Surprising phenomenon may lead to greater sensitivity in image sensor devices Engineers may soon be singing, "I'm going to wash that gray right out of my nanowires," thanks to a colorful discovery by a team of researchers from Harvard University and Zena Technologies. In contrast to the somber gray hue of silicon wafers, Kenneth B. Crozier and colleagues demonstrated that individual, vertical silicon nanowires can shine in all colors of the spectrum. The vibrant display, dependent on the...

Focusing on interdisciplinary research is now leading to breakthroughs in bio nanotechnology research. A new method for drug development has become a reality. Four years ago, the biologist Karen Martinez almost didn't believe in the research project herself when she started with her team working on it, but now it has been proven. Together with colleagues at the Nano-Science Center, her team has been able to combine nanoscale materials and technologies that are traditionally used for...

After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements "” a finger pinch now en route to a pulse beat in the future "” to generate electricity. Speaking here today at the 241st National Meeting & Exposition of the American Chemical Society, they described boosting the device's power output by thousands times and its voltage by 150 times to finally move it out of the...

New insights into why and how nanowires take the form they do will have profound implications for the development of future electronic components. PhD student Peter Krogstrup from the Nano-Science Center at the University of Copenhagen is behind the sensational new theoretical model, which is developed in collaboration with researchers from CINAM-CNRS in Marseille. One of the most important components in future electronic devices will likely be based on nanocrystals, which are smaller than...

A controversial idea that sense of smell can be explained by quantum physics is gaining traction in the science world, according to researchers. Researchers, reporting at the American Physical Society meeting in Dallas, say the key to proving how such a theory would work revolves around tiny packets of energy -- or quanta -- lost by electrons. The scientists performed experiments using tiny wires and showed that as electrons move on proteins within the nose, odor molecules could absorb...

Device may help process information and measure motion at quantum scale Physicists at the National Institute of Standards and Technology (NIST) have demonstrated an electromechanical circuit in which microwaves communicate with a vibrating mechanical component 1,000 times more vigorously than ever achieved before in similar experiments. The microscopic apparatus is a new tool for processing information and potentially could control the motion of a relatively large object at the smallest...

Researchers at North Carolina State University have developed a cheap and easy method for assembling nanowires, controlling their alignment and density. The researchers hope the findings will foster additional research into a range of device applications using nanowires, from nanoelectronics to nanosensors, especially on unconventional substrates such as rubber, plastic and paper. "Alignment is a critical first step for developing devices that use nanowires," says Dr. Yong Zhu, an assistant...

An article by Stevens Institute of Technology researchers featured as the cover page of Applied Physics Letters Volume 98, Issue 7 represents a step forward in techniques for the arrangement of nanowires. Professors Dr. Chang-Hwan Choi and Dr. Eui-Hyeok (EH) Yang, and graduate students Wei Xu, Rajesh Leeladhar, and Yao-Tsan Tsai, focused on nanowires, structures that are mere nanometers in diameter but have enormous potential in nanotechnology to create tiny circuits that would make possible...

Gallium nitride (GaN) and zinc oxide (ZnO) are among the most technologically relevant semiconducting materials. Gallium nitride is ubiquitous today in optoelectronic elements such as blue lasers (hence the blue-ray disc) and light-emitting-diodes (LEDs); zinc oxide also finds many uses in optoelectronics and sensors. In the past few years, though, nanostructures made of these materials have shown a plethora of potential functionalities, ranging from single-nanowire lasers and LEDs to more...
