Discovery of 'doping' mechanism in semiconductor nanocrystals
Novel electronic devices based upon nanotechnology may soon be realized due to a new understanding of how impurities, or 'dopants,' can be intentionally incorporated into semiconductor nanocrystals. View More (2005-07-11)
Gold Solution for Enhancing Nanocrystal Electrical Conductance
In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have reported a technique by which the electrical conductivity of nanorod crystals of the semiconductor...

Growth Spurts: Berkeley Lab Researchers Record First Real-Time Direct Observations of Nanocrystal Growth in Solution
The veil is being lifted from the once unseen world of molecular activity. Not so long ago only the final products were visible and scientists were forced to gauge the processes behind those products by ensemble averages of many molecules. View More (2009-08-10)
Designer nanomaterials on-demand: Berkeley Scientists Report Universal Method for Creating Nanoscale Composites
Composites are combinations of materials that produce properties inaccessible in any one material. A classic example of a composite is fiberglass - plastic fibers woven with glass to add strength to hockey sticks or the hull of a boat. View More (2010-03-22)
Conducting energy on a nano scale
Modern electronics as we know them, from televisions to computers, depend on conducting materials that can control electronic properties. View More (2011-07-15)
Nanocrystal transformers
While a movie about giant robots that undergo structural transformations is breaking box office records this summer, a scientific study about structural transformations within single nanocrystals is breaking new ground for the design of novel materials that will serve next-generation energy storage batteries and solar energy harvesting devices.

New imaging technique reveals the atomic structure of nanocrystals
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). View More (2009-02-19)
Gold-tipped nanocrystals developed by Hebrew University researchers
"Nanodumbells" - gold-tipped nanocrystals which can be used as highly-efficient building blocks for devices in the emerging nanotechnology revolution - have been developed by researchers at the Hebrew University of Jerusalem. The technology, developed by a research group headed by Prof. Uri Banin of the Department of Physical Chemistry and the Center for Nanoscience and Nanotechnology... View More (2004-06-17)
New paper offers insights into 'blinking' phenomena
A new paper by a team of researchers led by University of Notre Dame physicist Bolizsár Jankó provides an overview of research into one of the few remaining unsolved problems of quantum mechanics. View More (2008-07-02)
Penn Researchers Make Flexible, Low-voltage Circuits Using Nanocrystals
Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications. In a world where electronics are becoming more pervasive, flexibility is a highly desirable trait, but finding materials with the right mix of performance and manufacturing cost remains a challenge.

Nanoparticles show promise as inexpensive, durable and effective scintillators
A team of industrial and university researchers has shown that nanoparticles with sizes smaller than 10 nanometers - approximately the width of a cell membrane - can be successfully incorporated into scintillation devices capable of detecting and measuring a wide energy range of X-rays and gamma rays emitted by nuclear materials.

Research highlights potential for improved solar cells
A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication-when a photon creates multiple electrons-is a real phenomenon in tiny semiconductor crystals and not a false observation born of extraneous effects that mimic carrier multiplication. The research, explained in a recent issue of Accounts of Chemical Research, shows the possibility of solar cells that create... View More (2009-02-11)
Glorious gadolinium gives flash memory a future
Future flash memory could be faster and store more data without changing its basic design by using a clever nanocrystal material proposed by scientists at Taiwan's Chang Gung University, who describe a new logical element made with the rare earth material gadolinium in the journal APPLIED PHYSICS LETTERS, which is published by the American Institute of Physics.

Researchers develop a path to liquid solar cells that can be printed onto surfaces
Scientists at USC have developed a potential pathway to cheap, stable solar cells made from nanocrystals so small they can exist as a liquid ink and be painted or printed onto clear surfaces. View More (2012-04-26)
A Dash of Disorder Yields a Very Efficient Photocatalyst
A little disorder goes a long way, especially when it comes to harnessing the sun's energy. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) jumbled the atomic structure of the surface layer of titanium dioxide nanocrystals, creating a catalyst that is both long lasting and more efficient than most materials in using the sun's energy to extract...
