It’s WATOC 2025 time. See a bunch of you in Oslo in a few days time.

[David J. D. Wilson @DavidJDWilson]

Beautiful crystal structures of the first characterized Be-N and Be-O triple bonds published in @J_A_C_S. Great work from @Jones_Research - awesome to collaborate on this one!

[CCDC Cambridge @ccdc_cambridge]

The synthesis and characterization of two-coordinate beryllium complexes with unprecedented Be–N and Be–O triple bonds are reported in @J_A_C_S.

CSD Entry WUYMIQ demonstrates the first s-block metal–oxygen multiple bond.

🚨New paper out now in JACS! First isolated/characterized Be-O and Be-N triple bonds from a combined experimental and theoretical study. Fantastic collaboration with Cameron Jones @Jones_Research and Christoph Helling. https://t.co/teUMMj1fv8

@ambiigames @TXpatriotpete @22liv22 @sjs856 No problem. I’ve taken an interest in fluoridation as it’s an interesting science question. Sadly, opinions (often based on misunderstanding) have heavily distorted discussions. I take an open mind to this issue.

[David J. D. Wilson @DavidJDWilson]

@TXpatriotpete @22liv22 @sjs856 No point to this conversation. You are not prepared to consider reliable data and evidence.

[David J. D. Wilson @DavidJDWilson]

@TXpatriotpete @22liv22 @sjs856 I did some more reading and recommend this. It is a review from the Australian NHMRC org. The studies (cited) that link fluoride to lower IQ did not consider confounding factors and are thus not considered reliable. See info paper, p51. https://t.co/FilOMBr613

[David J. D. Wilson @DavidJDWilson]

@TXpatriotpete @22liv22 @sjs856 That is not my area of expertise. I am a chemist. But from what I have read from studies, I am doubtful that it has any impact on cognitive development of children.

@CheweyLife @sjs856 Please learn some chemistry and you will se thru this common misconception. These compounds dissolve in water to produce harmless species at those concentrations. Fluoride is the species - a salt of fluorine. It is chemically irrelevant about the origin - all fluoride is same

[David J. D. Wilson @DavidJDWilson]

@MaximZavet @smith_jsbe8786 @sjs856 That is chemically irrelevant. H2O is a product of chemical reactions. It is exactly the same as H2O from any other source. The molecule/chemical are all exactly the same. Same for fluoride.

[David J. D. Wilson @DavidJDWilson]

@TalonOrdo @sjs856 Think of sodium. As a salt with sodium chloride (table salt) it simply dissolved in water. As sodium metal it reacts explosively with water. Same element in a different form. The chemical makeup is very important.

[David J. D. Wilson @DavidJDWilson]

@TalonOrdo @sjs856 Please learn some chemistry. The active ingredient in Prozac is fluoxetine, with a CF3 group. It contains organic F (C-F bonds). Fluoride is completely different. Same element but in a very different form.

[David J. D. Wilson @DavidJDWilson]

@Shelleybe3 @sjs856 Please learn some chemistry - you have repeated a common misunderstanding. The compound that is added dissolves is water to give fluoride (and hydrogen ions and salicylic acid) - all harmless for human consumption at those concentrations. Fluoride is fluoride.

[David J. D. Wilson @DavidJDWilson]

@22liv22 @sjs856 Please learn some chemistry. Your analysis is mistaken. The compound dissolves is water to make fluoride ions, hydrogen ions, and salicylic acid. All are harmless for human consumption at the specified concentrations. Where the chemical comes from is irrelevant.

[David J. D. Wilson @DavidJDWilson]

@ghett_smart @DuttonChemistry @beneltham I do exactly that too. You have to show how and why it is the case. But I'm convinced that only 10% of the class follow it.

[David J. D. Wilson @DavidJDWilson]

@ghett_smart @DuttonChemistry @beneltham Yep. I’ve learnt to ask basic fundamental questions at 3rd year. Things we take for granted aren’t always understood by students. Every year I have students who can’t recognise a p orbital while I’m explaining QM. And basic algebra…

@AndrewPerpetua Where is the "All of the above" option 😀

[David J. D. Wilson @DavidJDWilson]

🚨new paper online: Magnetizabilities of fluorinated molecules from DFT and Benchmark Coupled-Cluster Calculations with @terri_ft and Pete Taylor for Trygve Helgaker special issue in @JPhysChem https://t.co/0Pym8Zs7IY
