Lightweight composite changes color to warn that it’s been stressed

When lightweight composite materials are used in fields such as aerospace, it’s vitally important to know if they’re experiencing mechanical stress – before they fail. A new composite is able to do so, simply by fluorescing under UV light.Continue Read… Continue reading Lightweight composite changes color to warn that it’s been stressed

Immunity-boosting silica nanoparticles could replace pesticides

Pesticides may indeed kill plant pathogens, but they’re also harmful to the environment. Newly developed nanoparticles may provide a more eco-friendly alternative, as they boost the immune systems of crop plants, then harmlessly dissolve.Continue Readi… Continue reading Immunity-boosting silica nanoparticles could replace pesticides
