Writing at the nanoscale
At the U.S. Department of Energy's Brookhaven National Laboratory, scientists have developed a new chemical "writing" technique that can create lines of "ink" only a few tens of nanometers, or billionths of a meter, in width. view more (2005-08-29)
Researchers peg magnetism as key driver of high-temperature superconductivity
When it comes to superconductivity, magnetic excitations may top good vibrations. view more (2006-07-06)
Argonne's Hard X-ray Nanoprobe provides new capability to study nanoscale materials
The Center for Nanoscale Materials' (CNM) newly operational Hard X-ray Nanoprobe at the U.S. Department of Energy's (DOE) Argonne National Laboratory is one of the world's most powerful x-ray microscopes. view more (2008-06-25)
Physicists describe a new mechanism for metallic magnetism
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists. view more (2005-08-26)
Rice scientists make breakthrough in single-molecule sensing
In a study that could lay the foundation for mass-produced single-molecule sensors, physicists and engineers at Rice University have demonstrated a means of simultaneously making optical and electronic measurements of the same molecule. view more (2008-02-07)
It's raining pentagons
This week's Nature Materials (09 March 2009) reveals how an international team of scientists led by researchers at the London Centre for Nanotechnology (LCN) at UCL have discovered a novel one dimensional ice chain structure built from pentagons that may prove to be a step toward the development of new materials which can be used to seed clouds... view more...

Nano propellers pump with proper chemistry
The ability to pump liquids at the cellular scale opens up exciting possibilities, such as precisely targeting medicines and regulating flow into and out of cells. But designing this molecular machinery has proven difficult. view more (2007-07-17)
Carnegie scientists fine-tuning methods for Stardust analysis
On Sunday, January 15, NASA's Stardust mission landed safely with the first solid comet fragments ever brought back to Earth. Members of the mission's Preliminary Examination Team, including several from the Carnegie Institution's Geophysical Laboratory and Department of Terrestrial Magnetism, are among the first to analyze these precious samples. view more (2006-03-23)
Tension in the nanoworld
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. view more (2009-01-26)
Magnetic nano-'shepherds' organize cells
The power of magnetism may address a major problem facing bioengineers as they try to create new tissue -- getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish that growth. view more (2009-04-01)
Stunt doubles: Ultracold atoms could replicate the electron 'jitterbug'
Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted. view more (2008-03-11)
Sol-gel inks produce complex shapes with nanoscale features
New sol-gel inks developed by researchers at the University of Illinois can be printed into patterns to produce three-dimensional structures of metal oxides with nanoscale features. view more (2007-10-12)
Magnetic nano-'shepherds' organize cells
The power of magnetism could be an enabling technology to address a major problem facing bioengineers as they try to create new tissue-getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish their growth. view more (2009-04-01)
Nanoscale study gives new insight into heat transfer in biological systems
One of the first things we learn in chemistry class is that solids conduct heat better than liquids. But a new study suggests that in nanoscale materials, this is not necessarily the case. view more (2005-10-21)
Nano-signals get a boost from magnetic spin waves
Researchers have figured out how nanoscale microwave transmitters gain greater signal power than the sum of their parts-a finding that will help in the design of nano-oscillator arrays for possible use as transmitters and receivers in cell phones, radar systems, or computer chips. view more (2006-09-01)
Transforming Nanowires Into Nano-Tools Using Cation Exchange Reactions
A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. view more (2009-10-26)
Bon MOT: Innovative atom trap catches highly magnetic atoms
A research team from the National Institute of Standards and Technology (NIST) and the University of Maryland has succeeded in cooling atoms of a rare-earth element, erbium, to within two millionths of a degree of absolute zero using a novel trapping and laser cooling technique. view more (2008-04-03)
NIST reference materials are 'gold standard' for bio-nanotech research
The National Institute of Standards and Technology (NIST) has issued its first reference standards for nanoscale particles targeted for the biomedical research community-literally "gold standards" for labs studying the biological effects of nanoparticles. view more (2008-01-10)
Toward a quantum computer, one dot at a time
Researchers at the University of Pittsburgh have developed a way to create semiconductor islands smaller than 10 nanometers in scale, known as quantum dots. view more (2006-01-20)
