DURHAM, N.C. -- Crazy bands are cool because no matter how long they've been stretched around a kid's wrist, they always return to their original shape, be it a lion or a kangaroo.
Now a Duke and Stanford chemistry team has found a polymer molecule that's so springy it snaps back from stretching much smaller than it was before.
MIAMI, FL (AUGUST 26, 2010) -- The cover story of the most recent issue of National Geographic Magazine (August 2010) features a University of Miami (UM) led expedition to the underwater caves of the Bahamas, known as 'blue holes.' These unique environments are one of the least understood ecosystems on the planet, largely due to the challenges involved in studying these extreme environments, which include complete darkness, dramatic reversing currents, extreme depths, poisonous gasses, and silty, tight squeezes.
ANN ARBOR, Mich.---Halogen bonding, hyperconjugation, electroactive polymers---such subjects are typical fare in graduate-level chemistry courses. But how many classes challenge students to explain the concepts to the whole world?
A new study by researchers at the Stockholm Environment Institute (SEI) at the University of York calls for better engagement of older people on climate change issues.
The report, prepared in partnership with the Community Service Volunteers' Retired and Senior Volunteer Programme (RSVP), urges the scrapping of stereotypes which suggest that older people are incapable of engagement, passive or disinterested in climate change.
When you tear open a bag of potato chips or pop in a DVD, you're probably putting your hand on sputter deposition. No, don't run for the soap.
Imagine loosening the screw-top of a soda bottle and hearing the carbon dioxide begin to escape. Then imagine taking the cap off quickly, and seeing the beverage foam and fizz out of the bottle. Then, imagine the pressure equalizing and the beverage being ready to drink.
Rutgers marine scientist Elisabeth Sikes and her colleagues say that something very similar happened on a grand scale over a 1,000 year period after the end of the last ice age – or glaciation, as scientists call it.
The North American continent is not one thick, rigid slab, but a layer cake of ancient, 3 billion-year-old rock on top of much newer material probably less than 1 billion years old, according to a new study by seismologists at the University of California, Berkeley.
BOSTON, Aug. 25, 2010 — Scientists today at the 240th American Chemical Society (ACS) National Meeting & Exposition described development and successful initial tests on a substance that acts as a sunscreen for the microscopic spores of a fungus, brightening prospects for wider use of the fungus as a means of wiping out insect pests that attack food crops.
College Park, MD (August 24, 2010) -- Chinese scientists have shown that magnetic memory, logic and sensor cells can be made faster and more energy efficient by using an electric, not magnetic, field to flip the magnetization of the sensing layer only about halfway, rather than completely to the opposite direction. They describe the new cell design in the Journal of Applied Physics, which is published by the American Institute of Physics (AIP).
Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary to use other molecules as messengers. A team of physicists and chemists including Dr.
Scientific findings by international research group of scientists from England, China and Denmark just published suggest that sea level will likely be 30-70 centimetres higher by 2100 than at the start of the century even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and greenhouse gas emissions are stringently controlled.
OAK RIDGE, Tenn., August 23, 2010 -- Nanoscale simulations and theoretical research performed at the Department of Energy's Oak Ridge National Laboratory are bringing scientists closer to realizing graphene's potential in electronic applications.
A research team led by ORNL's Bobby Sumpter, Vincent Meunier and Eduardo Cruz-Silva has discovered how loops develop in graphene, an electrically conductive high-strength low-weight material that resembles an atomic-scale honeycomb.
A team of scientists at Rutgers University has found a material in which an electric field can control the overall magnetic properties of the material. If the magnetoelectric effect discovered by the Rutgers group can be extended to higher temperatures, it could be useful for manipulating small-scale magnetic bits in ultra high-density data storage. The research appears in the current issue of Physical Review Letters.
