Abstract: In this contribution, the deposition of tin oxide thin films and the resulting layer properties are investigated. An atmospheric pressure PECVD process using a non-thermal plasma jet was applied, creating the coatings on silicon and glass slides. [..] Read more

Abstract: The environmentally friendly preparation of silver nanoparticles was proposed for the production of antibacterial non-woven textile used in water filtration. The silver nanoparticles were prepared by chemical reduction of silver nitrate using two environmentally friendly reducing agents, such as fructose or ascorbic acid. [..] Read more

Abstract: This paper presents the synthesis and stabilization of Gold nanoparticles (Au NPs) using five different hydrocolloids [Tragacanth (Tg), Karaya (Kg), Guar (Gg), Carrageenan (Cg), and Xanthan (Xg)] via greener pathways. The particle size, morphology, stabilization characteristics and catalytic efficiencies of the synthesized Au NPs were analyzed using spectroscopic and microscopic techniques. [..] Read more

Abstract: Natural phyllosilicate montmorillonite (MMT) was intercalated by electrically conducting polymer polypyrrole in order to obtain nanocomposites with enhanced electrical conductivity and stability in comparison with pure polypyrrole (PPYR). Samples in powder form were prepared via oxidative polymerization of pyrrole in aqueous solution using FeCl3 as oxidizing agent. [..] Read more

Abstract: In this paper, we report the optimal conditions for the isolation of amino acid arginine from different types of matrix, such as blood, plasma or tissue and their characterization using ion-exchange liquid chromatography with VIS detector. Paramagnetic microparticles able to isolate and immobilize amino acid arginine were prepared and used to preconcentrate arginine for subsequent analysis on ion-exchange liquid chromatography with VIS detector.

This new nanocomposite has enhanced sorption properties and photocatalytic activity due to presence of g-C3N4. [..] Read more

Abstract: The topic of emission reduction and recycling in civil engineering is highly discussed topic over last years. With respect to construction waste production, it is obvious to reuse materials such as concrete. [..] Read more

Abstract: Fluorescence imaging is an efficient and powerful technique, which has been often utilized for tracking compounds in animals, however its application on plants or other organisms is not very common. In this work, the fluorescence imaging was used to investigate the effect of selected nanoparticles - NPs (ZnO, CdTe, etc.) on microalgae (Scenedesmus quadricauda and Chlorella vulgaris) growth.

Abstract: Static electricity on the surface of dielectric polymers can be dangerous in various areas of human life. Antistatic agents reduce or eliminate accumulation of static electricity by creation a conductive layer on the polymer surface. [..] Read more

Abstract: The magnetically modified composites for Cd(II), Pb(II) and Zn(II) ions removal from aqueous solution were synthetized. Montmorillonite/FexOy composites were successfully prepared using ferrofluid. [..] Read more

Abstract: Chlorinated solvents such as trichloroethene (TCE) are widespread groundwater contaminants. These contaminants can be transformed by combination of abiotic and biotic methods under anaerobic conditions. [..] Read more

Abstract: Bismuth iodate was prepared using a hydrothermal synthesis of Bi(NO3)3·5H2O and I2O5. The time effect of the hydrothermal synthesis (4, 24, 48 and 72 h) on the structure, specific surface area (SSA) and morphology of bismuth iodate particles, their optical properties and photodegradation activity were studied.

Abstract: Many paints contain special additives such as biocides which act as a prevention against biodeterioration. Presence of nanoparticles of silver and copper may inhibit the grow of microorganism. [..] Read more

Abstract: Diamond thin films and nanodiamond particles are considered promising for addressing the long-term challenge of organic photovoltaics: efficiency and stability. In this work, we characterize stability of surface potential and photovoltage on polyfunctional detonation nanodiamonds merged with polypyrrole oligomers. [..] Read more

Abstract: G-C3N4 is an intensively studied material for photocatalytic applications, mainly for the degradation of pollutants in water and air. The thermal polymerization of suitable precursors (urea, melamine, dicyanamide etc.) is the most often used approach for the g-C3N4 synthesis. [..] Read more

Abstract: In this paper we prepared flexible ammonia (NH3) gas sensor based on polyaniline (PAni) as an active sensing thin film layer. The sensors function was based on chemiresistive principle with thin film deposited on top of interdigitated electrodes. [..] Read more

Abstract: Anodization is a simple and effective method to synthesize self-organized titanium dioxide nanotubes. But depending on the electrolyte used for anodization, there is a disorder “nano grass” or an “initiation layer” on top of the nano tubes. [..] Read more

Abstract: Nanostructuring and morphological engineering are the two important aspects of the control of the performance of functional materials. In the present work, we report on the fabrication of high aspect discrete TiO2 nanotubes possessing two or multi-legs via electrochemical anodization of titanium foil. [..] Read more

Abstract: Technologies involving iron-based nanomaterials, such as nanoscale zero-valent iron (nZVI), are extensively used for elimination of various contaminants in the environment. In this study, we modified commercial nZVI particles NANOFER 25P (from NANO IRON company, CZ) via one-step thermal treatment under different conditions (including temperature, time, and atmosphere), in a way that has not been previously reported.
