CHIP Goes to Washington

09-06-11

The high-tech house built by a joint team of students from Caltech and the Southern California Institute of Architecture (SCI-Arc), known as Compact Hyper-Insulated Prototype (CHIP), is heading to Washington D.C. for the 2011 Solar Decathlon competition. The SCI-Arc / Caltech team has been supported by a variety of people including Richard Murray, Thomas E. and Doris Everhart Professor of Control and Dynamical Systems and Bioengineering, and Harry Atwater, Howard Hughes Professor and Professor of Applied Physics and Materials Science; Director, Resnick Sustainability Institute. CHIP will be competing with 18 other teams for the title of the most energy-efficient, affordable, and attractive house. [Caltech Feature] [Walkthrough video of CHIP]

Building A Wind Tunnel To Produce Shear Flow

08-24-11

Summer Undergraduate Research Fellowship (SURF) student, Yuyang Fan, working with Research Scientist Daegyoum Kim and Professor Morteza Gharib, has built a wind tunnel that produces shear flow—flow in which wind speed changes with position or time.  The tunnel is six feet long, four feet wide, and four feet tall.  It is made from 100 coaster-sized computer fans that blow air at around nine meters per second.

Nano-mechanics of Carbon Nanotube Research Wins Art Competition

08-22-11

Siddhartha (Sid) Pathak, a W. M. Keck Institute for Space Studies (KISS) Postdoctoral Fellow in Material Science, has received the first prize in the NanoArt 2011 International Competition. The inspiration for Dr. Pathak's entry entitled "In-situ SEM deformation of CNT micro-pillars" is his research on nano-mechanics of carbon nanotubes.  As a KISS postdoc Dr. Pathak is working with  Professor Julia Greer on mechanical testing of carbon nanotubes at submicron length scales, with a particular emphasis towards space applications.

Intel Acquires Company Founded by CMS Alumni

08-19-11

Fulcrum Microsystems Inc., a company founded by former students of Professor Alain J. Martin, has been acquired by Intel Corporation. Computing and Mathematical Sciences (CMS) alumni Uri V. Cummings (Ph.D. '05) and Andrew M. Lines (M.S. '95) founded Fulcrum Microsystems in late 1999 to commercialize on the nearly two decades of work that they and Professor Martin had done to come up with clockless, low-power, high-bandwidth chips for managing switched communications.

Disorder Is Key to Nanotube Mystery

08-12-11

William A. Goddard III, Charles and Mary Ferkel Professor of Chemistry, Materials Science, and Applied Physics; and Posdoctoral Scholar Tod Pascal believe to have solved the mystery of why water spontaneously flows into extremely small tubes of graphite or graphene, called carbon nanotubes.  Using a novel method to calculate the dynamics of water molecules they have found that entropy is the missing key.  "It's a pretty surprising result," says Professor Goddard "People normally focus on energy in this problem, not entropy."

Engineers Solve Longstanding Problem in Photonic Chip Technology

08-04-11

Liang Feng, a Postdoctoral Scholar in Electrical Engineering who works with Professor Axel Scherer, has designed a new type of optical waveguide - a 0.8-micron-wide silicon device. The waveguide allows light to go in one direction but changes the mode of the light when it travels in the opposite direction. This new technique to isolate light signals on a silicon chip, solves a longstanding problem in engineering photonic chips. [Caltech Press Release]

Wind-turbine Placement Produces Tenfold Power Increase

07-13-11

Field tests of John O. Dabiri, Professor of Aeronautics and Bioengineering, and colleagues' vertical-axis wind turbines have shown that the power output of wind farms can be increased by an order of magnitude—at least tenfold— by optimizing the placement of turbines on a given plot of land. "Dabiri's bioinspired engineering research is challenging the status quo in wind-energy technology," says Ares Rosakis, Division Chair and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. "This exemplifies how Caltech engineers' innovative approaches are tackling our society's greatest problems." [Caltech Press Release] [Videos of Turbines]
