Soon, Air Pollution Could Be Measured on Every Street Corner

June 13, 2019 By Chalmers University of Technology

Air pollution is responsible for 550,000 premature deaths a year in Europe and 7 million worldwide, according to the WHO. Measuring it can be a challenge, however, as the equipment tends to be large and expensive. But soon, this may change, thanks to a small, optical nanosensor developed at Chalmers University of Technology, Sweden, which […]

World’s Fastest Hydrogen Sensor Could Pave the Way for Clean Hydrogen Energy

April 12, 2019 By Chalmers University of Technology

Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers from Chalmers University of Technology, Sweden, present the first hydrogen sensors ever to meet the future performance […]

Carbon Fiber Can Store Energy in the Body of a Vehicle

October 18, 2018 By Chalmers University of Technology

A study led by Chalmers University of Technology, Sweden, has shown that carbon fibres can work as battery electrodes, storing energy directly. This opens up new opportunities for structural batteries, where the carbon fibre becomes part of the energy system. The use of this type of multifunctional material can contribute to a significant weight-reduction in […]

Untapped Gold Mine is Lost From End-of-Life Vehicles

March 6, 2018 By Chalmers University of Technology

Vast quantities of scarce metals are being lost from Europe’s urban mine of vehicles, including 20 tons of gold each year—and the proportion of critical metals in vehicles is continuing to increase. A database is now being published that charts the metals and facilitates recycling. On 8 March Maria Ljunggren Söderman, researcher at Chalmers University […]
