Comments Off on New biodegradable semiconductor could make e-waste a thing of the past

50 million tons of electronics are expected to be trashed this year, according to a United Nations Environment Program report . A Stanford University team was concerned over the escalating epidemic of e-waste , so they created a semiconductor – a component in most of our electronics – that can actually be broken down with a weak acid such as vinegar. Nine Stanford researchers, joined by one scientist from Hewlett Packard Labs and two engineers from the University of California, Santa Barbara , set out to rethink electronics. Engineer Zhenan Bao, who heads up the Bao Research Group at Stanford, said they found inspiration from human skin . Skin stretches, can heal itself, and is ultimately biodegradable . The researchers wanted to take these characteristics and apply them to electronics. Related: INFOGRAPHIC: The dangerous untold story of e-waste They created a flexible polymer able to decompose. Postdoctoral fellow Ting Lei said it’s the first ever “semiconductive polymer that can decompose.” But that’s just one part of a semiconductor. The team also designed a degradable electronic circuit and a biodegradable substrate material. They used iron – a nontoxic, environmentally friendly product – instead of the gold usually used for electronic components. They made a paper-like substrate with cellulose ; the transparent substrate allows the semiconductor to adhere to rough or smooth surfaces, like onto an avocado as seen in the picture above or on human skin. The semiconductor could even be implanted inside a body. According to Stanford, “When the electronic device is no longer needed, the whole thing can biodegrade into nontoxic components.” The team envisions a number of uses for their semiconductors, like in wearable electronics . They could be made into patches allowing people to track their blood pressure, for example, or could be dropped via plane into a forest to survey the landscape, and eventually they would biodegrade instead of littering the environment . The journal Proceedings of the National Academy of Sciences of the United States of America published the research online the beginning of May.

Yarr, if it’s gold you be seeking, to England you should go: a German artist has buried $16,000 worth of gold bullion in the sand of the Outer Harbour beach in Folkestone, which people can come and search for this Thursday as part of the Folkestone Triennial . As part of an art project entitled Folkestone Digs , Michael Sailstorfer has buried the 30 bars of gold bullion under the sand of the beach as part of a participatory art project which he hopes will attract many people to the area at low tide on Thursday, Sept. 4 to search for it. “It’s about people coming to the beach and digging and possibly finding hidden treasure,” Triennial curator, Lewis Biggs told The Guardian . “Some people will get lucky, some people will not get lucky – and that’s life.” Read the rest of Artist Buries $16k Worth of Gold Bullion that People Can Find and Keep Permalink | Add to del.icio.us | digg Post tags: Art , Artist , beach , buillion , buries , Folkestone , GOLD , michael , project , sailstorfer , situations , triennial

Comments Off on 16-Year-Old Creates Cancer-Killing Nanoparticle Bullet

In the battle to beat cancer, everyone is looking the elusive silver bullet. In this case, the bullet may actually be made of gold, and it has been developed by a 16-year-old. Indian-born Arjun Nair has been awarded a $5,000 prize from the Ottawa headquarters of the National Research Council of Canada for his work as part of the 2013 Sanofi BioGENEius Challenge Canada (SBCC). Using the experimental method of Photothermal therapy (PTT), the nanobullet he devised would inject cancer-killing gold particles to seek out and destroy the harmful cells.

Comments Off on Scientists Discover New Technique To Change the Color of Gold Without Using Chemicals

Photo by  Shutterstock Researchers at the  University of Southampton  have developed a new way to alter the color of gold—or just about any metal—  without  chemically altering it. The technique involves “nano-patterning” — etching the metal’s surface with patterns of specific shape and depth, which manipulates the wavelengths that are visible to the human eye. The technique could deliver valuable economic and environmental benefits, and it could be harnessed to manufacture jewelry and to make banknotes and documents more difficult to forge.
