Dense Ni0.37Cu0.20Zn0.43Fe1.92O3.88/BaFe0.5Nb0.5O3 composites were prepared by the conventional solid-state method and sintered at 950°C. The powder x-ray diffraction (XRD) patterns confirm the coexistence of the two phases. The dielectric and magnetic properties are also reported. The results show that the as-prepare…
Macroscopic deformation and failure modes of polyolefines are reviewed in terms of deformation and failure models based on the craze initiation and propagation model of Kramer–Berger and the craze–crack transition model of Kramer–Brown. Although these models were formulated for amorphous polymers they are also valid f…
Abstract Single crystals of a novel solid-solution compound BaMoxTi1−xO3 (x ≈ 0.175) in a BaTiO3 and BaMoO3 system were successfully grown by flux in Ar at 1423 K using the BaCO3–B2O3 system flux. The obtained crystals were black and rectangular with a maximum dimension of 0.2 × 0.2 × 0.3 mm3. The EDX and EPMA analyse…
The sucCD gene of Advenella mimigardefordensis strain DPN7(T) encodes a succinyl coenzyme A (succinyl-CoA) synthetase homologue (EC 6.2.1.4 or EC 6.2.1.5) that recognizes, in addition to succinate, the structural analogues 3-sulfinopropionate (3SP) and itaconate as substrates. Accumulation of 3SP during 3,3'-dithiodip…
We consider nuclear spin dynamics in a two-electron double dot system near the intersection of the electron spin singlet $S$ and the lower energy component $T_{+}$ of the spin triplet. The electron spin interacts with nuclear spins and is influenced by the spin-orbit coupling. Our approach is based on a quantum descri…
In order to understand how electron effective mass is enhanced by anharmonic local oscillation of an atom in a cage composed of other atoms, i.e., {\it rattling}, we analyze anharmonic Holstein model by using a Green's function method. Due to the evaluation of an electron mass enhancement factor $Z$, we find that $Z$…
We suggest simple model of image formation in atomic force microscope (AFM) taking into account contact deformations of probe and sample during scanning. The model explains the possibility of AFM visualization of regular atomic or molecular structure when probe-sample contact area is greater than an area per atom or m…
The expanded biological and medical applications of nanomaterials place a premium on better understanding of the chemical and physical determinants of in vivo particles. Nanotechnology allows us to design a vast array of molecules with distinct chemical and biological characteristics, each with a specific size, charge…
Inspired by the simplicity and versatility of layer-by-layer (LbL) assembly, we applied multilayered polyelectrolyte assemblies on nanoparticles to create viable systemic delivery systems. Focusing on tumor-specific delivery, LbL nanoparticles that exhibit a pH-sensitive outer stealth layer are demonstrated to target…
The mechanical characteristics and the infrared imaging of stress-induced martensite transformation developing in TiNi shape memory alloy (SMA) subjected to tension in various conditions with respect to the SMA austenite finish parameter have been presented. Based on the mechanical curves and their related temperature…
A side-chain liquid crystalline polyurethane (LCPU) based on NCO- terminated polybutadiene and bi-phenol has been synthesized. The characterization of LCPU samples was done using gel permeation chromatography, scanning electron microscopy, differential scanning calorimetry, thermogravimetry, and polarized optical micr…
Abstract A simple‐cubic lattice of identical, magnetodielectric spheres exhibiting double‐negative (DNG) behavior is analyzed.An analytic expression for the threshold loss angle δ th of the spheres, above which DNG behavior is extinguished, is derived by utilizing the Möbius transformation. The formula is valid for ei…
Abstract Most of the recent research on electromagnetic absorbers at terahertz (THz) frequencies is focused on metamaterials based absorber, which provides high absorptivity of electromagnetic (em) radiations in narrow frequency band and tailoring of em response of materials. Under this work, we have also attempted th…
Rheological responses of hydrophobic fumed silica powders, whose surface silanol groups were modified by hexadecane, suspended in 1,4-dioxane at lower silica concentrations than 6.8 vol% have been investigated as a function of the silica concentration. Transient shear stress behavior before attaining the steady-state…
Cathodic current trends on stainless steel samples with different surface percentages covered by biofilm and potentiostatically polarized in natural seawater were studied under oxygen concentration changes, temperature increases, and additions of enzymic inhibitors to the solution. The results showed that on each surf…
This report describes an investigation into the generation of fiber length distributional function using a limited number of length measurements. Based on the experimental data, the correlation between fiber length statistics (the calculated mean value and variance) and length measures (tested short fiber content, spa…
We report on a $c$-axis polarized optical measurement on a Ba${}_{0.67}$K${}_{0.33}$Fe${}_{2}$As${}_{2}$ single crystal. We find that the $c$-axis optical response is significantly different from that of high-${T}_{c}$ cuprates. The experiments reveal an anisotropic three-dimensional (3D) optical response with the abs…
A special cavity based on effective near-zero-index paired structures containing ɛ-negative and μ-negative materials is realized by using composite right- or left-handed transmission lines. When an artificial magnetic "atom" is put into the cavity, unusual Rabi-type splitting appears because of the strong coupling bet…
Nonlinear optical imaging is a powerful method for observing bulk and interfacial phenomena in time and space. Here, we present a step-by-step description of how to carry out second harmonic generation imaging with a kHz amplifier laser system and demonstrate its applicability for SHG microscopy studies of highly size…
Two high molecular weight (MW) isotactic polypropylene (i-PP) samples, one containing a small amount of rr stereodefects denoted R1 and one conventional, commercial i-PP denoted S1, were used to grow single crystals in thin films at high temperatures ( T x = 145 °C for R1, T x = 155 °C for S1). Elongated α 2 -form lat…
