Photophysics and photochemistry of NIR absorbers derived from cyanines: key to new technologies based on chemistry 4.0

open access: yesBeilstein Journal of Organic Chemistry, 2020
Cyanines derived from heptamethines were mainly discussed regarding their functionalization to broaden the solubility in different surroundings exhibiting either hydrophilic or hydrophobic properties and to tailor made the ΔGet photopysical properties ...

Full-Color See-Through Three-Dimensional Display Method Based on Volume Holography

open access: yesSensors, 2021
We propose a full-color see-through three-dimensional (3D) display method based on volume holography. This method is based on real object interference, avoiding the device limitation of spatial light modulator (SLM).

Rheological Study of the Solidification of Photopolymer and Dispersed Nanotube Systems

open access: yesApplied Rheology, 2011
We herein describe a set of rheological measurements that were carried out in order to characterize the solidification of photopolymers. The solidification depends on the length of time of exposure to UV light, and the intensity of that light, which ...

New Materials by Photopolymerization

open access: yesCHIMIA, 1993
Despite lateral resolution being the most intensely studied topic in photopolymer research, vertical resolution properties finally add the decisive momentum to reach the desired performance in photopolymer layers. We will describe four different
