The main purpose of modelling the yarn structure is to find relations that are more reliable giving the behaviour of the yarn starting from its components. In this paper, the identification of the mechanical behaviour of the elastic core spun yarns by a rheological modelling on the basis of pre-existent phenomenologic…
Abstract An unprecedented solvothermal treatment of triangular molybdenum oxo clusters K2[Mo3O4(Hnta)3] (1, nta = nitrilotriacetate) and H2bipy[Mo3O4(C2O4)3(H2O)3] (2, bipy = 4,4′‐bipyridine) was successfully established to prepare a series of new oligonuclear Mo(IV–VI) oxo clusters 3–5. Hydrothermal treatment of 1 in…
The effect of compounding procedure on morphology and crystallization behavior of isotactic polypropylene/high‐density polyethylene/carbon black (iPP/HDPE/CB) composite was investigated. iPP/HDPE/CB composites were prepared by four compounding procedures (A: iPP + HDPE + CB; B: iPP/HDPE + CB; C: HDPE/CB + iPP; D: iPP/…
An outstanding question in the physics of jammed packings concerns the nature of the correlations that arise near the unjamming transition. In this work, we study unjamming in an assembly of frictionless grains that are hard but not infinitely rigid. We demonstrate that a static correlation function, which probes sens…
Aims: Improvements in nanotechnology in the past decayed has created various opportunities for evaluation of biologic effects such as anti-bacterial effects of nanoparticles. The purpose of this study was to evaluate the antibacterial activity of calcium carbonate nanoparticles on two different bacteria including A gr…
Jute fabric-reinforced natural rubber (NR) based composites were produced by compression molding. Tensile strength (TS), tensile modulus (TM), elongation at break (Eb) bending strength (BS), bending modulus (BM), and softness of the composite were 30 MPa, 395 MPa, 65%, 10 MPa, 2130 MPa, and 79 Shore-A, respectively. D…
The crystal structures of three ternary Ni-Zn borides have been elucidated by means of X-ray single-crystal diffraction (XSC) and X-ray powder diffraction techniques (XPD) in combination with electron microprobe analyses (EMPA) defining the Ni/Zn ratio. Ni(21)Zn(2)B(24) crystallizes in a unique structure type (space g…
We theoretically calculate the charge-supercurrent through a ballistic graphene junction where superconductivity is induced via the proximity-effect. Both monolayer and bilayer graphene are considered, including the possibility of strain in the systems. We demonstrate that the supercurrent at the charge neutrality poi…
Abstract In order to enhance the grafting efficiency of graft copolymerization of granular cornstarch with acrylic acid (AA) for improving the adhesion and film properties of starch‐g‐poly(acrylic acid) used as sizing agent, the esterification of hydrolyzed starch with acryloyl chloride was applied before graft copoly…
The thermal stability of ZrB 2 ‐based composites containing SiC ‐chopped fibers was tested in a bottom‐up furnace at 1200°C, 1500°C, and 1700°C for 30 min. The oxidation behavior was studied by X ‐ray diffraction, scanning electron microscopy, and weight gain. The degradation induced by oxidation was also evaluated co…
Double-walled carbon nanotubes (DWCNTs) with outer metallic (M) or semiconducting (S) shells were sorted by density-gradient ultracentrifugation and examined by Raman spectroscopy and in situ Raman spectroelectrochemistry. The combination of sorting and the selection of appropriate laser excitation energies allowed th…
The aim of this study was to compare the electrochemical corrosion behaviour of stainless steel (SS) and nickel-titanium (Ni-Ti) orthodontic archwires in Ringer's solution at temperatures ranging from 15 to 55°C by using linear sweep voltametry and electrochemical impedance spectroscopy. Polarization curves show that…
Photochromic [Ru(bpy)(2)(OSO)](PF(6)), where bpy is 2,2'-bipyridine and OSO is 2-methylsulfinylbenzoate, was investigated by femtosecond transient absorption spectroscopy. The results show that for both S- and O-bonded isomers, a (3)MLCT state is formed on a femtosecond time scale. Also observed is the formation of mu…
Poloxamer-modified liposomes (PMLs) were prepared using poloxamers (P85 and F68) by the thin-film hydration method for overcoming the multidrug resistance and thereby enhancing the intracellular uptake of specific substrates of P-gp, rhodamine 123 (R123). The prepared liposomes, plain liposomes (PLs) and PMLs, were ch…
We report on the emergence of a Dirac point in the dispersion relation of a plasmonic metamaterial. It is realized as a three-dimensional crystal (cubic or orthorhombic) whose lattice sites are decorated by aggregates of gold nanoparticles embedded in a high-index dielectric material. The Dirac-type dispersion lines o…
We report $^{75}\mathrm{As}$ nuclear quadrupole resonance studies on $({\mathrm{Ca}}_{4}{\mathrm{Al}}_{2}{\mathrm{O}}_{6\ensuremath{-}y})({\mathrm{Fe}}_{2}{\mathrm{As}}_{2})$ with ${T}_{c}=27\text{ }\text{ }\mathrm{K}$. Measurement of nuclear-spin-relaxation rate $1/{T}_{1}$ has revealed a significant development of t…
Interfaces play an important role in bulk heterojunction organic/inorganic hybrid photovoltaic devices, but directly probing the interface in order to improve device characteristics is exceedingly difficult. We report on a method to form core-shell inorganic nanowire-polymer hybrids of a conducting polymer, poly(3-hex…
Abstract We have deposited p‐type hydrogenated amorphous silicon oxide (p‐a‐Si1‐xOx:H) by 13.56 MHz radio frequency plasma enhanced chemical vapor deposition (RF‐PECVD) using a gas mixture of silane (SiH4), hydrogen (H2), carbon dioxide (CO2) and diborane (B2H6). Optical and electrical characterization showed that hig…
Radical addition of ω-iodofluorinated telomers was used to modify silica (S 50 ) nanoparticles bearing vinyl groups. These iodo terminated derivatives were either commercially available tetrafluoroethylene telomers, C n F 2 n +1 I with n = 4 or 6, or vinylidene fluoride telomers, C n F 2 n +1 [VDF] m I with m = 6 and…
Abstract We present production of silicon nano‐particles and their surface nitridation for efficient multiple‐exciton generation. Nitridated silicon nano‐particles were produced using double multi‐hollow discharge plasma CVD, where generation of silicon particles and their nitridation were independently performed usin…
