Evaluation of the Combined Effect of Chitosan and Lactic Acid Bacteria inAlheira(Fermented Meat Sausage) Paste
This study aimed to assess the efficacy of chitosan, Pediococcus acidilactici HA-6111-2 (bacteriocinogenic strain with antilisterial activity) and Pediococcus pentosaceus HA-3083-3 (a nonbacteriocinogenic strain), added individually or in combination, in the control of Listeria innocua, Staphylococcus aureus, Escheric…
Linking dynamical heterogeneity to static amorphous order
Glass-forming liquids grow dramatically sluggish upon cooling. This slowdown has long been thought to be accompanied by a growing correlation length. Characteristic dynamical and static length scales, however, have been observed to grow at different rates, which perplexes the relationship between the two and with the…
Diamond magnetometry of Meissner currents in a superconducting film
We study magnetic field penetration into a thin film made of a superconducting niobium. Imaging of magnetic field is performed by optically detecting magnetic resonances of negatively charged nitrogen-vacancy defects inside a single crystal diamond, which is attached to the niobium film under study. The experimental r…
Electronic and Magnetic Properties of Ca-Doped Mn-Ferrite
Spinel ferrite structures have vast applications, from microwave to radio frequencies. In order to acquire new electronic and optical behavior, divalent cations can be added to normal spinel ferrite structure. This way it is possible to facilitate its usage in material and science technology. In this work we have anal…
Acid-base and adsorption properties of the AlOOH 2D nanostructures as factors for regulating parameters of model biological solutions
We have studied the acid-base, adsorption, and electrokinetic properties of 2D nanostructures—agglomerates of pseudoboehmite (AlOOH) nanosheets 2–5 nm in thickness—that were synthesized from electro-explosive Al/AlN nanopowder. By the example of adsorption of anionic dye eosin and cationic dye methylene blue, it is fo…
Protection of 6061 Al-15%(v) SiC(P) composite from corrosion by a biopolymer and surface morphology studies
The protective action of biopolymer starch on 6061 Al-15% (v) SiC (P) composite in 0.25 M hydrochloric acid was studied by potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques with temperature ranging from 303 to 323 K. The concentrations of starch used were in the range of 0.…
Isolation design of a 14.4kV, 100kHz transformer with a high isolation voltage (115kV)
In this paper, the isolation design procedure of a 14.4kV output voltage, 100kHz transformer with an isolation voltage of 115kV using Litz wire is presented. For designing the isolation, a comprehensive design method based on an analytical maximum electrical field evaluation and an electrical field conform design is u…
Use of solutions of radiation-synthesized telomers of tetrafluoroethylene to modify glass fiber
In this work, we have suggested a new approach to fabricating fluorine-containing glass fibers based on the infiltration of glass-fiber filler by radiation-synthesized telomer solutions of tetrafluoroethylene. The radiation-chemical synthesis of tetrafluoroethylene telomers has been carried out in some solvents, their…
Behaviors of Zn 2 GeO 4 under high pressure and high temperature
The structural stability of Zn 2 GeO 4 was investigated by in-situ synchrotron radiation angle dispersive x-ray diffraction. The pressure-induced amorphization is observed up to 10 GPa at room temperature. The high-pressure and high-temperature sintering experiments and the Raman spectrum measurement firstly were perf…
Fabrication and Characterization of Zinc Sulfide Nanoparticles and Nanocomposites Prepared via a Simple Chemical Precipitation Method
In this research zinc sulfide (ZnS) nanoparticles and nanocomposites powders were prepared by chemical precipitation method using zinc acetate and various sulfur sources. The ZnS nanoparticles were characterized by X-ray diffraction, scanning electron microscopy, ultraviolet-visible and fourier transform infra-red. Th…
The effect of size of the SiC inclusions in the AlN–SiC composite structure on its electrophysical properties
AlN–SiC–Y 3 Al 5 O 12 composite materials with a high absorption of microwave frequency (27–65 dB/cm) produced by pressureless sintering of mixtures consisting of AlN(2H), Y 2 O 3 , and SiC (6H) in 46, 4, 50 wt %, respectively, have been studied. The SiC components of the mixtures were used in sizes of 1, 5, and 50 μm…
Corrosion resistance and adhesion of poly(L-lactic acid)/MgF2 composite coating on AZ31 magnesium alloy for biomedical application
Fluoride conversion layer was produced on AZ31 magnesium alloy by soaking in hydrofluoric acid solution and poly(L-lactic acid) (PLLA) film was prepared by spin-coating the PLLA solution. The as-prepared samples were comparatively characterized in phase structure, elements profile, morphology, adhesion force, and corr…
Possibility of adjusting photoluminescence spectra of Ca scheelites (CaMoO4: Eu3+ and CaWO4: Eu3+) to the emission spectrum of incandescent lamps
The peculiarities of the photoluminescence of compounds CaMoO 4 : Eu 3+ and CaWO 4 : Eu 3+ with the scheelite structure associated with a change in the short- and long-range orders of the crystal lattice upon a change in the activator (Eu 3+ ) of the photoluminescence range in the interval 1–4 mol %, in which the phot…
Verification of the T–x–y diagram of the Ag–Au–Bi system using a 3D computer model
Using two variants (with and without decomposition of the compound Au 2 Bi) of a 3D computer model of the T–x–y diagram of the system Ag–Au–Bi, it was shown that the published polythermal sections (both experimental and calculated by the CALPHAD method) agree in the high-temperature range of the T–x–y diagram for phas…
Adsorption of n-butane on graphene/Ru(0001)—A molecular beam scattering study
Adsorption kinetics/dynamics of n-butane on graphene, physical vapor deposited on Ru(0001) (hereafter G/Ru), and bare Ru(0001) (hereafter Ru) are discussed. The chemical activity of the supported-graphene as well as the support was probed by thermal desorption spectroscopy (adsorption kinetics). In addition and to the…
The potential energy landscape for crystallisation of a Lennard-Jones fluid
Crystallisation pathways are explored by direct analysis of the potential energy landscape for a system of Lennard-Jones particles with periodic boundary conditions. A database of minima and transition states linking liquid and crystalline states is constructed using discrete path sampling and the entire potential ene…
