Abstract We have discussed the percolation‐like insulator–metal transition, the conduction mechanism, and localization of photo‐induced magnetic solitons with the hole in the perovskite PrCaMnO by using quantized massive gauge fields, which are introduced theoretically in the path‐integral method, around the photohole.
Abstract To describe and predict the crystallization and morphology evolution of semicrystalline polymers, the shape of crystals is often modeled as spheres and/or cylinders. The Kolmogoroff–Avrami model, which is often used to model the crystallinity and spherulite growth of polymer materials under isothermal and non…
Abstract In the present study, the fracture properties of different types of organophilic montmorillonite (OMMT) filled polyamide 6/polypropylene nanocomposites was investigated. Two types of compatibilizers, i.e., maleic anhydride grafted polypropylene (PP‐g‐MA) and maleic anhydride grafted styrene‐ethylene/butylene‐…
We report upon the wetting property of layers of a micropatterned photodefinable silicon elastomer, PDSE, repetitively and alternatively treated with oxygen plasma and temperature cycles. At low power plasma treatments, we observed a hysteresis in terms of contact angle between phases lowering the contact angle and ph…
Polycrystalline tin-doped indium oxide (ITO) films were deposited at growth rates up to 0.8 nm/s on glass using pulsed nebulization CVD. The precursor solutions were nebulized into droplets with a modal size significantly smaller than predicted by theory. Rhombohedral distortion of the structure was observed in a numb…
Technological applications of discotic nematogens are limited by the robustness of the columnar phases. This investigation employs Monte Carlo simulations to explore the potentiality of tailoring specific interactions of either stacking or peripheral type in order to enhance nematic stability. It is concluded that the…
We studied the stability of single-walled carbon nanotubes (SWNTs) and double-walled carbon nanotubes (DWNTs) films as a function of surface modification. Conductivity measurements disclosed that gold ion and HNO 3 treatment of the nanotube network films increased the electrical conductivity by more than a factor of 2…
We present a study of morphology of graphene nanoribbons with armchair edges placed on the SiC(0001) substrates. We found that on the Si-terminated SiC(0001) surface the initial planar shape of a graphene nanoribbon can be substantially distorted by the underlying substrate. Appreciable ripples are created in the grap…
Abstract A blend of two biodegradable and semi‐crystalline polymers, poly (L‐lactic acid) (PLLA; 70 wt%) and poly (butylene succinate‐co‐L‐lactate) (PBSL; 30 wt%), was prepared in the presence of various polyethylene oxide‐polypropylene oxide‐polyethylene oxide (PEO‐PPO‐PEO) triblock copolymer contents (0.5, 1, 2 wt%)…
WS2 nanotubes have been filled and intercalated by molten phase caesium iodide. The presence of caesium iodide inside the WS2 nanotubes has been determined using high-resolution transmission electron microscopy (HRTEM) coupled with electron energy-loss spectroscopy (EELS) and energy-dispersive X-ray spectroscopy (EDS)…
Based on first-principles calculations, we show that the abundant ${\text{Cu}}_{\text{Ca}}$ antisite defect contributes sizably to dielectric screening in single-crystal ${\text{CaCu}}_{3}{\text{Ti}}_{4}{\text{O}}_{12}$. ${\text{Cu}}_{\text{Ca}}$ has a multi-minimum off-center equilibrium configuration, whereby it pos…
Abstract The effects of the amounts of starch, sodium acrylate (NaAA) and dicumyl peroxide (DCP) on the properties of chloroprene rubber (CR)/starch/NaAA composites prepared by melting method were investigated. The results showed that the addition of starch improved the mechanical properties, but decreased the water‐a…
No evidence of long-range spin ordering or spin glass behavior was found in well-processed Mn-doped KTaO3. If the magnetic anomaly is detected it is of an extrinsic nature from Mn clustering inside the KTaO3 lattice or Mn-oxide precipitates. Incomplete processing results in an antiferromagnetic response due to a prese…
The new compound Cs(10)P(8)Se(20) features the heterotetracyclic [P(3)Se(7)](3-) anion, a phosphorus-rich four-membered-ring species that possesses a P-P-P unit and formally P(3+) and P(4+) centers. It crystallizes in the orthorhombic space group Pnnm with a = 26.5456(7) A, b = 8.0254(2) A, c = 11.9031(4) A, and Z = 2…
A series of 1,4-polybutadienes of varying molecular weight, both monodisperse and having broad or bidisperse molecular weight distributions, were studied using dielectric relaxation. The glass transition temperature, T g, and the T g -normalized temperature dependence of the segmental relaxation times, τ α, varied mon…
It is well-known that the applications of nanoparticles are highly dependent on their size-related physical and chemical properties. Size fractionation, therefore, is important for the successful application of nanoparticles. In this study, we present a method for the size fractionation of gold nanoparticles (Au-nps)…
The simultaneous sputtering of ZnO and Ga2O3 by electron cyclotron resonance and rf magnetron plasma sources produced Ga-doped ZnO (GZO) films with continuously varying Ga concentration over the substrate surface. Combinatorial evaluation of electrical and optical properties of GZO film grown on silica glass substrate…
The representative isodesmic reactions shown in the Abstract graphic for (CH)(4)X(6) hexaheteroadamantane derivatives reveal energetic nonadditivity to remarkably different extents: while the electropositive element stabilizations are exceptionally large and the pnictide and hexaoxaadamantane stabilizations are more m…
Abstract The first example of a heteropolyoxomolybdate containing palladium(IV) was isolated and characterized by X‐ray crystallography. The palladium(IV) hexamolybdate, K0.75Na3.75[PdMo6O24H3.5]·17H2O, was isolated from an aqueous solution at pH 4.5 in the space group P\bar{1}, a 10.790(2), b 12.244(3), c 14.086(3) Å…
A two-band model that includes edge interactions is derived for hydrogen-terminated, armchair-edge graphene nanoribbons. This model is then used to obtain analytical expressions for the localization length of these ribbons in the presence of environmental and topological edge disorder. Within the single-channel regime…
