Abstract: That article is focused on the biocidal effect of nanofiber textiles based PVA enriched by agents with potential (copper, diamond and biocide) to limit the growth of consortium consists of algae and bacteria. It was proved that the basic PVA (solution and nanofiber textiles) has not any effect against the growth. [..] Read more

Abstract: A soil in region of Czech Republic and Austria is continuously losing its natural property to retain water in its structure. Most of the water which comes from rains just goes through the soil into the groundwater and agricultural lands suffer by the lack of humidity. [..] Read more

Abstract: An understanding of machining process fluids (types, compositions, operational conditions, lubricating and cleaning effect) is important for maximizing machining process efficiency by reducing heat generation, improving surface roughness, stabilizing the machining process, and increasing the operating life. Contamination by bacteria or even fungi is the weak point of these liquids. [..] Read more

Abstract: Nano-sized iron oxide particles such as maghemite γ-Fe2O3, hematite α-Fe2O3 and magnetite Fe3O4 are well known for their multiple applications such as; medicine, catalysis, sensors, memory devices and electronics. In photocatalytic properties, these particles play important role as holder for photocatalytic compounds, such as co-dopped TiO2. [..] Read more

Abstract: The paper focuses on the problematic of coaxial electrospinning with a wire spinning electrode. Despite the wide usage of wire spinner in the industrial sector, only basic research has been made in the field of possible coaxial technology application. [..] Read more

Abstract: Today, many scientists study properties of nanofiber textiles. These properties are determined by the unique structure of nanotextiles and, therefore, it is necessary to know exactly how the structure of the fabric looks like. [..] Read more

Abstract: The paper deals with verification of the mathematical model of electrospinning devices. The model enables to simulate the electric field strength and voltage with using the finite element method. [..] Read more

Abstract: Nowadays production of parallel structured nanofibers is widely evolving and is gaining popularity in various fields. This research is about the development of a modified device to produce nanofiber yarn with high quality oriented fibers. [..] Read more

Abstract: High-voltage nanoporous anodic films grown on aluminium in certain organic electrolytes are of increasing interest for potential applications as nanotemplates to electrical capacitors and, more generally, as models for investigating self-organized growth of anodic oxides at the frontier conditions. The major difficulty associated with this technology is that the process of pore nucleation and growth over a large-area aluminium substrate needs optimization and adaptation to the specific technological conditions applied to aluminium substrates as the surface finishing pre-treatments.

Abstract: In the presented work, new composite nanomaterials, based on graphene oxide and styrene, have been developed for the retention purpose. 85Sr and 137Cs represent two of the main fission products being present in radioactive wastes from nuclear power cycle. [..] Read more

Abstract: Our research is focused on foliar fertilizers and their impacts on plant grow. These experiments are realized in agarose hydrogels (blank agarose hydrogels and agarose hydrogel with addition of potassium lignohumate). [..] Read more

Abstract: Plasma treatments were used to modify surface properties of polyethylene terephthalate (PET) and glass micro fibers, to improve their wettability. PET fibers, having diameter of 400 µm, and glass fibers (ø14 µm) were exposed to low pressure oxygen plasma. [..] Read more

Abstract: Attachment of organic molecules is usually accomplished through the thiol functionality, but it would be desirable to have alternatives. Herein we would like to report preparation of gold nanoparticles with diameter of a few nanometers and their modification by alkyl chains. [..] Read more

Abstract: High density polyethylene (HDPE) is often used industrial polymer because of its good mechanical properties as high flexibility and tensile strength, high chemical resistance, easy processing and low price. Low surface energy of HDPE causes its low adhesion to printings, coatings and adhesives, what limits its industrial use. [..] Read more

Abstract: TiO2 nanotubes are highly promising for application in various fields. Many publications are concerned with nanotubes prepared by the anodization of titanium foil. [..] Read more

Abstract: In this work, a new gas phase photocatalytic reduction system was designed to convert CO2 into fuels. The optimal conditions (such as humidity, initial concentration of CO2 and the placement of powder photocatalyst in the reactor) for CO2 photocatalytic reduction were systematically investigated with the commercial photocatalyst TiO2 Evonik P25 in the homemade gas phase reactor. [..] Read more

Abstract: Three different ordered mesoporous silica materials, such as MCM-41, Al containing MCM-41 (mass ratio Si/Al = 10) and SBA-15, were prepared. In a next step, cobalt (5-8 wt%) as an active metal for redox reactions, was introduced by the impregnation. [..] Read more

Abstract: Solid phase microextraction (SPME) has been established as a convenient method of sample preparation in organic analytical chemistry since its introduction by Pawliszyn in the nineties of the 20th century. Recently, first attempts are reported on the preparation of SPME sorbents by electrospun nanofibres, in contrast to routinely applied sol-gel techniques. [..] Read more

Abstract: We report on electrical and optical performance of InAs/AlSb/GaSb type-II superlattice photodetectors. The detector structure is designed to operate in the MWIR domain with a cut-off wavelength of 4.3 µm at 125 K. [..] Read more

Abstract: Membrane biofouling limits widespread using of membrane technology in different fields. Several ways how to restrict this negative effect and achieve improving in long-term membrane filtration performances have been tested so far. [..] Read more
