Scientists create lightweight 18-carat gold using ordinary plastic

Researchers with ETHzurich have successfully used plastic to create lightweight gold that retains its purity, according to a recent announcement from the institution. The lightweight gold is ideally suited for products like jewelry and watches — things that would benefit from a reduction in weight without a loss in gold purity or beauty.

The gold found in jewelry is made with metallic alloys that help reduce the weight, though some pieces of jewelry may still be too heavy to suit some buyers. The newly created 18-carat gold replaces the metallic alloy elements with a ‘matrix of plastic,’ reducing the density from a typical 15 g/cm3 to 1.7 g/cm3.

The dollar will be replaced by gold and cryptocurrency by 2040

Fiat money will lose its significance to gold and the cryptocurrencies in the next twenty years, said Robert Kiyosaki, bestselling author of “Rich Dad Poor Dad” and his latest ,”Why The Rich Are Getting Richer.”

The self-proclaimed gold bug is one of few investors to be bullish on both bitcoin and gold, noting that the cryptocurrency will slowly erode fiat currencies’ relevance, while gold will act as an important hedge instrument.

Chemists developed a method of artificial photosynthesis, and proved it by turning gold atoms into purple-colored nanoparticles.

Professor Richard Watt and his chemistry students suspected that a common protein could potentially react with sunlight and harvest its energy – similar to what chlorophyll does during photosynthesis.

Nylgold

Nylstar, specialist in polyamide 6.6 fibers and yarns for more than 80 years, has lately introduced a new luxury fiber called Nylgold, which they say is going to represent a new era in textiles – the era of dermawear. The Nylgold luxury fiber features 24-carat gold nanostructures, and offers permanent and effective care of the skin. It was launched at the Intertextile Shanghai Apparel Fabrics held in October at Shanghai New International Expo Centre, Shanghai, China. Raul Gonzalez, head of marketing and international strategic development at Nylstar, said… (Video)

Using Cinnamon to Produce Gold Nanoparticles

Cinnamon

Cinnamon can be used as a replacement for toxic chemicals in the production of gold nanoparticles.

A humble spice found in nearly every kitchen could yield a safer, simpler way to produce gold nanoparticles, according to a new study. Researchers say the cinnamon-infused particles can even be used to fight cancer.

An Implantable Biosensor Could Alert Doctors to Signs of Disease

silk biosensor

A biosensor made from silk and gold can pick up tiny signals from proteins and chemicals in the body.

Silk and gold, usually a pairing for the runways of Milan, are now the main ingredients for a new kind of implantable biosensor. Researchers at Tufts University have crafted a small antenna from liquid silk and micropatterned gold. The antenna is designed to spot specific proteins and chemicals in the body, and alert doctors wirelessly to signs of disease. Scientists say the implant could someday help patients with diabetes track their glucose levels without having to test themselves daily.

20x More Energy From Sewage…By Adding Gold?

sewage-plant2678
An energy bonanza?

Sewage is a surprising resource when it comes to harvesting energy during its treatment. According to researchers from Oregon State University, investing a little more in sewage could provide substantially bigger yields. They’ve found that adding gold nano-coatings to the anode chamber of a fuel cell could help produce 20 times more electricity from sewage treatment. The findings could mean bid news for combining wastewater with renewable energy generation.
