Hey #chemtwitter, does anyone know where to find a good model/file for 3D printing a nanocrystal? Would love to print one for my desk!

I've been a longtime user of Origin for plotting my data, but I'm wondering what #chemtwitter likes to use? MATLAB? Igor? Python? R?

[Sam Harvey @NanoScienceSam]

@IUBChemistry Can’t think of a more deserving person! Over six years since I graduated IU and you are still a remarkable mentor. Congrats to you Sara!

A new student who works with nanopipettes has really bad eyesight and was having trouble filling the small devices with fluids. My other student 3D printed a funnel as a X’mas present to help her 👏😭 Innovation at its finest with kindness, I’m so proud.

@Zoha_H_Syed @WOMBO Honestly I would love a print of that

[Sam Harvey @NanoScienceSam]

Totally forgot to mention that this was done in collaboration with the amazing Korgel group (@brian_korgel @KorgelTweets) who synthesized the nanocrystals!

[Sam Harvey @NanoScienceSam]

Good morning twitter! I'm excited to share my newest paper from @NUChemistry in @acsnano about how synthesizing CuInSe2 nanocrystals with different ligands drastically affects their composition and photophysics! https://t.co/arBip30JeH

[Sam Harvey @NanoScienceSam]

In this Perspective we look at some of the history of SCRPs, from photosynthetic bacteria and CIDNP/CIDEP to their use as molecular qubits. Introduction to some of the theory, quantum teleportation, SCRPs in DNA, and much more! (2/2)

[Sam Harvey @NanoScienceSam]

Hey everyone, Prof. Mike Wasielewski and I's JACS Perspective just came out! If you want to learn about photogenerated spin-correlated radical pairs (SCRPs) then look no further. @J_A_C_S @CMQTnu (1/2)

Hey twitter! I'm defending my Ph.D. in Chemistry this week! 🤯😎👩‍🔬(Thursday at 1 pm CT to be exact). I don't know as many of you on here, but if anyone is interested in attending virtually, message me and I'll send you a zoom link.

[Sam Harvey @NanoScienceSam]

Wow! Walking up to so many responses is amazing! These ligands were not native during synthesis, but were exchanged afterwards. The NC is fairly large due to the shell (~7.7 nm diameter). 90 eq. of ligand was added though so I expect a fair amount on the surface.

[Sam Harvey @NanoScienceSam]

Okay nanocrystal community, I have a question/debate. Do you think this ligand would be bent over (closer to the surface) or forced more upright? The QDs are CdSe/CdS. This ligand and QD were used previously: https://t.co/WgSXvfHJ76 but I'm using them again. Excuse my ugly pic.

[Sam Harvey @NanoScienceSam]

Hey #chemtwitter, how do you stay motivated when you are nearing the end of a paper and are getting tired of editing your own work again and again?

[Sam Harvey @NanoScienceSam]

We as a nanocrystal community really need to clarify whether we mean 'diameter' or 'radius' when we are talking about the size of a nanocrystal or labeling a figure. I am not going to remeasure your TEM images.😂

[Sam Harvey @NanoScienceSam]

Another shameless promotion since Laura isn't on Twitter, this time focused on research from the Wasielewski group @NUChemistry in @JPhysChem. This work focused on the effects that having two identical acceptors has on charge and spin dynamics. https://t.co/8SxWe563eQ

[Sam Harvey @NanoScienceSam]

A bit late, but I am excited to share two papers I'm on from the Schaller group that use time-resolved XRD to study thermal properties of nanocrystals. https://t.co/dSzxJeBpX2
https://t.co/4SbvvbWf5e @nanobrumberg is first author and gave a lovely description of both articles!

[Sam Harvey @NanoScienceSam]

I’m very excited to be presenting in this series! I’ve really enjoyed getting to see all the exciting new research on nanocrystals!

[News in Nanocrystals Seminar @NiNC_Seminar]

Join us this week for an exciting seminar by Aniket Mule (@AniketMule93), Samantha Harvey (@NUChemistry), and Dr. Laxmi Kishore Chiluka (@Sargent_Group).

The Zoom webinar will open at 8AM PDT/11AM EST/5PM CET on Wednesday, November 11th.

The worst part is, I want to make it 50/50. I'm a woman in science and I want to boost other women. So I'll keep looking, I'm determined. I know how important representation is. I'm reminded of when I went to MRS in 2019 and was often saddened by the lack of women at the talks.

[Sam Harvey @NanoScienceSam]

A short sad tale:
Oh I see that @nanoGe_Conf is calling for new symposia, I should make one!
They say that the percentage of female speakers should be at least 20%, that shouldn't be hard
Nine speakers added to the list and I haven't found one woman scientist to add
Unacceptable
