📢Proud to share our journey in #crystallography #education over past 15 years, spanning #K12 initiatives, #undergraduate #graduate education & groundbreaking #research #methodologies @BetleyGroup @HarvardCCB doi.org/10.1107/S16005… 🌟@JApplCryst @IUCr @ACAxtal #STEM #Innovation

📢Excited to share how we’re making #crystallography @HarvardCCB accessible to #undergrads & #K12 helping inspire the next generation! #NEACT2025 bit.ly/NEACT2025 😀😀#ScienceEducation #STEMTeachers #StructuralScience #education #ProfessionalDevelopment #TeacherPD

A student asked, "Are the metals in the Fe₂Ni₂O₄ core correctly assigned, based on the deposited #SCXRD data? " 🧐🧐doi.org/10.5517/ccdc.c… @ccdc_cambridge @J_A_C_S @IUCr #crystallography #education

Preparing a presentation for #ACA2025 "Engaging Students with Crystallography" session to share our #Insights& #BestPractices for chemistry #undergraduate& #graduate @HarvardCCB 🥳doi.org/10.1021/acs.jc… @ACSPublications @ACAxtal @IUCr #crystallography #education #Twin #disorder

Making small-molecule #crystallography accessible through experiential learning supports deeper integration into #chemistry education @HarvardCCB, featured in "Advances in #StructuralScience"🥳🥳doi.org/10.1063/4.0000… #K12 #outreach #undergrad #education #graduate #research
"If students aren’t reading, it might ... be a sign that we haven’t yet helped them care ... Invite them to engage on their own terms—with #curiosity, with #creativity, and with a sense of #ownership over their learning." 😀😀hbsp.harvard.edu/inspiring-mind… #education
Typo or misconception?🤔🤔 "space group Cc ... a ≠ b ≠ c, α = β = 90°, and γ ≠ 90°" and "the measured space groups are ... P4212 (#90, #chiral)" doi.org/10.1021/acs.jc… #crystallography #education
A student is asking a good question: "Has the #isolated carbon(I) species featuring a #CarboneCationRadical truly been "#unambiguously established by #SingleCrystal #XrayDiffraction", given that the #EPR was done in THF?" 🤔🤔nature.com/articles/s4416… #crystallography #education

An easy walkthrough with a simplified process 😊🔍 youtube.com/watch?v=Q5rrf6… @bruker #crystallography #education
The #DisplacementParameters are mostly considered a convenient way to lower the refinement statistics—they're 🔑 to finding #accurate atomic positions😀😀 doi.org/10.1107/S20522… @IUCr #crystallography #education
In his article “At the movies,” Kahr offers a fascinating reflection on science, education, and inclusion—then and now. iucr.org/news/newslette… #WomenInSTEM #IUCrNewsletter #ScienceHistory
The sixth video of the “Women in Crystallography” series, supported by the @RoySocChem and @ECA_social can be watched at youtube.com/watch?v=RsuPip…. The speaker is Natalia Alvarez, Facultad de Química, Universidad de la República @Udelaruy.
While tracking down an unusual #linear H–N=C structure, a student @HarvardCCB spotted a case where O was misassigned as N 😱🧠🔬 doi.org/10.1016/j.saa.… #crystallography #education

Just about anything in a #PowderDiffractometer can give surprising insights—and sometimes new #science! 🎯🧪#EverythingReallyIsASample!🥳🥳doi.org/10.1063/4.0000… @IUCr #crystallography #education #K12 #outreach
A good read: "popular SHELXL-like #WeightingScheme leads to #bias in residuals when the standard #uncertainty values of the observed intensities are underestimated, which appears to be the case very frequently" 😀doi.org/10.1107/S16005… @JApplCryst #crystallography #education
Congrats to Faith, Jason, Jinyoung, Hailey & Malia at Mason group @HarvardCCB! 😀😀 doi.org/10.1021/jacs.5… @J_A_C_S #crystallography
Using alternative methods/solvents to avoid DCM benefits the institution, student/staff health, and the environment 👍👍 Plus, it helps with structure refinement 😉😉 pubs.acs.org/doi/10.1021/ac… @IUCr #crystallography #disorder #education
Congrats to Nick @BetleyGroup @HarvardCCB! 😀😀This work shows how a terminal ylide ligand transforms into bridging methylidyne and carbide species 👏🧪doi.org/10.1021/jacs.5… @J_A_C_S #crystallography
College students aren’t reading — at least not like they used to. What’s going on? And how are professors responding? Watch our explainer. chroni.cl/44W4rUH
This week's reading suggestion: J. Chem. Educ. 2021, 98, 3180−3188. doi.org/10.1021/acs.jc… #Crystallography Have a nice week!
📢How #photocrystallography can help your research: "Merging cryogenic #photochemistry with #SingleCrystal reaction environments provides a #unique opportunity for molecular synthesis of reactive species." 🥳#crystallography #education
Let's take a closer look at synthetic tractability using in crystallo photochemistry in our latest paper, now out in ACS Cent. Sci. (@ACSPublications). Nice job Aishanee! pubs.acs.org/doi/10.1021/ac…
