Early life

Cui was born in Laibin, Guangxi, China. He obtained his B.S. in Chemistry from the University of Science and Technology of China in 1998. He pursued his graduate study in physical chemistry with Charles M. Lieber at Harvard University and obtained his Ph.D. in 2002. At Harvard, he pioneered nanoscale sensors and devices for highly sensitive detection based on the silicon nanowire technology[12][13]. After that, he went to work as a Miller Postdoctoral Fellow with A. Paul Alivisatos at the University of California, Berkeley. At Berkeley, he worked on electronic property and assembly of colloidal nanostructures[14][15]. In 2005, he joined the Department of Materials Science and Engineering at Stanford University as an assistant professor and started to pursue energy and environment-related research. He was granted tenure in 2010 and promoted to full professor in 2016[16].

Research and career

In 2004, Steven Chu became the director of Lawrence Berkeley National Laboratory, where Chu launched several major initiatives centered on clean energy. Influenced by Chu's advocate on energy and climate change during his postdoctoral study at Berkeley, Cui decided to dedicate his Stanford lab to clean energy research and related topics. In 2008, his team reported "High-performance lithium battery anodes using silicon nanowires"[17], which triggered global interests in the use of nanotechnology and nanomaterials for energy storage[18]. Over the years, he has largely contributed to materials design for high energy-density batteries[19], grid-scale storage[20], and the safety of batteries[21]. His group also covers a diverse array of research topics, such as solar cells[22], two-dimensional materials[23], electrocatalysis[24], textile engineering[25], water technology[26], air filtration[27], soil cleanup[28], and bio-nano interface[29][30].

In 2016, Cui took inspirations from structural biology and employed Cryo-EM to image batteries at an atomic resolution for the first time[31]. The high-resolution imaging unveiled the nature of lithium dendrites, providing mechanistic insights into the nanostructure of solid-electrolyte interphase (SEI)[32]. Currently, his group is implementing Cryo-EM to probe atomic and molecular details in the metal-organic framework[33], perovskite[34], and other nanomaterials.

During the recent COVID-19 pandemic, Cui assembled a team with Steven Chu to investigate the reuse of respirators and face masks after different disinfection treatments.[35][36]. They reported that heat (70°C for 30 min, 75°C for 30 min, 85°C for 20 min, or <100°C)  (dry and various humidities) could be used to disinfect N95-level respirators for 50 cycles without a loss of filtration efficiency[37]. It has been reported that a 30-minute exposure to 65°C heat is sufficient to eradicate SARS-CoV-2 in solution[38]. Cui and coworkers are now working towards the tests of dry heat on SARS-CoV-2.

Cui has established close collaboration with a number of Stanford faculty, including Steven Chu, Zhenan Bao, Robert Huggins, William Nix, Shanhui Fan, Bianxiao Cui, Harold Y. Hwang, Craig Criddle, Alexandria Boehm, Mark Brongersma, Michael McGehee, Zhi-Xun Shen, Shoucheng Zhang, Michael Toney, and Hongjie Dai, as well as Gang Chen from MIT.

He has also founded three companies to commercialize the technological breakthroughs from his research group: Amprius Inc.[39], 4C Air Inc.[40], and EEnovate Technology Inc[41].

Business activities

In 2008, Cui founded Amprius Technologies[39] to commercialize silicon anodes for high energy density lithium-ion batteries. Over the past decade, the original concept developed by Cui's team has evolved into the first commercially produced lithium-ion battery that employs a 100% silicon nanowire anode with breakthrough performance approaching 500 Wh/kg over hundreds of cycles. Amprius has recently partnered with Airbus to boost the development of next-generation batteries based on Silicon Nanowire Anode technology.[71]

In 2015, Cui co-founded 4C Air Inc.[40], together with Steven Chu, aiming to bring clean air through innovative nanomaterials. This establishment was motivated by the increased morbidity and mortality associated with air pollution, mostly in developing countries. In particular, particulate matter with a diameter lower than 2.5 microns (PM2.5) is the most consistent and robust predictor of mortality in studies of long-term exposure. 4C Air harnesses the technology developed at Cui's group at Stanford and is currently developing products and solutions for PM2.5.

In 2017, Cui founded EEnovate Technology to develop nanotechnology for energy-related and environmental issues, including water purification, grid-scale energy storage, and smart wearable textiles. Recently, EEnovate is recognized by "Start-up City Magazine" as one of the most promising start-ups in 2019 for its wearable technology.[72]

Anecdotes

Cui is an avid soccer player and plays midfielder to orchestrate offense and defense. He currently serves on the board of Asian-American Youth Soccer Academy (AAYSA)[73], a non-profit agency in San Francisco.

gollark: Anyway, Nim is quite cool. It is like Python but compiled and more strongly typed, plus macrons.
gollark: Is this related to whatever bizarre encoding scheme they use?
gollark: My device is still warrantied but not having a laptop for ages while it gets repaired would be very inconvenient, so does anyone know how long this sort of thing generally takes to get fixed (or if there is a simple repair I can do, but I doubt it)?
gollark: I heard a "pop" noise earlier today when using my laptop (Legion 5, 2020, RTX 2060, i5-10300H), and it seems that now heavy GPU load causes a weird periodic buzzing noise (attached; sorry for the poor quality but I had to boost the volume lots for it to be audible, and also the recording is mostly fan noise). I figure it's a GPU power supply issue.
gollark: Discrete = always use dedicated GPU, dynamic = sometimes use integrated GPU, probably.
