Abstract: Hylocomium splendens, species of moss frequently used for biomonitoring purposes, was subjected to metal oxide nanoparticle suspensions (nano-TiO2, nano-ZnO) in known concentrations in order to assess its applicability in biomonitoring of metal oxide nanoparticle pollution. After weekly subjecting the samples of the moss to the suspensions for up to eight weeks, the samples were digested and the metal content was analyzed by ICP-AES. [..] Read more

Abstract: To model the quantitative relationship of the nanoparticle toxicity we can use theoretical molecular descriptors or physico-chemical characteristics. The former provide an auspicious interpretation of the toxicity mechanisms, however their computation may be very demanding, namely in the nanoscale. [..] Read more

Abstract: Environmentally friendly polymers can be produced by modification of non-biodegradable synthetic polymers with a biodegradable polymer. Polypropylene (PP) is a thermoplastic polymer difficult to be decomposed by microorganisms in environment. [..] Read more

Abstract: Polyamide plays an important role in biomedical application such as suture material, coated textile against skin infection, wound dressing, catheters and bone tissue scaffolds. Surface modification of polyamide is very crucial factor to improve its performances by imparting desirable biomaterial properties. [..] Read more

Abstract: We have investigated the temperature and shell thickness effects on the extinction and photoluminescence (PL) optical properties in II-VI semiconductor core-shells of type I. To this purpose, we used Maxwell-Garnett (M-G) effective theory by defining appropriate dielectric functions for the constitutive materials of the core-shells. [..] Read more

Abstract: We reveal the mechanism of Ge nanoparticles (NPs) formation on the surface of the hydrogenated amorphous silicon (a-Si:H) deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD) on ITO and a on boron doped nanocrystalline diamond (BDD). The coating of Ge NPs on a-Si:H was performed by molecular beam epitaxy (MBE) at temperatures up to 450 °C. [..] Read more

Abstract: The investigation on the formation and morphology changes of magnetite nanoparticles is done in this work in order to estimate the origin of earlier observed phenomena resulting in the formation of 2D shaped nanoparticles of magnetite at certain conditions during one-step precipitation of magnetite nanoparticles from Mohr' s salt solution with strong base (NaOH). The impact of temperature, mixing and amount of base added during the precipitation reaction is evaluated in this study. [..] Read more

Abstract: Doped zinc oxide colloids can exhibit photoluminescence. In printing industry, it is essential to prepare a feasible printing composition to gain a printable form of zinc oxide nanoparticles, which have good adhesion to the printing substrate. [..] Read more

Abstract: Bulk graphitic carbon nitride (g-C3N4) was prepared by heating of melamine at 600 oC for 2 hours. Thermogravimetric analysis showed that this temperature is optimal for the preparation of bulk g-C3N4 without unnecessary loss of the material. [..] Read more

Abstract: The graphitic carbon nitride (g-C3N4) samples were prepared by the three different methods: (i) heating of melamine at 600 ºC (bulk g-C3N4), (ii) exfoliation of bulk g-C3N4 by heating at 500 ºC (Ex500) and (iii) exfoliation of bulk g-C3N4 by ultrasonication in an aqueous dispersion (ExUltra). The exfoliation was performed to obtain g-C3N4 nanosheets or other nanostructures. [..] Read more

Abstract: Ghassoul [rasul], stevensite-rich clay from Morocco, was used as a component of electrically conducting polypyrrole/ghassoul and polyaniline/ghassoul nanocomposites with polymer:clay ratio 1:1. The nanocomposites in powder form were obtained by polymerization of pyrrole and anilinium sulfate, respectively, in aqueous suspension of ghassoul. [..] Read more
