Derek Peloquin and Nathan BehmThe Nanoscale Science Ph.D. Program at UNC charlotte would like to congratulate Derek Peloquin and Nathan Behm for getting their team project work published in a peer-reviewed journal. The advance copy of their article, “High-throughput microwave synthesis and characterization of NiO nanoplates for supercapacitor devices” is available online at the Springer’s Journal of Materials Science(DOI: 10.1007/s10853-012-6929-6). As Nathan remarks, “It’s cool to have a publication out of one semester work.”

NANO 8202 - Interdisciplinary TemaNathan Behm and Derek Peloquin joined the Nanoscale Science Ph.D. Program last year, in 2011. They were assigned to Dr. Poler’s group for their interdisciplinary team project in the following spring semester.                           

Hexagonal nickel oxide (NiO) nanoplate-based electrochemical supercapacitorsThe basic idea, as Nathan explains, in the beginning was to make a hybrid device, which combines the high power...

Andrew Greytak​Colloidal semiconductor nanocrystals – a type of quantum dot (QD) – are well-known as bright, highly photostable inorganic fluorophores that can be well-suited to imaging applications in biology. Additionally, the delocalized electronic states present in nanoscale semiconductors should offer distinctive ways to interact with and report on the biological environment. Such applications require good control of the interfacial chemistry of inorganic nanoparticles: in particular, to guide the formation of core/shell heterostructures to optimize brightness, and to introduce a surface coating that can enable the particles to function properly in the biological environment while limiting hydrodynamic size and avoiding quenching of the QD excited state. Significant progress has been made in identifying specific examples that comprise these features, especially for the case of metal chalcogenide semiconductors, but there remains only a limited understanding of the reaction mechanisms and thermodynamics associated with the elaboration of the surfaces of such particles with inorganic and organic layers. I will describe...
