Direct imprint of optical skyrmions in azopolymers as photoinduced relief structures

APL Photonics
Skyrmions, topologically stable configurations of a three-component vector field with sophisticated textures, have been considered in many contexts, including atomic physics, Bose–Einstein condensates, liquid crystals, and magnetic materials.

Multi‐Color Optical Quasiparticle Laser Source Formed of a Pr3+ Doped Fiber Laser with a Dual‐Output Coupling Geometry

Laser &Photonics Reviews, Volume 19, Issue 4, February 19, 2025.
Multicolor visible optical quasiparticles (bimerons and skyrmions) source is demonstrated by employing a diode‐pumped Pr3+‐doped fluoro‐aluminate glass (Pr3+: WPFG) fiber laser with a wedge‐output coupler. This robust and cost‐saving system explores potentially innovative applications in materials science and biotechnologies. Abstract The generation of

Reversible Demountable Coating Films Composed of Trifunctional Liquid Anthracene Compounds and Evaluation of Their Adhesive Properties

Macromolecular Chemistry and Physics, Volume 226, Issue 4, February 2025.
For various adherends, a light‐cured film of a trifunctional liquid anthracene compound is used as a primer layer prior to adhesion. This provides a thermally dismantlable adhesive bond. Abstract Technologies that facilitate recycling are attracting considerable interest from the perspective of resource constraints.

Photoinduced birefringence in azopolymer doped with Au nanoparticles

Journal of Physics: Conference Series, 2019
Abstract A study of the photoinduced birefringence in nanocomposite thin films of the azopolymer PAZO (poly[1-[4-(3-carboxy-4-hydroxyphenylazo)benzenesulfonamido]-1,2-ethanediyl, sodium salt]) doped with gold (Au) nanoparticles (NPs) is presented. The NPs are with a spherical shape and mean size 10 nm.

Amphiphilic azopolymers capable to generate photo-sensitive micelles

Open Chemistry, 2011
AbstractAmphiphilic macromolecular micelles are advantageous for drug delivery applications due to the decrease of side-effects, ease of screening drugs against degradation, long-term stability, targeted delivery and control of the amount of the released drug.
