Device and process for the agglomeration of colloids

This invention provides a device for the agglomeration of very finely distributed solids, colloids, or fibres, especially in elutriates, pasty goods, fine particle systems, and/or liquids (pelletization equipment) with alternative reactor geometry and a new reactor design that makes it possible to improve the agglomeration of suspended particles (with a size of > 1 µm) and to increase throughput of treatable substances, such as sludge or slurry. 29.07.2015 | nachricht Read more

Method for rapid optimization of FEBID/FIBID processes

Localized conducting nanostructure fabrication by bottom-up approaches, such as focused electron or ion beam induced deposition (FEBID/ FIBID) or selective-area atomic layer deposition (SA-ALD), are more and more frequently used in different application fields. Researchers from the Goethe University Frankfurt am Main have developed a semi-automatic electrical conduction optimization process for these bottom-up techniques. The process is fully customizable, highly efficient and fast. 29.07.2015 | nachricht Read more

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

Im Focus: Glaciers melt faster than ever

Glacier decline in the first decade of the 21st century has reached a historical record, since the onset of direct observations. Glacier melt is a global phenomenon and will continue even without further climate change. This is shown in the latest study by the World Glacier Monitoring Service under the lead of the University of Zurich, Switzerland.

The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years. Together...
