| Therefore, we have attempted to create a simple, reversible photochromic metal-ion chelator that can be analyzed quantitatively. |
| Demand for photochromic and polarized lenses is also rising beyond overall market demand. |
| This reversible deprotonation and reprotonation causes the distinguished visible and fully reversible photochromic shift from purple to yellow. |
| When a photochromic material is exposed to light, the light absorption properties of the material change. |
| With its photochemical cycle, bR represents a reversible photochromic system in addition to its charge translocation property. |
| Faulkner wore jeans faded at the knees, a broad hat, and photochromic sunglasses. |
