Computer modeling and simulation for 3D isothermal crystallization of polymers is presented. We use the pixel coloring method to capture the morphology evolution and calculate the crystallization kinetics. A parametric study is used to explore the influences of nucleation density and growth rate on the crystallization…
Homogeneous dispersion of high-density polyethylene (HDPE)/ground tyre rubber (GTR) blends via solid-state mechanochemical milling was demonstrated here as a low-cost and industrially scalable method to prepare high-performance polymer blends consisting of recycled tyres, thereby providing a novel strategy for rubber…
Here we review the present state of structural and functional studies of the Sac10b protein family, a class of highly conserved 10 kDa nucleic acid-binding proteins in archaea. Based on biochemical and structural studies, these proteins were originally assigned a role in the structural organization of chromatin; Sac10…
The anionic polyurethane nanoparticles (APU-NPs) were obtained by an emulsion polymerization method. It was found that the average size of the prepared APU-NPs is about 84 nm, and the APU-NPs have zeta-potential of -38.9 mV. The bulk characterization of synthesized APU-NPs was investigated by FTIR. The blood compatibi…
Efficient wavelength converting nanophosphors are of high demand for their applications in energy conversion devices. We report on the synthesis of well dispersed LiAl5O8:Fe 3+ nanoparticles of homogeneous size and different morphologies by sol–gel method suitable for efficie t wavelength converting devices. Nanoparti…
Microstructure and magnetic properties of BiMnO3 and BiFe0.5Mn0.5O3 films, prepared by rf magnetron sputtering on LaAlO3 (001) single-crystalline substrate, are investigated. The selected-area electron diffraction analysis allows us to identify the crystal structure of the BiMnO3 film as orthorhombic, while the BiFe0.…
The stability of nano-scale ferroelectric domains in a LiNbO3 single crystal under varied atmospheric humidity levels was studied using piezoelectric force microscopy. Experimental results showed that the nano-scale domains fabricated by the tip field of the atomic force microscope changed as the environmental humidit…
Corrosion behaviours of the new type special commercial brass alloys, called 118 and MM55, have been investigated by Tafel Extrapolation (TP) and Linear Polarization (LP) methods in artificial seawater. Inhibition effect of benzotrizole (BTA) of four different concentrations for the corrosion of brass samples was inve…
Abstract The AJ62 magnesium alloy (Mg‐6Al‐2Sr) is characterized by good creep resistance up to 175°C and good castability enabling production of thin‐walled elements in die casting process. The aim of the work was to analyse the influence of hot‐chamber die casting parameters on the microstructure and mechanical prope…
We report the observation of room-temperature ferromagnetism in Cu-doped ZnO nanorods prepared by using a microwave irradiation technique. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results showed that Cu-doped ZnO had a single-phase nature with a wurtzite structure and that Cu ions had been su…
Chronopotentiometry and potentiodynamic voltammetry simulated were used to study the electrochemical behavior of the new pseudoelastic medical Ti-Nb-Ta alloy in simulated physiological media (neutral and acidified Hank’s solution, artificial saliva) at temperatures of 37 and 50°C as compared to titanium and nitinol. T…
We highlight the significance of capillary pressure in the directed assembly of nanorods in ordered arrays of colloidal particles. Specifically, we discuss mechanisms for the assembly of carbon nanotubes at the interstitial sites between latex polymer particles during composite film formation. Our study points to gene…
Electronic structures of five- and six-coordinate iron(III) corrolazine complexes are determined by means of 1 H NMR, 13 C NMR, EPR, and Mössbauer spectroscopy as well as SQUID magnetometry. A series of five-coordinate complexes, [Fe III (TBP 8 Cz)(L)]* where the axial ligands(L) are cyanide(CN - ), imidazole(HIm), 1-…
In this work, we suggest a method for microplasma synthesis of multicomponent iron-containing oxide coatings on the surface of aluminum alloys. For producing the coatings, we use a homogeneous electrolyte that contains iron in the form of its complexes with EDTA 4− and has a pH value of 9–10. The dynamics of the decre…
The outcome of protein crystallization attempts is often uncertain due to inherent features of the protein or to the crystallization process that are not fully under control of the experimentalist. The aim of this contribution is to propose user-friendly tools that can increase the success rate of a protein crytalliza…
Surfactant-mediated polyaniline (PANI) samples were fabricated using an electrodeposition technique for electrochemical supercapacitor applications. We investigated the effect of surfactants such as sodium dodecyl sulfate (SDS), polyvinyl alcohol (PVA), ethylenediaminetetraacetic acid (EDTA) on the PANI morphologies.…
The shape control inside a trenched 4H-SiC by atmospheric-pressure chlorine (Cl 2 ) etching has been investigated. The trench fabricated by a plasma process on the 4H-SiC(000 ) C-face with 4°-off toward [11 0] was used. The inside of the 4H-SiC trench was thermally etched in Cl 2 ambience at 900 °C. The subtrenches in…
In this pilot scale study, we examined the effects of alkaline extraction time on xylan removal, pulp and paper properties, and the consequences that need to be addressed when scaling up and intensifying the process. Alkaline extraction of bleached birch kraft pulp yields two fractions: pure polymeric xylan and pulp w…
This study is focused on the modification of wood fiber by using a reactive diisocyanate (toluene diisocyanate, TDI) linker to couple wood fiber with cetyl alcohol and the investigation of its effects on mechanical properties of wood fiber–HDPE composites. The reaction of TDI with wood fiber and then cetyl alcohol res…
Ferromagnetic resonance has been investigated in Ni2MnSn Heusler alloy lms. The lms were deposited at 673 < T < 723 K on MgO(001) substrates by means of magnetron sputtering. X-ray diraction conrmed that the lms were epitaxial. The lms had magnetic parameters typical of bulk Ni2MnSn with L21 structural order.
