Parenteral controlled drug delivery - polymers

Parenteral controlled drug delivery is of crucial importance for the pharmacotherapy of many diseases (e.g. breast and prostate cancer, local inflammation). By means of controlled release systems it is possible to decrease the frequency of administration (from hours to months), to increase drug efficiency and to decrease side effects. The problem is solved by providing Direct Injectable Polymer Solutions (DIPOs) which act as a depot after administration. Their polarity and degradation rate is adjustable. They are much less acidic compared to PLA/PLGA polymers. 10.02.2017 | nachricht Read more

Barley yellow mosaic virus

Yellow mosaic virus disease leads to substantial losses - up to 50 % of the yield - in susceptible barley varieties (Hordeum vulgare). The disease is caused by different strains of Barley yellow mosaic virus (BaYMV) and Barley mild mosaic virus (BaMMV). It cannot be cured by chemical treatment. The present invention provides a new recessive resistance gene. Variants of the gene lead to resistance against all agents known to cause yellow mosaic virus disease in Europe. 10.02.2017 | nachricht Read more

Night Vision Algorithm

The Technology provides a new and outstanding method for the enhancement of the quality of dim images. Inspired by the spatial integration of visual information in nocturnal insects, the algorithm successfully enhances the contrast and brightness of dim images and removes noise while preserving fine details and object contours. The patented system is applicable to field programmable gate arrays (FPGA) or image processors, which offer parallel computing capabilities. A wide variety of capabilities and markets from automotive sector to the enhancement of diagnostic images can be addressed. 08.02.2017 | nachricht Read more

Quantification of hydrogen - method that uses a flame ionization detector to dermine hydrogen

The Carl von Ossietzky University in Oldenburg, Germany, developed a method which markedly improved the quantitative determination of hydrogen. A so-called TPR is conducted by coupling a flame ionization detector (FID) to a methanizer. Adding a certain amount of carbon monoxide (CO) and an excess amount of hydrogen immediately upstream of the FID, CO will react with hydrogen to yield methane. Methane produces a FID signal which is proportional to the amount of hydrogen in the sample. 07.02.2017 | nachricht Read more

Multisensor system - optical device to analyze liquid media

As yet there has been no satisfactory and easy method to determine the concentrations of substances dissolved in liquid product flows. Previous methods using sensors were not sufficiently reliable and not designed for flow-through systems. Or they required that the analyte whose concentration was to be determined was already known. The device according to invention makes it easy to determine the analyte in a liquid phase both qualitatively and quantitatively. The Carl von Ossietzky University in Oldenburg, Germany, developed a method which serves the purpose of identifying and quantifying substances (proteins, amino acids, drug constituents) in solution. 07.02.2017 | nachricht Read more

Anemometers to measure microturbulences

Researchers from the University of Oldenburg, Germany, developed a laser cantilever anemometer (LCA) which utilizes the laser pointer principle of a scanning-force microscope to capture the velocity and the angle of fluid flows. 07.02.2017 | nachricht Read more

Adjustable flaps for wind turbines

Researchers at the University of Oldenburg have developed a flap for wind turbine generators which is mounted parallel to the main rotor blade and is considerably smaller in its size and mass than the main blade. The core piece of the invention is the adjustable pitch of the flap. The flap's pitch as well as its distance to the main blade can be swiftly adjusted to actual wind variations by means of a control unit or adaptive mechanics, thus assuring an optimal airflow at the site of the main rotor. The flap adjustment unit is able to consider the position of the main blade, the actual rotor rotation speed, and the actual wind speed. A purely mechanical adaptive pitch adjustment is also in a state of planning. 03.02.2017 | nachricht Read more

Root sided monitoring system for laser welding

The newly developed method improves the monitoring and control process for beam welding. In contrast to most commonly used methods, the new monitoring process is root sided, i. e. it takes place on the back part of the workpiece. Furthermore, the invention describes a monitoring device optimized for beam welding. Beam welding using the invention avoids incomplete fusion at the weld interface and increases the stability of the weld joint. 02.02.2017 | nachricht Read more

Compensation of spectral fractions in transmitting units

Method for reducing cross-talk / interference: The optimal utilization of the available frequency bands plays an important role in the transmission of messages. In frequency multiplexing, sub-frequency bands are allocated to individual communication channels, which are usually completely independent of each other. In practice, however, there is cross-talk, that is, in a channel, signals from the two adjacent channels are also received. Thus, the received signal is composed of useful signal and interference signal. The aim of the present invention is to compensate for the interfering signal component. This is particularly important when the intensity of the adjacent channel signals and thus the interference signal which they contribute are greater than the actual useful signal (“adjacent channel interference problem”). 31.01.2017 | nachricht Read more

Charge flow frequency converter

Charge flow frequency converters are used when especially small electrical currents must be measured. Usually, the integrator and the comparator are connected in series. The improved method can be used anywhere where very small currents of both polarities with high dynamics are measured. 30.01.2017 | nachricht Read more

Im Focus: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
