Disease Diagnosis at the Touch of a Button

02-25-13

Axel Scherer, Bernard Neches Professor of Electrical Engineering, Applied Physics and Physics, and colleagues have built a new version of a polymerase chain reaction (PCR) device, which generates many copies of a pathogenic nucleic acid, allowing the infection to be detected. The device is the result of nearly 10 years of research at Caltech. In 2004, Scherer, a leader in the field of microfluidics, and George Maltezos were investigating how to manipulate biological fluids on a chip. While this was an interesting engineering problem, Maltezos began to wonder how he could apply the microfluidic techniques that he was perfecting to real-world problems. Then the H5N1 bird flu pandemic erupted in Asia, and the team had their real-world problem. [Caltech Release]

EAS Division Welcomes New Deputy Chair

02-08-13

Peter Schröder, Professor of Computer Science and Applied and Computational Mathematics, is the new Deputy Chair of the Division of Engineering and Applied Science. "I look forward to working with Peter over the next several years as we continue with our quest to remain a unique collaborative community of isolated singularities that sets a compelling model as a research and teaching institution," says Chair Ares Rosakis.

Creating New Quantum Building Blocks

02-07-13

Andrei Faraon, Assistant Professor of Applied Physics and Materials Science, and colleagues have laid the groundwork for an on-chip optical quantum network by showing that defects in diamond can be used as quantum building blocks that interact with one another via photons. "Right now we only have one nitrogen-vacancy center that's emitting photons, but in the future we envision creating multiple nitrogen-vacancy centers that emit photons on the same chip," Faraon says.

Diving Into the Unknown: An Interview with Andrei Faraon

11-13-12

Assistant Professor and alumnus Andrei Faraon builds devices that are based on the fundamentals of light–matter interaction. He is trying to manipulate single quantum systems in solids—systems like single atoms or single quantum dots—using light. Light is great for this purpose because it allows him to address these systems without destroying their fragile quantum states, and because it can easily interconnect quantum systems over large distances.

Clean-Energy Research Accelerates

10-22-12

Caltech clean-energy research is accelerating thanks to the renovation of the Earle M. Jorgensen Laboratory. Transformed into a cutting-edge facility for energy science, the lab unites two powerhouse programs: the Resnick Sustainability Institute and the Joint Center for Artificial Photosynthesis (JCAP). "Our researchers are working with Caltech's chemists and chemical engineers to challenge the status quo and translate scientific discovery into clean-energy innovations that will directly benefit society for generations to come," says Chair Ares Rosakis.

Developing the Next Generation of Microsensors

10-19-12

Oskar J. Painter, Professor of Applied Physics; Executive Officer for Applied Physics and Materials Science; and Co-Director, Kavli Nanoscience Institute, and colleagues have engineered a microscale optical accelerometer. In addition to transforming consumer electronics, such sensors could help with oil and gas exploration deep within the earth, could improve the stabilization systems of fighter jets, and could even be used in some biomedical applications where more traditional sensors cannot operate. "Professor Painter's research in this area nicely illustrates how the Engineering and Applied Science faculty at Caltech are working at the edges of fundamental science to invent the technologies of the future," says Chair Ares Rosakis.

Professor Greer Receives Breakthrough Award from Popular Mechanics magazine

10-01-12

Julia R. Greer, Assistant Professor of Materials Science and Mechanics, is receiving a 2012 Breakthrough Award from Popular Mechanics magazine as part of the team that engineered the world's lightest solid material. "I am delighted that Professor Greer is being honored with this award," says Ares Rosakis, chair of the Division of Engineering and Applied Science (EAS) at Caltech. "She is a great example of how we in EAS are working at the edges of fundamental science to invent the technologies of the future." [Caltech Release]

Weighing Molecules One at a Time

08-27-12

Michael L. Roukes, Robert M. Abbey Professor of Physics, Applied Physics, and Bioengineering as well as Co-Director of the Kavli Nanoscience Institute, and colleagues have created the first-ever mechanical device that measures the mass of a single molecule. The device—which is only a couple millionths of a meter in size—consists of a tiny, vibrating bridge-like structure. When a particle or molecule lands on the bridge, its mass changes the oscillating frequency in a way that reveals how much the particle weighs. [Caltech Press Release]
