As part of the Science Journeys lecture series—designed to inspire scientific curiosity, especially among students in eighth grade and higher—graduate student Fernando Villafuerte discussed his path to Caltech and his research on batteries, including their role in sustainability solutions. Villafuerte works in the lab of Julia R. Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; and Fletcher Jones Foundation Director of the Kavli Nanoscience Institute. His research focuses on a novel material known as a solid polymer electrolyte, which could potentially be used to create batteries that can store more energy than currently possible. [Caltech story]

Adaptive electric vehicle chargers and advanced battery designs are some of the ways Caltech researchers are building a more sustainable electric grid. Steven Low, Frank J. Gilloon Professor of Computing and Mathematical Sciences and Electrical Engineering, invented the Adaptive Charging Network (ACN). But Low and others warn that this grid is unprepared for the challenges of the 21st century. “The current grid will very soon hit a wall where, when we add renewable energy, it sits unused because the demand isn’t there at a time when the solar is running,” says Adam Wierman, Professor of Computing and Mathematical Sciences; Director, Information Science and Technology. That is why Caltech researchers are working on ways to break down that barrier to help empower an energy transformation. 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, is pushing the limits of the batteries themselves.  [Caltech story]

Caused by collisions from asteroids, comets, and other astronomical objects, lunar craters give our moon its characteristic pockmarked façade. These craters hold the materials necessary for building sustained human settlements on the moon. Accessing the materials inside lunar craters is no easy task. NASA seeks new ways of getting around the moon that do not rely on wheels. The agency's Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge asks university teams to go beyond wheeled rovers and create new solutions to the problem of traversing lunar craters. A team of more than 30 Caltech undergraduates in the Division of Engineering and Applied Science is among seven 2022 BIG Idea finalists. [Caltech story]

A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which the light strikes the material. "Negative refraction is crucial to the future of nanophotonics, which seeks to understand and manipulate the behavior of light when it interacts with materials or solid structures at the smallest possible scales," says 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. [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.

Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them—and for the first time, the technology works regardless of seasonal changes to that terrain. The general process, known as visual terrain-relative navigation (VTRN), was first developed in the 1960s. By comparing nearby terrain to high-resolution satellite images, autonomous systems can locate themselves. The problem is that, in order for it to work, the current generation of VTRN requires that the terrain it is looking at closely matches the images in its database. To overcome this challenge, Anthony Fragoso, Lecturer in Aerospace; Staff Scientist, Connor Lee, Graduate student in Aerospace, Austin McCoy, Undergraduate, and Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems and research scientist at JPL, turned to deep learning and artificial intelligence (AI) to remove seasonal content that hinders current VTRN systems.

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.
