A tiny layer of graphene flakes becomes a deadly weapon and kills bacteria, stopping infections during procedures such as implant surgery. These are the findings of new research from Chalmers University of Technology, Sweden, recently published in the scientific journal Advanced Materials Interfaces.
Working up a sweat from carrying a heavy load? That is when the textile works at its best. Swedish researchers have developed a fabric that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes the more electricity it generates. The results are now published in the Nature Partner journal Flexible Electronics.
Researchers at Chalmers University of Technology have shown that between 87 and 98 percent of ships comply with the tougher regulations for sulphur emissions that were introduced in northern Europe in 2015. The lowest levels of compliance were observed in the western part of the English Channel and in the middle of the Baltic Sea.
Vast quantities of scarce metals are being lost from Europe’s urban mine of vehicles, including 20 tonnes 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 Chalmers researcher Maria Ljunggren Söderman will present the results at IEA’s expert meeting.
“Something else that’s becoming big, and I think is going to be very important in the future, is so-called ‘biosensing’. Graphene conduct...

Traffic noise is the second biggest environmental problem in the EU, according to WHO. After air pollution, noise is affecting health the most. But legislation regarding noise pollution is insufficient. A new report shows how negative health effects of noise can be reduced. Several means are easiest to apply in dense cities.
