The theme will be Emergent Properties in Nanomaterials. The invited speaker line-up is really exciting! - Deadline for contributed talks: June 27 - Deadline for posters: Sept 22 https://www.nanoge.org/MATSUSFall25/symposia?t=67b4a9da2f09134dd50aa99d13 Jun 2025 09:53 +0000at://did:plc:ydjvinnthdbzhc3nstepnwp2/app.bsky.feed.post/3lri656rbjs25https://bsky.app/profile/jamesutterback.bsky.social/post/3lpjmxb4aes2hPaper #3 from the group! We image thermal transport down to monolayer nanocrystal superlattices. In that regime ballistic phonon transport takes effect. This was possible thanks to the beautiful samples from Florian Schulz. https://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.20250494919 May 2025 13:01 +0000at://did:plc:ydjvinnthdbzhc3nstepnwp2/app.bsky.feed.post/3lpjmxb4aes2hhttps://bsky.app/profile/jamesutterback.bsky.social/post/3lokubw6sms24Now on the front cover of Nano Letters! @pubs.acs.org https://pubs.acs.org/toc/nalefd/25/1807 May 2025 07:20 +0000at://did:plc:ydjvinnthdbzhc3nstepnwp2/app.bsky.feed.post/3lokubw6sms24https://bsky.app/profile/jamesutterback.bsky.social/post/3lmjn4pudxk2vVery excited for the 2nd paper from my group to be out in Nano Letters ! We demonstrate how both charge carriers and heat contribute to pump-probe spectroscopy of nanocrystal films. https://doi.org/10.1021/acs.nanolett.5c0032611 Apr 2025 08:48 +0000at://did:plc:ydjvinnthdbzhc3nstepnwp2/app.bsky.feed.post/3lmjn4pudxk2vhttps://bsky.app/profile/jamesutterback.bsky.social/post/3ld55apbr3s2kVery excited to share the first publication of my independent group in ACS Nano! We control, model and visualize heat transport anisotropy in supercrystals self-assembled from colloidal nanocrystals. Big thanks to the many collaborators! #matsky https://pubs.acs.org/doi/10.1021/acsnano.4c1299112 Dec 2024 20:46 +0000at://did:plc:ydjvinnthdbzhc3nstepnwp2/app.bsky.feed.post/3ld55apbr3s2khttps://bsky.app/profile/jamesutterback.bsky.social/post/3ld3xzdjvbk2lHello Bluesky!
