Metal oxide layers for semiconductor sensors or solar cells (e.g. tandem solar cells based on Cu2O) are usually produced by sputtering (HF or RF sputtering).
The novel method basically involves the controlled addition of hydrogen gas during the proper sputtering process. Thus, signif-icant improvements concerning the electrical properties of for example charge carrier concentration, charge carrier mobility and sheet resistance are achieved
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.
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.
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.
