Photochemistry enables safer method for reprocessing plutonium and uranium mixtures

Photochemistry can be used to separate plutonium and uranium, new research shows. By showing that photochemistry can replace harsh redox agents during actinide separations, the work could benefit nuclear processing facilities and environmental remediation efforts. The redox chemistry of the actinides plays a vital role in the chemistry of separating them. The near overlapping energies […]

Beinecke Library Redux: From Bad to Worse!

On Monday I wrote a quick blogpost on the not insubstantial errors in the description of one of Galileo’s lunar washes posted on the Beinecke Library blog. I was somewhat pleasantly surprised when with a day the description had been heavily edited, romovi9ng all the sections that I had criticised even if no acknowledgement was […]

Nobel prize rewards click chemistry and bioorthogonal reactions

This year’s chemistry Nobel prize is shared equally between the click chemistry pioneers Barry Sharpless and Morten Meldal, and Carolyn Bertozzi, who shaped the field of bioorthogonal chemistry. For Sharpless, this is his second chemistry Nobel prize – he’s only the second person after Frederick Sanger to receive two chemistry prizes. ‘I’m absolutely stunned, I’m […]

Not with a bang but a whimper

Ethan Siegel is an astrophysicist, but he is better known as a highly successful science populariser, who even has his own Wikipedia page.  He first rose to fame as the author of the blog Starts With a Bang, which he launched in 2008. He expanded his brand, with the publication of popular books on physics. He expanded still […]

Setting the standard for calculating indirect emissions

A group of chemical companies has developed guidance to help industry calculate the cradle-to-gate emissions of the chemical products it purchases. Together for Sustainability – which includes global players – said the ‘first of its kind’ guideline would harmonise product carbon footprint (PCF) calculation approaches across the industry, to provide quality footprint data that are […]
