AB  - Nanostructured cadmium selenide (CdSe) and lead sulfide (PbS) semiconductors were prepared in a poly(2-(dimethylamino)ethyl methacrylate-co-acrylic acid) matrix. The obtained nanoparticles were characterized by using optical and structural methods. Co-polymers were synthesized in two different molar ratios of pDMAEMA: acrylic acid monomer units (1 : 2, 1 : 1). Transmission electron microscopy analysis confirmed the presence of nano-sized CdSe and PbS particles. In the case of CdSe, a shift of the onset of the optical absorption toward lower wavelengths was observed. X-ray diffraction analysis revealed that both CdSe and PbS nanoparticles have cubic crystal structure.

AB  - Poly(2-(dimethylamino)ethyl methacrylate-co-acrylic acid) polyampholyte copolymers were synthesized by radical polymerization of the co-monomers in different molar ratios (2-1, 1-1 and 1-2). The water solutions of the obtained materials were used as stabilization agents for the synthesis of silver nanoparticles. XRD. FTIR and DMA methods were used to study the physical properties of the pure copolymers. It was found that the copolymer is a completely amorphous and inhomogeneous material. The FTIR spectrum was analysed by using literature data and corresponding numerical simulations. TEM analysis showed that the shape of the nanoparticles prepared by reduction of the silver salt in the presence of co-polymers strongly depends on the ratio of DMAEMA and AA co-monomer units. Besides spherical Ag-nanoparticles, reduction in the presence of the polymer with equal molar content of co-monomers also resulted in the formation of nano-plate particles (circular thin plates and thin triangular nanoprisms). The formation of the nano-plate particles was further promoted by heating the mentioned solution at 60 degrees C in air. UV-vis spectroscopy was used to study the change in the surface plasmon resonance behaviour during the growth of the nanoplates. The Ag-nanocomposite thin films of all three co-polymers showed fast antimicrobial activity against the Staphylococcus aureus, Escherichia coli and Candida albicans pathogens (more than 99% reduction after 2 h of exposure).

AB  - A synthetic procedure for the encapsulation of cadmium selenide (CdSe) nanoparticles in a sago starch matrix is introduced. The nanocomposite was investigated using structural, spectroscopic and thermal, methods. TEM micrographs of the nanocomposite showed spherical CdSe particles of 4-5 nm in size coated with a biopolymer layer. The absorption edges of both the aqueous solution and the thin film of the CdSe-starch nanocomposite were shifted toward lower wavelengths in comparison to the value of the bulk semiconductor. Infrared measurements revealed that the interaction of CdSe nanoparticles and starch chains takes place via OH groups. Although the onset of the temperature of decomposition of CdSe-starch nanocomposite is lower than that of the pure matrix, thermogravimetric analysis also showed that introduction of CdSe nanoparticles significantly reduced starch degradation rate leading to high residual mass at the end of the degradation process.

AB  - Tri-n-octylphosphine oxide-capped CdS nanoparticles were synthesized with the cadmium(II) complex of thiocarbohydrazide as a precursor. Nanocomposites were prepared by mixing a toluene solution of poly(ethylene oxide) (PEO) and the obtained CdS nanoparticles. The ultraviolet-visible spectroscopy measurements showed a blue shift of the onset of optical absorption, compared to bulk CdS, which confirmed the presence of nanostructured CdS. A transmission electron microscopy micrograph of the nanocomposite depicted that the nanoparticles are well dispersed in the PEO matrix. Differential scanning calorimetry analysis revealed hindered crystallization of PEO in the presence of CdS nanoparticles. It was also found that increasing the nanoparticle content led to the shift of the onset of decomposition of the matrix towards higher temperature.

The average size of the nanoparticles varied from 3.6 to 5 nm, depending on the initial concentration of cadmium acetate during the nanocomposite preparation. Fluorescence measurements of the sago-CdS nanocomposite film showed broad emission in the orange-red part of the spectrum.

AB  - Silver (Ag) and silver sulfide (Ag2S) nanoparticles were synthesized in a sago starch matrix. The resulting nanocomposites were investigated using structural, optical and thermal methods. XRD spectra of the nanocomposites confirmed the presence of nanostructured silver (cubic phase) and silver sulfide (monoclinic phase) in the matrix. TEM micrographs showed that the nanoparticles are mostly spherical in shape. Analyzes of the optical properties of the silver nanocomposite aqueous dispersions/solutions of various concentrations were carried out. The results and the theoretical considerations suggested that at high concentrations there is a release of silver nanoparticles from the composite in the water environment. Further dilution produces homogeneous solution in which silver nanoparticles are capped with starch macromolecules. TGA analysis revealed reduced thermal stability of the nanocomposites with respect to pure starch matrix.

abstract = "Silver (Ag) and silver sulfide (Ag2S) nanoparticles were synthesized in a sago starch matrix. The resulting nanocomposites were investigated using structural, optical and thermal methods. XRD spectra of the nanocomposites confirmed the presence of nanostructured silver (cubic phase) and silver sulfide (monoclinic phase) in the matrix. TEM micrographs showed that the nanoparticles are mostly spherical in shape. Analyzes of the optical properties of the silver nanocomposite aqueous dispersions/solutions of various concentrations were carried out. The results and the theoretical considerations suggested that at high concentrations there is a release of silver nanoparticles from the composite in the water environment. Further dilution produces homogeneous solution in which silver nanoparticles are capped with starch macromolecules. TGA analysis revealed reduced thermal stability of the nanocomposites with respect to pure starch matrix.",

AB  - A synthetic procedure for the incorporation of PbS nanoparticles in a polyacrylamide (PAM) matrix was introduced. The method is based on the simultaneous polymerization of the monomer and thermal decomposition of the dithiooxamide-lead complex. XRD analysis revealed that PbS nanoparticles have a sphalerite crystal structure (galena). The TEM micrograph showed spherical particles, with average diameter of about 3 nm, well dispersed in the polymer matrix. Although a sharp edge was not observed, the optical absorption of the PAM-PbS nanocomposite is shifted towards lower wavelengths compared to the bulk PbS.
