Four different dyes (Methyl red, Disperse red 1, 13 and 60) were separately doped to each of four different nematic liquid crystals (E7, E8, E63 and ZLI-1132). Their solubilities, textures, phase transition temperatures and order parameters were determined. At the second stage, single-walled nanotubes in a small amoun…
Both static and dynamic strain effects of La0.7Ce0.3MnO3 (LCeMO) thin films that were grown on (001) oriented SrTiO3 (STO) and 0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-PT) substrates were investigated. A charge-orbital ordering (COO) transition was found in the region of low temperature for strained (001)-LCeMO/STO films. T…
Abstract A new Ti‐6Al‐2Nb‐1Ta alloy was obtained for to satisfy the mechanical and anticorrosion requirements in neutral corrosive environment. The corrosion behaviour of this new Ti‐6Al‐2Nb‐1Ta alloy in 0.1 M Na 2 SO 4 , 3% NaCl solutions and synthetic sea water was studied in this paper, using potentiodynamic and li…
Abstract Coatings based on self‐assembled molecules (SAMs) for corrosion protection of aircraft aluminum alloys have been studied to evaluate their potentialities as replacements to yellow chromate conversion coatings (CCC), due to the toxicity of these leading to environmental problems. In this work, the influence of…
A detailed picture of the thermally activated processes occurring at the Co/ZnO interface is obtained by a combination of high energy X-ray based techniques: X-ray photoelectron and absorption spectroscopies and the kinematical X-ray standing wave method. At room temperature, the growth of a few monolayers of cobalt p…
In this article, Ag-SiO2 composite nanoparticles with a core-shell structure were prepared by a very simple and rapid wet chemical method in different solvents such as methanol, ethanol and isopropanol, respectively, transmittance electron microscopy (TEM) images show that regular SiO2-covered silver nanoparticles (br…
Superoleophobic surface prepared by using perfluorooctanoic acid modified titania (TiO2) nanoparticles is described. A variety of liquids, ranging from water to organic liquids, even the volatile liquids, such as toluene, chloroform and tetrachloromethane, exhibit typical spherical shapes on the fluorinated TiO2 surfa…

The excited-state behavior of a series of trans-2-(N-arylamino)stilbenes (aryl = phenyl (o1H), 4-methylphenyl (o1Me), 4-methoxyphenyl (o1OM), and 4-cyanophenyl (o1CN)) and trans-2-(N,N-diphenylamino)stilbene (o2) in both nonpolar and polar solvents is reported and compared to that of the parent trans-2-aminostilbene a…
INTRODUCTION: Safe and effective treatments are needed for ovarian cancer. While there are many drugs currently available, there has recently been a renewed novel interest in the use of anthracyclines. AREAS COVERED: This review summarizes the available evidence on pharmacokinetic (PK) and toxicology implications of a…
The local structures of transition-metal dopant atoms in semiconductor host lattices of dilute magnetic semiconductors are determined using resonant inelastic x-ray scattering. Ligand field multiplet calculations are employed to analyze experimental data and show when dopant atoms substitute into the lattice and when…
The focus of the present work is to study the effect of stress and temperature on the accumulated residual strain during the thermomechanical cycling of Shape Memory Alloys (SMAs). NiTi wires were pseudoelastically trained at different temperature above the austenitic finish temperature, up to different maximum applie…
The thermal conductivity of single-walled silicon carbide nanotubes (SW-SiCNTs) has been investigated by molecular dynamics (MD) simulation using the many-body Tersoff potential. To validate the reliability of the simulations code, the following measures have been taken: The calculated potential energies of SW-SiCNTs…
Protein crystallization has gained a new strategic and commercial relevance in the postgenomic era due to its pivotal role in structural genomics. Producing high quality crystals has always been a bottleneck to efficient structure determination, and this problem is becoming increasingly acute. This is especially true…
Drafting force is the direct and intuitive factor resulting in fiber motion in a drafting zone. Utilizing data collected from an ITT Draftometer, this paper discusses the effect of draft ratio and ratch in both the break and the main draft zones on drafting force and the coefficient of variation (CV) of drafting force…
Abstract Terbium alkoxides in homometallic ― [Tb 3 (μ 3 ‐O t Bu) 2 (μ 2 ‐O t Bu) 3 (O t Bu) 4 (HO t Bu) 2 ] ( 1 ), [Tb{OC( t Bu) 3 } 3 (THF)] ( 2 ) ― and heterometallic configurations ― [TbAl(μ 2 ‐O i Pr) 3 (O i Pr) 3 ( i PrOH)] 2 ( 3 ), [TbAl 3 (μ 2 ‐O i Pr) 6 (O i Pr) 6 ] ( 4 ) ― were synthesized and characterized b…
We report a theoretical study of the impact of finite size on the magnetocaloric effect (MCE) of thin Ho films. For strong external field strengths, the adiabatic temperature change ΔTad is comparable to the value found in bulk Ho, reaching about 12 K for an external field strength change ΔH = 50 kOe. For thicknesses…
To minimize radial compliance mismatch between native arteries and vascular prostheses over the entire blood pressure range, a biomimetic woven prosthesis sample with a bilayer wall has been developed. Poly(trimethylene terephthalate) (PTT) filaments were used as the circumferential yarns in the inner layer to increas…
In this research a novel method of coarse wool slandering with minimum tensile strength reduction was explored. To obtain the optimum condition, the response surface methodology through the central composite design in Design of Experiments (DOE) was applied and the optimum values for application conditions were obtain…
The aim of this study was to determine the metastable zone width of aqueous solutions of glycine for non-seeded batch crystallizations. The saturation curve was determined by studying the heating rate influence on the apparent saturation temperatures of several solutions. A linear regression was then applied to obtain…
