The combination of plant-based particles and water forms an 'eco' super-glue

EurekAlert   -   Scientific News Websites

Plant-based cellulose nanocrystals have remarkable inherent properties, and when combined with water, a powerful adhesive is formed that competes in strength with Superglue, without the need for toxic solvents.

Going super small to get super strong metals

EurekAlert   -   Scientific News Websites

Metals get stronger as the size of the grains making up the metal get smaller -- up to a point. If the grains are smaller than 10 nanometers in diameter the materials are weaker because, it was thought, they slide past each other like sand sliding...
