Highly efficient heavy metal ions filter

27-Jan-2016

ETH researchers have developed a new water filtration system that is superior to existing systems in many respects: it is extremely efficient at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery. In November, Brazil experienced an ...

New research sheds light on mercury pollution in estuaries, food chain

09-Dec-2015

Two studies by Dartmouth researchers and their colleagues shed new light on mercury pollution in the waters of the northeastern United States. Mercury, which is transformed into methylmercury in water, is a global pollutant that damages human health. Most people are exposed to mercury by eating ...

TU Vienna develops light transistor

09-Jul-2013

TU Vienna has managed to turn the oscillation direction of beams of light -- simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical current. Light can oscillate in different directions, as we can see in ...

Liquid on liquid goes solid

Kiel based research group discovers nano-crystals at the interface between two liquids

12-Apr-2013

Not all liquids are mixable. Researchers from the Institute of Experimental and Applied Physics of Kiel University (CAU) have investigated chemical processes with atomic resolution at the interface between two such liquids and have made an exciting discovery. During an experiment carried out at ...

Nano-velcro clasps heavy metal molecules in its grips

Researchers develop nano-strips for inexpensive testing of mercury levels in our lakes and oceans with unprecedented sensitivity

11-Sep-2012

Mercury, when dumped in lakes and rivers, accumulates in fish, and often ends up on our plates. A Swiss-American team of researchers led by Francesco Stellacci at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and Bartosz Grzybowski at Northwestern University has devised a simple, ...

Volatile mercury from historic mirrors

24-Jul-2012

Ancient mirrors still exist which were made by applying mercury to a thin tin foil. Although their production was banned in 1886, owning one has never been prohibited. Over the years, the compound of tin and mercury (the so-called tin amalgam) corrodes or detaches from the glass, the reflection ...

Plastics in electrical waste: Disposal or recycling?

22-Mar-2012

Electrical and electronic appliances are not only made from metallic materials, but also consist of up to more than 20% of plastics in average. These are found, for example, in casings or in base materials for circuit boards. No simple task for recycling companies, which find themselves ...

Tracking down volatile mercury in the Atlantic

Marine chemists from Warnemünde identify unexpected places and seasons of higher emission

28-Oct-2011

For the first time, mercury emissions of the Atlantic Ocean were investigated by comprehensive measurements, performed under the leadership of researchers from the Leibniz Institute of Baltic Sea Research in Warnemünde. The scientists Joachim Kuss, Christoph Zülicke, Christa Pohl and Bernd ...
