A. Besides, some scientists note that any new product like this will need to stand up to the real world, where dirt coats surfaces over time. B. It is calculated that covering a 1, 000-square-foot roof with this new paint could cool a building by about 10 kilowatts. C. The price of barium sulfate is comparable to, or even slightly more expensive than, titanium dioxide that is used in some other commercial paints. D. Now it's time to shed some light on the other end of the practical paint spectrum: the "whitest white." E. That is to say, this new paint can be a tool to fight the climate emergency by cutting carbon emissions. F. Unfortunately, manufacturing precise layers of multiple substances and applying them to a surface in a set order costs more than simply slapping on some paint. |
Cool Colour
The "blackest black" paint, famed for its thermal disguise potential, has long absorbed 99.9 percent of public attention. Research shows that surfaces coated with a newly formulated white coloring reflect 98. 1 percent of sunlight, creating a powerful cooling effect.
This coating absorbs just 1.9 percent of sunlight compared with 10 to 20 percent for conventional white or "heat-reflective" paints, says Xiulin Ruan, a Purdue University mechanical engineer. By reflecting so efficiently, the novel paint can actually help a coated building release the heat inside."Our model shows if you're in, you can save up to 70 to 80 percent on air-conditioning in the summer," Ruan says.
Scientists have been developing reflective paints for decades, but commercial products still remain at or above the surrounding temperature. In the past 10 years researchers have found greater success with multilayered coating to reflect many wave-lengths of light.
Thus, Ruan decided to take a hybrid approach and create an ordinary paint that could easily be brushed or sprayed onto a surface. After testing particles of several different compounds, he and his colleagues ultimately selected a relatively inexpensive one called barium sulfate.
Actually, there is plenty of competition from other researchers. The manufacturers have to struggle with "how to make sure that the paint stays white after 30 years of use." However, Ruan says he and his colleagues do have the confidence to remove this fear. He hopes to bring a version of his paint to market in a year or two.

A study published Monday found that people who sleep less tend to be fat,and experts said it's time to find out if more sleep will fight fatness.
“We've put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep,”said Fred Turek,a physician at Northwestern University.
Monday's study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index-a measure of weight based on height increased.
“Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights,”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.
“Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients,”the study said.
“Our findings suggest that major extensions of sleep time may not be necessary,as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index,”it added.
“We caution that this study does not set up a causeandeffect relationship between restricted sleep and fatness,but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”
The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.
In an interview,Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone,and increases in another hormone that cause a longing for food.“In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠),”he said.
“Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States,”it added,“leading to a variety of health problems.”
