Multifunctional Gas and pH Fluorescent Sensors Based on Cellulose Acetate Electrospun Fibers Decorated with Rhodamine B-Functionalised Core-Shell Ferrous Nanoparticles.

Ferrous core-shell nanoparticles consisting of a magnetic γ-FeO multi-nanoparticle core and an outer silica shell have been synthesized and covalently functionalized with Rhodamine B (RhB) fluorescent molecules (γ-FeO/SiO/RhB NPs). The resulting γ-FeO/SiO/RhB NPs were integrated with a renewable and naturally-abundant cellulose derivative (i.e.

Microspheres Formation in a Glass-Metal Hybrid Fiber System: Application in Optical Microwires.

Multicomponent optical fibers with incorporated metals are promising photonic platforms for engineering of tailored plasmonic structures by laser micromachining or thermal processing. It has been observed that during thermal processing microfluidic phenomena lead to the formation of embedded micro- and nanostructures and spheres, thus triggering the technological motivation for their theoretical investigation, especially in the practical case of noble metal/glass composites that have not yet been investigated. Implemented microwires of gold core and glass cladding, recently studied experimentally, are considered as a reference validation platform.
