Removing toxic mercury from contaminated water

Mercury can seep into water supplies from improperly discarded devices containing it, as runoff from landfills & farmland, dumped by factories, or from natural...
The energy system MOST works in a circular manner. First, the liquid captures energy from sunlight, in a solar thermal collector on the roof of a building. Then it is stored at room temperature, leading to minimal energy losses. When the energy is needed, it can be drawn through the catalyst so that the liquid heats up. It is envisioned that this warmth can then be utilised in, for example, domestic heating systems, after which the liquid can be sent back up to the roof to collect more energy -- all completely free of emissions, and without damaging the molecules.

Emissions-free energy system saves heat from the summer sun for winter

Scientists at the Chalmers University of Technology, Sweden have designed molecule which can store solar energy for later use. Scientists have built up a catalyst for...
Fischbrötchen, Fish

Fish consumption could prevent Parkinson’s disease

Fish has long been considered a healthy food, linked to improved long-term cognitive health, but the reasons for this have been unclear. Omega-3 and...

Graphene spikes can kill bacteria on implants

Surgical implants, for example, hip and knee substitutions or dental implants involves a major risk of bacterial disease. In the direct outcome, this can...

Electric textile lights a lamp when stretched

Researchers at the Chalmers University of Technology have developed a fabric that converts kinetic energy into electric power, in cooperation with the Swedish School...
