New York rooftops 40 degrees cooler painted white, reckons NASA/Columbia study

By - March 8, 2012 4 Pictures
It's long been suggested that white rooftops could help reduce the heat bubble microclimates that surround our cities simply by reflecting solar radiation directly back into space, and in 2010 we reported on NCAR efforts to demonstrate the effect through computer modeling. A new study goes one better, putting the theory into practice and pitting three white materials against one another on three New York rooftops. The results of the study appear to be overwhelmingly positive, with white roof coatings reducing peak rooftop temperatures in summer "by an average of 43 degrees Fahrenheit (about 24 degrees C)."

Smart paint could slash costs of structural monitoring

By - January 30, 2012 3 Pictures
Current monitoring of large structures such as bridges, wind turbines and mines generally relies on time consuming visual inspections that use specialized instrumentation and equipment. Translation: it's expensive. But if damage can be detected before any structural damage occurs, maintenance bills can also be significantly reduced and safety increased. Researchers at the University of Strathclyde in Glasgow are tackling the issue with a smart paint they claim not only detects microscopic faults before structural damage occurs, but does so at a cost of just one percent of current widely used inspection methods.

Nissan announces world's first self-healing iPhone case

By - January 16, 2012 3 Pictures
Just over six years ago, we reported that Nissan had developed a "Scratch Guard Coat" paint designed to repair scratches on not only cars, but on painted surfaces in general. The company has already applied its paint technology to a number of Nissan and Infiniti models, and in 2009 it announced that it would license it for use on mobile phones. It appears there weren't many takers as Nissan has now announced that it has produced the world's first self-healing iPhone case that makes use of the Scratch Shield paint. Read More

Researchers develop cheap and easy to mass-produce "solar-paint"

By - December 21, 2011 2 Pictures
A team of researchers from the University of Notre Dame in Indiana is reporting the creation of a "solar paint" that could mark an important milestone on the road to widespread implementation of renewable energy technology. Although the new material is still a long way off the conversion efficiencies of commercial silicon solar cells, the researchers say it is cheap to make and can be produced in large quantities.

Painter gives bicycle frames the woodgrain look

By - July 20, 2011 12 Pictures
Whether it’s the Renovo/Audi duo lineup, the just-announced Lagamorph, or one of the various bamboo creations, wooden-framed bikes (or in the case of bamboo, “wooden”-framed) are becoming more and more popular. While this is partly because of the ride characteristics and eco-friendliness of sustainably-harvested wood, let’s be honest – it’s mostly because they look nice. Unfortunately, they also tend to be pricey, with a single complete bike costing several thousand dollars. Well, if it’s just the aesthetic of wood that you want, now you have an alternative ... New Zealand’s Rob Pollock will give your frame a hand-painted woodgrain finish, for just US$1,500. Read More

New polymers self-heal scratches in UV light

By - April 21, 2011 1 Picture
Nobody likes scratches in their car's finish. That's part of the reason why over the years, a number of research facilities have tried to develop self-healing paint. These efforts have resulted in products containing things such as microcapsules that burst open when scratched, elastic resins, and even a chemical derived from the exoskeletons of crustaceans. Now, scientists from the U.S. and Switzerland have developed polymers – which could be used in paint – that heal their own scratches when exposed to ultraviolet light. Read More

Flow - a paintbrush with real bristles for use on touchscreens

By - April 20, 2011 3 Pictures
Anyone who has finger-painted, sketched with a pencil and painted with a brush will tell you that the three activities feel different when you're doing them, and that feel influences the look of the finished piece of artwork. It would seem to follow that if you were trying to simulate the experience of using a paintbrush when creating art on a touchscreen device, you would use a brush, and not a stylus or your finger ... that's the thinking behind the Flow, a capacitive paintbrush designed for use on the iPad and similar devices.

'Hearing' paint pigments helps restore historic masterpieces

By - September 7, 2010 1 Picture
DaVinci, Caravaggio, VanGogh and Monet are just a few of the artists whose works attract thousands of visitors every year. However these paintings often suffer from damage due to aging and exposure to the elements. What once was a masterpiece on a church ceiling or wall often requires a highly skilled restoration team to return it to its original form – a process which is being aided by researchers at McGill University in Quebec, who have used a technique called "photoacoustic infrared spectroscopy" to identify the composition of pigments used in art works.

The YrWall digital graffiti video wall

By - August 5, 2010 8 Pictures
Graffiti murals can be truly amazing pieces of artwork, but when it comes to indoor graffiti-making events... well, those spray paints aren’t exactly fume-free, nor are they particularly forgiving to people trying their hand at the art form for the first time. That’s where the YrWall Digital Graffiti Wall comes in. Designed by startup British tech company Lumacoustics, YrWall consists of a video wall that users "paint" on using a modified spray paint can - it “sprays” infrared light, and is tracked by a computer. Much like Microsoft Paint, users can select different colors and effects from a palette, fill in areas with a given color, insert pre-made graphics, and delete their mistakes. When they’re done, they can save their projects, share them online using an onscreen keyboard, or even get them printed on T-shirts. Read More
