A modern fuel cell is usually made of a stack of individual cells that are mechanically pressed together.

Climate-neutral steelmaking

Novel raw material input for the production of green steel. In addition to hydrogen, a carbon-containing aerosol is used to produce green steel.


SoSiCon is a project that is intended to contribute to the energy turnaround. It would solve two problems of wasting resources at the same time. It combines inexpensive and efficient solar thermal energy storage with the refinement of desert sand into commercially usable construction sand. This combination reduces the stress on the system by selectively overheating the storage medium (sand). The resulting reduction in operating costs for the provision of energy, together with the increased revenue from the sale of the building sand, promises a rapid amortization of the plant.

Hock rearrangement

The present invention is an environmentally friendly process as a substitute for common synthesis routes for sulfuric acid-free phenol and acetone synthesis.

Quantum Dot Arrays

Nanostructures are suitable for the fabrication of optoelectronic devices, but their fabrication is costly. Their utility, however, is immense: mode profiles can be created in a direct way, for example, to "attract" lasers or to adjust densities for single quantum dot applications such as single photon sources.

Spray freeze-drying

Spray freeze-drying combines the advantageous properties of the well-established techniques spray drying and freeze-drying.

Plasma Biocatalysis

Enzymatic reactions offer the possibility to synthesize new molecules with high selectivity and turnover.

Color flop effects without interference pigments

It is an innovative, cost-effective application method for the creation of color flop effects by means of effect pigments without costly interference pigments.

Determination of the degree of curing of a coating

The method is based on the fact that the polymer network in a cured coating is denser than in a coating that is less cured. It concerns a method by which chemical cross-linking and thus suitability for further processing can be determined for a system of coatings.
