  • Educational and Entertaining!

    This podcast is perfectly bite sized. It presents chemical and historical information on various compounds and elements in an effective and entertaining manner. I particularly enjoy the multiple different narrators.

    Edit: just finished relistening to this podcast 2 years later, and it holds up just as well the second time through! I particularly enjoyed the comedic physical descriptors of the shapes of compounds.

  • Extremely informative

    One of the best podcasts out there. Such a shame they stopped producing any more episodes. Please please please bring it back. This podcast is the SOLE REASON i decided to become a doctor of chemistry.

  • Awesome

    Do you know how sometimes you go searching for podcasts, and click follow on the interesting titles so you can go back later? Sometimes you might not even pay attention to who produced it. No? I do this all the time.

    Imagine my great delight to hear Dr. Chris Smith is part of this. I will update this review when I get caught up.

Talking Points

Recent interactions between the hosts and their guests.

Inert materials & the Mary Celeste | The chemical breakdown podcast
Q: What are the practical implications for lab practice and material choices when inert components can participate in reactions?
Mason Wakley and Phillip Broadwith discuss that materials like stainless steel can abrade and release particles that catalyse reactions, so researchers should test material compatibility and consider separate utensils for different elements to avoid contamination and misinterpreted results.
Inert materials & the Mary Celeste | The chemical breakdown podcast
Q: So, Phillip, let's break down the story. What exactly is mechanochemistry for those of us who haven't heard of that field?
Phillip Broadwith explains that mechanochemistry is a solvent-free approach where the energy for reactions comes from grinding solids in a ball mill, allowing reactions to occur without bulk solvents and often enabling different, more sustainable reaction pathways.
Battery week 2026: The EV cathode race & battery-recycling | The chemical breakdown podcast
Q: What potential barriers exist for scaling these technologies?
Resource supply, especially cobalt, geopolitical risks, and the need for cost reduction; also the integration of high-performance charging and the overall system sustainability.
Battery week 2026: The EV cathode race & battery-recycling | The chemical breakdown podcast
Q: How does the aging process affect NMC versus LFP?
Aging is mainly important for NMC to ensure the right crystal structure for lithium intercalation, extending performance, while LFP requires less aging due to its inherent stability.
Battery week 2026: The EV cathode race & battery-recycling | The chemical breakdown podcast
Q: What are the key differences between the two cathode chemistries?
NMC offers higher energy density and longer range but at higher cost and resource intensity, while LFP is cheaper, generally longer lasting, but with a shorter range; regional preferences also reflect cost and supply considerations.
