Surging #greenhouse gas #methane recorded in 2020 and 2021 despite global pandemic. We report @NatureComms methane-climate feedback sensitivity 4x > than #IPCC suggest, taking into account lags between +ve and -ve feedbacks. @NTUsg @ScienceNTU @NTU_ASE https://t.co/mAqa20983v

Down to #Earth: Where has the Earth’s missing #lead gone? That’s an age-old mystery that has stumped geoscientists. But new research led by #NTUsg may have finally provided new insights.

By exploring how lead behaves under the crushing pressures of Earth’s interior, they found that the solution to one of our planet’s oldest chemical secrets could in fact be hiding beneath our feet in the planet’s mantle layer.

The researchers used computer simulations to show that a compound called lead sulphide becomes extraordinarily stable under extreme pressures, which are conditions that can be found deep in the Earth’s mantle. The finding suggests that hidden reservoirs of ancient lead could have formed early in Earth’s history, and then remained deep in the mantle. There are also cosmic implications as the study changes our understanding of the chemistry of planets. https://t.co/c9dJwcYZc8

Our latest work shows how calcium-based CO₂ sorbents degrade over time - crucial for scaling up carbon capture tech.
We identified the sintering mechanisms limiting sorbent lifetime in calcium looping systems, paving the way for more durable materials.

@OEAMBRCH @ANdaihera “Bad luck”? I’d prefer to fly on a plane that has a track record of strong safety compliance than trust to luck. Maybe trusting to luck is what has led to Boeing being in this position?

@MineralCup Yes please

@OdedRechavi Of course

Interested in doing a PhD in volcanic petrology @ntu_ase and @EOS_SG ? 🌋 We have an exciting project looking into timescales and storage conditions prior to the 1815 Tambora eruption. For more info contact [email protected] or visit https://t.co/UWb5UdZ4IF
