University of Illinois researcher Xiuling Li, associate professor in electrical and computer engineering, along with Kyoung Jin Choi, associate professor at the Ulsan National Institute of Science and Technology, South Korea, have led a team that successfully demonstrated uniform wafer-scale III-V nanowire growth on silicon. The research team developed a novel method to epitaxially grow structurally and compositionally homogeneous and spatially and spectrally uniform ternary nanowires on silicon at wafer-scale using metalorganic chemical vapor deposition (MOCVD). Previously, a common method for creating nanowires was using Au-assisted Vapor-Liquid-Solid synthesis, but that can cause significant degradation of the quality of the semiconductor nanowires. The team expects their effort to help further research in renewable energy, as it could lead to "high-efficiency and low-cost large-scale solar cells," according to Prof. Choi. This research was published in ACS Nano, DOI: 10.1021/nn4014774.
By confining various liquids inside a hollow microfluidic optomechanical resonator, researchers at Illinois built the first-ever bridge between optomechanics and microfluidics. The team is led by Gaurav Bahl, assistant professor in the Department of Mechanical Science and Engineering. The team's work, which was published in Nature Communications, has the potential to enable strongly localized, high-sensitivity, optomechanical interaction with chemical and biological samples.
Two Illinois professors, Yuanhui Zhang and Lance Schideman, have developed a way to create a new biofuel from swine manure. The two are professors in Agricultural and Biological Engineering, and Zhang also is affiliated with the Department of Bioengineering. The process they've developed not only results in a form of crude oil that could be used as fuel, it also employs biomass to clean the resulting wastewater. A possible application of the technology could include mixing the team's biofuel with existing fuel. News of the biofuel development recently appeared in domesticfuel.com.
A new form of microbattery developed at Illinois drastically reduces limitations previously inherent in microelectronics -- the tradeoff of high power for low energy or vice versa. The revolutionary 3-D design of the Illinois team's battery allows for high performance in both power and energy. Results of the research were published in Nature Communications April 16. The Illinois team is led by Prof. William King includes student James Pikul, both in Mechanical Science and Engineering.
The R. W. Wood Prize is given for an outstanding discovery, scientific or technological achievement or invention. Milton Feng received this recognition for contributions to the invention and realization of the transistor laser, delivering simultaneously both an electrical signal and a coherent laser output and providing the basis for a revolutionary new higher speed electronic-photonic integrated circuit. Established by OSA in 1975 to honor the many contributions that R.W. Wood made to optics, this award recognizes an outstanding discovery, scientific or technical achievement, or invention in the field of optics. The accomplishment for which the prize is given is measured chiefly by its impact on the field of optics generally, and therefore the contribution is one that opens a new era of research or significantly expands an established one. It is endowed by the Xerox Corporation.
