Method for production of itaconic acid

Itaconic acid (ITA) - also known as methylenesuccinic acid or butanedioic acid - is one of the top 12 bio-based chemical building blocks and thus a promising platform compound for production of biofuels, chemical compounds, including e.g. detergents, and polymers, including plastics and artificial glass. Itaconic acid (C5H6O4) is an organic dicarbonic acid which is soluble in water, ethanol, and acetone. The new method for production of itaconic acid uses genes encoding for the itaconic acid biosynthesis pathway of the genus Ustilago maydis. 04.03.2015 | nachricht Read more

EPAP - Corrosion prevention in NMC-cathodes for lithium-ion batteries

Future electro-mobility concepts require advanced battery technologies. Main drawbacks today are restrictions in energy density, cycling stability, and cost. The presented invention provides a solution that helps to overcome these problems. Extensive laboratory tests have already demonstrated the advantages of the invented process for preparing lithium-ion battery electrodes. Further improvement is currently under development. PROvendis offers licenses for this invention to interested companies on behalf of the University of Muenster, Germany. 25.02.2015 | nachricht Read more

Particles for optional perfusion diagnosis

Perfusion analysis in animal models (e.g. myocardial infarction) is currently determined by using fluorescent particles or dyes that are injected into circulation. They distribute throughout all blood vessels and stain them permanently. Thus it is possible to distinguish areas that are supplied with blood and those that are not. Since the dyes are long-lasting in the tissues they interfere with subsequent methods of analysis. A model animal that is used for perfusion analytics can therefore only be used for this specific analytical method. The present invention overcomes these drawbacks by injecting non fluorescent inert particles that are the first component of an orthogonal system. After perfusion with these particles, the second component is added to frozen tissue sections of interest. Thus, perfusion analysis is solely performed on a selected tissue section, without any limitations for the remaining tissue. This approach allows a background-free subsequent tissue analysis, optimizes data harvest, is economic and reduces animal consumption. 24.02.2015 | nachricht Read more

Resonant material processing using (ultra-)short laser pulses

The invention relates to the usage of a tunable, resonant electromagnetic field for both, the targeted fabrication of structures with dimensions smaller than the used beam diameter and the targeted fabrication of ultra small particles. Therefor the electromagnetic field that is created by an ultra short laser pulse on the surface of an object is superposed with an external field to achieve a resonance rise specific to the processed material. 19.02.2015 | nachricht Read more

Flower Transport - Sealing material for bouquets in water-filled containers

The object of this invention was to develop a sealing material that allows the transport of flower arrangements in a suitable vessel with continuous liquid contact. To achieve this, a suitable transport vessel is filled with water and the flowers are placed into it. Then, a hydrophobic substance with a density of <1 g/cm3, like a suitable grease, is applied in liquid form into the vessel. The grease floats on the water surface, penetrates between the stems and solidifies. Afterwards a water-containing liquid is applied on this layer and penetrates between the stems, too. Finally it solidifies into a gel with sufficient stability. The method allows an uninterrupted supply of water, nutrients and fresh-keeping agents for the flowers. As a result, the durability of the flowers will be increased under certain circumstances. 11.02.2015 | nachricht Read more

Marker-free chromosome screening

Researchers at Reutlingen University have succeeded in developing a label-free method for the characterization of metaphase chromosomes. The method and the corresponding analysis algorithm allow for visualization of both the chemical properties (absorption) and the morphological properties (stray light) of a chromosome. Using this method, the bands and sub-bands can be characterized with high resolution. Thus, no staining is required for unambiguous identification. The technology can be integrated into all imaging methods (e.g.microscopy). 10.02.2015 | nachricht Read more

System and Method for Processing Electronic Coupons on Mobile Devices

The invention offers a method to create and use electronic coupons in a new way. The coupons can be spread both directly between smartphones and by means of social networks or by means of classical advertisement, such as posters or fliers. The value of each single coupon can be increased by sharing it, initiating a viral distribution by rewarding the users for the sharing. As each coupon is unique, statistics can be performed allowing insight on the acceptance, use and distribution ways of every used coupons, allowing insight in the own mobile couponing procedures on a new level. 09.02.2015 | nachricht Read more

Cure for CLL - Derivates of para-NO-ASA for the treatment of CLL

The present invention provides compounds acting as an effective and selective medicament for the treatment of neoplastic diseases or proliferative disorders, in particular compounds which induce selectively apoptosis of degenerated cells providing reduced side effects in living organisms. The compounds of the present invention are characterized by a high selectivity towards neoplastic cells. CLL cells show a higher sensitivity towards the compounds than PBMCs opening a therapeutic window. The EC50 for CLL cells is in the lower micromolar range. 05.02.2015 | nachricht Read more

Im Focus: Black Phosphorus Is New ‘Wonder Material’ for Improving Optical Communication

Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researchers from the University of Minnesota used an ultrathin black phosphorus film—only 20 layers of atoms—to demonstrate high-speed data communication on nanoscale optical circuits.

The devices showed vast improvement in efficiency over comparable devices using the earlier “wonder material” graphene.
