Engineers Create Artificial Skin That "Feels" Temperature Changes

01-30-17

Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed an artificial skin capable of detecting temperature changes using a mechanism similar to the one used by the organ that allows pit vipers to sense their prey. [Caltech story]

Professor Bhattacharya Named Vice Provost

07-14-16

On July 15, 2016, Kaushik Bhattacharya, Howell N. Tyson, Sr., Professor of Mechanics and Materials Science, will take over from Professor Morteza Gharib as Caltech vice provost. His research group studies the mechanical behavior of solids and uses theory to guide the development of new materials. He has made contributions on a wide array of topics, ranging from the fundamental mechanics of materials, to active materials and devices, to multi-scale and multi-physics scale simulation of materials. Though trained as a theoretician, he is well known for live demonstrations of shape-memory materials in action.  "Kaushik's technical strength, deep knowledge of the Institute, energy, and enthusiasm will serve him and us well as he takes on this important role," said EAS Division Chair G. (Ravi) Ravichandran. [Caltech story]

Winners of the 2016 Demetriades - Tsafka - Kokkalis Prizes Announced

06-09-16

The student winners of the 2016 Demetriades - Tsafka - Kokkalis Prizes were announced at a special dinner with the Demetriades - Tsafka – Kokkalis family. Rachel P. Galimidi received the prize in Biotechnology for her work with Professor Pamela Bjorkman aimed to further understand the mechanism of HIV evasion of the humoral immune response. Junle Jiang was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Nadia Lapusta which used probabilistic inversion tools to understand the deep-ocean trench generated tsunamis that occurred during the subduction-zone earthquakes in Japan and Chile. Yinglu Tang working with Dr. Jeff Snyder received the prize in Environmentally Benign Renewable Energy Sources for her work on thermoelectric skutterudites for mid-temperature applications such as automotive waste heat recovery. The second winner in this category was Changhong Zhao who worked with Professor Steven Low to study the control and optimization of modern electric power systems. The winner of the prize in Nanotechnology was Gustavo Rios whose research involves development of a modular, scalable, nanofabricated neural probe system for dense 3-D electrophysiology to study animal brains. Rio’s graduate advisor was Professor Thanos Siapas. The prize in Entrepreneurship was given to Anton A. Toutov who was advised by Professor Robert Grubbs. His research interests lie in using fundamental chemistry to development radically new, sustainable ways to make everyday chemical products and generate clean energy.

Tiny Diatoms Boast Enormous Strength

02-08-16

Researchers in the lab of Julia R. Greer, Professor of Materials Science and Mechanics, have recently found that diatom shells have the highest specific strength—the strength at which a structure breaks with respect to its density—of any known biological material, including bone, antlers, and teeth.

Atomic Fractals in Metallic Glasses

09-18-15

Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues including graduate student David Chen have shown that metallic glasses has an atomic-level structure although it differs from the periodic lattices that characterize crystalline metals. "Our group has solved this paradox by showing that atoms are only arranged fractally up to a certain scale," Greer says. "Larger than that scale, clusters of atoms are packed randomly and tightly, making a fully dense material, just like a regular metal. So we can have something that is both fractal and fully dense."

Professor Minnich Receives Young Investigator Award

05-01-15

Austin Minnich, Assistant Professor of Mechanical Engineering and Applied Physics, has won a 2015 Office of Naval Research (ONR) Young Investigator Award. The objectives of the Young Investigator Program are to attract to naval research outstanding new faculty members, to support their research, and to encourage their teaching and research careers. Professor Minnich’s award is for his proposal entitled, “Investigation of the Atomistic Mechanisms Governing Heat Conduction in Polymers.” [List of Recipients]

Women Making History

03-13-15

In celebration of Women’s History Month, influential women leaders from the Jet Propulsion Laboratory (JPL) and Caltech gathered at the JPL von Karman auditorium. Present at the event, entitled Women Making History, were the 2015 honorees for Women@JPL as well as Caltech faculty and staff. It was an opportunity for women at different stages of their career to meet and network. EAS faculty were represented by Professors Bordoni, Greer, and Hunt.  The JPL Advisory Council for Women was the lead organizer of the event.

Tiny Lattices with Enormous Potential

02-18-15

Professor Julia Greer’s work on nanolattices is part of the 2015 MIT Technology Review’s 10 Breakthrough Technologies List. The list identifies the ten milestones from the past year that solve difficult problems or create powerful new ways of using technology. Professor Greer was selected for her work on nanomaterials and specifically “materials whose structures can be precisely tailored so they are strong yet flexible and extremely light.” [Learn more]
