Proud to share my latest work from the @Kempa_Group @TomKempa out in ACS nanoscience Au! We systematically control WSe2 precursor chemistry and show how the surprising crystal shapes which emerge have strongly altered optical properties.

It was an honor and a pleasure to host @brandicossairt as our first student-invited speaker this year! Turnout from @JHUChemistry was fantastic for two amazing talks about semiconductor nanocrystals and mentorship in the sciences!

[Kempa Group @Kempa_Group]

Another great effort from the TMD subgroup! Congrats to all authors!

[Thomas J. Kempa @TomKempa]

New paper from @Kempa_Group! We extend our substrate-catalyzed growth method to the synthesis of MoSe2 nanoribbons and set the stage for study of complex heterostructures ...

Congrats to all authors! @ErickSadler @TomojitC @Reynolds_DG @amb_ona

We are elated and proud of this accomplishment, Ona!

[Ona Ambrozaite, Ph.D. @amb_ona]

Sunny morning with some very happy news: excited and humbled to say that I was awarded the NSF GRFP fellowship! Huge thank you goes to the amazing mentor @TomKempa, the entire @Kempa_Group family, and so many more individuals who have been part of the journey. Yay! 🎉🥳🎉

The MOF subgroup is getting into the fall spirit with some #pumpkinspice precursor!

[Kempa Group @Kempa_Group]

Congratulations to Shreya who won a @JHU_HOUR Provost's Undergraduate Research Award! She will work with @Reynolds_DG on understanding (and controlling) the synthesis of TMD nanocrystals.

[Kempa Group @Kempa_Group]

Come join our dedicated and creative team in a vibrant research environment @JHUChemistry!

[Thomas J. Kempa @TomKempa]

Positions available! The Kempa Lab is hiring 2 postdocs for projects focused on nonlinear mechanics, single-photon emission, and energy storage in 2D crystals (atomic & molecular). Please RT.

Congratulations to @ErickSadler on an excellent Ph. D. defense!! The 3rd @Kempa_Group student to graduate, Erick developed deep chemical insights enabling us to prepare and understand the mechanism of growth of 2D materials.

All the best at LPS as a #NRC postdoc fellow!

[Thomas J. Kempa @TomKempa]

Congratulations to @Reynolds_DG of the @Kempa_Group for receiving the Ernest M. Marks Award in recognition of teaching excellence! Very well deserved Reynolds!

[Thomas J. Kempa @TomKempa]

After a busy week of exciting talks at the #MRS meeting, I'd like to thank all the presenters who contributed to the success of our Symposium on 2D Materials Beyond Graphene (NM07). Thanks to my co-organizers @Zak_AlBalushi @deep29jariwala and Ying Fang.

[Kempa Group @Kempa_Group]

Some well-earned champagne!

[Thomas J. Kempa @TomKempa]

April brings another graduation from @Kempa_Group. Congratulations to our very own @TomojitC on a brilliant Ph.D. defense covering innovative ways to tune 2D materials through chemical means!

Next step, postdoc with Jiwoong Park @UChiChemistry!

Now for some champagne:

[Thomas J. Kempa @TomKempa]

Congratulations Jamie @fjclaire on an excellent Ph. D. defense!! @Kempa_Group and @JHUChemistry are proud of you Dr. Claire. You regaled us with tales of new and responsive #MOFs and new (gas-phase) methods of making them.

[Kempa Group @Kempa_Group]

Great work be everyone, showing that vapor-liquid-solid (VLS) growth is more flexible than previously thought.

[Thomas J. Kempa @TomKempa]

First paper of 2021 just published in @ACS_ANM! We show that liquid alloys confined in nanoscale trenches can catalyze the growth of semiconductor crystals. Congrats to @Kempa_Group and our colleagues @toshiba!

[Kempa Group @Kempa_Group]

Amazing work led by @fjclaire and @MarinaSolomos published in @NatureComms! They demonstrated the promise of CVD to make single crystalline MOFs with stimuli-responsive structural and electronic switching.

Next Tuesday (11/17): Come hear about creating inclusion in the workplace in collaboration with @gqsa_jhu,
@JHU_LGBTQ and JHU PHutures. Please see your e-mail or DM for Zoom info.

[Nature Communications @NatureComms]

Prof TJ Kempa (@TomKempa) and team (@Kempa_Group @fjclaire @MarinaSolomos) use chemical vapor deposition to grow single-crystal 2D metal-organic frameworks that exhibit a reversible structural transition and large conductivity response. Read @NatureComms https://t.co/99EMDsWkpr
