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. 🔗 ccdc-info.com/4iYfbVX #FeaturedStructureFriday

🚨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. pubs.acs.org/doi/10.1021/ja…

@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.
English

@DavidJDWilson @TXpatriotpete @22liv22 @sjs856 My bad I saw the data analysis and other parts and assumed it was a study. I completely missed the fact it was a petition.
English

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

@DavidJDWilson @22liv22 @sjs856 Unfortunately you have misunderstood. Your claim that fluoride additives to water supplies “is harmless” is retarded based on extensive, peer-reviewed studies. Quit drinking the water, bruh. It’s killing your IQ!
English

@ambiigames @TXpatriotpete @22liv22 @sjs856 High (or any) levels of arsenic are not good. High levels of fluoride (above 2 mg/L) are not recommended. The question from that petition (not a research study) is about purity of the chemicals. Higher purity is better, but more expensive. Water should be regulated and tested.
English

@DavidJDWilson @TXpatriotpete @22liv22 @sjs856 Just curious thoughts on this research study? epa.gov/sites/default/…
English

@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. nhmrc.gov.au/about-us/publi…
English

@DavidJDWilson @22liv22 @sjs856 Your appeal to authority (“I am a chemist!!!!”) followed by admitted ignorance of numerous peer-reviewed studies showing a decrease in IQ among children who drink fluoridated water is exactly why people don’t trust **The Science**.
English

@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
English

@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.
English

@smith_jsbe8786 @sjs856 True but the point is that it’s a lab made chemical.
English

@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.
English

@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.
English

@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.
English

You are either not bright enough to know the truth or you are lying. Calcium fluoride is the natural occurring mineral in soil and food. Calcium fluoride is not what is added to drinking water. By-products of the fertilizer industry that are labeled as fluoride but are actually called Sodium fluorosilicate and fluorosilicic acid are what is added to drinking water. It is very poisonous and it is not the natural occurring fluoride mineral and it is not even the synthetic(still harmful) sodium fluoride. Stop talking about things you don’t know about.
English

@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.
English

@DavidJDWilson @DuttonChemistry @beneltham Not that I didn't do a visual version first, but it didn't even occur to me that you wouldn't do the maths alongside it. Like, don't take my word for it just take the square mod!
English

@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…
English

@DuttonChemistry @beneltham Agree on both. I had a third year student ask me how I turned A-B=0 into A=B, after my first lecture. Props to them for putting their ego aside, but it was a hell of a moment.
English

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