Buckypaper and nanocrystalline cellulose; two different paths to the same ends?

Leave a reply

Buckypaper interests me largely because of its name (along with Buckyballs and Buckytubes [usually called carbon nanotubes]). I believe the names are derived from Buckminsterfullerenes a form of carbon engineered (it can be found in nature) in the labs at Rice University. From the Wikipedia essay on Buckminsterfullerenes,

Buckminsterfullerene is a spherical fullerene molecule with the formula C60. It was first prepared in 1985 by Harold Kroto, James Heath, Sean O’Brien, Robert Curl and Richard Smalley at Rice University.  Kroto, Curl, and Smalley were awarded the 1996 Nobel Prize in Chemistry for their roles in the discovery of buckminsterfullerene and the related class of molecules, the fullerenes. The name is an homage to Richard Buckminster Fuller, whose geodesic domes it resembles. Buckminsterfullerene was the first fullerene molecule discovered and it is also the most common in terms of natural occurrence, as it can be found in small quantities in soot.

Buckypaper is a main focus at the High Performance Materials Institute at the Florida State University, which has just *released a promotional video (according to the Oct. 3, 2011 news item on Nanowerk). Here’s the video,

It reminds me a little of the video for Nokia’s Morph concept, which was released a few years back. I haven’t heard any substantive news about that project although there are the occasional updates. For example, the Morph was originally described it as a phone and then they changed it to the Morph concept. I’d love to see a prototype one of these days. (There’s more about the Morph and its incarnations in my Sept. 29, 2010 posting.)

The descriptions for applications using Buckypaper reminded me of nanocrystalline cellulose as I’ve seen some of the same claims made for that substance. I’m hoping to hear about the new plant in Windsor, Québec which is supposed to be opening this fall. From the ArboraNano new projects page,

Currently, Canada has an 18- to 24-month global lead in the commercial production of NCC as a 1 ton/day demonstration plant located in Windsor, Quebec enters the final phases of construction. Startup is planned for Fall 2011.

It’s good to see all these different research efforts and to reflect on the innovation being demonstrated.

Year of Nano at Rice University

I mentioned the Year of Nano 25th anniversary celebration of the buckminsterfullerene (also known as a C60 fullerene or bucky ball) at Rice University in a Feb. 8, 2010 posting (it’s towards the bottom) and wasn’t really expecting to hear more about it until the technical symposium in October 2010. Yesterday, the folks at Rice University sent out a news release that manages to herald both the Year of Nano and the 50th anniversary of the laser. From the news release (titled, From beams to bucky balls),

Twenty-five years after the laser beam came to be, a historic meeting took place at Rice University that led to the discovery of the buckminsterfullerene, the carbon 60 molecule for which two Rice scientists won the Nobel Prize.

Now that the buckyball is celebrating its own 25th anniversary, it’s worth noting that one wouldn’t have happened without the other.

During the Year of Nano, Rice will honor Nobel laureates Robert Curl and the late Richard Smalley, their research colleague and co-laureate, Sir Harold Kroto, then of the University of Sussex, and former graduate students James Heath and Sean O’Brien with a series of events culminating in an Oct. 11-13 symposium at Rice on nanotechnology’s past, present and future.

But Curl happily throws a share of the credit to another Rice professor, Frank Tittel, a laser pioneer whose work continues to break new ground in chemical sensing.

Fifty years ago this Sunday, on May 16, 1960, Hughes Research scientist Theodore Maiman fired off the first laser beam from a small ruby rod, a camera flashlamp and a power supply.

Not long after the news was reported in the New York Times, Tittel, now Rice’s J.S. Abercrombie Professor in Electrical and Computer Engineering, was asked by his new bosses at General Electric to recreate Maiman’s device. “That used brute force,” Tittel said of his first laser, later donated to the Franklin Institute Science Museum in Philadelphia. “Now we’re more sophisticated.”

Tittel joined Rice in 1967 and quickly built the first tunable laser in Texas, used in spectroscopy and sensing devices. He also formed collaborations with other professors, including Curl, who is now Rice’s University Professor Emeritus and Kenneth S. Pitzer-Schlumberger Professor Emeritus of Natural Sciences.

The laser attracted a lot of interest and was used to investigate a number of phenomena including Kroto’s chief interest in 1985, the “abundance of carbon molecules in interstellar clouds,”

…  The experiments in late 1985 showed an abundance of carbon 60, which set the scientists racing to figure out what such a molecule would look like. “We had this problem that this (carbon cluster) was a little strong, and it looked like there was something there,” Curl said, noting that the team pursued the interstellar question no further. “The discovery of the fullerenes drew all our attention.”

Smalley was the first to find the solution by assembling a paper model of hexagons and pentagons that turned out to be identical to a soccer ball. (In a webcast available here, Curl described how the team came up with the key to the solution over enchiladas at a Houston diner.)

The webcast with Curl is titled, How Astrophysical Interests Accidentally Led to Advances in Carbon Chemistry. I think what’s so fascinating is that Richard Smalley wasn’t that interested in Kroto’s question but it was that question that led to their great discovery. This story reminded me of a comment from Dr. J. Storrs Hall that I quoted in one of my recent posts (scroll down to find the passage), “As Dr. Hall aptly noted it’s not dispassionate calculations but ‘serendipity: the way science always works’.”
