  • Lots of lead in the water? Maybe manganese is to blame

    Manganese is not a particularly toxic mineral. In fact, people need a little in their diets to remain healthy. Research at Washington University in St. Louis has shown however, that in conjunction with certain other chemicals, naturally occurring manganese can lead to big changes in the water in lea more

  • Perovskites - materials of the future in optical communication

    Researchers at the universities in Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future rapid optical communication", says Feng Gao, researcher at Linköping Univers more

  • A smartphone system to test for lead in water

    The discovery of lead in Flint, Michigan's drinking water drew renewed attention to the health risks posed by the metal. Now researchers at the University of Houston have created an inexpensive system using a smartphone and a lens made with an inkjet printer that can detect lead in tap water at leve more

From Liquid To Gel: A New Test for Lead in Paint

A new molecular gel recipe developed at the University of Michigan by Anne McNeil, Arthur F Thurnau Professor of Macromolecular Science, and is at the core of a prototype for a more accurate lead paint test.The new test is more clear and accurate than its counterparts. It consists of a vial that ... more

Chemistry and the Flint Water Crisis

Virginia Tech researchers helped prove that lead levels were dangerously high in Flint’s tap water, even when government officials denied the problem. We visited the researchers to see how they're using standard analytical chemistry to try and make water safer. more

Group 4 Elements

This latest infographic focuses on the Group 4 (Group 14 in IUPAC nomenclature) elements. One extra fact to add for the curious: although tin has the greatest number of stable isotopes, Xenon trumps it comprehensively if unstable isotopes are also included in the count, with well over 30 possible is more

Lead Iodide & ‘Golden Rain’

Kicking off an occasional new series of graphics with today’s post, which’ll be looking at common chemical reactions encountered in schools. Today kicks off with one of my favourite reactions, the ‘Golden Rain’ demonstration, which involves the synthesis and recrystallisation of lead (II) iodide, an more

The Chemistry of Petrol & The Tetraethyl Lead Story

18th May marks the date of birth of Thomas Midgley, who made significant contributions to something many of us make use of on a regular basis: petrol. Midgley was the research assistant to Charles Kettering, and the duo were responsible for the addition of the compound tetraethyl lead to petrol, an more
