They are used as adsorbents in medical applications as well as electrode materials in batteries. The presented invention provides a process for the production of porous carbon by embedding inorganic nanoparticles into a carbonaceous matrix followed by a reaction with a halogen gas. The resulting material is Kroll-Carbon, a highly porous carbon material with a hierarchical pore architecture, containing well-defined micropores and adjustable mesopores.
It is suitable for applications in separation and purification, like the removal of VOCs (volatile organic compounds), and biomolecules, but also for the encapsulation of enzymes, or as a electrode material for supercapacitors and batteries.

The innovative technology provides binary precursors, which keep all advantages of the known precursors TBAs and TBP, but deliver two group-15 el-ements in a defined molar ratio in one chemical component (one-component precursors). Any pairs of group-15 elements (N, P, As, Sb and Bi) may be combined in these components.

The new technology provides a simple and inexpensive process for the synthesis of proteins that exhibit reliable functionality by posttranslational modifications, like e.g. glycosylation. Furthermore, the assembly of protein complexes is enabled. These are secreted from the cells into the medium and can be therefore easily obtained.

Cavities measuring up to a few hundred meters in diameter can be found under the surface of Rosetta’s comet 67P/Churyumov-Gerasimenko. They can be instable and…
