Can you see me now? Flexible photodetectors could help sharpen photos
Distorted cell-phone photos and big, clunky telephoto lenses could be things of the past. University of Wisconsin-Madison Electrical and Computer Engineering Associate Professor Zhenqiang (Jack) Ma and colleagues have developed a flexible light-sensitive material that could revolutionize photography and other imaging technologies. view more (2009-01-14)
Zinc oxide gives green shine to new photoconductors
Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manufacture of very powerful photodetectors needs to be improved before they can qualify for solid green status. view more (2009-03-19)
Fishing biomolecules
Rapid substance identification is an indispensable tool for laboratories and process monitoring. An optical biochip developed as part of the EU-funded project BIOMIC is capable of simultaneously measuring the concentrations of eight different proteins or DNA fragments. view more (2004-03-18)
Harvard scientists bend nanowires into 2-D and 3-D structures
Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. view more (2009-10-22)
Paint-on semiconductor outperforms chips
Researchers at the University of Toronto have created a semiconductor device that outperforms today's conventional chips — and they made it simply by painting a liquid onto a piece of glass. view more (2006-07-13)
New Superlattice Structure Enables High Performance Infrared Imaging
Scientists at the Center for Quantum Devices (CQD) in the McCormick School of Engineering at Northwestern University have demonstrated for the first time a high-performance infrared imager, based on a Type II superlattice, which looks at wavelengths 20 times longer than visible light. view more (2008-05-28)
New technology could lead to camera based on human eye
Digital cameras have transformed the world of photography. Now new technology inspired by the human eye could push the photographic image forward even more by producing improved images with a wider field of view. view more (2008-08-07)
Nano-sized Electronic Circuit Promises Bright View of Early Universe
A newly developed nano-sized electronic device is an important step toward helping astronomers see invisible light dating from the creation of the universe. This invisible light makes up 98% of the light emitted since the "big bang," and may provide insights into the earliest stages of star and galaxy formation almost 14 billion years... view more...
