Infrared nanosensors of pico- to micro-newton forces
Natalie Fardian-Melamed, Artiom Skripka, Changhwan Lee +9
Mechanical force is an essential feature for many physical and biological processes.1-12 Remote measurement of mechanical signals with high sensitivity and spatial resolution is ne…
Indefinite and Bidirectional Near Infrared Nanocrystal Photoswitching
Changhwan Lee, Emma Z. Xu, Kevin W. C. Kwock +14
Materials whose luminescence can be switched by optical stimulation drive technologies ranging from superresolution imaging1-4, nanophotonics5, and optical data storage6-8, to targ…
Giant nonlinear optical responses from photon avalanching nanoparticles
Changhwan Lee, Emma Xu, Yawei Liu +10
Avalanche phenomena leverage steeply nonlinear dynamics to generate disproportionately high responses from small perturbations and are found in a multitude of events and materials,…
