Practicing a conference talk, defense, or job talk? As the saying goes, "Practice doesn't make perfect, perfect practice makes perfect." Here are 10 #ProTips for practicing talks: 🧵

Scientists are innovative in the lab but bound by tradition when presenting that science. Last week, for my #PhDone defense, I tried 2 tweaks in hopes of improving learning and equity. Here’s what I did, how it went, and how to do better. A 🧵

What happens when phonon energy of nanocrystals is low, i mean, veeery low? All sorts of crazy upconversion emerges! Read about it here👇Huge thanks to the whole team behind this project!

Open postdoc positions in the Chan group. Come join our team!

New ways to make MXenes directly (no etching required). Congrats to Di and co.!

Check out our latest work in nature! We show that photon avalanching nanoparticles can be switched on and off repeatedly using light, which allows us to perform <1 Å accuracy super-resolution imaging and 3D nanopatterning. nature.com/articles/s4158… (open access link in 🧵)

Have an emitter that you want to imbue with nonlinear optical properties? Maybe use this approach to transfer avalanching properties from UCNPs to it! Cool work spearheaded by Artiom Skripka and done in the Chan group (Emory Chan). pubs.acs.org/doi/full/10.10…

Say you have some colloidal nanoparticles that would be made even more useful if you could place them with micro/nanoscale precision. If so, try using one of these stimuli-sensitive ligands that I and others (in Talapinlab@uchicago and beyond) have developed! pubs.acs.org/doi/10.1021/ac…

Check our latest work in Nano Letters using machine learning to accelerate the design of upconverting nanoparticle heterostructures. This HPC/Monte Carlo pipeline was able to learn decades worth of UCNP knowledge in the span of 1-2 weeks! 🧵doi.org/10.1021/acs.na…
