Chemistry in its element

This week, we are celebrating Chemistry World's Battery Week with a special battery-themed episode! We discuss the race between cathode materials for electric vehicles and a new photocatalyst capable of turning plastic waste into hydrogen and value-added chemicals, with Neil Withers and Patrick Walter.
A race between competing battery cathode materials is heating up, the winner of which will shape the future of electric vehicles. But which will come out on top?
And, we discuss a new photocatalyst that could change the way we recycle plastics and battery acid, demonstrating how waste streams could be transformed into resources. We explore what this could mean for building a truly circular economy.

This week, we discuss vanadium's potential in the medical field and the changes you can make in our lab to reduce your carbon footprint, with Jennifer Newton and Emma Pewsey.
Many are familiar with vanadium's role in metal production, but did you know that it has a history of research as a potential medicine? We explore the little-known story of vanadium's medical potential.
And, how can your lab contribute to a more sustainable world? We discuss the areas where you can make a meaningful change.

This week, we discuss how to ensure experimental instruments are truly inert and chemistry's answer to the fate of the Mary Celeste, with Phillip Broadwith and Mason Wakley.
A new study has demonstrated how unexpected results can arise from experiments using seemingly inert materials. How do we avoid the effects of these accidental reagents?
And, scientists may have found the answer behind what happened to the crew of the infamous ship the Mary Celeste. We explain how chemistry may fill the gaps.

This week, we discuss the peculiarities of water's behaviour and how science sleuths are fighting disinformation with Philip Robinson and Emma Pewsey.
A recent study from researchers at Stockholm University has found the existence of a critical point in supercooled water, which could prove the existence of two types of water. How did they do it, and what does this mean for our understanding of this fundamental substance? 
And, in the growing age of disinformation, how can we equip ourselves to discern fact from false data? We discuss the latest wave of science sleuths aiming to provide us the tools.

This week, we discuss team discuss the boundaries of the atom and breakdown the US's plan to eliminate synthetic food dyes with Jennifer Newton and Phillip Broadwith.
The atomic radius of an atom is a concept we are taught from early in our chemistry careers, but for such an important value its definition remains ambiguous. Why is there no single answer to the size of an atom?
And, US Health Secretary Robert F Kennedy Jr announced last year that the US will phase out all petroleum-based synthetic dyes in foods. But what are these chemicals, and what concerns exist around their consumption?
