Engineers at Caltech and JPL have developed a material inspired by chain mail that can transform from a foldable, fluid-like state into specific solid shapes under pressure. "We wanted to make materials that can change stiffness on command," says Chiara Daraio, G. Bradford Jones Professor of Mechanical Engineering and Applied Physics. "We'd like to create a fabric that goes from soft and foldable to rigid and load-bearing in a controllable way." To explore what materials would work best, Daraio, together with former Caltech postdoctoral researcher Yifan Wang and former Caltech graduate student Liuchi Li (PhD '19) as co-lead authors of the Nature paper, designed a number of configurations of linked particles, from linking rings to linking cubes to linking octahedrons (which resemble two pyramids connected at the base). The materials were 3-D printed out of polymers and even metals, with help from Douglas Hofmann, principal scientist at JPL, which Caltech manages for NASA. These configurations were then simulated in a computer with a model from the group of José E. Andrade, the George W. Housner Professor of Civil and Mechanical Engineering and Caltech's resident expert in the modeling of granular materials. [Caltech story]

Joseph Falson, Assistant Professor of Materials Science, has been named as a 2021 Fellow in Materials Synthesis by the Gordon and Betty Moore Foundation. Falson's grant will enable him to pursue methods for growing highly pure crystals of new materials. He plans to build a custom piece of equipment with an ultra-high vacuum chamber corrosive materials that also offers access to the materials so that sensitive experiments may be conducted on them. "Broadly, the field is looking for fundamentally new types of materials that show some type of complex functionality," says Falson. [Caltech story]

Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute, has developed a nano-architected material made from tiny carbon struts that is, pound for pound, more effective at stopping a projectile than Kevlar, a material commonly used in personal protective gear. "The knowledge from this work could provide design principles for ultra-lightweight impact resistant materials for use in efficient armor materials, protective coatings, and blast-resistant shields desirable in defense and space applications," says Greer.

The student winners of the 2021 Demetriades - Tsafka - Kokkalis Prizes were announced at the end of this academic year. David Brown, advised by Professor Viviana Gradinaru and Professor Matt Thomson has received the prize in Entrepreneurship. His research is in molecular and computational strategies for both understanding variability in the human immune system, and characterizing the on- and off-target profile of gene therapy delivery at the resolution of individual cells. Hsiao-Yi Chen, advised by Professor Marco Bernardi has received the prize in Nanotechnology. His research is in the development of ab initio methods to investigate exciton radiative emission and ultrafast dynamics. Tatyana Dobreva, advised by Professor Matt Thomson and Professor Viviana Gradinaru has received the prize in Entrepreneurship. Her research is in single-cell sequencing to interrogate the human immune system, characterize immune response to recombinant Adeno-Associated Viruses (AAVs), and engineer immune cells. Zachary Lee, advised by Professor Steven Low has received the prize in Environmentally Benign Renewable Energy Sources. His research involves developing a suite of tools and algorithms to enable smart electric vehicle charging at scale. Valère Lambert, advised by Professor Nadia Lapusta has received the prize in Seismo-Engineering, Prediction, and Protection. His research is in developing and using physics-based numerical models that combine laboratory insight and theoretical developments to simulate sequences of earthquake ruptures and slow slip that match field observations, thus illuminating physical properties of faults and building towards predictive modeling.

The student winners of the 2021 New Horizons Award were announced at the end of this academic year. Sara Beery was recognized for her passion, energy, and fearlessness to improve the CMS program by founding the Women in CMS group, organizing events and discussions on racism in academia, and advocating for the support structures that improve the educational experience for all CMS students. Abigail (Abby) Jiang was recognized for her commitment to enhance the campus environment through her leadership of the Caltech Asian Pacific Islander Desi American student association (APIDA+) and of PRISM, the Caltech LGBTQ+ association, and her advocacy for other campus diversity initiatives. Daniel Mukasa was recognized for his dedication and leadership of Black Scientists and Engineers of Caltech, which catalyzed campus engagement, reflection, and reform, and for his mentorship of undergraduates through the WAVE program. Alexander Choi, Leah Ginsburg, Marcus Lee and Victoria Lee, were recognized for their collective engagement and sustained dedication to improve the quality of life for MCE graduate students that culminated in the initiation of a seminar series, an option-wide climate survey, the appointment of a Diversity Liaison, the creation of a MCE community statement, and formation of www.deiinitiatives.caltech.edu, a campus-wide data base for DEI activities.

Harry A. Atwater, the Howard Hughes Professor of Applied Physics and Materials Science and director of the Liquid Sunlight Alliance (LiSA), has been selected as the new chair of the Division of Engineering and Applied Science. On July 1, he will begin his five-year term, taking over the Otis Booth Leadership Chair from current division chair Guruswami (Ravi) Ravichandran, the John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering. After more than three decades at Caltech, Atwater says he's looking forward to the opportunity to serve the Institute in a new way. "I'm excited to be able to pay back or pay forward all of the investments that Caltech has made in me," he says. "I'm excited to try to do what I can to catalyze research initiatives that my colleagues are excited to lead, and to make the division as strong and distinctive as possible." [Caltech story]
