Ceci n’est pas une jellyfish
Label Ceci n’est pas une jellyfish Artist Erica Knorr Description As a perylene diimide derivative dried, it formed crystals in the bottom of the vial. A portion of those crystals made an interesting shape. These molecules will eventually be used for a singlet fission solar cells. Type DSLR, image cropped and background changed in photo-editing…

Filtered Fluorescence
Label Filtered Fluorescence Artist Alex Robb Description Photon upconversion is the process of converting low-energy photons into higher energy ones. This has proven to be useful in a wide variety of applications, but especially for solar energy conversion in which most of the low energy photons from the sun can not be absorbed effectively, thus…

The Creation of Color
Label The Creation of Color Artist Carl Conti Description A molecular dye (left, red) and plasmonic nanorods (right, blue) come together to illustrate the different ways colors arise. The dye relies on the excitation of electrons from pi to pi* orbitals, while the nanorods exhibit their unique color due to the coupling of incoming light…
