Journal ArticleDOI
Electrospun polyacrylonitrile nanocomposite fibers reinforced with Fe3O4 nanoparticles: Fabrication and property analysis
Di Zhang,Amar B. Karki,Dan Rutman,David P. Young,Andrew Wang,David L. Cocke,Thomas H. Ho,Zhanhu Guo +7 more
TL;DR: In this paper, a uniform, bead-free fiber production process is developed by optimizing electrospinning conditions: polymer concentration, applied electric voltage, feedrate, and distance between needle tip to collector.
Journal ArticleDOI
Carbon-stabilized iron nanoparticles for environmental remediation
TL;DR: Ferromagnetic carbon-coated Fe nanoparticles fabricated at a mild temperature demonstrate a strong ability to effectively remove more than 95 wt% of Cr(VI) in waste water via carbon shell physical adsorption, which is much higher than the commercially available Fe NPs.
Journal ArticleDOI
Effects of iron oxide nanoparticles on polyvinyl alcohol: interfacial layer and bulk nanocomposites thin film
Zhanhu Guo,Di Zhang,Suying Wei,Zhe Wang,Amar B. Karki,Yuehao Li,Paul Bernazzani,David P. Young,Jewel A. Gomes,David L. Cocke,Thomas C. Ho +10 more
TL;DR: In this paper, the presence of polyvinyl alcohol (PVA) has been found to increase the cross-linkage of the bulk PVA matrices, resulting in a higher melting temperature and an enhanced thermal stability of the polymer matrix.
Journal ArticleDOI
Understanding and modeling alternating tangential flow filtration for perfusion cell culture.
William J. Kelly,Jennifer Scully,Di Zhang,Gang Feng,Mathew Lavengood,Jason Condon,John Knighton,Ravinder Bhatia +7 more
TL;DR: The experimental results indicate, in accordance with D'Arcy's law, that the average resistance to permeate flow (across a cycle of operation) increases as biological material deposits on the membrane.
Journal ArticleDOI
Magnetic and Magnetoresistance Behaviors of Solvent Extracted Particulate Iron/ Polyacrylonitrile Nanocomposites
TL;DR: In this article, the magnetic properties, electrical conductivity, and magnetic field dependent resistivity of heat-treated nanocomposites with different particle loadings are carried out in a physical properties measurement system by Quantum Design and by a standard four probe method.
