COVER OF THE YEAR

NSF CAREER AWARD

The research of Dr. Lei Zhai’s group at the NanoScience Technology Center has been featured as the 2009 Cover of the Year for the Macromolecular journal by Wiley Interscience, a ZRUOG ZLGH SXEOLVKHU RI HOLWH VFLHQWLÀF journals. In their paper published in Macromolecuar Rapid Communications (MRC, 2009, 30, 1837) Dr. Zhai and his postdoctoral fellow, Dr. Jianhua Liu, reported a non-invasive bottom-up approach that provides intriguing carbon nanotube based composites for energy conversion and storage devices and nanoscale electronics. Their eye-catching cover was selected from the front and back (a total of 109) covers within the six journals of the Macromolecular journal family in 2009.

RESEARCH INCENTIVE AWARD 2010 Research Incentive Award (RIA) award winners Dr. Saiful Khondaker and Dr. Jiyu Fang Dr. Khondaker (pictured left) is looking at electron transport measurements from a carbon nanotube device. His group studies transport properties of nanoelectronic devices consisting of carbon nanotubes, graphene and organic polymers. Dr. Jiyu Fang (pictured right) developed the application of Atomic Force Microscope indentation in studying nanomechanics of self-assembled lipid nanotubes.

Masahiro Ishigami, a joint appointment at NSTC and Department of Physics, has won the prestigious NSF Career Award in 2009, titled “Intrinsic Transport Properties of Graphene: Approaching the Elusive Ground State on Crystalline Substrates.â€? Graphene, a single layer of graphite, possesses unique electronic properties important for both fundamental and applied nanoscale materials physics research. Charge carriers in graphene behave much like light. This unusual property of intrinsic disorder-free graphene can be exploited to explore the consequences of relativistic Quantum Electrodynamics on a chip, making graphene important for increasing our understanding of fundamental physics. The utility of graphene for electronic applications is demonstrated by the observed UHVSRQVH RI WKH FKDUJH FDUULHUV WR DQ DSSOLHG HOHFWULF Ă€HOG WKH Ă€HOG HIIHFW Yet, because graphene is composed of only surface atoms, its intrinsic properties are sensitive to adsorbates and substrate-induced disorder. Adsorbate-induced disorder can now be eliminated, but so far substrate-induced disorder has not been controlled. Thus, the graphene remain unknown. This Faculty Early Career Award supports projects seeking to uncover the intrinsic properties of graphene and pave a way for the exploration of Quantum Electrodynamics by utilizing crystalline substrates. Such substrates are expected to eliminate substrate-induced disorder, and create “perfectâ€? graphene. The studies will also elucidate the intrinsic limitation of graphene-based devices. Thus, they have the potential to have a broad impact on electronic applications of graphene.

She recently received a Florida Department of Health Bankhead-Coley Foundation Bridge grant. She has also been a Co-PI in several other federal and internal grants. She supervised and graduated four Ph.D. and three M.Sc. students in the past several years. She has so far published 65 papers in peer-reviewed journals. She is also an associate editor for an Elsevier journal - Colloids and Surfaces B: Biointerfaces. While at NDSU, Dr. Huo mainly taught graduate level courses. Since Dr. Huo joined UCF, she has focused her efforts in teaching the undergraduate level courses Organic Chemistry I and II for the Department of Chemistry. Organic Chemistry is one of the most challenging topics for the undergraduate students. Dr. Huo very much enjoyed her teaching experiences from these courses by helping the students to overcome their fear in learning organic chemistry. Dr. Huo’s research has been related to two areas: polymer nanocomposite materials and gold nanoparticles. In WKH ÀUVW IHZ \HDUV RI KHU IDFXOW\ FDUHHU KHU ZRUN ZDV IRcused on polymer nanocomposites. Her group developed gold nanoparticles and carbon nanotube-based polymer composite materials for various application studies.

In collaboration with colleagues Dr. Lei Zhai and Dr. Saiful Khondaker at NSTC, they developed a new method for carbon nanotube dispersion using conjugated conducting polymers. This work was also published in Advanced Materials. In recent years, Dr. Huo’s research has been more focused on gold nanoparticles and their applications for biomolecular detection and analysis.
