NEW COMPOUND COULD BECOME \u201cCOOL BLUE\u201d FOR ENERGY EFFICIENCY IN BUILDINGS<\/a><\/p>\n

CORVALLIS, Ore. \u2013 A new type of durable, environmentally-benign blue pigment discovered at Oregon State University has also been found to have unusual characteristics in reflecting heat \u2013 it\u2019s a \u201ccool blue\u201d compound that could become important in new approaches to saving energy in buildings.<\/p>\n

\u201cThis pigment has infrared heat reflectivity of about 40 percent, which is significantly higher than most blue pigments now being used,\u201d said Mas Subramanian, an OSU professor of chemistry who discovered the compound.<\/p>\n

\u201cThe more we discover about the pigment, the more interesting it gets,\u201d Subramanian said. \u201cWe already knew it had advantages of being more durable, safe and fairly easy to produce. Now it also appears to be a new candidate for energy efficiency.\u201d<\/p>\n

\u201cCool roofing,\u201d in which paints are used to reflect significant portions of the sun\u2019s heat and thereby reduce cooling costs, is an important new trend in \u201cgreen\u201d construction and energy efficiency, experts say. Such reflective coatings also are more aesthetically pleasing, have less thermal degradation, reduce the \u201cheat island\u201d effect in cities, lower peak energy demand, and reduce air pollution due to lower energy use and power plant emissions.<\/p>\n

\u201cWe\u2019re seeking licensing partners for this invention right now,\u201d said Mary Phillips, associate director of the Office for Commercialization and Corporate Development at OSU. \u201cWe believe it can contribute to new energy efficiency solutions around the world.\u201d<\/p>\n

In general, any darker color of the type often used for roofs, houses, automobiles or other applications will tend to absorb more heat. But some compounds, like the one discovered at OSU, have dark tones but also the ability to reflect heat in the infrared spectrum, which is responsible for most of the heat energy absorbed from sunlight.<\/p>\n

The material created at OSU, researchers say, is probably the best blue pigment humans have produced since ancient times \u2013 going back to efforts by the Egyptians, the Han dynasty in China and Mayan cultures. Blue pigments have been sought through history but often had serious drawbacks, such as decaying quickly, being toxic, costly or carcinogenic.<\/p>\n

In research funded by the National Science Foundation, OSU scientists discovered this material by coincidence while they were looking for something else.<\/p>\n

Some manganese compounds came out of a 2,000 degree Fahrenheit oven transformed into a beautiful blue, which researchers later determined was due to\u00a0an unusual \u201ctrigonal bipyramidal coordination\u201d<\/a> of their molecules that changed when exposed to extreme heat.<\/p>\n

Research will continue at OSU on the heat reflectance capabilities of the new compound and the underlying molecular structure responsible for it, scientists said.<\/p>\n

About the OSU College of Science: As one of the largest academic units at OSU, the College of Science has 14 departments and programs, 13 pre-professional programs, and provides the basic science courses essential to the education of every OSU student. Its faculty are international leaders in scientific research.<\/div>\n

OSU-discovered compound could keep buildings cool<\/a><\/h1>\n<\/div>\n

Researchers at Oregon State University have discovered a chemical compound, a “cool blue” pigment that has notable heat reflecting properties that could lead to new approaches to saving energy in buildings.<\/p>\n

The patent-approved compound could be used to develop roofing paint and other products that would reduce heat absorption.<\/p>\n

“The pigment has infrared heat reflectivity of about 40 percent, which is significantly higher than most blue pigments now being used,” said\u00a0Mas Subramanian, the OSU professor of chemistry<\/a> who discovered the compound, in a press release.<\/p>\n

Subramanian said the pigment is also safe, durable and relatively easy to produce.<\/p>\n

Mary Phillips, associate director of OSU’s office for commercialization and corporate development, said the university is looking for licensing partners to develop the compound into products.<\/p>\n

“We believe it can contribute to new energy efficiency solutions around the world,” Phillips said.<\/p>\n

OSU said the manganese compound \u2014 molecules transformed by a 2,000-degree Farenheit oven into a beautiful blue \u2014 was discovered in research funded by the National Science Foundation.<\/p>\n

Researchers say it’s probably the best blue pigment humans have produced since ancient times \u2013 going back to efforts by the Egyptians, the Han dynasty in China and Mayan cultures. Blue pigments have been sought through history but often had serious drawbacks, such as decaying quickly, being toxic, costly or carcinogenic.<\/p>\n
