The structural and magnetic properties of Tm2Fe17−xCrx (x=0, 0.5, 1.0, 1.5, and 2.0) compounds are investigated by means of x-ray diffraction and magnetization measurements. The Tm2Fe17−xCrx compounds have a hexagonal Th2Zi17-type structure. There exist a negative thermal expansion coefficient for Tm2Fe17−xCrx compoun…
The effect of stress on void nucleation during solid–solid reaction of ZnO/Al2O3 core–shell nanowires and multilayer structures through the nanoscale Kirkendall effect is investigated. A flexible stress-mediated approach is suggested to spatially define the localization of large Kirkendall voids in these systems. New…
We explored how to increase liquid crystal sensitivity to external magnetic fields. Suspensions consisting of a mixture of liquid crystal and spindle type mono-dispersed hematite nano-particles at concentrations lower than 1 wt% were prepared. The Fréedericksz transition threshold for the suspensions appeared to be lo…
Abstract The effect of organo‐modified clay (Cloisite 93A) on the crystal structure and isothermal crystallization behavior of isotactic polypropylene (iPP) in iPP/clay nanocomposites prepared by latex technology was investigated by wide angle X‐ray diffraction, differential scanning calorimetry and polarized optical…
The effect of the beeswax, Span 20, and glycerol content on qualities of soybean-protein-isolate edible films was evaluated. Beeswax and Span 20 were selected to improve qualities of soybean-protein-isolate films from 11 emulsifiers. The content of beeswax, Span 20, and glycerol was further optimized by response surfa…
A phase diagram for morphotropic (Pb0.985La0.01)(Zr1−xTix)O3 is proposed based on a combination of X-ray and neutron powder diffraction experiments and complemented by transmission electron microscopy. Dependent on composition three regions are characterized. The stability range of tetragonal microdomains for high Ti…
By using high resolution x-ray photoelectron spectroscopy, we show that inelastic scattering of photoelectron at low temperature (30-50 K) generates two kinds of oxygen species on Pt (111) surface. Intense synchrotron radiation source dissociates oxygen molecules into chemisorbed atomic oxygen and induces the formatio…
Surface modification of lanthanide-doped upconversion nanocrystals is crucial to make them useful for various biological applications. Unfortunately, the current methods available to achieve a desirable surface exhibiting both high luminescence and good biocompatibility are limited. In this work, we present a facile m…
Real-time deformation of individual multiwalled boron nitride nanotubes (BNNTs) was investigated using an atomic force microscopy (AFM) stage installed inside the chamber of a transmission electron microscopy (TEM) system. These in situ AFM-TEM experiments were conducted in following two deformation regimes: a small-a…
Decamethylchromocene, Cr(II)(eta(5)-C(5)(CH(3))(5))(2) (2), readily reduced [1,2,5]thiadiazolo[3,4-c][1,2,5]thiadiazole (1) in a tetrahydrofuran solvent at ambient temperature with the formation of radical-anion salt [2](+)[1](-) (3) isolated in 97% yield. The heterospin salt 3 ([2](+), S = 3/2; [1](-), S = 1/2) was c…
Synchrotron X-ray microdiffraction was used to characterize the deformation structure of single crystalline Cu micro-tensile specimens which were oriented for single slip. The 3-µm thick samples were strained in situ in a scanning electron microscope (SEM). Electron microscopy observations revealed glide steps at the…
Orthoconic Antiferroelectric Liq. Cryst. (OAFLC) have been extensively studied due to their unique electrooptical properties [1 D'have , K. , Dahlgren , A. , Rudquist , P. , Lagerwall , J. P. F. , Anderson , G. , Matuszczyk , M. , Lagerwall , S. T. , Dąbrowski , R. , & Drzewiński , W. ( 2000 ). Ferroelectrics , 244 ,…
The study of 27 new meso-substituted free-base and metal complexes of tetraphenylporphyrins with substitution by alkoxygroups (from -OC4H9 to -OC16H33) in para-, meta-, or ortho-position has been carried out. Out of 11 synthesized free-base alkoxysubstituted tetraphenylporphyrins – 4 possess mesomorphic state of colum…
Zink macht den Unterschied: Das Polyoxometallat 1 reagiert mit Zn2+-Ionen in Aceton nahezu quantitativ zum neuartigen Sandwich-artigen POM 2. Die Oxidation sekundärer Alkohole mit H2O2 verläuft mit 2 effizient, und zwar mit Aktivitäten und Chemoselektivitäten, die sich von denen wolframhaltiger Katalysatoren einschlie…
High cesium (Cs)‐bearing sodium borosilicate glasses incorporated with varying concentrations of TiO 2 up to 10 mol% at the expense of B 2 O 3 were prepared by the conventional melt quenching method. Physicochemical properties of the glasses studied include Cs volatilization losses, leaching, and glass transition temp…
Gold nanorods can be used as extremely bright labels for differential light scattering measurements using two closely spaced wavelengths, thereby detecting human disease through several centimeters of tissue in vivo. They have excellent biocompatibility, are non-toxic, and are not susceptible to photobleaching. They h…
Bi 0.90 La 0.10 Fe 0.95 Zn 0.05 O 3 (BLFZO) thin films were grown directly on Pt/TiO2/SiO2/Si(100) substrates without any buffer layer by off-axis radio frequency sputtering. The BLFZO thin film deposited at 580 °C possesses a single-phase purity, while those deposited at other temperatures exhibit a varying amount of…
A laboratory incubation experiment using soil columns was conducted to study the effects of monocalcium phosphate (MCP) and potassium chloride (KCl) on soil pH changes in fertilizer microsites with two Chinese soils. Mixtures of two fertilizers at two rates (0 and 0.26 g per column) were added to the surface of soil c…
The spectra of far-infrared transmission in ${\text{Tb}}_{3}{\text{Fe}}_{5}{\text{O}}_{12}$ magnetoelectric single crystals have been studied in the range between 15 and $100\text{ }{\text{cm}}^{\ensuremath{-}1}$, in magnetic fields up to 10 T, and for temperatures between 5 and 150 K. We attribute some of the observe…
