As mountains of scrap tires continue to rise above the landscape, researchers at the University of Wisconsin-Madison have found an environmentally friendly use for them: grind them up and place the rubber bits beneath golf course greens.
In a paper accepted for publication in the journal Waste Management, the researchers show that these ground tires can absorb excess chemicals from fertilizers and pesticides, preventing them from leaching into groundwater and contaminating the surrounding environment.
Golf courses are designed to improve playability, not environmental impact, says Jae (Jim) Park, a professor of civil and environmental engineering at UW-Madison and an avid golfer with a 6 handicap. But, as an environmentally conscientious person, Park is also aware of the unintentional side effects of the fertilizers and pesticides applied to the golf-course greens to keep them looking, well, green. These products contain chemicals that trickle into groundwater sources and contaminate the surrounding environment, he says.
"Because many greens are built near groundwater levels or wetlands," explains Park, "it is vital to consider the mitigation of environmental contamination caused by the pesticides and fertilizers applied to golf courses."

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
