The relation between crystallographic texture and magnetic properties of GaP epilayers with embedded MnP nanoclusters grown by metal-organic vapor phase epitaxy is investigated with angle-dependent ferromagnetic resonance (FMR) measurements. A systematic methodology entirely based on magnetic characterization identifi…
Nanoparticles of strontium titanate (SrTiO${}_{3}$) have been synthesized in the 15 nm to 1 \ensuremath{\mu}m size range and studied using a combination of dielectric, Raman, x-ray, and neutron measurements. When diminishing the grain size, a strong reduction of dielectric permittivity, an enhancement of (normally for…
Pseudoternary xBaTiO3–yCaTiO3–(1−x−y)BaZrO3 (BT–CT–BZ) lead free piezoelectric ceramics were prepared by the conventional solid state reaction method sintered at 1450–1510°C for 2 h. Sintering conditions, composition and polarisation conditions exert great influences on structure and electrical properties of the sinte…
A new monomer, 2,6‐bis(4‐phenoxybenzoyl)naphthalene (BPOBON), was easily synthesized via simple synthetic procedures from readily available materials. A series of novel poly(aryl ether ketone)s containing both 2,6‐naphthylene moieties and amide linkages in the main chains were prepared by the Friedel‐Crafts acylation…
Scaling-down of phase change materials to a nanowire (NW) geometry is critical to a fast switching speed of nonvolatile memory devices. Herein, we report novel composition-phase-tuned GeSbTe NWs, synthesized by a chemical vapor transport method, which guarantees promising applications in the field of nanoscale electri…
SrRietveld is a highly automated software toolkit for Rietveld refinement. Compared to traditional refinement programs, it is more efficient to use and easier to learn. It is designed for modern high-throughput diffractometers and is capable of processing large numbers of data sets with minimal effort. The software cu…
The optimal contents of C, S, Cu and Sb in a new low alloy steel for the purpose of improving the sulphuric acid dewpoint corrosion resistance were investigated by weight loss and potentiodynamic polarisation in 50 wt-%H2SO4 at 70°C. The optimal elemental contents of C, S, Cu and Sb in the low carbon sulphuric acid de…
The concept of the directional pair distribution function is proposed to describe line broadening effects in powder patterns calculated from atomistic models of nano-polycrystalline microstructures. The approach provides at the same time a description of the size effect for domains of any shape and a detailed explanat…
Alumina‐chrome bodies were prepared by slip casting route. Slip casted bodies were sintered in the temperature range of 1550–1650 °C in reducing atmosphere with 2 h soaking time at peak temperature. Highly dense alumina‐chrome body with bulk density 4.24 g/cc and almost zero apparent porosity were obtained at 1650 °C.…
Abstract A ruthenium complex, KNa[Ru 2 (C 6 H 6 ) 2 (CH 3 COO) 6 ] (Ru‐KNa), and its polyoxotungstate derivative, Na 6 [{Ru(C 6 H 6 )} 2 W 8 O 28 (OH) 2 ] · 16H 2 O (Ru‐Na), have been successfully isolated from routine synthetic reactions and characterized by X‐ray single‐crystal structure analysis, IR spectroscopy an…
We report here single-layer ultracompact Fano-resonance photonic crystal membrane reflectors (MRs) at mid-infrared (IR) and far-IR (FIR) bands, based on single layer crystalline Si membranes. High-performance reflectors were designed for surface-normal incidence illumination with center operation wavelengths up to the…
Ba1−xSrxTiO3 (x = 0·3, 0·35) ceramics are fabricated by spark plasma sintering (SPS) technique and conventional sintering (CS) route. Their microstructures are determined together with the dielectric and ferroelectric properties. The grain sizes of SPS samples are smaller than those of CS. The differential scanning ca…
The objective of this work is to study the effect of sulphide ion on the corrosion behaviour of X52 steel in the simulated solution containing sulphate reducing bacteria metabolic products species. Linear polarisation resistance and electrochemical impedance spectroscopy results show that the addition of 50 ppm sulphi…
In the present study, ZnFe2O4 nanoparticles were synthesized by the chemical co-precipitation followed by calcinations at 473 and 673 K for 4 h. Particle sizes obtained were 4 and 6 nm for the calcination temperatures of 473 and 673 K, respectively. To study the origin of system’s low temperature spin dynamic behaviou…
Abstract Functionalized 1,2,4‐( R )‐triazole‐based Schiff base (R‐N=CH‐R′) ligands have been incorporated into spin crossover 1D materials of the general formula [Fe(Xtrz) 3 ](A) 2 · 2H 2 O (A = BF 4 , ClO 4 , Br, NO 3 ; Xtrz = triazole liands). The ligand N ‐salicylidene 4‐amino‐1,2,4‐triazole (Hsaltrz) and the novel…
All-trans retinoic acid (RA) has been proved to play important roles in regulating cell growth in various types of cells. Yet most experiments were performed by adding RA in solution previously. In this Article, we focus on the incorporation of RA, as a negatively charged moiety, into layered polyelectrolyte films on…
Na-vermiculite (Na-VMT) was exchanged with different contents of chlorhexidine acetate (CA) to prepare a CA intercalated Na-VMT (CA-VMT) hybrid, and then the morphology, interlayer arrangement, thermal stability, diffusion process and antibacterial property of the CA-VMT hybrid were evaluated. The results showed that…
Three new quinolone drug molecules modifying Keggin polyoxometalate compounds have been synthesized under hydrothermal conditions and structurally characterized. Single-crystal X-ray diffraction analysis shows that Keggin clusters modified by [Cu2(Enro)3H2O]4+ subunits result in formation of dimer {[Cu2(Enro)3H2O][SiW…
In this review, we will discuss the effects of itinerant hole and disorder produced by substitutions on the magnetic states of polycrystalline delafossite oxide CuCrO 2 having a spin-3/2 antiferromagnetic triangular sublattice. First, we will show the effects of hole-doping by the substitution of nonmagnetic Mg 2+ for…
Complex conductivity of FeSe 0.5 Te 0.5 superconducting films has been investigated using backward-wave-oscillator spectroscopy in the terahertz frequency range. The normal state conductivity corresponds well to the low-frequency limit of a Drude metal. In the superconducting state, the real part of the complex conduc…
