Material made of carbon and nitrogen is nearly as hard as diamond
This carbon nitride is almost as hard as diamond Dominique Laniel et al. An elusive material that scientists have wanted to make for decades has finally been synthesised under tremendous heat and pressure – and it is nearly as hard as diamond. It could potentially be used in cutting tools, sensors and even as an…
Can Rock Dust Soak Up Carbon Emissions? A Giant Experiment Is Set to Find Out
Mary Yap has spent the last year and a half trying to get farmers to fall in love with basalt. The volcanic rock is chock full of nutrients, captured as its crystal structure forms from cooling magma, and can make soil less acidic. In that way it’s like limestone, which farmers often use to improve…
Carbon dioxide emissions from fossil fuels hit another all-time high
CO2 emissions from fossil fuels are still rising globally Jose A. Bernat Bacete/Getty Images This year’s total carbon dioxide emissions from fossil fuels are projected to reach 36.8 billion tonnes by the end of 2023 – another all-time high. The finding, from the annual Global Carbon Budget report, adds to the long list of alarming…
We can trigger positive tipping points to cut carbon emissions faster
The rapid growth of solar energy in recent years can be seen as a positive tipping point Henry Do/Solent News/Shutterstock There are tipping points in technological, economic, political and social systems that could lead to carbon emissions falling faster if triggered, according to a major report. The authors of the Global Tipping Points Report are…
