Abstract: Many theories are currently being accepted as possible explanations for the origins of life on early Earth (e.g. Metabolism-first world, Zinc world, Thioester world, RNA world and others). [..] Read more

Abstract: Protein edestin extraction from hemp seed press cakes obtained after a cold press oil extraction process has been optimized at laboratory scale and verified in a pilot plant experiment. Subsequent water and brine extraction of the disintegrated hemp seed press cake was used to obtain the water-soluble albumin protein fraction and the brine-soluble globulin fraction - edestin.

Abstract: We present a novel approach for deposition of metallic silver films from silver nitrate (AgNO3) ink. The conversion of AgNO3 is induced by argon plasma of the diffuse coplanar surface barrier discharge (DCSBD) generated at atmospheric pressure. [..] Read more

Abstract: We investigate how the geometry of nanovoids present during the (sub)nanosecond electrical breakdown in liquid water influences the electron multiplication. Our analysis uses a particle-tracing Monte Carlo simulation toolkit Geant4-DNA. [..] Read more

Abstract: A comparative study is reported for electrodeposited copper(I) thiocyanate layers (ca. 500 nm) on two types of conductive/semiconductive substrates; i) carbon (boron-doped diamond_BDD, glass-like carbon_GC), and ii) carbon-free F-doped SnO2 conducting glass (FTO). [..] Read more

Abstract: Water is often used as a medium for preparation of nanoparticles in plasma. One way to obtain plasma in liquids is a nanosecond high voltage pulse applied on micrometer sharp electrode, so that the electric discharge is developed. [..] Read more

Abstract: The article deals with the production of nanofibers using the AC-electrospinning method. It focuses on research into the possibility of eliminating the formation of fibers, which are not desirable. [..] Read more

Abstract: The main scope of work is to verify the possibility of production diverse fibres, which have different fineness and are produced simultaneously on one electrode. In the first phase of the research, a basic design of the geometry of the two-stage electrode was performed and subsequently, using FEM software, an analysis was performed to determine the electrical field at the individual stages of the electrode.

Abstract: Synthetic crystalline materials of the garnet group are used as scintillators in scanning electron microscopy. If a thick conductive layer is applied on the garnet surface, slower electrons don’t have enough energy to pass through this relatively thick conductive layer on the scintillator surface.

Abstract: Noble metal nanoparticles are excellent catalysts for many industrial important reactions. Because heterogenous catalysis is dependent strongly on the surface of catalyst the nanomaterials are better catalysts in comparison with the bulk materials. [..] Read more

Abstract: Chars and carbon membranes were prepared from fresh and smoked cigarette filters, and used as adsorbents for clofibric acid removal. Carbonization of cigarette filters took place at 650, 750 and 900 °C, whereas membranes were synthesized by filter dissolution in acetone, using NaCl (porogen) and glycerol (plasticizer).

Abstract: Interaction between polyelectrolyte and oppositely charged surfactant leads to a formation of a hydrogel with micellar nanodomains. The main focus of this work was to monitor and study how pH and its changes affect mainly mechanical properties of phase-separated hydrogels with micellar nanodomains. [..] Read more

Abstract: Materials with immobilized or entrapped nanoparticles are of considerable interest. Sulphur as one of the abundant elements on earth is cheap and environmentally friendly. [..] Read more

Abstract: Metal nanoparticles find wide application potential in the biological research due to their unique optical, magnetic, electrical properties. Utilization of the nanoparticles prepared by chemical synthesis for biological research is limited by its solubility in water and toxicity. [..] Read more

Abstract: Interactions between tricyclic antidepressants and zinc oxide nanoparticles have been studied. Amitriptyline and nortriptyline, which were immobilized from buffer medium at 37 °C, were selected as models. [..] Read more

Abstract: Because of unique optical properties and easy complexation with biopolymers, gold nanoparticles (GNPs) are actively used as markers in various analytical systems, in particular, as components of conjugates with antibodies in rapid immunochromatographic test systems (ICTSs). However, the choice of the most effective conjugates is often empirical. [..] Read more

Abstract: The mechanical and biomechanical properties of the cell's extracellular matrix is a factor in their later development. In this regard, elastic biocompatible materials as a surface for cultivating cells are in recent years, becoming an exciting field of study. [..] Read more

Abstract: Atomic force microscopy (AFM) is a highly sensitive non-invasive surface method able to provide insight into cells' mechanical parameters. Membrane and sub-membrane development, as well as internal cellular properties, can be monitored. [..] Read more

Abstract: The aim of this study was to prepare an antibacterial nanofibrous membrane using electrospinning technique. The nanofibrous membranes were spun from polymer solution of poly(vinylidne fluoride)-co-hexafluoropropylene (PVDF-co-HFP) dissolved in N,N´-dimethylformamide. [..] Read more

Abstract: Nowadays, the rapid identification of bacterial antibiotic resistance is one of the major biomedical challenges. Classical methods of detection (culture and sensitivity testing, microbial whole-genome sequencing) fail in the context of time requirements. [..] Read more
