FeaturesNegative emissions technology needed to head off climate change
The National Academies of Sciences, Engineering, and Medicine is calling on the US government to launch a concerted effort to develop new and improved negative emissions technologies to remove and sequester CO2 directly from the air. The panel concludes that these technologies, which involve chemical processes to capture carbon dioxide from the air, are economically viable and crucial to mitigate the threat of climate change.
‘We can now say that there is a high probability that we can produce a viable way to do direct air capture at something like $100 (£77) per tonne of CO2 or less,’ says Stephen Pacala, an ecology and evolutionary biology professor at Princeton University who chaired the committee that wrote the report. ‘We would then reach the capacities that the world would need to achieve the climate goals that are embedded in the Paris agreement and elsewhere,’ he tells Chemistry World. ‘It would also provide a way to continue to use fossil fuels, but without a climate impact – you could offset those carbon emissions.’ -

ResearchBig problems with little particles?
Nanomaterials have been on the scene for more than 15 years and they are being applied in a variety of sectors including coatings, textiles, energy, security, IT, food, cosmetics and medicine. They have unique properties compared to their larger counterparts such as the ability to squeeze into spaces inaccessible to larger particles. But with the research still in its infancy, their long-term effects on human health and the environment remain poorly understood.

ResearchLawrencium experiment could shake up periodic table
Lawrencium’s position on the periodic table may now be up for debate after scientists in Japan successfully measured the first ionisation potential of the synthetic f-block element. The result may provide fuel for arguments that lawrencium and its close cousin, lutetium, should be considered part of the central d-block.
