An informal news log of notable events and accomplishments in the WilsonLab

  • 2021-03-05 – The WilsonLab is excited to host Prof. Phil Castellano for a remote colloquium, who told a story-in-many-parts, starting with a PI spotting the significance of some interestingly blue light, and now spans applications in 3D gel-printing, a new (magical!) Zr-based sensitizer for triplet-fusion upconversion, with some of the the very prettiest photos along the way.
  • 2021-03-03 – The lab gears up for the UofT Chemistry Department Graduate Student Weekend. TMEDA-man will be released into the wild! We may be remote, and lobster-less, but our enthusiasm is at a healthy simmer! 🚫🦞🚫
  • 2021-03-02 – Congrats to Kelly for giving a strong 2nd-year PChem seminar on ‘Exciton Auto-Ionization in PbS Nanocrystal Solar Sensitizers.’ More to come :-)
  • 2020-12-01 – Christian gives a triple-threat PChem seminar telling the tale of his research ‘Towards diffusionless triplet-fusion upconversion in solution.’
  • 2020-11-11 – Due to a coincidental overlap of some mandatory in-person laser safety training and ‘shift change’, for 15 minutes the entire WilsonLab is on campus at once for the first time since March. And it was (kind of) sunny outside! Seized the chance for a physically-distant photo op (thank you Antoine!). Research continues (stay tuned for more stories!), but year 5 of the WilsonLab will be unlike any other!

  • 2020-09-25 – The WilsonLab sends its thanks to Nick Uhas for giving his permission to Mark to show his youtube video in CHM135. Because few things demonstrate the power of a catalyst than the ‘Elephant Toothpaste’ reaction… run on the ton scale!!
  • 2020-09-08 – After an extraordinary summer for us all, we were thrilled to welcome new doctoral students Francisco, from the Majewski Lab at Concordia, and Maxine from the Dasog Lab at Dalhousie.
    Canadian Nanoscience: Let our powers combine!
  • 2020-09-07 – Philippe is at it again, with a new paper in J. Mater. Chem. C. showing that glycol ethers themselves can shape the nucleation dynamics of PbS nanocrystals by suppressing the lead-rich cluster intermediate. This effect correlates with multidentate co-ordination to Pb(oleate)_2, corroborated by DFT calculations from our collaborators in Prof. Voznyy’s Clean Energy group at UofT Scarborough.

    In the colloidal synthesis of PbS quantum dots, added glycol ethers variably suppress the formation of metastable cluster intermediates. This achieves control of nanocrystal size in reactions run to completion.

    Check out WilsonLab ResearchTalks to listen to Phil tell his own story!

  • 2020-08-12 – Incoming Wilsonlabber Francisco featured in a Concordia University Press Release describing his M.Sc. work to functionalize ZnO nanowires with carbon nanodots to boost their photocatalytic abilities.
  • 2020-08-26 – Mark gives an invited talk (Remotely) at the 2020 SPIE Optics + Photonics meeting.
  • 2020-08-19 – Mark & Minhal give talks at the (on-line) 2020 Fall Meeting of the American Chemical Society. Curious? Check out WilsonLab ResearchTalks on Youtube to hear both telling their stories!
  • 2020-07-27 – Sometimes science surprises. Read in JPC Letters how Minhal showed that sub-bandgap optical modulation suppresses long-duration ON events in CdSe|ZnS quantum dots—in a timescale-free manner! #FirstOrderKineticsAreForTextbooks Or, better still, listen to him tell the story himself in one of the first WilsonLab ResearchTalks

    We develop an all-optical modulation scheme and demonstrate that sub-bandgap light tuned to the stimulated emission transition perturbs the blinking statistics of individual CdSe/ZnS core/shell QDs. Resonant optical modulation progressively suppresses long-duration ON events, quantified by a power-law slope that is more negative on average (Δα_ON = 0.46 ± 0.09), while OFF distributions and truncation times are unaffected.

  • 2020-07-10 – To celebrate papers, comprehensives, courses, and a safe return to physically-distant-labwork-on-rotation, the WilsonLab manages a socially-distant social via In Reasons that Mark went into science, Episode 4306, I give you… ‘Schlenk Line’
  • 2020-05-01 – Thrilled to share Philippe’s discovery that small, lead-rich, pre-nucleation clusters complicate the growth kinetics of small PbS nanocrystals, but can be controlled with amine additives to yield unprecedentedly narrow ensemble linewidths! Though the paper, in Chemistry of Materials, might be our third paper chronologically, it’s the first story in our hearts! A creative efforts from all authors, and there will be more to see here soon!Graphs showing that amine additives accelerate PbS nanocrystal nucleation by suppressing a cluster intermediate, leading to narrower ensemble linewidths for small (diameter less than 4nm) nanocrystals
  • 2020-03-19 – After four long days of hustle, the Wilson lab is set for shut-down as part of the University’s response to the COVID pandemic. It’s certainly a disruption, but there are times when it’s more important to do one’s bit. Farewell, freshly-regenerated gloveboxes (<200ppb O2/H20!), we’ll be watching you (…as we furiously work on manuscripts!) All squared away for shut-down in the synthesis/fabrication room WilsonLab
  • 2020-03-07 – WilsonLabbers participate in an action-packed Graduate Student Recruitment Weekend. Kelly’s poster game proved very strong, and keyed many conversations with the strong class of prospective PChemists. Looking forward to new faces in the fall!
  • 2020-02-12 – An unseasonably warm day in February lets us take a new group picture outside! Knox College across-the-road serving as a lovely backdrop. At this point we choose to emphasize that the University of Toronto does not ‘own’ Knox College… for reasons… WilsonLabbers, February 2020 edition
  • 2020-01-24 – Prof. Wilson returns to Queen’s University to give a departmental colloquium in the physics department. A day filled with great interactions with grad students, and hearing of exciting directions in nanoscale light-matter interactions from faculty—both familiar faces and fellow early-career researchers! Wilson lab student Philippe Green out for dinner with the Yanai group in Fukuoka
  • 2020-01-08 – Philippe visits the Yanai group at Kyushu University in Fukuoka to present his latest insights into the mechanism of nucleation and growth of PbS nanocrystals—key materials for triplet-fusion upconversion. (Not just our favourite topic, but one where Nobuhiro’s team continues to make groundbreaking discoveries!) Thanks to all the Yanai group members for great interactions and kind hospitality.
  • 2020-01-01 – The WilsonLab rings in the new year by welcoming new graduate student Kelly-Marie Yokuda! Kelly joins us from WWU with an interest (and track-record!) in using spectroscopy to explore how molecular structure influences excited-state dynamics in in molecules and nanostructured materials.

  • 2017-03-03 – The Wilsonlab participates in the Chemistry Department’s Graduate Student Weekend, where we welcome students who’ve been made an offer to begin post-graduate studies here in the fall. Prof. Wilson enjoyed many interesting discussions about research and graduate life, both formally in one-on-one meetings, and informally at the departmental dinner. Particular thanks to Christian for quarterbacking the creation of a new poster summarizing our group’s ongoing research, and to Karen and Minhal for helping him present our work to prospective graduate students at the weekend session.
Much crate. Very disassemble.
  • 2018-02-23 – Wilsonlabbers finish the installation and commissioning of our new thermal deposition system, proudly manufactured by Angstrom Engineering in Kitchener, ON, and bought with financial support from CFI, ORF, and the University of Toronto.

We’ll now be able to use physical vapour deposition to precisely fabricate the thin (few-nanometer!) films of conjugated organic molecules that we’ll study spectroscopically, and use to build our excitonic upconversion devices. Our suite of synthesis and fabrication capabilities is complete! (For now :-) The sushi burritos were also delicious…
