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.

New Algorithm Helps Autonomous Vehicles Find Themselves, Summer or Winter
06-24-21
Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them—and for the first time, the technology works regardless of seasonal changes to that terrain. The general process, known as visual terrain-relative navigation (VTRN), was first developed in the 1960s. By comparing nearby terrain to high-resolution satellite images, autonomous systems can locate themselves. The problem is that, in order for it to work, the current generation of VTRN requires that the terrain it is looking at closely matches the images in its database. To overcome this challenge, Anthony Fragoso, Lecturer in Aerospace; Staff Scientist, Connor Lee, Graduate student in Aerospace, Austin McCoy, Undergraduate, and Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems and research scientist at JPL, turned to deep learning and artificial intelligence (AI) to remove seasonal content that hinders current VTRN systems.

Harnessing Sound for Health: A Conversation with Tim Colonius
06-18-21
When a person develops a kidney stone or a gall stone—hard accumulations of minerals and other compounds created by the body—they can experience a great deal of pain and discomfort. Lithotripsy is the practice of breaking gall or kidney stones into small pieces within the body using shockwaves produced by a machine called a lithotripter. A new form of lithotripsy has been under development with the help of Tim Colonius, Frank and Ora Lee Marble Professor of Mechanical Engineering. [Caltech story]

Simon Toedtli Receives 2021 Richard B. Chapman Memorial Award
06-17-21
Simon Toedtli, a graduate student working with Professor Beverley McKeon, is the recipient of the 2021 Richard B. Chapman Memorial Award. His doctoral research combined direct numerical simulations and modal analyses to investigate the physics of closed-loop wall transpiration in a turbulent channel flow and to build low-order flow models for controller design. Both aspects contribute towards the development of drag-reducing control schemes for engineering applications, and will help make future transportation vessels more sustainable. Simon is continuing his studies in fluid mechanics as a postdoctoral fellow at Johns Hopkins University, where he will work on data assimilation for turbulent flows. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
