Yanan Li
Yanan completed her BS in Chemistry at Nanjing Normal University in 2015, before earning her MS in Inorganic Chemistry at Beijing Normal University in 2018. There she worked with Xiaojing Yang on 2D nanocomposites and the controllable assembly of inorganic nanosheets. Yanan's current research is focused on developing Pb-free perovskites and the crystallization behavior of perovskites for solar cell applications.
In her spare time, Yanan enjoys traveling and cooking.

FACILITIES & EQUIPMENT
We have fantastic facilities throughout campus including the Kuiper imaging core, X-ray diffraction facility, Keck center for nano-imaging, Laboratory for electron spectroscopy and surface analysis (LESSA), and the Micro/Nano fabrication and Optical sciences cleanrooms. Additionally, we have the following equipment available in our lab:
Gloveboxes
We have two Vigor SciLab gloveboxes connected by a T-antechamber, which we use for making solutions of moisture and oxygen sensitive materials and fabricating devices in an inert environment.
Electrospinner
Inovenso NE100 with temperature and humidity control, capable of creating polymer fibers with diameters on the order of 100 nm. This machine is capable of spinning two materials simultaneously, either as separate fibers or in a core-shell configuration.
Thin Film Stress Analyzer
We have a K-Space ThermalScan TS25 (the first of its kind!) capable of measuring residual film stresses on small substrates over a wide range of environmental conditions.
Spectrofluorometer
Our Horiba Fluorolog-3 Spectrofluorometer is capable of measuring both steady-state and time-correlated single photon counting of fluorescent emission from thin films and solutions.
Environmental Chamber
Devices can be aged in our Weiss Technik Endurance 180/40 Environmental Chamber, from -40 C to 180 C with relative humidities up to 98%.
Solar Simulator
We have an OAI TriSol TSS-100US AAA solar simulator capable of AM1.5G conditions over a 100 mm by 100 mm area.
Adhesion/Cohesion Tester
Our DTS Delaminator is used for testing the adhesion and/or cohesion of thin films in single cantilever, double cantilever, three-point bending, or four-point bending configurations; samples can be tested in ambient or at varying environmental conditions.
Tensile Tester
With our Mark-10 tensile tester, we can measure the stress/strain responses of bulk materials, giving us information about their Young's modulus, yield point, ultimate tensile strength, and toughness.
Stretch Station
We use a highly precise Newmark linear actuator to drive our purpose-built testing setups for measuring the stress-strain response of thin films. We can determine the tensile modulus, yield point, and crack-onset strain for film-on-elastomer systems of all kinds.
Contact Angle Goniometer
Krüss contact angle goniometer with two automated dispensers and a tilt table for measuring the surface energies of materials under different conditions.
Spin Coaters
We have several Laurell spin coaters, in ambient and inert conditions for thin film fabrication.
Plamsa Cleaner/Etcher
We have an OptiGlow ACE system capable of generating plasmas from 10 to 150W, useful for cleaning surfaces, preparing them for functionalization, PDMS bonding, or etching.
3D Printer
Epax X1 SLA 3D printer for rapid prototyping of parts and experimental setups.
Vacuum Oven
Our vacuum oven is used for heating and drying a range of materials and samples.
