Seated on the University of Leicester’s Space Research Centre rooftop, the novel instrument captures the sun’s rays and uses them to build up a daily picture, in 3-D, of the city’s air pollution. Just the size of a suitcase, the instrument has nine telescopes that protrude out and point in different directions across the city, collecting the sunlight every minute of every day. The trapped sunlight is bounced by mirrors inside the instrument straight into the mouth of a device that measures its properties. These are then used to work out how much light has been absorbed by air pollutants before reaching the instrument.
Crucially for Leicester, the instrument can measure levels of nitrogen-dioxide in the air, a pollutant produced by traffic and one which poses a particular problem for the air quality in the city centre.
Dr Paul Monks, lead scientist on this project said, "90% of the nitrogen dioxide problem in Leicester is attributable to road traffic. Because our instrument looks at the whole city, it can identify when and where the pollution hotspots will occur during a typical day." He added, "The level of detail we have seen is remarkable. For example, one Saturday we could pin-point the cause of air pollution to a football match, owing to the increased volume of traffic. On hot, sunny days when the air is still, such pollution could pose real health problems to residents".

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
