Emissions from cars have to be reduced further in order to meet today’s environmental demands. A new and robust exhaust sensor developed by researchers at Linköping University in Sweden has proven to meter the consistency of exhaust gases extremely well and is now on its way to the market.
It’s a tiny electronic component, no larger than the head of a pin. It has been tested both at LiU and in cars at its collaborating auto-makers, Volvo Cars in Gothenburg, Sweden, and Ford Motor Company in Detroit, Michigan. The results are reported in a dissertation by Helena Wingbrant, a doctoral student at the S-SENCE center of excellence.
The component is used to meter the amount of air in the fuel mixture, or the content of ammonia in diesel exhaust. The former is important to be able to reduce emissions from gasoline cars during cold starts, the latter to regulate the exhaust purification system that is under development for diesel cars. The sensor has proven to perform these tasks extremely well-so well that the Linköping company AppliedSensor now wants to take it to market.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
