Early life and education

edit

Yang was born in China. She attended Fudan University in Shanghai.[1] She moved to the United States for graduate studies, where she joined Cornell University as a student in chemistry and chemical biology. She remained at Cornell for her doctoral research, where she worked on the design and synthesis of novel polymers for microelectronics.[2] After graduating, she joined Bell Labs as a member of the Lucent Technologies.[3]

Research and career

edit

In 2004, Yang joined the faculty at the University of Pennsylvania.[4] She was promoted to Professor in 2013 and elected Chair in 2021. Yang is interested in the synthesis and fabrication of novel materials, including self-assembled nanostructures and responsive materials.[5] Through the study of lotus leaves and butterflies, Yang created novel superhydrophic surfaces.[6] These surfaces have very high nanoscale roughness, which reduces the contact area between water and results in water being repelled from the surface.[6] Superhydrophic surfaces could be used to keep the outside of buildings and solar panels dry and clean.[6][7] To fabricate these surfaces, Yang pioneered the use of holographic lithography, using a laser to cross-link a photoresist.[6] Areas of the photoresist that are not illuminated by the laser are removed by a solvent, leaving a 3D network behind.[6] She optimized the structure of the network using a combination of good and bad solvents.[6] Through the study of photosymbiotic giant clams, Yang worked with Alison Sweeney on the development of solar concentrators.[8][9][10] By introduce molecular ordering in two-dimensional sheets of a rubber-like material called liquid crystal elastomer, the Yang lab transforms the sheets into complex three-dimensional geometries, such as a human face, with heat. [11] She is investigating self-morphing building blocks for novel manufacturing processes.[12] These building blocks are based on biological systems and natural materials. For example, by studying snail slime she created a novel, reversible adhesive.[13] By introducing holes and cuts in 2D sheets, Yang demonstrates dramatic color and shape change and super-conformability via collapsing or expanding of the hole arrays in the micro- and macroscales. By programming the geometry of cuts and fold using origami and kirigami mechanisms, Yang explores potential applications in water harvesting, super-stretchable and shape conformable medical devices.

During the COVID-19 pandemic, Yang was part of a team who created an origami-inspired face mask that could be used to address the shortage of personal protective equipment in hospitals. She shared the design through Open Medical[14] and recommended the respirators be made using sterilisation wrap. The mask achieved a 95% viral filtration efficiency.[14]
