“…When ZnS is concerned the circumstances are more complex. In our previous research [ 41 ] the ZnS nanoparticles obtained by the mechanochemical synthesis dissolved in polymethyl methacrylate (PMMA) were studied. The experimental spectrum of the ZnS nanoparticle is characterized by several broader structures, broad multimodal features in 130–200 cm −1 region, along with the broad structures centered at 263, 346, and 425 cm −1 .…”

In the present work experimental study of the ZnO@ZnS core‐shell nanostructure with an active layer obtained by conversion of zinc oxide powders with H2S is reported. Тhe prepared structures were characterized by scanning electron microscopy, X‐ray diffraction, Raman spectroscopy, and far‐infrared spectroscopy. Top surface optical phonon (TSO) in ZnO, characteristic for the cylindrical nano‐objects, the surface optical phonon (SOP) mode of ZnS, and SOP modes in ZnO@ZnS core‐shell nanostructure are registered. Local mode of oxygen in ZnS and gap mode of sulfur in ZnO are also registered. This result is due to the existence of an active layer in the space between ZnO core and ZnS shell, which is very important for the application of these materials as thermoelectrics.

“…Their properties can be adjusted to fit the need that is demanded from the end user in terms of functionality. Multifunctional composite materials are in the center of the research enabling the preparation of materials at the same time having functionalities such as optical properties combined to mechanical properties 1 or combined optical, catalytic 2 and antibacterial properties. 3 Acrylate polymers are among the most used polymers in dentistry, 4 medicine, packaging, electronics but also in some architectural uses as they can be adapted to have a desired color, transparency, and strength.…”

Acrylate polymers are used in several applications such as dentistry, medicine, and industry. The modification of their properties using the reinforcement is of key importance for the possible applications. Layered double hydroxides are materials that are easily synthesized by several techniques giving the possibility to modulate the chemical composition and morphology of the reinforcement and they consist of a divalent and a trivalent anion hydroxide and the layers can be exfoliated and thus provide a material interesting for composite reinforcement. In this paper, Mn was used as a divalent and Al as a trivalent cation. The obtained particles were used as reinforcement for the preparation of composites in 1, 3, and 5 wt% quantities and prepared samples were compared to the matrix consisting of PMMA. Physical mechanical properties of the sample having the best mechanical properties (with 3 wt% of MnAl‐LDH filers) exhibited 6.38% modulus of elasticity, 27% hardness, and 10% tensile strength improved values compared to the clear PMMA matrix. Toughness was lowered in this sort of composite compared to the pure matrix.Highlights MnAl‐LDH‐PMMA composites improved modulus, strength, hardness Loss of toughness is tolerable for 3 wt% reinforcement Viscoelastic properties are improved for composites compared to matrix
