The excess thermodynamic quantities of lanthanides and actinides in molten salts and liquid metals were studied for reductive extraction of minor actinides. The excess enthalpies and entropies of those elements in the molten chloride phase were found to be correlated with the ionic radii of metal ions possibly due to…
Six heterometal-organic frameworks, {[LnCu1.5(BPDC)3(H2O)2].mH2O}n (Ln = Gd (1, m = 4.75), Tb (2, m = 3.75), Eu (3, m = 5), Ho (4, m = 2), Yb (5, m = 2.25), BPDC = 4,4-dicarboxylate-2,2-dipyridine anion), and {[LuCu1.5(BPDC)3(H2O)1.5].2.5H2O}n (6), have been synthesized under hydrothermal conditions. The structure ana…
The magnetic anisotropies and easy axes of magnetization at room temperature were determined, and the effects of rare-earth (RE) ions were clarified for RE-based cuprates, RE-doped bismuth-based cuprates and RE-doped Bi-based cobaltite regarding the grain orientation by magnetic field. The easy axis, determined from t…
A facile route to biocompatible poly(lactic acid-co-glycolic acid)-co-poly(ethyleneglycolmethacrylate) (PLGA–PEGMA) block co-polymers is described utilising a combination of ring-opening polymerisation (ROP) and reversible addition fragmentation transfer (RAFT) methods. A series of PLGA–PEGMA polymers varying in co-mo…
Electron transfer and delocalization of the pi systems were investigated in mono- and dinuclear Ru complexes with the zwitterionic ligand L = N,N'-diisopropyl-2-amino-5-alcoholate-1,4-benzoquinonemonoiminium.
Planar anisotropies of r-values are calculated from crystallite orientation distribution functions (ODFs) by using the Taylor theory. These values are compared with experimentally obtained values for two kinds of ferritic stainless steel sheets with different planar anisotropies of the r-values and different texture g…
Magnetic pulse welding was applied to the lap joining of crystalline pure aluminum and metallic glass (Zr48Cu36Al8Ag8 and Cu50Zr42.5Al7.5) and interfacial microstructure was examined. The metallic glass fractured in brittle manner in conventional plate layout. However, Al/metallic glass joints were successfully obtain…
Sacrificial layer electrophoretic deposition (SLED) is a technique to assemble nanoparticles that yields free-standing, multilayered nanoparticle films with macroscopic lateral dimensions after the sacrificial layer is dissolved.
Two-dimensional dispersions of colloidal particles with a range of surface chemistries and electrostatic potentials are characterized under a series of solution ionic strengths. A combination of optical imaging techniques are employed to monitor both the colloid structure and the electrostatic surface potential of ind…
The determination of a single test temperature for asphalt mixtures to simulate major distresses on flexible pavement is quite significant in characterizing asphalt mixtures. It is apparent that the practical use of a single temperature would reduce testing needs as well as relevant analysis efforts. Effective tempera…
Nonstoichiometry is reported in the system. As lithium is removed from crystalline by chemical or electrochemical methods, the resulting two-phase mixture consists of stoichiometric and a delithiated phase, , whose lattice parameters depend on the global extent of delithiation and on the crystalline domain size of the…
This research investigated the vitrified bond CBN wheel for MQL grinding of cast iron. Grinding under the dry, MQL, and flood cooling conditions were evaluated and compared in terms of forces, surface roughness, workpiece temperature and energy partition. Compared to flood cooling, CBN MQL grinding can achieve the sam…
Nanocrystals of four transition metal oxides (TMOs) were prepared by a novel quick precipitation method and characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). From the XRD patterns, average particle sizes for CuO, NiO, Co 2 O 3 , MnO 2 are calculated to be 15 nm, 4 nm, 13 nm, 40 nm, r…
The sugar sensitive microcapsules were prepared by a layer-by-layer deposition of concanavalin A (Con A) and glycogen on a calcium carbonate particle containing fluorescein-labeled insulin (F-insulin). The Con A/glycogen multilayer capsules were formed through sugar-lectin interactions by using inner and outer poly(et…

The anionic fluorescent dye, aminopyrene trisulfonic acid (APTS), was synthesized and used in a solution-based two-component glucose-sensing system comprising the dye and a boronic acid-appended viologen. The fluorescence of the dye was quenched in the presence of the viologen and the fluorescence restored upon glucos…
Abstract: There are various methods to evaluating phosphate rock for direct application. The first approach is solubility test of Phosphate Rocks (PR) using chemical extractant. In this study to compare the effectiveness of direct application of PRs, two samples of a sedimentary unbeneficiated PR from Lar mine of Yaso…
ABSTRACT In this research, mechanical characteristics of double submerged arc‐welded line pipe steel of grade API X70 (70 ksi yield strength) were investigated. Different experimental examinations including chemical analysis, microstructural investigation, microhardness, tensile and Charpy tests and standard fractogra…
Among the functional nucleic acids studied, adenine-rich nucleic acids have attracted attention due to their critical roles in many biological processes and self-assembly-based nanomaterials, especially deoxyribonucleic acids (abbreviated as poly(dA)). Therefore the ligands binding to poly(dA) might serve as potential…
In this paper, we report the successful synthesis of cobalt phosphide (Co2P) nanostructures built up of nanorodsvia a simple hydrothermal route using white phosphorus (WP), sodium hypophosphite and cobalt dichloride as starting reactants in the presence of polyvinylpyrrolidone (PVP, 30 K). The as-obtained product was…
