Constructed wetlands in planned communities can aid in surface water cleanup and flood prevention, according to Purdue University scientists who completed a five-year study on the management system.
The research, begun in 1998 on three constructed ponds, or wetland cells, on a newly renovated golf course on the university campus, showed that 11 of 17 measurable chemicals in surface water were reduced after running through the system, said Ron Turco, soil microbiologist and senior author of the report. Study results are published in the February issue of the journal Ecological Engineering. "Golf courses are a perfect place for constructed wetlands used as part of a water management system because wetlands can filter chemicals out of surface water, and they can also store excess water during storms," Turco said.
In addition, constructed wetlands act as a holding area that can provide recycled water for irrigation, a system the scientists used on the golf course, he said. "Constructed wetlands on golf courses and in planned communities are a very good water management system," Turco said. "When you build houses, roads and driveways, lots of hard surface is added, leaving no place for water to go. Building dikes and levees just moves the water problem somewhere else, causing flooding elsewhere."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
