Caltech Scientists Solve Decade-Long Mystery of Nanopillar Formations

Caltech scientists have uncovered the physical mechanism by which arrays of nanoscale pillars can be grown on polymer films with very high precision, in potentially limitless patterns. This nanofluidic process—described in a recent article in Physical Review Letters—could someday replace the conventional lithographic patterning techniques now used to build 3-D nano- and microscale structures for use in optical, photonic, and biofluidic devices.

Two International Leaders Receive Caltech Aerospace Award

Two distinguished aerospace leaders are the recipients of the 25th annual International von Kármán Wings Award. Receiving the honor this year are Abdul Kalam, the 11th president of India and distinguished professor at the Indian Institute of Technology, and Yannick d'Escatha, chairman and chief executive officer of the Centre National d'Etudes Spatiales (CNES).

Caltech and IBM Scientists Use Self-Assembled DNA Scaffolding to Build Tiny Circuit Boards

Scientists at the Caltech and IBM's Almaden Research Center have developed a new technique to orient and position self-assembled DNA shapes and patterns--or "DNA origami"--on surfaces that are compatible with today's semiconductor manufacturing equipment. These precisely positioned DNA nanostructures, each no more than one one-thousandth the width of a human hair, can serve as scaffolds or miniature circuit boards for the precise assembly of computer-chip components.

Shang-Li and Betty Huang create endowment to support Caltech graduate students

Caltech alumnus Shang-Li “S.L.” Huang and his wife have pledged $1 million to Caltech to endow the Shang-Li and Betty Huang Endowed Graduate Fellowship Fund in Mechanical Engineering.

Caltech Researchers Link Tiny Sea Creatures to Large-scale Ocean Mixing

Using a combination of theoretical modeling, energy calculations, and field observations, researchers from the California Institute of Technology (Caltech) have for the first time described a mechanism that explains how some of the ocean's tiniest swimming animals can have a huge impact on large-scale ocean mixing.

Hans W. Liepmann, 94

Hans Wolfgang Liepmann, a pioneering researcher and passionate educator in fluid mechanics, passed away at the age of 94. Widely honored for his contributions to aeronautics, Liepmann came to Caltech in 1939 and was the third director of Caltech's Graduate Aeronautical Laboratories (GALCIT), from 1972 to1985.

Kent and Joyce Kresa Endow Professorial Chair at Caltech

Kent and Joyce Kresa have pledged $2 million to endow the Joyce and Kent Kresa Professorship in Engineering and Applied Science at Caltech.

Caltech Scientists Use High-Pressure "Alchemy" to Create Nonexpanding Metals

By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, scientists at the California Institute of Technology (Caltech) have created a material that does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition. 

Caltech Announces Initiative for a New $90 Million Sustainability Institute

California Institute of Technology (Caltech) president Jean-Lou Chameau began today's commencement ceremony by announcing $30 million in gifts as the first phase of a proposed $90 million initiative for a new institute. The funds will go towards the creation of the Resnick Sustainability Institute at Caltech.

Caltech Scientists Create Nanoscale Zipper Cavity that Responds to Single Photons of Light

Physicists at Caltech have developed a nanoscale device that can be used for force detection, optical communication, and more. The device exploits the mechanical properties of light to create an optomechanical cavity in which interactions between light and motion are greatly strengthened and enhanced. These interactions, notes Oskar Painter, associate professor of applied physics at Caltech, and the principal investigator on the research, are the largest demonstrated to date.
