Congatulations Yuta and Wataru for getting the Poster Prize at The 46th Workshop on Photochemistry for Young Researchers! We'd appreciate the organizers for their great efforts.
Our previous group member Tomoyuki has returned to Japan after a short postdoc stay at the Wasielewski lab. Thanks for the Northwestern wine glass!
Tomoyuki has just been appointed as an Assistant Professor at Kyushu University. Huge congratulations, best of luck in your future endeavors!

Many thanks Christian Doonan for visiting us and giving an inspiring seminar! We enjoyed delicious sushi too much so totally forgot to take a photo😅 Instead here’s a photo with his favorite Taiyaki. See you soon in Kyoto next week!
It was our great pleasure to host Prof. Shie-Ming Peng from NUS today. We appreciate the beautiful coordination chemistry of “Peng Dragon” and the interesting stories related to Prof. Nozoe.
A bit late to post about our new work; we carried out dye–quencher pair screening and found new efficient photo-CIDNP pairs.
Many thanks J. Chem. Phys for choosing this as Editor's pick!
Congrats Toshiteru, Takuya, and all!

Metal Ion Dynamic Nuclear Polarization in Mn(II)-Doped CdS Nanocrystals: Atomic-Scale Investigation of the Dopant and Its Host
Development of functional nanocrystals requires precise control over their composition and structure. Particularly, surface composition, defects, and doping play a central role in our ability to develop functional nanomaterials. As such, there is great interest in capturing these properties. Solid-state NMR spectroscopy is a powerful tool for probing structural and compositional features at the atomic scale, in particular, when it is coupled with the high sensitivity gained by dynamic nuclear polarization (DNP). DNP enhances NMR sensitivity by transferring high electron spin polarization to the surrounding nuclear spins. This dramatically improves the signal intensity, making it a valuable tool for detecting subtle structural features. Utilizing metal ion dopants as polarization agents for DNP has been shown to be an excellent approach to increasing ssNMR sensitivity in the bulk of inorganic solids. Here, we demonstrate the implementation of this approach to nanocrystals, focusing on Mn(II)-doped CdS, where homogeneous doping is known to be challenging while being critical for the DNP process. The intricate nature of the doping was elucidated by quantitative electron microscopy and electron paramagnetic resonance spectroscopy. We confirmed that Mn(II) doping is confined to the core of the nanocrystals and that statistically dopants are homogeneously distributed within each nanocrystal. DNP from Mn(II) dopants is then shown to increase 113Cd NMR sensitivity by an order of magnitude, enabling distinction between core and surface environments as well as the detection of defects in the bulk of the nanocrystals. We expect that the approach can be extended to other nanocrystals, providing an efficient route for characterizing their bulk and surface properties.

New tools! GreenPy and ApplePy are fluorescent biosensors for pyruvate with huge responses (20–40x in vitro) and a range of affinities (10s of μM to mM). These should be game changers for imaging of metabolism! Great work by Shosei Imai @sikmys.bsky.social and team 👏. www.biorxiv.org/content/10.1...

Thank you @mirceadinca.bsky.social for visiting us and giving the truly inspiring talk! We learned a lot from you and enjoyed the fun time with you 🍤 Hope to have you again in Tokyo!
@buchergroup.bsky.social and I really enjoyed the ISMAR-ENC dinner at the aquarium. It’s not just aquarium, very artistic. Lovely, precious time…
It was such a wonderful week to meet many great scientists. Many thanks to the organizers and hope to see you all again soon!

We had a farewell party for Bhavesh. He stayed 3 years with us and made a huge contribution for acene-based projects. He was truly wonderful member so we’re very sad to say goodbye 😢
But we should celebrate his new position in Finland, good luck with your new adventure, Bhavesh!
