EAS Remembers Allan Acosta

05-19-20

Allan Acosta, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering, Emeritus, who spent 50 years at Caltech and helped launch the Institute's present day Mechanical Engineering option, passed away on May 18, 2020 at the age of 95. Allan joined the faculty in 1954 after having obtained his BS '45, MS '49, and PhD '52 degrees in Mechanical Engineering from Caltech. He collaborated with Chris Brennen on a project for NASA to eliminate the instability caused by a phenomenon known as "pogo oscillation" from the Space Shuttle design. Allan was a much-admired teacher and mentor who influenced many generations of students. He served as the Executive Officer of Mechanical Engineering from 1988 to 1993. He was the author of a popular textbook, Fluid Flow: A First Course in Fluid Mechanics, which he co-authored with Rolf Sabersky. Allan received numerous honors and awards, including election as a member of the National Academy of Engineering and as a Fellow of the American Association for the Advancement of Science.

Amphibious Robots Storm Millikan Pond for ME 72

03-18-20

Caltech's annual engineering design competition returned for its 35th installment. Five teams of Caltech undergraduates spent months building three amphibious remote-controlled robots per team that could drive into Millikan Pond and speed across the water to drop, shoot, or push balls into targets and outscore the opposing team. It was a high-stakes afternoon of capsizing, cheering, and triumph. [Caltech story]

Microstructures Self-Assemble into New Materials

03-03-20

A new process developed at Caltech makes it possible for the first time to manufacture large quantities of materials whose structure is designed at a nanometer scale—the size of DNA's double helix. Pioneered by Professor Julia R. Greer, "nanoarchitected materials" exhibit unusual, often surprising properties—for example, exceptionally lightweight ceramics that spring back to their original shape, like a sponge, after being compressed. Now, a team of engineers at Caltech and ETH Zurich have developed a material that is designed at the nanoscale but assembles itself—with no need for the precision laser assembly. "We couldn't 3-D print this much nanoarchitected material even in a month; instead we're able to grow it in a matter of hours," says Carlos M. Portela, Postdoctoral Scholar. "It is exciting to see our computationally designed optimal nanoscale architectures being realized experimentally in the lab," says Dennis M. Kochmann, Visiting Associate. [Caltech story]

Team CoSTAR Takes First Place in Underground Robot Competition

02-27-20

A team including Caltech researchers and JPL earned top honors in the DARPA Subterranean Challenge. Whether robots are exploring caves on other planets or disaster areas here on Earth, they need to be able to navigate a location and seek out objects of interest without access to GPS or human guidance. The Subterranean Challenge tests this kind of cutting-edge technology. "One of the two courses we had to run had multiple levels, so it was great that the Boston Dynamics robots were fantastic on stairs," says Joel Burdick, the Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering and JPL research scientist, and the leader of the Caltech campus section of the CoSTAR team. [Caltech story]

Ultrasound Can Selectively Kill Cancer Cells

02-05-20

Professor Michael Ortiz and Professor Morteza Gharib are exploring a new technique that could offer a targeted approach to fighting cancer. Low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. In the past, ultrasound waves have been used as a cancer treatment with high-intensity bursts resulting in killing cancer and normal cells. [Caltech story]

Professor Rosakis Elected Laureate of the Aurel Stodola Lecture

02-05-20

Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering has been elected as the Laureate of the Aurel Stodola Lecture and presented with the Aurel Stodola Medal. The Aurel Stodola Lecture Series commemorates the contributions of Professor Aurel Stodola in the early 20th century whose work on applied thermodynamics has guided many engineers and engineering developments worldwide. "Ares Rosakis possesses this unique ability to develop new experimental methods to make extremely fast mechanical processes (such as those occurring during earthquakes) tangible and observable in the laboratory," says Bradley Nelson, Professor of Robotics and Intelligent Systems and Head of D-MAVT.
