Dibutyl phthalate DBP and dioctyl phthalate DOP are the main components of the plasticizers. In order to investigate their molecular structure, chemical bond and spectrum, the geometrical parameters of the ground state and infrared (IR) spectrum are calculated using the density functional theory B3LYP method at the le…
Graphene represents a high-performance material for field effect transistor (FET) manufacture. As a monolayer of carbon atoms, graphene offers flexibility, high carrier mobility, and transparency. Solution-gated graphene FETs based on flexible substrates have been developed for various applications. However, none of t…
The objective of this work was to investigate the effect of different reaction temperatures on the mechanical and surface (interface) properties of calcium-carbonate (CaCO3)-filled bamboo fibers and polypropylene (PP) composites. With an ionic reaction of sodium carbonate and calcium chloride aqueous solution at vario…
The maximum sorption of water and its vapors is calculated using experimental data from calorimetric and effusion studies of flax, wood, and cotton cellulose. X-day diffraction is used to determine the crystallinity of cellulose samples. The equations relating crystallinity ( X ) with maximum sorption and the enthalpy…
The paper is devoted to modelling characteristics of ferromagnetic cores with the use of SPICE software. Some disadvantages of the selected literature models of such cores are discussed. A modified model of ferromagnetic cores taking into account the influence of temperature on the magnetizing characteristics and the…
A new class of polymer capsules with an in-built endocytic pH-coupled fluorescence switch is reported. These capsules display reversible "on/off" fluorescence in response to cellular pH variations. Using this system, the high-throughput quantification between surface-bound and internalized capsules is demonstrated. Th…
The emf (ɛ) dependence of C|Ag|AgI|glass Ag 2 GeS 3 | D |C galvanic elements on temperature is studied in the range of 470 to 575 K (C represents current electrodes, D denotes equilibrium three-phase alloys of individual Ag-Sb-Se systems, and AgI|glass Ag 2 GeS 3 is a bilayer membrane with purely ionic (Ag + ) electro…
In this work an image-based multiresolution sensor for online prediction of crystal size distribution (CSD) is proposed. The mean and standard deviation of log-normal probability density function as the CSD can be predicted through the online sensor. In the proposed approach, texture analysis of fractal dimension (FD)…
For wood particle-based composite panels, particle size distribution and morphology are classified as crucial factors for the industrial production process and the resulting product properties.However, fiber quality control for medium-density fiberboard (MDF) production is still just done on a low technical level beca…
We present a first-principles study of small clusters of LiBH 4 supported on graphene sheets in order to address the experimentally observed effects of the nanoconfinement of LiBH 4 in hard carbon nanoframeworks prepared from low-temperature pyrolysis of phenolic resins, where a fullerene-related structure with signif…
The long-range surface structure of the dichalcogenide $\mathrm{Mo}{\mathrm{S}}_{2}$ is probed with nanometer-length spatial resolution using low-energy electron microscopy (LEEM) and microprobe low-energy electron diffraction (\ensuremath{\mu}-LEED). The quality of two differently prepared types of $\mathrm{Mo}{\math…
Studies aimed at improving the tensile, flexural, impact, thermal, and physical characteristics of wood–plastic composites composed of Paulownia wood flour derived from 36-month-old trees blended with polypropylene were conducted. Composites of 25% and 40% w/w of Paulownia wood were produced by twin-screw compounding…
Manganese nitrides thin films on MgO (100) substrates with and without Cu-doping have been fabricated by plasma assisted molecular beam epitaxy. Antiperovskite compounds Mn3.6Cu0.4N have been grown in the case of Cu-doping, and the pure Mn3N2 single crystal has been obtained without Cu-doping. The Mn3.6Cu0.4N exhibits…
A fractional crystallization method was used to separate the cis and trans isomers of three double-decker silsesquioxanes (DDSQs) with an aminophenyl moiety in a THF + hexanes solvent mixture. The experimental solubilities were fitted to the Schröder–van Laar equation with activity coefficients determined using the NR…
Image potential states (IPSs) on monolayer, bilayer, and trilayer graphene epitaxially grown on SiC(0001) have been studied by time- and angle-resolved two-photon photoemission (2PPE) spectroscopy. The free-electron-like dispersions of even and odd symmetry IPSs with a quantum number of $n$ = 1${}^{+}$, 1${}^{\ensurem…
Recently, the mode splitting of B1+E in PbTiO3-related heterostructures has been attracted wide range of attention because it is considered to represent intrinsic stress in the materials. However, the spectral behaviour of B1+E mods had remained unclear even in the bulk crystal, i.e., they had been often designated as…
Nanodiscs are self-assembled discoidal nanoparticles composed of amphiphilic α-helical scaffold proteins or peptides that wrap themselves around the circumference of a lipid bilayer in a beltlike manner. In this study, an amphiphilic helical peptide that mimics helix 10 of human apoA-I was newly synthesized by solid p…
Metal oxide nanoparticles of TiO2 and ZnO were synthesised using mild hydrothermal solution routes (T = 150–180°C, P = autogeneous, in about 2–16 h) and selectively doped with (Ag+, Sn4+, Sb3+, In3+ = 1–5 M%) in the presence of hexylamine as additive or n-hexanol as surface modifier for tuning the band gap. The synthe…
Nanoporous gold (NPG) structures have useful applications based on their unique physical and chemical properties; therefore, the development of NPG preparation methods is the subject of extensive research. Recently, the anodization of Au surfaces was suggested as an efficient method for preparing porous Au structures.…
The nanocomposite of hard (BaFe12O19)/soft ferrite was prepared, and then the polypyrrole (PPy)–BaFe12O19/Fe3O4 multi core–shell was produced by in situ polymerisation method. X-ray diffraction, transmission electron microscope, scanning electron microscopy and fourier transform infrared spectroscopy analysis indicate…
