Atomic Fractals in Metallic Glasses


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


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


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


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]

Postdoctoral Scholar Receives Dissertation Award From American Physical Society


Moureen C. Kemei, Resnick Sustainability Institute Prize Postdoctoral Scholar in Applied Physics & Materials Science, has recieved the American Physical Society's Richard L. Green Dissertation Award in Experimental Condensed Matter or Condensed Matter Physics. The award recognizes her outstanding thesis on "Magnetostructural and Magnetodielectric Coupling in Spinel Oxides" citing her achievement in employing advanced characterization tools to gain new insights into the structure and electronic properties of magnetic materials and solid oxide fuel cell (SOFC) cathode materials. The exploration of SOFC cathode materials is the focus of Moureen’s research at the Resnick Sustianability Institute, which she works on in the lab of Professor Sossina Haile.
