These videos were taken in an in-situ scanning electron microscope (SEM) equipped with a nanomechanical module. This instrument applies a compressive load to hierarchical nanolattices whose building blocks are composed of self-similar unit cells. These videos highlight the important role of material and architecture in structural meta-materials to elicit diametrically opposite properties - i.e. catastrophic failure vs. recoverability and damage tolerance - when material dimensions are reduced to the nanoscale.
On Wednesday, August 26, Caltech Vice Provost Mory Gharib welcomed 80 mostly high school-age young people who were at Caltech for a U.S. Citizenship ceremony. The ceremony, which was organized by the U.S. Citizenship and Immigration Services and hosted by Caltech, recognizes young people who obtained citizenship through their parents.
Caltech professors Alexei Kitaev and Christopher Umans have been named Simons Investigators. These appointments are given annually to "support outstanding scientists in their most productive years, when they are establishing creative new research directions." Investigators receive $100,000 annually for five years.
On September 1, Guruswami Ravichandran, the John E. Goode, Jr., Professor of Aerospace and professor of mechanical engineering, will become the new chair of the Division of Engineering and Applied Science.
The Moores describe Caltech as a one-of-a-kind institution in its ability to train budding scientists and engineers and conduct high-risk research with world-changing results—and they are committed to helping the Institute maintain that ability far into the future.
As members of Caltech's Engineering Without Borders chapter, a group of Caltech undergraduates are working together this summer to build and implement a gravity flow and slow-sand water filtration system that could provide a reliable supply of clean water for about 100 households.
After serving the last six years as the dean of graduate studies, Joseph Shepherd (PhD '81), the C. L. "Kelly" Johnson Professor of Aeronautics and professor of mechanical engineering, is taking on a new leadership role as the vice president for student affairs.
