Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which is a cause for concern, according to a group of environmental scientists that recently carried out the first major study of soybeans grown in soil contaminated by two manufactured nanomaterials (MNMs). The team was led by scientists at UC Santa Barbara's Bren School of...

'A huge step forward in the safety screening of nanomaterials,' researchers say Engineered nanomaterials, prized for their unique semiconducting properties, are already prevalent in everyday consumer products – from sunscreens, cosmetics and paints to textiles and solar batteries – and economic forecasters are predicting the industry will grow into $1 trillion business in the next few years. But how safe are these materials? Because the semiconductor properties of...

With the curtain about to rise on a much-anticipated new era of "nanoagriculture" – using nanotechnology to boost the productivity of plants for food, fuel, and other uses – scientists are describing huge gaps in knowledge about the effects of nanoparticles on corn, tomatoes, rice and other food crops. That's the topic of the latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series. Jorge Gardea-Torresdey,...

Nanotechnology refers to a broad range of tools, techniques and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter. Particles of this size have some unique physicochemical and surface properties that lend themselves to novel uses. Indeed, advocates of nanotechnology suggest that this area of research could contribute to solutions for some of the major problems we face on the global scale such as ensuring a supply of safe...

As researchers around the world hasten to employ nanotechnology to improve production methods for applications that range from manufacturing materials to creating new pharmaceutical drugs, a separate but equally compelling challenge exists. History has shown that previous industrial revolutions, such as those involving asbestos and chloroflurocarbons, have had some serious environmental impacts. Might nanotechnology also pose a risk? Linsey Marr and Peter Vikesland, faculty members in the Via...

The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health. However, little is known which particles may be harmful. Part of the problem is determining exactly what a nanoparticle is. A new analysis by an international team of researchers from the Center for the Environmental Implications of NanoTechnology (CEINT), based at Duke University, argues for a new look at the way nanoparticles are selected when...

Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
