The team’s latest paper is out in @jacs.acspublications.org, exploring conformational isomerism, flexibility, and postsynthetic modification in MIL-53(Sc)-fum (which we make from MIL-88A!) Big collaborative effort including help from @clairehobday.bsky.social pubs.acs.org/jacsat/artic...

Cluster Anion Substitution Tunes Flexibility and Porosity of MIL-53(Sc)-fum Conformational Isomers Isolated by Solvent-Induced MOF-to-MOF Self-Assembly

Abstract. Metal–organic frameworks (MOFs) of the type MIL-53(M)-fum, where M3+ cations are connected by fumarate (fum) linkers in the canonical MIL-53 topo

"If the scientific community fails to address the influence of AI, then authentic research and validated findings will slow down to an expensive trickle into established knowledge, and the opportunities for flawed or fabricated info to be seen as reality will grow—all while AI profiteers cash in."

AI in scientific publishing: Slower, worse, and more expensive

There’s a saying in the management world, popularized by NASA administrator Daniel Goldin in the 1990s, that the goal of technological improvements is to make products faster, better, and cheaper. Alt...

First time I've seen substitution into DCM actually wanted! Only 3 equiv CH2Cl2 will mitigate problems, as amines + CH2Cl2 make thermally unstable products: a pain & explosion risk. CH2O byproduct not great for further low-level imps. But very innovative! #chemsky pubs.acs.org/doi/10.1021/...

Reappraising Dichloromethane: Uncovering a Hidden Coupling Reagent for Activating Carboxylic Acids in Direct Amide Synthesis

Amide bonds are essential in biology and chemistry, yet their synthesis often requires expensive reagents or harsh conditions. We report that dichloromethane (CH2Cl2), a commonly used solvent, can fun...

Hey #nmrchat #chemsky: I have several users in ChemE who are running very acidic samples for reasons (I think they are functionalizing something something, I don't know, I try not to know). ANYWAYS of course the samples are not shimming well. And one user wants to run in deuterated sulfuric soon
