Researchers at Chalmers University of Technology, Sweden, have developed a new material that prevents infections in wounds – a specially designed hydrogel, that works against all types of bacteria, including antibiotic-resistant ones. The new material offers great hope for combating a growing global problem.
The World Health Organization describes antibiotic-resistant bacteria as one of the greatest threats to global health. To deal with the problem, there needs to be a shift in the way we use antibiotics, and new, sustainable medical technologies must be developed.
“After testing our new hydrogel on different types of bacteria, we observed a high level of effectiveness, including against those which have become resistant to antibiotics,” says Martin Andersson, research leader for the study and Professor at the Department of Chemistry and Chemical Engineering at Chalme

As more vehicles are designed to run on electricity, and especially as batteries are required to provide longer ranges, the weight of the batteries becomes more of an issue. In some cases, the battery pack could contribute 20-25 percent of the total mass of the electric vehicle (EV). The need for massless energy storage is growing.
Researchers at Chalmers University of Technology in Sweden saw this challenge as an opportunity to turn some of the car’s structural components into batteries themselves, effectively eliminating much of the battery weight as it becomes part of the vehicle itself.
The structural battery, designed by Professor Leif Asp’s team at Chalmers University, combines carbon fiber as a negative electrode, and a lithium iron phosphate-coated aluminum foil as the positive electrode, separated by a glass fiber separator in a structural battery electrolyte matrix material. The carbon fiber anode and the electrolyte support structural loads and move i
