Research on "Photodetectors: Fullerene Photodetectors with a Linear Dynamic Range of 90 dB Enabled by a Cross-Linkable Buffer Layer" is the cover feature for Advanced Optical Materials' April 2013 edition. UNL MME Assistant Professor Jinsong Huang and colleagues report a low-noise, high-sensitivity, fullerene-based organic photo detector with a wide dynamic range. The enhanced dynamic range is achieved via an inserted cross-linkable buffer layer. The advance in light responsiveness is among the highest reported for any organic photodetector, and larger than those of inorganic photodetectors such as GaN and InGaAs.
Carl Nelson, associate professor of Mechanical and Materials Engineering, collaborated for three years with researchers at Madonna Rehabilitation Hospital in Lincoln to develop the Intelligently Controlled Assistive Rehabilitation Elliptical Training System, or ICARE. It won the da Vinci award in the Recreation and Leisure category at an April 11 ceremony in Dearborn, Mich.
When most tough fibres are stretched to make them thinner, they become brittle. But a group led by Yuris Dzenis has shown that this is not always the case. The March 21, 2013 issue of Nature reported that Dzenis' team made polyacrylonitrile fibres using a technique called electrospinning. As their diameters narrowed to below 250 nanometres, the fibres became tougher and so were less prone to fracture, but did not lose their strength. Nanofibres were up to 10-fold tougher and stronger than the best commercial fibres. Dzenis suggests that the toughening is possible because the nanofibres are less crystalline than larger fibres. He thinks that the fibres could be used in load-bearing aerospace structures and bulletproof materials. MORE...
