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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
