CdSe nanocrystals are intercalated into ordered hexagonal arrays of mesoporous silica. The nanocrystals are clearly confined in the channels and their size was estimated to be consistent with the pore size. Transmission electron microscopy suggests that CdSe nanocrystals have a spherical morphology and are stabilized…
Scaling laws for magnetic minor hysteresis loops that are asymmetric and have their origin at an arbitrary point under a bias field have been examined for Fe single crystals with tensile deformation. We found that there exist power-law relations between field-dependent parameters of asymmetrical minor loops, which are…
Simulation results for head-on collisions of equal-sized spherical polymer nanodroplets using molecular dynamics are presented. Elastic behavior of an initial compressed phase for the colliding droplets is analyzed. Deformations and contact radii of the nanodroplets are compared with the Hertzian model of elastic soli…
Abstract Tissue engineering involves the fabrication of three‐dimensional scaffolds to support cellular in‐growth and proliferation. Ideally, the scaffolds should be similar to the native extracellular matrix (ECM). Electrospun polymer nanofibrous scaffolds are appropriate candidates for ECM mimetic materials since th…
Measurements of specific heat of the electron-doped La0.2Ca0.8MnO3 manganite are reported for 2<T<400 K. It was found that La0.2Ca0.8MnO3 exhibits an orbital ordering at TOO=204 K and a long-range antiferromagnetic order below TN=178 K. The entropy changes (ΔS) around both TOO[ΔS(TOO)≈0.38 J/mol K] and T…
Titanium alloy has properties like outstanding corrosion resistance and very good biocompatibility whicht makes this material very interesting for biomedical applications. Due to its material properties titanium alloy poses a challenge for machining operations. A sound understanding of the alloy behaviour during the m…
We have investigated the temperature dependences of the line shape, spin-lattice relaxation time, T1, and spin-spin relaxation time, T2, of the H1 and L7i nuclei in K4LiH3(SO4)4 and (NH4)4LiH3(SO4)4 single crystals. We compared the nuclear magnetic resonance (NMR) results obtained for the two crystals. According to th…
The rates and magnitudes of vibrational energy transfer between single-wall carbon nanotubes (CNTs) and water are investigated by classical molecular dynamics. The interactions between the CNT and solvent confined inside of the tube, the CNT and solvent surrounding the tube, as well as the solvent inside and outside o…
The influence of the surrounding gaseous media on optically excited fluorescence of YAG:Ce nanoparticles was studied. It was observed that the 5d→4f fluorescence of Ce3+ ions in YAG nanoparticles dramatically depends on the pressure of the gaseous media surrounding the powder samples. The observations suggest the poss…
We present magnetic susceptibility, $^{1}\text{H}$ nuclear magnetic resonance (NMR) spectra, spin-spin- and spin-lattice-relaxation rates data, collected in the temperature range $1.65<T<300\text{ }\text{K}$ at two applied magnetic fields $H=0.35$ and 1.5 T, on a single crystal of ${\text{Cr}}_{7}\text{Fe}$ hete…
We have examined the effects of radial deformation and transfer doping on the electronic properties of an armchair single-walled carbon nanotube (SWNT) adsorbed on the gold (Au) and silver (Ag) surfaces. Using a semiempirical method developed on the basis of the continuum elastic shell model, it is found that the radi…
In the present work, the time sequence of blood activation by alumina membranes with different porosities (20 and 200 nm in diameter) was studied. The membranes were incubated with whole blood from 2 min to 4 h. Platelet adhesion and activation in addition to complement activation was monitored at different time point…
Abstract More than 2 decades of active investigations in the field of polymer brushes have revealed continuous and growing interest in different aspects of synthesis, properties, and applications of tethered polymers. In this article, we report on our recent advances in brush synthesis. The method we explore is based…
Co-microencapsulated ammonium polyphosphate and pentaerythritol [M(A&P)] was prepared using a hydroxyl silicone oil by in situ polymerization method, and characterized by X-ray photoelectron spectroscopy. The flame-retardant effect of M(A&P) in polypropylene (PP) is evaluated using limiting oxygen index, UL 94…
A focused laser beam irradiating on aligned carbon nanotubes (CNTs) in moderate vacuum results in bright and sustained laser-induced incandescence (LII) in CNTs. The incandescence corresponds to blackbody radiation from laser-heated CNTs at ∼2400 K. Post-LII craters with well-defined ring boundaries in the CNT array w…
Abstract The purpose of this article is to present a multiscale finite element method that captures nanoscale surface stress effects on the dynamic mechanical behavior of nanomaterials. The method is based upon arguments from crystal elasticity, i.e. the Cauchy–Born rule, but significantly extends the capability of th…
Abstract Electrospinning is a route to polymer fibres with diameters considerably smaller than available from most fibre‐producing techniques. We explore the use of a low molecular weight compound as an effective control additive during the electrospinning of poly(ε‐caprolactone). This approach extends the control var…
In this work we study the influence of manganese doping on the electromechanical properties of PZN–12%PT single crystal. The full electromechanical tensor of doped PZN–12%PT in the tetragonal single domain state is determined by the resonance-antiresonance method. Doping leads to a decrease in the dielectric transvers…
Abstract We have studied the adsorption of end‐attaching block copolymer chains inside the cylindrical pores of nanoporous alumina. Highly asymmetric PS‐PEO block copolymers, with a small PEO anchoring block and a long PS dangling block, were allowed to adsorb onto porous alumina substrates with an average pore diamet…
