Happy Friday! @LyssiotisLab and I had a fun time hyping up our favorite metabolite Uridine as the Metabolite of the Month in @CellCellPress! We hope you enjoy this quick read!

Better late than never, happy to help with this one !
From the cover of ACS Nano: @RRobinson_ITH and team at @CornellMSE discover three #isomerization intermediates during the amides-facilitated α-to β-phase isomerization of CdS magic size clusters. #StarkEffect @Cornell Read: https://t.co/ZAlgQr4qQC

Last week, @tomugras (@RRobinson_ITH group) from @Cornell analysed Nanocluster films at @b23_diamond, @DiamondLightSou using our MMP facility. #chirality #films #MaterialsScience

Wrapped up another successful run at @b23_diamond ! Quick pass through London too for the football and the food - thanks for the tour of UCL Chemistry @_AishaMumtaz_ 🧬🧪⚛️

(Dr.) Frank’s last day in the office ! Congrats my friend, you’ve done so great and taught the team so much. Check out our first paper together - he says it was his favorite work throughout his PhD :) https://t.co/TcedaqaioD We’ll miss you dearly !

Feels good to have the talks over with-been great to meet so many scientists whom I look up to, too !

Thanks to @JDislistening and the REACT team. And of course @jesswade for the inspiration - took a lot of elements from the chiral team over at Imperial ! And @gimmecoffee for the chiral pastries !

Summer outreach day with Cornell’s REACT( https://t.co/oNWYLfum19)! Fun with chirality and cross-polarization: R/S-carvone, helical sugar molecules, and strain-induced birefringence (“pastarimeter” not pictured!).

Can we still measure CD with CD spectrometers? Highly anisotropic nanostructures can cause problems, as artifacts appear in the circular dichroism spectrum that can’t be removed. More info in our new paper: https://t.co/GxYb6d6ORm

A fitting friend to find as I wrapped up my beamtime at @b23_diamond late last night ! Was a lot of fun, and the data is just amazing 🐚😵💫🧬

This week marks the 20 year anniversary of the unjustified, US-led invasion of Iraq. Millions of lives lost and harmed, one of the greatest crimes humanity has ever seen. Weighs heavy on the mind as Russia does the same.

I had to return this to our library this week after having it checked out >1yr. Good read. So good I scanned into a .pdf…I’ll miss the hard copy though.

Give it a read @acsnano !
Did you know that artifacts from linear parts of your sample can create imposter CD data? Turns out there is a straightforward way to extract the true-CD; we derive it and measure the true circular dichroism in CdS magic sized cluster chiral films. ACSNano

Today was a treat! We were spoiled with a visit and seminar from our collaborator @CleanUoft, predicting with ML how tiny tweaks can greatly impact material properties and phase stability
