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."

Space Solar Power Initiative

04-28-15

Caltech and Northrop Grumman Corporation have signed a $17.5 million sponsored research agreement for the development of the Space Solar Power Initiative (SSPI). The initiative will develop technologies in three areas: high-efficiency ultralight photovoltaics; ultralight deployable space structures; and phased array and power transmission. "The Space Solar Power Initiative brings together electrical engineers, applied physicists, and aerospace engineers in the type of profound interdisciplinary collaboration that is seamlessly enhanced at a small place like Caltech... We are working on extremely difficult problems that could eventually provide the world with new, and very cost-competitive technology for sustainable energy,” said EAS Chair Ares Rosakis.

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]

Professor Faraon Receives NSF CAREER Award

02-05-15

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his 5-year project, “Quantum Light-Matter Interfaces Based on Rare-Earth Ions and Nanophotonics”. The CAREER program is NSF's most prestigious awards for junior faculty members. The level and 5-year duration of the awards are designed to enable awardees to develop careers as outstanding teacher-scholars. Awardees are chosen because they exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.

Professor Scherer Elected to National Academy of Inventors

01-08-15

Axel Scherer, Bernard Neches Professor of Electrical Engineering, Applied Physics, and Physics, has been named fellow of the National Academy of Inventors (NAI). He has most recently developed ways to integrate optics, electronics, and fluidics into sensor systems. Much of his work is currently focused on systems for medical diagnosis and health monitoring through molecular pathology and wireless implants.  Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."
