Criterion For An Oscillatory Charged Jet During The Bubble Spinning Process, Ji-Huan He, H.Y. Kong

The oscillatory diameter of the charged jet during the bubble electrospinning results in beads on the obtained nanofibers. We demonstrate that the applied voltage and the initial flow rate of the jet are the crucial parameters that are necessary to control morphology of the nanofibers. We also find that there is a criterion for production of smooth nanofibers without beads. The theory developed in this paper can be extended to the classical electrospinning and the blown bubble-spinning.

Connecting Research On Social Issues In Nanotechnology: The Center For Nanotechnology In Society At Arizona State University, Jan Youtie, Philip Shapira

Philip Shapira

Central to the emergence of new research topics is the creation of a research network. This paper looks at the creation of a network of researchers of social issues in nanotechnology and the role of the Center for Nanotechnology in Society at Arizona State University (CNS-ASU) in the creation of this network. While there has been US investment in societal research on nanotechnology, a debate exists about the extent to which a research community has been created through these investments. This paper uses three approaches to examine the extent to which CNS-ASU is associated with the development of a research ...
