Photoisomerization

In chemistry, isomerism refers to the fact that two molecules have the same gross formula but different structural formulas, and by extension different spatial structures. By modifying the molecule's geometry through isomerization, it is possible to modulate the interactions that change the structure of the bulk material, modify spectroscopic properties and so on.

Phototaxis; phototaxy

Phenomenon by which material or biological objects direct themselves or their movements according to the light activated in their periphery.

Holography; holography

Holography is a process for recording the phase and amplitude of a wave diffracted by an object. A hologram is produced by illuminating an object with a laser source and recording on a photosensitive surface...
