Two reviews “Synthesis of silica nanoparticles by sol-gel: size-dependent properties, surface modification, and applications in silica-polymer nanocomposites—a review,” and “Polymer/QDs nanocomposites for waveguiding applications.”

In the article “Synthesis of silica nanoparticles by sol-gel: size-dependent properties, surface modification, and applications in silica-polymer nanocomposites—a review,” the literature data on SiO2 nanoparticles obtainment and polymer nanocomposites synthesis by sol-gel method was considered, the possibilities of obtained product’s properties regulation and their application are analyzed.

At the review “Polymer/QDs nanocomposites for waveguiding applications,” were considered the possibilities of Active wave guides with use of Quantum Points CdTe and PMMA binding—polymer/QDs nanocomposites for wave-guiding on hybrid organic (polymer)—inorganic (quantum dots) materials applications.

The articles are devoted to the various applications. For example were obtained the following: in “Bragg grating optical filters by UV nanoimprinting,” the stable micro- and nanostructured optical devices, in “Polymer/QDs nanocomposites for waveguiding applications,” nanocomposites for wave-guiding, in “Introduction of bifunctional group onto MWNT by radiation-induced graft polymerization and its use as biosensor-supporting materials,” biosensor for the detection of phenolic compounds in drinks such as red wine and juices and the zinc oxide nanowires, used directly as negative electrode materials for photovoltaic devices as well, and so on.

The following 26 papers can be conventionally divided to the four groups.
