single-walled carbon nanotubes News
Nanotube-Based Solar Cells Make More of the Sun
Dec 12, 2014 — They’re cheaper, lighter, flexible and easy to dispose – it’s little wonder that carbon nanotubes are grabbing the attention of solar cell specialists in Europe and beyond. Since they were first discovered in 1991, carbon nanotubes (CNTs) – and single-walled carbon nanotubes (SWCNTs) in particular – have attracted great attention, thanks to their unique optical properties and versatility. Low-temperature processing means that CNT-based solar cells are
Carbon Nanotubes Get Better as Solar Cells
EVANSTON, Ill., Sept. 4, 2014 — A new type of carbon nanotube has taken a “big jump” beyond its predecessors in solar cell applications. Single-walled carbon nanotubes (SWCNT), developed by a team from Northwestern University’s McCormick School of Engineering,...
Carbon Nanotubes Create More Efficient IR Detector
BEIJING, May 24, 2012 — Carbon nanotubes seem to be useful for just about every conceivable application. Their newest purpose is to create highly sensitive uncooled photovoltaic infrared detectors that can be used for industrial, manufacturing, communications and military...
‘Sonic Boomlets’ Used to Cut Nanotubes
PROVIDENCE, R.I., Dec. 23, 2010 — For the first time researchers have documented how single-walled carbon nanotubes are cut, a finding that could lead to producing more precise, higher-quality nanotubes. According to the researchers at Brown University and in Korea, such...
Brighter Nanotubes Unveiled
STORRS, Conn., March 9, 2009 – Chemists have found a way to increase the luminescence efficiency of single-walled carbon nanotubes, a discovery that could have significance in medical imaging, homeland security, and biological sensors, among other applications.
Defining the Relationship Between Nanotube Length
and Optical Response
Oct 1, 2007 — Single-walled carbon nanotubes have numerous optical properties of interest to physicists and electronics engineers. However, whereas these nanometer-scale constructs have been well-studied regarding the influence of diameter and chirality on their...
Nanotube Sheet Employed as OLED Electrode
Jul 1, 2006 — Organic LEDs (OLEDs) incorporating an anode made from a thin sheet of single-walled carbon nanotubes display performance similar to that of devices that employ indium tin oxide, report investigators in Montreal. The finding offers device designers...
Near-Field Raman Offers 25-nm Resolution
Apr 1, 2003 — Researchers at the University of Rochester in New York, Portland State University in Oregon and Harvard University in Cambridge, Mass., have reported a spatial resolution of 25 nm in their study of the near-field Raman imaging of single-walled...
Spectra Identify Nanotube Species
Jan 1, 2003 — Chemists at Rice University in Houston have reported that spectrofluorometry is an effective tool in identifying various species of single-walled carbon nanotubes. They suggest that the technique may be used to guide the selective production of...
