Winners of the 2023 Demetriades - Tsafka - Kokkalis Prizes Announced

06-02-23

The Demetriades - Tsafka - Kokkalis Prizes are awarded annually to PhD candidates selected for the best thesis, publication, or discovery in select fields. Saransh Sharma, advised by Professor Azita Emami, has received the prize in Biotechnology or Related Fields for his research in developing ultra-low power and highly miniaturized medical electronics for in-vivo localization and tracking. Nathaniel Wei, advised by Professor John Dabiri, has received the prize in Environmentally Benign Renewable Energy Sources or Related Fields for his research that explores the ways in which unsteady flows in the atmosphere can be leveraged in wind-energy systems for enhanced performance, robustness, and operational longevity. Rebecca Gallivan, advised by Professor Julia Greer, has received the prize in Nanotechnology or Related Fields. Coupled with the development of novel materials processing, Gallivan's research focuses on uncovering fundamental insight into the relationship between length-scale and microstructural features on nanomechanical phenomena in order to lay the foundation for advanced engineering and complex design of materials in nanotechnologies.

New Process Allows 3-D Printing of Microscale Metallic Parts

12-01-22

Engineers at Caltech have developed a method for 3-D printing pure and multicomponent metals, at a resolution that is, in some cases, an order of magnitude smaller than previously possible. "We had to develop a new way of doing it, and we couldn't rely on heat to build our structures," says Max Saccone. [Caltech story]

Beaming Clean Energy From Space

10-26-22

Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]

A Science Journey with Fernando Villafuerte

04-26-22

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]

Nano-architected Material Refracts Light Backward—An Important Step Toward One Day Creating Photonic Circuits

02-01-22

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]

Nano-Architected Material Resists Impact Better Than Kevlar

06-25-21

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.
