Ultrafast OE Group

#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…

🚨@HopperLab is hiring! We seek a #postdoc strong in the ways of #ultrafast instrumentation. Must be willing to train Padawans. Strike down this form with all your expertise—and your journey to the Dark Side will be complete. forms.gle/5jX5pLCb2bX7H4… #chempostdoc #AcademicTwitter

Also presenting @AmerChemSociety #ACSSpring2025 this Sun, Mar 23! Join us at 4:50 pm, 33B (Convention Center) to see how @pulse_institute @SLAClab @HopperLab control and watch wavepackets wiggle in real space and time with pump-control-X-ray probe: acs.digitellinc.com/live/34/sessio…

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/wt… Well done @JunzhiYe, Navendu and team!

📰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

Now Dr Ziming Chen from @bakulingroup presenting at our joint symposium with @OxInst to celebrate @ShunWatanabe_ and their award of the Sir Martin Wood Prize! @LondonNanotech @ambercentre @EPSRC @ImpMaterials @OxfordChemistry @SandrineHeutz

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/ac… @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/art…

🚨 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/s4146…

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/s4137…

@NatureMaterials @TheNeath @DmitryMaslenni4 @_Navendu_Mondal Thank you to all co-authors, including @KovalenkoLab @vaynzof @TheRappeGroup @riken_en and others!

🚨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/s4156…

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

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!!🌟

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!

Congratulations to our freshly minted PhDs, Dr Shawn Zheng and Dr Alice Meng, who passed their vivas recently!! @CPE_Imperial @impchemistry
