A little amount of appropriately prepared powder is poured in water polluted with phenol and cellulose. A bit of the sun and after fifteen minutes harmful compounds disappear, and the powder can be filtered off and reused. Sounds like a fairy tale? Perhaps, but it is not magic, only a masterly use of chemistry and physics by researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw.
Creating sustainable cities requires technical, organizational and financial innovations, in order both to organize urban systems and to establish key business models. These are created when stakeholders collaborate across disciplines to bring creative approaches to new technologies. Fraunhofer's 'Morgenstadt - city of the future' initiative provides the space required to facilitate this kind of innovation and active work.
The use of solar panels to produce toilets hot water is standard practice, but researchers at the Madrid Universities Carlos III and Politécnica suggest that they may also be used to provide large offices with heating in the winter and air conditioning in the summer.
European Union Member States are showing mixed progress towards three climate and energy targets for 2020, even though the EU as a whole could reduce greenhouse gases emissions by 21% in 2020 with the set of national measures already adopted. These findings come from new European Environment Agency (EEA) assessments.
In a time when Australia's liquid transport fuel supplies are declining and our transport needs are growing, a research partnership between Australia and India could provide a solution to a number of energy concerns and ultimately reduce the reliance of both countries on imported fuels.
The seesaw variability of global temperatures often engenders debate over how seriously we should take climate change. But within 35 years, even the lowest monthly dips in temperatures will be hotter than we've experienced in the past 150 years, according to a new and massive analysis of all climate models. The tropics will be the first to exceed the limits of historical extremes and experience an unabated heat wave that threatens biodiversity and heavily populated countries with the fewest resources to adapt.
