Study Proposes that 'Nanosphere' Paint Could Reduce CO2 Emissions from Airplanes## Paint Made from ‘Nanospheres’ Could Cut Airplane CO2 Emissions

In the realm of commercial aviation, each gram counts. A team of materials scientists from Kobe University have made a pivotal discovery that could transform the aviation sector. They’ve identified “nanospheres”, virtually invisible silicon crystals that can reflect light due to their large and effective scattering capabilities. This finding was expounded in a scientific paper published in the ACS Applied Nano Matter journal.

Understanding the Science of Nanospheres

The nanospheres discovered by Minoru and Hiroshi use structural color instead of pigment color to display and maintain hues. Contrary to pigment colors that absorb wavelengths and reflect those visible to the human eye, structural colors are intense and bright as they interact with micro- and nanostructures.

Possible Uses of Nanosphere Paint

The most immediate commercial advantage of this discovery is its application in airplanes. The nanosphere paint could envelop a surface in rich color while only contributing 10 percent of the weight of painting an aircraft for the same visual effect. This could notably decrease CO2 emissions in the aviation sector. Moreover, its potential uses extend beyond the aviation industry due to its exceptional brightness.

The discovery of nanosphere paint could have considerable impact on the aviation industry and other sectors. By cutting down the weight added by paint, CO2 emissions could be significantly reduced, which will contribute to a more sustainable future.


Q: Can you explain what nanospheres are?
A: Nanospheres are almost invisible silicon crystals capable of reflecting light due to their large and effective scattering.

Q: How does nanosphere paint help reduce CO2 emissions in airplanes?
A: Nanosphere paint can coat a surface in vivid color while only adding 10 percent of the weight typically added by painting an aircraft for the same visual outcome. This decrease in weight can result in lower CO2 emissions.

Q: What could be the potential uses of nanosphere paint?
A: While its most immediate use is in the aviation sector, this paint’s potential uses go beyond this due to its intense brightness. It could be valuable in any industry where vibrant color and low weight are key factors.

Q: Can you differentiate between structural color and pigment color?
A: Pigment colors absorb wavelengths and reflect those that the human eye can detect. On the contrary, structural colors are radiant and vivid as they interact with micro- and nanostructures.
