The National Center for Atmospheric Research will fly a C-130 research aircraft over Colorado’s Front Range this May and July to measure how much carbon dioxide mountain forests remove from the air as spring turns into summer. NCAR scientists and their university colleagues are developing new methods for assessing carbon uptake over complex terrain on regional scales. Accurate assessments could help show to what extent carbon dioxide storage in Western mountain forests-- a potentially important "sink" for the greenhouse gas--may be slowing down as the ongoing drought affects tree growth.
International pressure is mounting to limit carbon emissions because of their role in global climate change. Better understanding of natural processes involved in forest-air carbon exchange may lead to more accurate monitoring methods and new ways to enhance carbon uptake. High carbon-emitting nations and industries are interested in devising strategies for meeting quotas and trading carbon credits.
ACME (short for the Airborne Carbon in the Mountains Experiment) gives scientists an opportunity to combine airborne data with ground-based measurements for the first time to paint a more accurate picture of carbon exchanges in rolling hills and mountain ranges. Results from the field program will also be used in testing computer models of forest ecosystem function. The models will help scientists understand the response of forests to drought, fire, insects, and climate change.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
