Abstract The study reported herein focused on the electronic structure of the {Ru(NO)} 6 fragment and characterization of the oxidation state of ruthenium in mer , trans ‐[RuCl 3 (Hind) 2 (NO)] ( 1 ; Hind = 1 H ‐indazole) resulting from the reaction of mer , trans ‐[RuCl 3 (H 2 O)(Hind) 2 ] ( 2 ) with NO in acetone or…
Trifluoroacetate metal-organic deposition (TFA-MOD) is a promising technique to fabricate YBa2Cu3O7-δ (YBCO) superconducting films. However, its slow pyrolysis process, which usually takes more than 10 h, constitutes a barrier for industrial production. In this study, polyethylene glycol (PEG) was utilized to reduce t…
Abstract Three new oligomers bearing furan, thiophene, or bithiophene units end‐capped by benzofuran moieties were synthesized and studied with respect to their structural, optical, electrochemical, and electrical properties. A comparison of the electronic properties performed by theoretical calculation, absorption an…
A straightforward approach was proposed to decorate gold nanoparticles onto recyclable supports based on magnetite/polymer composite materials for highly efficient catalysis. Cross-linked particles bearing a controllable content of catechol active residues were synthesized by precipitation polymerization of mussel-ins…
We report a detailed characterization of the noncentrosymmetric superconductor Re24Ti5 using powder x-ray diffraction (XRD), magnetic susceptibility, electrical resistivity, thermal conductivity, Seebeck coefficient, and specific heat measurements. Rietveld refinement of powder XRD data confirms that Re24Ti5 crystalli…
We have investigated nano-scale magnetic structures to learn how magnetic behaviors differ from what is observed in bulk materials. In this study, we have measured the magnetic hysteresis of individual multilayered nanowire using a magnetic force microscopy (MFM). The nanowires were composed of low-aspect ratio segmen…
Three-dimensional interconnected porous poly(ε-caprolactone) scaffolds have been prepared by a novel solventless scaffold fabrication approach combining cryomilling and compression molding/porogen leaching techniques. This study investigated the effects of processing parameters on scaffold morphology and properties fo…
The pathogenesis of L-cystine kidney stones involves four critical steps: nucleation, crystal growth, crystal aggregation, and crystal adhesion to cells. Although inhibition of crystal growth by L-cystine "imposters" at L-cystine crystal surfaces has been suggested as a plausible route for the suppression of stones, u…
We examine the suitability of cluster expansion methods for the description of inhomogeneous fluids. In particular, we apply these methods to characterize the density profile, surface tension, and excess adsorption for a hard-sphere fluid near a hard wall. Coefficients for these series up to seventh order are evaluate…
In this research, effects of screw diameter, screw type, panel type, and end distance on lateral resistance of the joints made with drywall and sheet metal screws were studied in bagasse particleboard and the results were compared to those obtained from commercial medium density fiberboard (MDF). The accuracy of EYM i…
The aim of this research was developing alginate nanoparticles as a carrier for food enrichment. In this research, Fe/Zn-loaded alginate nanoparticles were prepared and characterized as point size, morphology, FTIR, loading efficacy (LE), and release properties and used in ice cream structure. After this stage, absorp…
Dehydrated hydroxyapatite (HAp), OH− ion-defect induced hydroxyapatite, was prepared for dielectric measurements. We evaluated the dielectric properties of HAp in 100–500 °C, and found dielectric relaxations of two kinds. At lower temperature, relaxation that was attributed to the reorientations of OH− ions was observ…
The wide scatter in experimental results has not allowed drawing solid conclusions on self-diffusion in the chalcopyrite CuInSe2 (CIS). In this work, the defect-assisted mass transport mechanisms operating in CIS are clarified using first-principles calculations. We present how the stoichiometry of the material and te…
We developed a novel mixed binder of MgO (magnesia) and supplementary cementitious materials that can solidify sediments contaminated with heavy metals as well as store CO2 through mineral carbonation reactions. The optimal MgO‐based binder consisted of MgO, lime (L), fly ash (FA), and blast furnace slag (BFS) with a…
Seeking to understand why the cubic centre in MgO:Cr(3+) has the same 10Dq value as emerald, ab initio cluster and periodic supercell calculations have been performed. It is found that the equilibrium Cr(3+)-O(2-) distance, R, in MgO:Cr(3+) is equal to 2.03 Å and thus 0.06 Å higher than that measured for the emerald.…
The traditional multiconfiguration Hartree–Fock (MCHF) and configuration interaction (CI) methods are based on a single orthonormal orbital basis. For atoms with many closed core shells, or complicated shell structures, a large orbital basis is needed to saturate the different electron correlation effects such as vale…
A new ruthenium sensitizer Ru-acac ( cis -bis(thiocyanato)(2,2′-bipyridyl-4,4′-di(3-pentane-2,4-dione)(4,4′-dinonyl-2′-bipyridyl)ruthenium(II)) functionalized by acetylacetone (acac) anchoring groups was synthesized and studied in ZnO-based dye-sensitized solar cells (DSCs). In comparison with the parent ruthenium com…
Results of an experimental study are presented in which the impact of a low power laser beam on the stability behaviour of plasma arcs was investigated. Both heat sources were arranged in a recently developed coaxial set-up. Bead on plate welding trials on AISI 304 stainless steel sheets demonstrated that the addition…
Knowledge of the martensite start temperature in low and medium alloy steels is of critical importance for steel makers, or any industry involved in the transformation of hardenable steels. Its determination is often carried out by length change measurements in quenching dilatometers. The present paper focuses on the…
Abstract Carbon supports with a low ratio of micropore volume to total pore volume can be prepared by KOH activation of thermally modified carbon. KOH treatment of carbons in nitrogen led to the creation of basic sites as well as acidic surface groups, whereas KOH treatment in air resulted in more acidic groups. Steam…
