Intelligent Method and System for the Analysis of Optical Retardation

The new method enables the determination of birefringence from unknown samples in absolute values without a calibration of the apparatus. Furthermore it allows a quantitative analysis of the materials with regard to robustness, elongation at rupture and colour uniformity. The method can easily be integrated in normal polarisation microscopes and provides the possibility of analysing optical retardation with spatial resolution. 21.07.2015 | nachricht Read more

Vibration tests for objects

In order to conduct vibration analyses to determine eigenfrequencies, modal damping, and eigenforms, a test specimen must be set into position and subjected to vibrations. The invention is an arrangement and process that simultaneously enables the free-free positioning of test specimens and the excitation of vibrations. 21.07.2015 | nachricht Read more

Adhesin with high chitin-binding specificity

The new recombinant protein is based on the recently identified Cea1 adhesin from the yeast Pichia pastoris. It provides a high specificity for non-reducing N-acetylglucosamine (GlcNAc) ends of non-crystalline chitin, chitin-like polymers, or N-linked glycans, while recognition of glucose, glucosamine, or N-acetylneuraminic acid (Neu5Ac) is subordinate. The technology therefore enables highly specific binding of chitin or chitin-like polymers in the context of biomedical or biotechnological applications. 21.07.2015 | nachricht Read more

MicroDetec - Non-invasive Multiparameter Detection in Microfluidic Devices

While conventional sensor concepts are often not suitable for micro dimensions and too expensive, the new sensor system MicroDetec is ideal for continuous operating mode and sensitive flow conditions in microreactors. The measurement method exploits the phenomenon, that the fluids in biphasic flow in non-conductive micro channels undergo a polarization. This polarization is monitored by an electrode, which is flush fitted on a non-conductive channel (e.g. PTFE). To improve the signal / noise ratio, the measuring point is electrically shielded and the measuring signal is amplified. Micro process technology offers a lot of potential for the intensification of chemical, biochemical and pharmaceutical production. MicroDetec is protected by an international patent application. A first operating prototype has been built. PROvendis is offering licenses for the invention to interested companies on behalf of the TU Dortmund. There is also the possibility of collaboration with the inventors. 16.07.2015 | nachricht Read more

Fall detection system (Apparatus and Method)

The invention describes a method to detect falls with the help of air pressure sensors. The sensors are attached to the patient’s body facing different directions in order to detect the dynamic pressure caused by a fall. At the same time those parts of the protection equipment protecting the specific part of the body that is likely to experience an impact based on the dynamic pressure are activated. 16.07.2015 | nachricht Read more

Process to improve the properties of sputtered metal oxide layers

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 14.07.2015 | nachricht Read more

Vibrational analysis unveils car body defects

The invention describes a method to use of operating vibrations to determine the static stiffness of e.g. car bodies. 07.07.2015 | nachricht Read more

Binary group-15 compounds as precursors to manufacture group 13-15 semiconductor layer stacks

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. 06.07.2015 | nachricht Read more

Method for protein production in microalgae

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. 06.07.2015 | nachricht Read more

Process for producing porous carbon

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. 06.07.2015 | nachricht Read more
