2019/01/17 - HERMAN's high-temperature reactor installed
posted Feb 11, 2019, 1:46 AM by Emory Chan
The custom-designed, high-temperature microplate reactor for our HERMAN robot has passed its acceptance test and has been officially installed in HERMAN! Thanks to Kyle, Duane and Gary at Aslin Automation for making this happen! It's been a long journey, from an intern prototype, a couple robot vendors, and six Aslin prototypes, but we now have a reactor! Now for the fun part: programming.
2019/01/13 - Ayelet & Bella's upconverting nanopartice lifetimes research published in JPCC
posted Feb 11, 2019, 1:43 AM by Emory Chan
Ayelet and Bella's manuscript investigating the power-dependent lifetimes and energy transfer networks in upconverting nanoparticles was published in the Journal of Physical Chemistry C. They show that UCNPs are complex energy transfer networks with collective, robust, non-linear dynamics. Congrats, Ayelet and Bella!

2018/08/12 - A flood of good and bad news...
posted Feb 11, 2019, 1:13 AM by Emory Chan
The Chan group was hit by a literal and figurative deluge last week. Early in the week, Emory and Irene welcomed the littlest member of the Chan group into the world, Baby Sydney!
But late in the week, the entire Foundry flooded when the sprinklers were set off, sending water raining down all over HERMAN, WANDA, and the rest of the 4th floor. Fortunately, due to the heroic efforts of the Foundry staff, we seemed to have escaped major damage (thank you Nate, Shaul, and the robot gloveboxes!). I guess we'll chalk that up to another stroke of good luck!
