Studies on effectiveness and on minimum requirements
Within the scope of a research project, the Oel-Waerme-Institut examines the effectiveness of mineral oil additives and their fulfillment of minimum requirements (no-harm-criteria) in additized fuels.
Additives serve quality assurance and fulfill specific functions, for instance by improving the oxidation stability of mineral oil products or by protecting metallic surfaces against corrosion.
The focus is on the question to what extent the increasing diversification and aging processes of fuels during their storage affect the effectiveness of additives or even have negative effects due to unexpected interactions.
Based on studies, measures shall be derived to improve existing additives and to develop new ones. The results could contribute to increase the operational safety of technical systems, such as heating oil systems and engines.
When placed on the market, fuels fulfill standardized characteristics, which are partially adjusted with additives. In technical systems, fuels are subjected to heavy load, which lead to aging and by that to a change in their characteristics.
The normed characteristics might no longer be complied and, in rare cases, unexpected malfunctions may occur. Analyses that reflect the current state of the fuels are anchored in fuel standards, so that an assessment of the behavior of additives and fuels during operation is not possible.
The current technical, economic and scientific questions affect the mineral oil industry, the bio fuel industry, the raw material industry, the burner industry and the automobile industry.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
