#pumppushprobe strikes again! This time revealing that #ultrafast hot carrier trapping in InP #quantumdots hampers lasing despite high PLQY. A 9-institution collab spanning femto-to-microsecond timescales & single-QD to ensemble measurements. @NatureComms doi.org/10.1038/s41467-025-6…

Reading Frankenstein ~30yrs ago sparked my love for science. That's why this Halloween, I'm excited to share my new role as an Asst. Prof. @UCFChemistry! Coming to life Jan '25, @HopperLab will create ultrafast control tools for materials & device (MAD) science #NewPI #FloridaMan

Fabulous to see our paper selected by the editor of @NatureComms for their Editors’ Highlights page! nature.com/collections/wtpqp… Well done @JunzhiYe, Navendu and team!
Thrilled to share our latest work on defect tolerance for hot carriers in halide #perovskite #nanocrystals! rdcu.be/dT4ZK Great work from @JunzhiYe and Navendu Mondal, and collab with @bakulingroup @Polavarapu_Lab and @RaoGroupCAM
📰Out now in @NatureComms rdcu.be/dT448: Hot carriers follow the same rules for perovskite defect tolerance as band-edge carriers, with a little 'push' from @_Navendu_Mondal @ben_carwithen. Great colab with
@JunzhiYe @RobertHoye4 @RaoGroupCAM @StranksLab @Polavarapu_Lab
This week we welcomed back former student Dr Ben Carwithen, discussing his work on singlet fission solar cells at UNSW Sydney! @ben_carwithen

Another step closer to understanding the photophysics of chiral 2D perovskites! 💠 Such a pleasure to work with @scalon_lucas, @AnaFlaviaNogue5, @bakulingroup and theory friends! 🤓 Please check it out #OpenAccess at pubs.acs.org/doi/10.1021/acs… @ChemMater @ct_qmat

Another great collaboration with @GroupHeeney on NIR organic photodetectors. Here, we show a selenophene based NFA with detection >800 nm. Congratulations @Zhuoran_Qiao for your first author paper! @impchemistry @TDAnthopoulos @bakulingroup @CPE_Imperial pubs.rsc.org/en/content/arti…
🚨 New paper out now in @NatureComms - Carrier trapping dynamics in perovskite solar cells using pump-push-photocurrent spectroscopy! @_Jiaxin_Pan @GroupHaque @WeidongXu7 @Nicogaspa @alicemeng2333 @DavideNodari97 nature.com/articles/s41467-0…

Here, vibrational control of FAPbBr3 perovskite solar cells is demonstrated, where the fast dynamic coupling between cations and inorganic sublattice suppress non-radiative recombinations in perovskites, leading to reduced voltage losses. @bakulingroup go.nature.com/46BREUF
📰News (& Views) just in... @_Navendu_Mondal @ben_carwithen report on a recently published paper in @LightSciAppl by @Dai_Linjie @JunzhiYe @DeptofPhysics: Alloying metal cations in perovskite nanocrystals is a new route to controlling hot carrier cooling nature.com/articles/s41377-0…
🚨NEW PAPER out now in @NatureMaterials - by vibrationally promoted electronic resonance (VIPER🐍) spectroscopy, we reveal the coupling between the organic cation and the inorganic cage in hybrid perovskites! @TheNeath @DmitryMaslenni4 @_Navendu_Mondal nature.com/articles/s41563-0…

Happy to share I passed my PhD viva last week, and it appears I was just as excited by the balloons afterwards! Thank you to Artem and everyone in the @bakulingroup for a wonderful four years @impchemistry @CPE_Imperial

Thrilled to finally share that I got my PhD!! Wouldn't be possible without the mentorship and support from @bakulingroup @Nicogaspa and the wonderful community @impchemistry. Huge thanks to @jesswade and Frédéric Laquai, who did my viva exam! Onwards to further science adventures
Congratulations to our freshly minted PhDs, Dr Shawn Zheng and Dr Alice Meng, who passed their vivas recently!! @CPE_Imperial @impchemistry
Alice's (@alicemeng2333) research focused on trapped carrier dynamics in water oxidation photoanodes, ⚡️🫧 co-supervised by
@durrant_group @CoatingsSolar. Thank you to examiners Dr Alex Rettie (UCL) @rettie_alex and Dr Nicola Gasparini @Nicogaspa!
Alice now joins @titiricigroup @Petit_Group @Interfacial_EC as a postdoc working on high-throughput screening of electrocatalysts for green H2 production! First lasers, now robots - seems like the start of a good sci-fi movie... Good luck!!🌟
