A sprinting start to materials synthesis 🏎️🏁 So much for leaving materials to bake over the weekend. We captured the first moments of a solid-state reaction using in situ X-rays and they go FAST! Mere minutes to Li4Ti5O12 anode🔋 @advancedphoton pubs.acs.org/doi/10.1021/jac…

Resolving Fast Relative Kinetics in Inorganic Solid-State Synthesis

Solid-state syntheses are generally regarded as being slow, limited by transport, and, as such, are often only stopped to check the products after many hours at high temperature. Here, using a...

🐚ACC isn't just amorphous CaCO₃🫟!? Its missing CO₃²⁻—replaced by Cl⁻ & NO₃⁻🧪. And only cleans up its composition as it crystallizes✨ Read more in @J_A_C_S with imaging📽️ & Xrays🔦🩻 @StonyBrookChem and NMR🧲@iowastatechem @efrcgenesis pubs.acs.org/doi/10.1021/jac…

Non-stoichiometry Governs the Pathway from Amorphous to Crystalline Calcium Carbonate

The controlled crystallization of calcium carbonate underlies the elaborate architectures of marine corals, the design of biomimetic materials, and the global carbon cycle. Despite its ubiquity, the...

Self care tip💅from UiO66? Take it slow to fully relax. Using insitu Xrays🔦🩻 we see UiO66 shrinks when heated🔥 but only re-expands when cooled slowly🐢🧊. Cool too fast🏎️ & it gets trapped thanks to some twisted node dynamics! @SimonVornholt @J_A_C_S doi.org/10.1021/jacs.4c05313
