Test of the no-harm-criteria of additives


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.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
