#aromatic compounds

An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds added to conventional fuels, according to new research.

In a study published in the journal Fuel, researchers analyzed a Washington State University-developed jet fuel based on lignin, an organic polymer that makes plants tough and woody.

Using a range of tests and predictions, the researchers examined fuel properties critical to jet engine operation, including seal swell, density, efficiency, and emissions. Their results suggest that this sustainable fuel could be mixed with other biofuels to fully replace petroleum-derived fuels.

"When we tested our lignin jet fuel, we saw some interesting results," said Bin Yang, professor with WSU's Department of Biological Systems Engineering and corresponding author on the study. "We found that it not only had increased energy density and content but also could totally replace aromatics, which are a real problem for the aviation industry."

Metallic five-membered ring pushes the boundaries of aromaticity

Researchers at Chemnitz University of Technology, Humboldt Universität Berlin and Philipps-Universität Marburg succeed in synthesizing a molecule that should not actually exist.

How many atoms can an aromatic ring have if it contains only two electrons? The answer has recently been changed: five! For the first time, a team from chemistry has succeeded in synthesizing and describing a five-membered aromatic compound—an important class of substances in chemistry—by combining experiment and theory. They have thus achieved what had been attempted for decades and had been considered impossible in the meantime. The research groups led by chemistry professor Dr. Robert Kretschmer from the Chemnitz University of Technology, Dr. Oliver Dumele from the Humboldt University Berlin and chemistry professor Dr. Florian Weigend from the Philipps University in Marburg report on their findings in the journal Angewandte Chemie International Edition.
