Young Chalmers Professor Awarded - again!
Professor Owe Orwar of the Department of Physical Chemistry at Chalmers University of Technology in Gothenburg, Sweden, will in March this year receive another prestigious prize, the 2003 Pittsburgh Conference Achievement Award. The award symposium will be presented at PITTCON 2003 to be held at the Orange County Convention Center in Orlando,... view more... (2003-01-16)
Empa scientists synthesize graphene-like material
Two-dimensional carbon layers, so-called graphenes, are regarded as a possible substitute for silicon in the semiconductor industry. view more (2009-11-24)
Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures. view more (2008-01-03)
U. T. Dallas-led research team produces strong, transparent carbon nanotube sheets
University of Texas at Dallas (UTD) nanotechnologists and an Australian colleague have produced transparent carbon nanotube sheets that are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays. view more (2005-08-19)
A new measure of global warming from carbon emissions
Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment has found a direct relationship between carbon dioxide emissions and global warming. view more (2009-06-11)
'High Q' NIST nanowires may be practical oscillators
Nanowires grown at the National Institute of Standards and Technology (NIST) have a mechanical "quality factor" at least 10 times higher than reported values for other nanoscale devices such as carbon nanotubes, and comparable to that of commercial quartz crystals. view more (2007-11-28)
Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers. view more (2007-07-13)
New Hybrid Nanostructures Detect Nanoscale Magnetism
A key challenge of nanotechnology research is investigating how different materials behave at lengths of merely one-billionth of a meter. When shrunk to such tiny sizes, many everyday materials exhibit interesting and potentially beneficial new properties. view more (2008-12-09)
Forests - just how absorbing are they?
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial "sinks" to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how... view more... (2003-03-13)
Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide view more (2006-04-13)
"Rational" Meccano
Nanofibrous carbon is interesting by itself: it consists of carbon fibres of 3 to 500 nm in diameter. These fibres can form " cylinders" (which make almost finished polymeric nanotubes), or a system of cones stowed one into the other at a certain angle to the fibre axis, or simply "wrapping package" - this is driven by the type of applied catalyst... view more...

Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere. view more (2007-05-14)
Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health. view more (2006-04-03)
Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. view more (2007-12-11)
Active carbon supercondenser
CIDETEC has just completed the project, subsidised by the Basque Government and CEGASA, "The development of a active carbon supercondenser for high-tension applications", aimed at developing home-grown technology which would allow the construction of an active carbon-based, double-layer prototype. Supercondensers (SC's) are made up of... view more... (2003-03-03)
World's smallest radio uses single nanotube to pick up good vibrations
Physicists at the University of California, Berkeley, have built the smallest radio yet - a single carbon nanotube one ten-thousandth the diameter of a human hair that requires only a battery and earphones to tune in to your favorite station. view more (2007-11-01)
Researchers Create Catalysts for Use in Hydrogen Storage Materials
A team of scientists from Virginia Commonwealth University, the University of Uppsala in Sweden, and the Savannah River National Laboratory have identified that carbon nanostructures can be used as catalysts to store and release hydrogen, a finding that may point researchers toward developing the right material for hydrogen storage for use in cars. view more (2009-03-25)
Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000. view more (2008-10-02)
Feather fibers fluff up hydrogen storage capacity
Scientists in Delaware say they have developed a new hydrogen storage method - carbonized chicken feather fibers - that can hold vast amounts of hydrogen, a promising but difficult to corral fuel source, and do it at a far lower cost than other hydrogen storage systems under consideration. view more (2009-06-24)
Guarding giants with tiny protectors
How do you build an infrared (IR) camera that is small enough to fit on a mini-unmanned aerial vehicle (UAV) without cryogenic cooling? Call in the nanobots. view more (2005-10-24)
