Breakthrough non-toxic method developed to extract gold from e-waste

The water-based extraction process could revolutionize mining and recycling industries
Forward-looking: A team of Australian researchers has unveiled a breakthrough method for extracting gold that could dramatically reduce the environmental and health hazards long associated with mining and electronic waste recycling. The innovation, developed at Flinders University, offers a safer and more sustainable alternative to the use of toxic chemicals like mercury and cyanide, which have historically dominated the gold recovery industry.

Researchers develop nano-thin gold coating to prevent glass from fogging up

Ideal for eyeglasses and windshields
In a nutshell: Researchers at ETH Zurich have spent the last few years perfecting a coating capable of passively preventing fogging on glass surfaces. Their latest iteration consists of extremely thin clusters of gold situated between ultrathin layers of titanium oxide on the top and bottom. The resulting coating is able to absorb a portion of infrared radiation from the Sun, which heats up the surface by as much as eight degrees Celsius and prevents condensation from forming.
