Abstract: Here we report the optimal conditions for the isolation of reduced glutathione (GSH) and oxidized glutathione (GSSG) from various types of matrix, such as blood, plasma or cells and their characterization using ion-exchange liquid chromatography with VIS detector. In our study, we aimed to synthesize paramagnetic microparticles able to isolate and immobilize GSH, GSSG from blood or plasma and thus preconcentrate it for subsequent analysis on ion-exchange liquid chromatography with VIS detector.

Abstract: Zinc oxide nanorods as a potential material for nanoscale devices are prepared by chemical bath deposition (CBD). The effect of the quality of the sol-gel deposited seed layer on the vertical alignment of the nanorods to a silicon substrate is discussed. [..] Read more

Abstract: Self-combustion synthesis (SCS), a method of production of fine ceramic particles by burning suitable metallic precursors with organic fuel in a presence of an oxidizing agent, is an easy to use, high yield method, that, when mastered, can lead to production of significant amounts of nanoparticles with tuned properties and morphology. The method was used to prepare fine particles of iron oxide, cerium oxide, praseodymium oxide and various other lanthanide oxides with different organic fuels, including glycine, citric acid, ethylene glycol, urea and starch.

Abstract: Acrylic fibres can be used as a source of carbon structures. The reason is in chemical structure and thermal behaviour of acrylic polymer which is not melt-able and contains high quantity of carbon. [..] Read more

Abstract: Graphene-based materials show unique properties. These single layered materials consist of 2D structure of carbon atoms, belong to the strongest known materials, that are very mechanically flexible, optically transparent and that are excellent electrical and thermal conductors.

Abstract: The L21-structure Fe2AlTi intermetallic compound is one of the two phases identified in Fe-Al-Ti superalloy nanocomposites. Experimental data related to low-temperature magnetic properties of this Heusler compound indicate that magnetic moment is about 0.1 Bohr magneton per formula unit. [..] Read more

Abstract: Fe-Al-based nanocomposites with a superalloy-type of microstructure constitute a very promising class of materials. They possess a great potential as an alternative to the currently used steel grades in high temperature applications. [..] Read more

Abstract: This paper deals with the synthesis of silver nanoparticles (Ag NPs) under different reaction conditions, such as temperature and UV irradiation. We investigated how these variant parameters can affect the final properties of Ag NPs, mostly their size, shape and stability. [..] Read more

Abstract: A combination of electrospinning, a well-known technology for producing nanofibrous structures, and carbon nanotubes is presented in this work. Electrospinning is technology offering many arrangement options. [..] Read more

Abstract: We propose the sputtering deposition providing titanium thin films with controlled properties such as preferential crystallography and residual stress using Kaufman ion-beam source. The titanium thin films with thickness of ≈ 80 nm were deposited on [001] Si wafer covered by SiO2 deposited by plasma-enhanced chemical vapor deposition. [..] Read more

Abstract: P-I-N diode structures based on the thin films of amorphous hydrogenated silicon (a-Si:H) deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD) technique were prepared with embedded Si and Ge nanoparticles. The Reactive Laser Ablation (RLA) of germanium target was used to cover the intrinsic a-Si:H layer by Ge NPs under a low pressure of the silane. [..] Read more

Abstract: The Si-based submicro- and nanoparticles were prepared using a template sol-gel approach in the presence of cationic surfactants with different length of alkyl chains and alkaline catalysts that allowed a modulation of pore size and surface area of particles in the synthesis mixture to obtain materials with a wide range of size (25-1000 nm) and variable textural characteristics. Mesoporous materials were prepared with the aim to optimize and adapt different synthetic routs for further use of SP as reservoirs for carrying and advanced delivery of therapeutics..

Abstract: Preserving books for long-term is a challenging task and many methods have been used to prolong their lifespan. In this work, viscose fabric was used as the basis for an acrylic coating with two additives in the form of zinc oxide and dolomite nanoparticles. [..] Read more

Abstract: Reactivity and transport properties of metal ions are important both for evaluating and understanding role of humic acids in natural systems and human-driven applications as solving their structural questions. This paper focuses on metal ions diffusion and immobilization in humic hydrogels. [..] Read more

Abstract: Chlorinated ethenes (CEs) are the second most common contaminant worldwide. Remediation procedures combining treatment with nanoscale zero-valent iron (nZVI) and anaerobic microbial degradation supported by electric current belongs to one of the most successful approaches. [..] Read more

Abstract: The main goal of this work is to develop an effective method for biomass sampling to monitor the microbial diversity at contaminated sites.Within this work, various nanofiber carriers suitable for sampling of biomass and simultaneously for use in molecular-genetic analysis were developed. Two different shapes of a carrier with three different nanofiber densities (including carrier without nanofibers) were prepared and submerged into wells with different contamination (chlorinated aliphatic hydrocarbons and BTEX).

Abstract: The aim of this work was to investigate features of propane conversion in the presence of samarium, lanthanum, europium vanadate and samarium, lanthanum, europium vanadite. The conversion of propane was studied in the presence of samarium, lanthanum, europium vanadate and samarium, lanthanum, europium vanadite synthesized by solid-phase method. [..] Read more

Abstract: The environmental impact of the use of engineered nanoparticles (NPs) is undeniable based on many studies. Considering that NPs end up in wastewater treatment systems, the potential impact of selected NPs (TiO2, SiO2 or ZrO2) on the activated sludge, especially on Microthrix parvicella or Nocardia bacteria cells, was investigated using laboratory-scale batch reactors through short-term, 7-day exposure to 100, 200, 300 mg/L of NPs.

Abstract: In our investigations we prepared two different kinds of oxide coatings aiming for highly active photocatalytic properties and moreover deposition conditions, which could make them useful potentially also for temperature sensitive substrate materials. The first ones are titanium oxide thin films created by PECVD under atmospheric pressure conditions, Secondly, zinc oxide coatings were created by sol-gel technique via dip-coating. [..] Read more

Abstract: We set ourselves the task to perform a systematic study of the ortho–para conversion of protium catalyzed by γ-Al2O3-supported gold nanoparticles of various sizes at a temperature of 77 K. Our results unambiguously indicate that nanoparticles, as opposed to the bulk metal, shown a high catalytic activity. [..] Read more
