New Lithium Salts of Pentafluorophenylamide Anions as Electrolytes in Lithium Ionic Batteries

The invention provides novel lithium salts of pentafluorophenylamide, in particular, lithium pentafluorophenyl (trifluoromethylsulfonyl)imide (Li-PFTFSI). Li-PFTFSI has improved thermal stability and ion mobility compared to known lithium salts. These characteristics make Li-PFTFSI desirable for use as electrolytes in lithium ion batteries. 18.04.2017 | nachricht Read more

Gratings on glass surfaces

The newly developed method aims at producing small gratings on different materials, especially on glass surfaces, by ablating small amounts of material. The gratings can be small enough to form patterns with a diffractive effect causing the material to schiller in different colors. 28.03.2017 | nachricht Read more

Oligomeric vaccines

Immunization is an important tool to fight diseases caused by viral, bacterial or fungal pathogenes. The invention provides a new approach for the generation of oligomeric vaccines. The underlying principle is the high affinity interaction between S-protein and a modified S-tag of bovine pancreatic RNase A which is applied to hemagglutinin (H5). The technology can be applied to produce high molecular vaccines. They have many advantages compared to recently used vaccines including high immunogenicity, high stability, short production time and lower production costs. The approach could therefore be used for the immunization of livestock. 27.03.2017 | nachricht Read more

Flexible and rigid, heavy-metal free organic redox polymer batteries

Traditional battery materials, e. g. for Li-ion batteries are brittle, thus not suitable for high capacity flexible batteries. Rigid organic redox polymer batteries have low volumetric energy and power density. Using a new colloid consisting, of redox pol-ymer and graphene oxide that is trans-formed into reduced graphene oxide during preparation, thickness scalable cathodic and anodic battery materials reaching 1.3 mAh/cm2 for flexible and at least 21 mAh/cm2 for rigid materials are available. The new technologa offers the following advantages: higher capacities materials for flexible batteries, scalability 1 – 20 mAh/cm2, tailord redox-potential and non-toxic materials. 09.03.2017 | nachricht Read more

Quat primer polymers – the universal key to permanent surface functionalization

"Q-primers" are ammonium compounds, which make it possible to permanently functionalize virtually any surface. It is an environmentally friendly and cost-effective process that allows the production of ultra-thin layers and an "on demand" functionalization. The carrier quat primer can be equipped with any functional groups so that an universally applicable strategy for the modification of surfaces is now available. 27.02.2017 | nachricht Read more

Asian plant helps against the Ebola virus

A herbal remedy is effective against the Ebola virus. The natural compound silvestrol reduces the number of pathogens in infected cells. Also the production of virulent proteins is largely suppressed if the natural substance is used. 20.02.2017 | nachricht Read more

Novel carbonization process of PAN-nanofiber mats with enhanced surface area and porosity

This innovative carbonization process of carbon precursor fibers creates in a fast and energy saving manner carbon fibers (CF) which are highly porous (small pore diameters from 0.1 to 10 nm) and have a high surface area (100 to 2500 m2/g). The pyrolysis step needs only minutes or even seconds. No additional additives like pore-providing templates, catalytic compounds or corrosive liquids are required. However, filler materials like pigments, dyes, graphene nanoplatelets or metal- and semiconductor nanoparticles can be admixed to vary the performance of the produced carbon fibers, e.g. to increase electrical conductivity. Overall, this technology combines conventional carbonization and activation treatments into one process and is more economical by saving time, costs and resources compared to already known thermal carbonization methods. Applications of carbon fibers are known in the art. Electric applications like super caps and electrodes or filtration and adsorption for gas, water and solvent purification might be preferable. 20.02.2017 | nachricht Read more

MCR Dendrimers

Dendrimers are spherical, highly branched polymers used in the fields of drug delivery and drug targeting, DNA/RNA delivery, imaging, protein labelling, protein crosslinking and protein separation, coagulation inhibition, and surface, cell and tissue recognition. They are also used as macroamphiphiles and catalyst supports. All previously existing dendrimers require special, branched and partially protected or polyreactive building blocks for their synthesis. A disadvantage is the limited range of dendrimers with varying structures that can be produced, and the concentration to few dendron forming functional groups. The new technology offers the possibility of synthesising dendrimers with almost any combination of branch lengths, degree of branching, internal and terminal groups. This is achieved by means of multiple iterative multicomponent reactions, e.g. with acidic, alkaline, hydrophilic, lipophilic, sugar and other functional groups. 10.02.2017 | nachricht Read more

Low cost cloning

DNA assembly methods such as such as Gibson and Golden Gate cloning are basic tools for synthetic biology. Both methods allow assembly of constructs from multiple DNA fragments in a one-pot one-step assembly reaction. Standardization of parts is another essential element of modern synthetic biology. A novel method has been developed to assemble constructs from several individual DNA parts - each kept on a solid carrier - directly in a one-pot one-step reaction. 10.02.2017 | nachricht Read more

Parenteral controlled drug delivery - oleogels

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. Direct Injectable OleoGels (DIOGs) and In Situ Forming OleoGels (ISFOGs) were developed as new, biodegradable and lipid based formulations for parenteral controlled release applications. Both formulations have many advantages in terms of manufacturability, rheological properties and release control compared to the currently used drug delivery systems. 10.02.2017 | nachricht Read more

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...

Im Focus: Magnets for the second dimension

If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.

Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...

Im Focus: Distorted Atoms

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.

An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
