Switching protocol doubles carbon capture capacity of supercapacitors

Researchers have developed a method that doubles the amount of carbon dioxide that can be captured with a supercapacitor.1 The devices made from coconut shell-derived porous carbon, capture CO­2 as they charge, which can then be controllably released when discharging the capacitors for collection and storage. By altering the voltage applied to the supercapacitor device […]

Can negative emissions technology clear the air without costing the Earth?

Carbon Engineering and Occidental Petroleum’s subsidiary 1PointFive, have announced plans to install 70 direct air capture (DAC) plants by 2035 – each capturing up to one million tonnes of carbon dioxide a year. A first plant is expected to be operating by late 2024. If realised, those plants could be capturing just under 0.2% of […]

White male scientists have privileges that boost their career beyond merit

White able-bodied heterosexual male scientists not only avoid the disadvantages experienced by women, minoritised racial groups and other marginalised identities, but also experience exclusive benefits associated with their status. This, according to an analysis of more than 25,000 US scientists’ survey responses, allows white men more career opportunities, professional respect and higher salaries that can’t […]

US environment agency announces new safety limits for fluorinated chemicals

The US Environmental Protection Agency (EPA) has issued stricter safety standards for four different per- and polyfluoroalkyl substances (PFAS) in drinking water, saying that these chemicals are more hazardous than previously thought. Now the agency is considering regulating these compounds as one class rather than individually. So far, the EPA has identified about 8000 different […]

Liquid metal boosts platinum catalyst’s activity 1000 times

A catalyst comprising tiny amounts of platinum dissolved in liquid gallium can be three orders of magnitude more active than solid platinum catalysts for electrochemical methanol oxidation, researchers have shown. In the quest to maximize atom economy in precious metal catalysts, the ultimate limit is often achieved by single atomic dispersion of the metal’s active […]

Light-activated cancer treatment uses tumour-targeting enzymes to cut side effects

Show Fullscreen A new two-component cancer therapy uses a modified enzyme to activate a light-sensitive prodrug compound, triggering cell death exclusively in cancerous cells irradiated with a laser. The experimental treatment has already shown promise in mouse studies. Known as photodynamic therapy, this type of treatment relies on the reaction of a photosensitive molecule with […]
