Electrical Vehicle Design and Racing

02-12-16

The students in the CS/EE/ME 75 class, Introduction to Multidisciplinary Systems Engineering, invited industry experts to their midterm design review on the evening of February 11, 2016. The students are currently in the manufacturing phase and plan to finish the vehicle frame this week and attach the mounting brackets shortly thereafter. They aim to have a running prototype electrical vehicle by mid-March to get early testing data before refining their design for the upcoming Formula SAE competition. The course is co-taught by Professors Guillaume Blanquart, Azita Emami, and Richard Murray as well as the Executive Director for the Resnick Institute, Neil Fromer. Several students in the course are also members of the Caltech Sustainable Vehicle Club led by undergraduate student Robert Anderson. [Huffpost Education Blog]

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.

Cancer Treatment in a Painless Patch

11-05-15

Mechanical engineering undergraduate student, Teo Wilkening, spent this past summer working with Professor Gharib to test the preliminary design for an alternative—and possibly much less painful—method of chemotherapy drug delivery through a patch. To avoid the pain caused by the large needle traditionally used for such an intravenous injection, the team envisioned a patch containing hundreds of micrometer-scale needles, too small in diameter to be sensed by the nerves in the skin.

Extending a Battery's Lifetime with Heat

10-03-15

The research of alumnus Asghar Aryanfar (’15 PhD, ME) along with Professors Goddard and Hoffmann has shown that heat can break down the damaging branch-like structures that grow inside batteries, which may possibly be used to extend battery lifetimes. [Learn more] [Read the paper]

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."

New EAS Division Chair Announced

08-03-15

Guruswami Ravichandran, John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering; Director, Graduate Aerospace Laboratories, has been selected as the new chair of the Division of Engineering and Applied Science (EAS) effective September 1, 2015. "I believe, based on the evaluation of the search committee and on my own interactions with him, that Ravi not only has the judgment, energy, and vision to lead the division creatively and effectively, but that he will also be an outstanding advocate for the division," said Edward Stolper, Carl and Shirley Larson Provostial Chair and William E. Leonhard Professor of Geology, in an announcement to the EAS faculty. Professor Ravichandran commented, "During my tenure, I would like to see that we attract the best faculty and students to EAS and the Institute who will enable interdisciplinary activities across Caltech and contribute to frontiers of engineering science and technology. I would like to see a more diverse body of students and faculty, who will enrich EAS and the Institute, and I would like to see EAS be at the forefront of technological revolution based on our unique ability to drive advances through basic research.” [Caltech Release]
