Researchers detect broad range of emerging synthetic antioxidants in dust in e-waste recyling centers

Green Car Congress

An open-access paper on the work is published in ACS’ Environmental Science & Technology Letters. Now, researchers have detected a broad range of emerging synthetic antioxidants, called hindered phenol and sulfur antioxidants, in dust from electronic waste (e-waste) recycling workshops, possibly posing risks for the workers inside.

UMD, Army Researchers design new electrolyte enabling high energy density rechargeable Mg and Ca batteries

Green Car Congress

A paper on their work is published in the journal Science. The researchers also found they could apply the same design principle to other materials that fall under the category of divalent metals, not just magnesium. It’s the first time a magnesium battery theoretically reached a similar energy density as a lithium-ion battery.

Disruption, Disrupted

Cars That Think

The Nature study divides innovation into two categories: disruptive concepts that make old technologies obsolete and concepts that consolidate knowledge based on existing technologies. Many studies had credited disruptive ideas with causing the explosive growth of science and technology since the mid-20th century.
