Completed development projects
A method for separating fatty acids from an aqueous medium by means of open-pored membranes has not previously existed. A method was developed to dissolve fatty acids in aqueous media using a biomolecule. A membrane was developed for the separation of dissolved fatty acids from aqueous media, with which a selective electrophoretic transport of fatty acdes is made possible. The established membrane technology for the separation of carboxylic acids can be used in various life science areas (e.g. medicine, chemistry or environmental technology).
When living cells come into contact with artificial surfaces, an immunological reaction occurs. This can lead to undesirable reactions. Such a reaction can be reduced or prevented by coating with biogenic compounds. One of these classes of compounds are nitro fatty acids. It has been found that coatings with nitro fatty acids are very suitable, for example, to suppress the immunological reactions that occur in the human body with implants. The problem was that nitro fatty acids, which can easily be applied to artificial surfaces, detach from them again when they come into contact with body fluids. A coating technology was developed in which a bio-degradable polymer can be applied to artificial surfaces in the form of a thin film, which continuously supplies nitro fatty acids to the surface over the duration of the biodegradation. At the same time, the coating protects against corrosion / decomposition of the coated material by aqueous media (e.g. blood or tissue fluids). In this way, on the one hand, a significant improvement in the biocompatibility of implant materials can be achieved and, on the other hand, the corrosion / degradation of implant materials can be influenced.
Up to now there has not been a device with which it is possible to heat or control the temperature in particular of small amounts of liquids that are present in any non-metallic vessel without using a cable-connected heating device for this purpose. A method and devices have been developed with which it is possible, for example, to heat a drink in a paper cup to the exact degree and keep it at the preselected temperature without having to heat the vessel or inserting a heating device inton the liquid. For this purpose, a method has been developed with which a heating element, which is inserted into a non-metallic vessel filled with a liquid, is inductively heated, whereby the temperature of the liquid in the vessel and the surface temperature of the heating element are determined at the same time, and thus individually adaptable heating and temperature control in any type of non-metallic vessel can take place. The input of thermal energy is very energy-efficient, since only the medium in which the heating element is located is heated and thus takes place by direct input of energy. In this way, for example, such a device can be installed and operated in a motor vehicle, as a result of which, for example, coffee in a disposable cup can be kept at a selectable temperature over the entire duration of consumption.
