Study shows lead-based paint problem isn't isolated to China
A multinational team of environmental and occupational health researchers has found that consumer paints sold in Nigeria contain dangerously high levels of lead. Increased globalization and outsourcing of manufacturing has drastically increased the likelihood that products with unacceptably high levels of lead are being traded across borders -- including between China and Africa as well into regulated countries like the US.

Hidden treasure: Technique reveals buried image in famed illustrator's painting
Researchers are reporting the use of a new X-ray imaging technique to reveal unprecedented details of a painting hidden beneath another painting by famed American illustrator N.C. Wyeth. The nondestructive technique could reveal new insights into the artist's technique, and potentially reveal hidden images in hundreds of Old Master paintings, the researchers say. Their study is scheduled for presentation in August at the 238th National Meeting of the American Chemical Society in Washington, D.C. (2009-08-19)

Busting rust with light: New technique safely penetrates top coat for perfect paint job
To keep your new car looking sleek and shiny for years, factories need to make certain that the coats of paint on it are applied properly. But ensuring that every coat of paint -- whether it is on a car or anything else -- is of uniform thickness and quality is not easy. Now researchers have developed a new way to measure the thickness of paint layers and the size of particles embedded inside. (2014-05-20)

This white paint keeps surfaces cooler than surroundings, even under direct sunlight
Scientists have developed a white paint that cools below the temperature of its ambient surroundings even under direct sunlight. Their research, published October 21, 2020 in the journal Cell Reports Physical Science, demonstrates a radiative cooling technology that could be used in commercial paints, that could be less expensive to manufacture, and that passively reflects 95.5% of sunlight that reaches its surface back into outer space. (2020-10-21)

Speeding up 19th century oil paintings
The fluid and loose brushwork used by J.W.M. Turner and other innovative 19th century artists to capture the momentary effects of light was technically made possible by the addition of 'gumtion' or 'megilp' to the paint matrix, which gave the paints the jelly-like consistency needed for their impasto-rich paintwork. In the journal Angewandte Chemie, scientists unveil the crucial role lead acetate played in this gelation process. (2017-01-09)

Paint absorbs corrosion-causing chemicals, kitty-litter style
Engineers at Ohio State University have incorporated clay and other chemicals into a paint that keeps metal from corroding -- and reveals when an airplane, boat, or bridge needs to be repainted. Though the paint is still under development, early tests have shown that it prevents corrosion just as well as commercial paints that are less environmentally friendly. (2004-08-23)

Restoration based on chemistry
Considered the pinnacle of mediaeval painting, the Ghent Altarpiece was painted around 1432 by Jan van Eyck and probably his brother Hubert. It is currently undergoing the most extensive conservation treatment for more than a century. The decision to remove all overpaint was underpinned by scientific arguments: Belgian researchers report in the journal Angewandte Chemie about their use of 'chemical maps' to visualize the original paint layers under the overpainted surface. (2017-04-03)

Ancient war paint in fight against breast cancer
Woad, an ancient dye plant has been found to be a rich source of the anti-cancer compound, glucobrassicin, traditionally associated with broccoli. Glucobrassicin has been found to be effective against breast cancer. Woad, from the Brassicaceae family has 20 times more of the cancer fighting chemical than broccoli. Italian scientists have enhanced these levels by wounding the plant, which releases glucobrassicin as a defence mechanism. The chemical is particularly effective at degrading estrogen, which increases the risk of breast cancer in women. (2006-08-13)

Paint job transforms walls into sensors, interactive surfaces
Walls are what they are -- big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used. Researchers at Carnegie Mellon University and Disney Research found that they could transform dumb walls into smart walls at relatively low cost using simple tools and techniques, such as a paint roller. (2018-04-23)

Chemists and curators join forces to save Old Masters
It's enough to make the 'Mona Lisa' stop smiling. In an effort to preserve old paintings, collectors and curators unknowingly used untested and risky techniques that are causing the polymers forming their paints to fall apart.

Scientists 'paint' viruses to track their fate in the body
Here's a new twist on the relationship between biology and art. In an article recently published online in the FASEB Journal, researchers describe how they were able to coat -- or paint -- viruses with proteins. This breakthrough should boost the efficiency of some forms of gene therapy, help track and treat viral disease and evolution, improve the efficiency of vaccines, and ultimately allow health-care professionals track the movement of viral infections within the body. (2008-05-20)

Lead-based paint is poisoning albatross chicks at Midway Atoll National Wildlife Refuge
Lead-based paint from deteriorating buildings still poses a hazard to wildlife on Midway Atoll, despite extensive environmental remediation efforts undertaken as part of the conversion of the site from a military base to a national wildlife refuge. A new study shows that Laysan albatross chicks in nests near the buildings are suffering lead poisoning as a direct result of eating paint chips from the soil in and around their nests. (2003-07-02)

New shapes of laser beam 'sneak' through opaque media
Researchers have found a way to pre-treat a laser beam so that it enters opaque surfaces without dispersing -- like a headlight that's able to cut through heavy fog at full strength. The discovery from scientists at Yale University and the Missouri University of Science & Technology has potential applications for deep-tissue imaging and optogenetics, in which light is used to probe and manipulate cells in living tissue. (2019-03-04)

Improved pavement markings can save lives
As spring finally emerges after a ferocious winter, our battered roads will soon be re-exposed. While potholes and cracks might make news, a bigger concern should be the deterioration to pavement markings, from yellow to white lines, which are a big factor in preventing traffic accidents. A study from Concordia University, funded by Infrastructure Canada and published in Structure and Infrastructure Engineering, found that snowplows are the biggest culprit in erasing roadway markings. (2014-03-19)

Celestial bodies born like cracking paint
Researchers have explained why objects in the universe come in a wide variety of sizes, from the largest stars to the smallest asteroids -- and it has a lot to do with how paint cracks when it dries. When a volume is under internal tension -- as the early universe was due to gravity -- the most efficient way to relieve that tension is by 'cracking' hierarchically -- few large and many small. (2016-03-01)

(2010-08-15)

Scientists use modern technology to understand how ochre paint was created in pictographs
Ochre was often used as a vivid red paint in ancient rock art known as pictographs. Despite its broad use throughout human history and a modern focus on how the artistic symbolism is interpreted, little research exists on the paint itself and how it was produced. Now, scientists are using electron microscopes to understand how ochre paint was created by hunter-gatherers in North America to produce rock art located at Babine Lake in British Columbia. (2019-11-19)
