Polymer-coated catalyst protects 'artificial leaf'

Researchers have modified so called superstrate solar cells with their highly efficient architecture in order to obtain hydrogen from water with the help of suitable catalysts. But the solar cell rapidly corrodes when placed in the aqueous electrolyte solution. Now, they have found a way to prevent corrosion by embedding the catalysts in an electrically conducting polymer and then mounting them onto the solar cell's two contact surfaces.

Generating wind energy from kites

The electricity from our sockets could soon come from a high-tech device flying in the sky. The innovative research project to generate wind energy with the aid of a kite won over the 'Venture Kick' jury; it is providing CHF 10,000 of support for the Empa spin-off 'TwingTec'.

Researchers design a catalyst that neutralizes the gases responsible for climate change

This new technology, developed by the Research Group in Carbon Materials and Environmental allows, through a catalytic system active, efficient and stable over time, to eliminate nitrous oxide decomposing it into nontoxic products, purifying the gases emitted by industries related to the production of fertilizers, plastics and coal burning plants to produce electricity or vehicles.

Wood not so green a biofuel

Using wood for energy is considered cleaner than fossil fuels, but a Dartmouth College-led study finds that logging may release large amounts of carbon stored in deep forest soils.

Common sense won't help you understand climate

Unfortunately, many of the systems we need to understand, such as the climate, ecosystems and financial markets, are complex. Complex systems often behave in very nonlinear ways, meaning that common sense and intuition fail.
