Penn Physicists Develop Force Law for Granular Impacts: Sand, Other Granular Matter's Behavior Is Better Defined
April 20, 2007
PHILADELPHIA -- Sand.  A single grain is tiny, but solid, and shares the physical properties of other solid matter.  But pack or transport millions of grains together - as modern society does with coffee grounds, flour and industrial chemicals - and granular materials act differently, baffling engineers.  They take the shape of their containers and flow freely, like liquids.  In certain circumstances, they exert pressure like a gas.  The basic lack of behavioral knowledge contributes to wasted resources and energy, as well as erosion and other natural phenomena.  
Penn Professor Awarded 2007 Guggenheim Fellowship
April 18, 2007
PHILADELPHIA -- Sanjeev Khanna, professor of computer and information science at the University of Pennsylvania, has been honored with a 2007 Guggenheim Fellowship. Khanna works in theoretical computer science at the interface of algorithms and computational complexity.  The fellowship will fund his continued research to identify the polynomial-time approximability of fundamental problems in combinatorial optimization.
Behold RAVI-Bot! Penn Students Build Improvisational Robot That Plays Classical Indian Music
April 12, 2007
PHILADELPHIA -- RAVI-bot, a senior design project built by mechanical engineering students of the University of Pennsylvania, is an electromechanical, robotic sitar that mimics the techniques and improvisational style of the North Indian Hindustani classical stringed instrument. Part of ArtBots 2007, an international robotic talent show held this year in Philadelphia, RAVI-Bot will be on display beginning April 13 at the Esther M. Klein Art Gallery at the University City Science Center, 3701 Market St. in Philadelphia.  
Cell Structures Exhibit Novel Behaviors, Mimic Red Blood Cells and Liquid Crystals, Penn Researchers Report
April 10, 2007
PHILADELPHIA -- Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.
Seeking the Next Kevlar: Penn Researchers Fine Tune Nanotube/Nylon Composite Using Carbon Spacers
April 4, 2007
PHILADELPHIA - A team of University of Pennsylvania and Rice University researchers have added a significant new step to the creation of materials fortified by single-walled carbon nanotubes, or SWNTs, resulting in a nylon polymer composite with greater strength and toughness and opening the door for researchers to broadly improve the mechanical properties of such composites at the molecular level.
