Chemotaxis is the phenomenon in which cells direct their movements in the presence of certain chemicals (chemoattractants or chemorepellents). Leukocyte recruitment (via chemotaxis) is an important component of the inflammatory response, both in physiological host defense and in a range of prevalent disorders that inc…
We study nematic electrohydrodynamic convection (EHC) under excitation with superimposed harmonic wave forms. Within the standard model for EHC, a time reversal of the excitation does not affect threshold voltages and pattern wavelengths obtained in a linear stability analysis. This was confirmed in experiments with s…
The formation of a porous Cu structure from cast Al–Cu–Co decagonal quasicrystalline alloys has been studied using a selective corrosion technique. Two alkaline solutions were selected based on the electrochemical properties of the constituent elements. Selective corrosion of Al and Co was achieved by chemical immersi…
A set of precise measurements of UV-Vis absorption spectrum for the classical bent-shaped molecule, P-12-OPIMB, revealed that molecular exciton interactions exist even in the mesophases of this system, as manifested as an obvious and abrupt change in the positional and spectral shape at phase-transition points. Based…
This paper introduces a novel numerical approach, object-oriented finite element (OOF) technique, to incorporate the acquired nanocomposite morphological images into two-dimensional finite element modeling. The overall material behavior can be reasonably well understood combining real data from microstructures with th…
Gelatin was prepared from chicken feet skin of Broiler. Yield, moisture, ash content, pH value, fat content, protein content, viscosity and gel strength of the chicken feet skin were evaluated. A completely randomize factorial design was used, with two levels of broiler age (30 and 40 day) and tree levels of extractio…
High-frequency vibrations related with copper nanowires on a silicon substrate are studied using picosecond ultrasound spectroscopy. The reflectivity change in the probe light pulse is monitored after irradiation of the specimen with the ultrafast light pulse, showing high $(\ensuremath{\sim}75\text{ }\text{GHz})$ and…
Abstract The effect of poly( D , L ‐lactide‐ co ‐ para ‐dioxanone) (PLADO) as the compatibilizer on the properties of the blend of poly( para ‐dioxanone) (PPDO) and poly( D , L ‐lactide) (PDLLA) has been investigated. The 80/20 PPDO/PDLLA blends containing from 1% to 10% of random copolymer PLADO were prepared by solu…
We present the theory of the in-plane magnetoresistance in two-dimensional massless Dirac fermion systems including the Zeeman splitting and the electron-electron interaction effect on the Landau level broadening within a random phase approximation. With the decrease in temperature, we find a characteristic temperatur…
The title compound Ru(9)Zn(7)Sb(8) was synthesized via a high-temperature reaction from the elements in a stoichiometric ratio, and its structure was solved by a single-crystal X-ray diffraction method. The structure [cubic, space group Fm3m, Pearson symbol cF96, a = 11.9062(14) Å (293 K), and Z = 4] adopts a unique 2…
We present a numerical study of the spectral evolution of the linear polarization degree at right-angle scattering configuration ( P L (90°)) for two different particle systems: an isolated nanosphere and a nanodimer composed of two finite size spherical particles separated by a gap distance d . We shall focus on the…
Abstract A series of highly organosoluble polyamides with high modulus having propeller‐shaped triarylamine were synthesized using aromatic diacid chlorides by low‐temperature solution polycondensation. The polyamide films had strong, tough, flexible, and amorphous properties. These polymers revealed electrochromic ch…
This paper describes the formation of organic nanorods induced by monolayer-protected inorganic nanoparticles. Alkanes and alkane derivatives, such as n-carboxylic acids, self-assemble on highly oriented pyrolytic graphite (HOPG) into a persistent molecular packing structure that is dictated by the epitaxial interacti…
Gold nanoparticles (average size 1 nm) encapsulated inside cucurbit[7]uril exhibit, upon 532 nm excitation in water, an intense transient absorption spectrum. The temporal profiles of the signals were different depending on the monitoring wavelength and extended beyond 1.2 ms. Quenching experiments using electron dono…
Abstract This research was carried out to investigate on the effect of organomodified montmorillonite (OMMT) on the flame retarding characteristics and clay dispersion of composites based on high‐density polyethylene and rice husk flour. To meet this objective, the blend nanocomposites were prepared through the melt m…
Abstract A facile, electrically induced reversible gelation in a PAA aqueous solution containing Fe ions has been realized. The PAA solution is converted into a homogeneous hydrogel when the ferrous ions are electro‐oxidized to ferric ions and this gel is restored to solution by electro‐reduction of the ferric ions to…
This article is concerned withthe existence of traveling wave solutions, including standing waves,to some models based on configurational forces, describingrespectively the diffusionless phase transitions of solidmaterials, e.g., Steel, and phase transitions due to interfacemotion by interface diffusion, e.g., Sinteri…
This chapter describes method for evaluation of nanomaterial cytotoxicity by examining effects on porcine kidney (LLC-PK1) and human cancerous liver cells (Hep G2). Several studies indicate that many nanoparticles are cleared from the body through the kidney or liver, making these organs good choices for target organ…
The magnetization reversal of La 0.7 Sr 0.3 MnO 3 (LSMO) epitaxial films deposited on 10° vicinal SrTiO 3 (001) substrates has been investigated at room temperature by using longitudinal magneto-optical Kerr microscopy. In the case when the magnetic field is applied parallel to the substrate steps, magnetization rever…
The results of studies into the relationship 'methods and synthesis conditions of a catalyst→catalyst structure→catalytic properties' in highly efficient crystallo-graphically amorphous copper- and iron-containing heterogeneous systems obtained by different chemical methods are generalized. Polymorphism of active phas…
