We used 3D electron diffraction to elucidate the crystal structures of XePt₂F₁₀ and XePd₂F₁₀. Based on these findings, we propose structural models for the first noble-gas compound, XePtF₆. #InorgChem #3DED #Xenon #ChemSky #OpenAccess 📃 doi.org/10.1021/acs....

Crystal Structures of XeF2·2PtF4 and XeF2·2PdF4 Determined by 3D Electron Diffraction and Structural Models of XePtF6
Although the demonstration of noble-gas reactivity represents one of the most significant breakthroughs of 20th-century inorganic chemistry, the first noble-gas compound, XePtF6 (XeF2·PtF4), lacks com...

Are you interested in mechanochemistry and porous materials? Maybe solid form screening and control? Or perhaps periodic DFT? 🙋‍♀️ For all that and more, read our brand new open access paper in JACS: 🥳 (details below) pubs.acs.org/doi/full/10....

Mechanochemical Solid Form Screening of Zeolitic Imidazolate Frameworks Using Structure-Directing Liquid Additives
We demonstrate a systematic application of the mechanochemical liquid-assisted grinding (LAG) methodology to screen for forms of zinc imidazolate (ZnIm2), of fundamental importance as the simplest mem...

The second paper from our project is out in PCCP, in open access! This wonderful collaboration with our colleagues from the Institute for physics resulted in a home-made Raman system for in situ monitoring of mechanochemical ZIF syntheses 🥳 t.co/dKB9OpDgJ1

Today is #NationalTeflonDay 🍳 Teflon is a fluorochemical, a group of stable and long-lived compounds that have generated environmental and health concerns. This graphic looks at the uses of these compounds, the concerns, and possible alternatives: www.compoundchem.com/2024/12/06/p... #ChemSky 🧪
Infographic on fluorinated 'forever chemicals' and where to find them. Fluorochemicals are organic (carbon-based) compounds that contain fluorine atoms in place of hydrogen atoms. These compounds are often referred to as “per and polyfluoroalkyl substances”, or PFAS. 

The bond between carbon and fluorine atoms  are very strong and stable. Because of this, PFAS don’t break down easily and can accumulate, posing potential problems for human health and the environment.

The graphic goes on to show the structures of some common PFAS and details their uses.

Please help me get this opportunity in front of as many potential future marine biologists as possible. We have a team standing by to answer their questions but we need questions!

Today, along with 2,000 other NIH employees, I had to clear out my office 😭 It was truly the honor of my life to work with such incredibly passionate people focused on improving human health. I’ve never experienced a more positive culture where *everyone* cared about their job and serving others.

If you wish ACS to sign onto the (linked within) letter being organized by the American Psychological Association, emailing comments@acs.org with your comments plus member number is likely the best start for action. #chemsky 🧪⚗️

I’ve followed @tkingfisher.bsky.social for a while on social media and found her very funny and charming. So when I came across “A house with good bones” in a Croatian bookstore, I figured I’d give it a shot! Started this morning, couldn’t put it down, finished this evening 😅 Absolutely amazing!
An orange beach towel is on a pebble beach with clear blue sea and a blue and orange dusk sky behind it. On the towel lies a book by T Kingfisher titled a house with good bones. The cover is dark with white writing and there are red roses and some kind of masked figure on it
