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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
