1st Annual Graduate Student Elevator Pitch Competition
Graduate students from all Rice schools participated in the first campus-wide Elevator Pitch competition on the importance of their research and its importance in 90 seconds. The competition measured the participant's ability to engage their audience intellectually. Mohammed Adnan, CHBE, won First Place with his presentation on "Continuous fibers of Boron Nitride
Nanotubes" for which he received $500. See the video here.
Rice University's latest nanotechnology breakthrough was more than ten years in the making. Scientists have created the
first pure carbon nanotube fibers that combine many of the best features of
highly conductive metal wires, strong carbon fibers and pliable textile thread.
In a paper this week in Science, researchers from Rice University, the Dutch
firm Teijin Aramid, the U.S. Air Force and Israel's Technion Institute describe
an industrially scalable process for making the threadlike fibers, which
outperform commercially available products in a number of ways. Dr. Natnael Behabtu (2012 Rice Alumni) et al. publishes paper on "Strong, Light,
Multifunctional Fibers of Carbon Nanotubes with Ultrahigh Conductivity". This publication has received national and international media coverage. Dr. Behabtu is a Research Engineer with DuPont in Wilmington DE. See full story here and see published paper here as a pdf.
Tubular films show promise for touchscreens
The Pasquali lab has found that slides dipped into a solution of pure nanotubes in chlorosulfonic acid left an even coat of nanotubes that, after processing, became nearly transparent films of electrically conductive carbon nanotubes. This is a goal sought by researchers around the world and could hold the key for flexible electronic displays and touchscreens. The paper is published this month in the American Chemical Society journal ACS Nano. Lead author and graduate student Francesca Mirri and her colleagues produced the films by combining single- or double-walled carbon nanotubes with CSA in various concentrations. The article was co-authored by former postdoctoral researcher Anson Ma, now an assistant professor at the University of Connecticut; postdoctoral researchers Shannon Eichmann and Tienyi Theresa Hsu; former graduate student Natnael Behaptu, now a researcher at DuPont; graduate student Colin Young; and senior undergraduate Dmitri Tsentalovich, all from Rice.

Technion Institute of Technology (Israel) and Rice University image nanotubes filled with acid
Chemical Communications published “Direct Imaging of carbon nanotubes spontaneously filled with solvent” January 2011.In collaboration with researchers from the Technion in Haifa, Israel, the Pasquali group used cryo-TEM imaging to show that dispersed multi-walled carbon nanotubes (MWNTs) can be filled with chlorosulfonic acid. The striking images even show internal caps inside the MWNTs where one side of the cap is filled and the other is not. These findings have extensive implications for acid-processed nanotube materials. This article was authored by Micah Green, Colin Young, Nicholas Parra-Vasquez, Mainak Majumder, Varun Juloori, Natnael Behabtu, Cary Pint, Judith Schmidt, Ellina Kesselman, Robert Hauge, Yachin Cohen, Ishi Talmon, and Matteo Pasquali.

Nature Physics published "Formation of beads-on-a-string structures during break-up of viscoelastic filaments" June 2010
Researchers from Purdue, Rice, and MIT discover the break-up of viscoelastic filaments is pervasive in both nature and technology which is published in the June issue of Nature Physics.This work was supported by the National Science Foundation Engineering Research Center for Structured Organic Particulate Systems (NSF ERC-SOPS)(EEC-0540855) at Rutgers, Purdue, NJIT and UPRM. G.H.M., acknowledges support from the Nanoscale Interdisciplinary Reasearch Thrust on `Directed Self-assembly of Suspended Polymer Fibers' (NSF-DMS0506941.If a filament is formed by placing a drop of saliva between a thumb and forefinger and is stretched, the filament’s morphology close to break-up corresponds to beads of several sizes interconnected by slender threads. Although there is general agreement that formation of such beads-on-a-string (BOAS) structures occurs only for viscoelastic fluids, the underlying physics remains unclear and controversial. The physics leading to the formation of BOAS structures is probed by numerical simulation. Computations reveal that viscoelasticity alone does not give rise to a small, satellite bead between two much larger main beads but that inertia is required for its formation. Viscoelasticity, however, enhances the growth of the bead and delays pinch-off, which leads to a relatively long-lived beaded structure. We also show for the first time theoretically that yet smaller, sub-satellite beads can also form as seen in experiments.

Technology Review: This Year in Materials
New materials harnessed hamster power, and researchers made carbon nanotubes practical.For years now, people have been talking up carbon nanotubes and their potential to be used for far-out applications including strong space-elevator cables, robust electrical transmission lines, and high performance nanotube computers.Researchers at Rice University refined methods for spinning acid solutions of carbon nanotubes into fibers hundreds of meters long ("Making Carbon Nanotubes into Long Fibers"). Their process, which could be used industrially (it's similar to how Kevlar is made), is the culmination of eight years of work begun by the late Richard Smalley, who shared the Nobel Prize in chemistry in 1996 for the discovery of carbon nanomaterials ("Wires of Wonder"). In order to make electrical transmission lines, researchers still need to perfect a process for growing pure batches of metallic nanotubes. Today they come out mixed with semiconducting tubes, and the two must be separated. Still, the Rice demonstration of making nanotubes into large structures is a major accomplishment.
