Two kinds of tris(beta-diketonato) metal(III) complexes denoted as [M(acac)2(LC12)] and [M(acac)2(Lazo)] (M=Ru(III) and Co(III); acac=acetylacetonato; LC12=1,3-didodecyloxyphenyl-1,3-propanedionato; Lazo=3-[4'-(4''-(butoxy)phenylazo)phenyl]-pentane-2,4-dionato) were synthesized and optically resolved into Delta, Lambd…
The crystal structures of diamagnetic dichloro(2-aza-2-methyl-5,10,15,20-tetraphenyl-21-carbaporphyrinato-N,N',N'')-tin(IV) methanol solvate [Sn(2-NCH 3NCTPP)Cl 2.2(0.2MeOH); 6.2(0.2MeOH)] and paramagnetic bromo(2-aza-2-methyl-5,10,15,20-tetraphenyl-21-carbaporphyrinato-N,N',N'')-manganese(III) [Mn(2-NCH 3NCTPP)Br; 5]…
Abstract Poly(ϵ‐caprolactone)diol (PCL) with five different molecular weights (e.g., 400, 2000, 3000, 4000, and 8000 g/mol) was grafted onto the surface of functionalized‐multiwalled carbon nanotubes (f‐MWNTs) by grafting to approach to form PCL‐ grafted ‐MWNTs (PCL‐ g ‐MWNTs). The grafting was confirmed by Fourier tr…
Conditions for electric discharge in a cavitation bubble, which experiences pulsations in a multibubble cavitation field, are considered. It is shown that, in the bubble, the development of an electron avalanche is most probable. Basic kinetic equations for diffusion, recombination, and other reactions of radicals wit…
The solubilities of clindamycin phosphate in different solvents (methanol, ethanol, and dimethyl sulfoxide) were measured at temperatures from (283.15 to 333.15) K by a synthetic method at atmospheric pressure. The experimental data were correlated with the modified Apelblat equation. The equation was found to provide…
Introduction : Metals have a wide range of applications in implant and prosthetic materials in dentistry. Corrosion resistance and biocompatibility of metals should be improved in order to utilize them as biomaterials. The aim of this work was to prepare metallic coatings on 316L stainless steel dental implants, to ev…
It can be expected that a chiral solvent possesses a certain potential to discriminate between two enantiomers by creating specific weak interactions and forming diastereomeric complexes which have different physical properties. Thus, for chiral solvents, there might be an asymmetry in the solubility phase diagrams th…
Molecular polarizabilities of photochromic diarylethenes bearing different chemical groups as substituents have been calculated by density functional theory (DFT) simulations with the aim to obtain an estimate of the refractive index of a glassy matrix containing diarylethenes as active species. Simple models have bee…
In this study, protein-conjugated Ag2S nanorods were prepared in aqueous solution, and high-resolution transmission electron microscopy (HRTEM) was used to track the whole process of the nanorod growth. Our results showed that the final products were formed via two-step oriented attachment, that is, particle-particle…
Abstract The mechanical properties of Ti6Al7Nb alloy deformed and heat treated at elevated temperatures were correlated with its microstructure and corrosion behaviour in Ringer (of different pH values: 2.49, 6.9 and 8.9) and Ringer–Brown solutions. Microstructural analysis revealed a Widmanstatten structure for the a…
It is shown that α-oxygen sites are generated by the decomposition of N 2 O in ion-exchanged Mn-ZSM-5 zeolites. The catalytic activity decreases to zero in 1 h, and the amount of α-oxygen that is formed is reduced from ∼30% α-oxygen sites per Mn atom in the initial N 2 O treatment to a value of ∼4% in the subsequent c…
We demonstrate the self-assembly through fluorophilic interactions of a blend of perfluorocarbon (RF) end-functionalized polystyrene and the corresponding RF-polybutylmethacrylate into optically transparent materials that retain domain characteristics typical of the component polymers but show well-defined lamellar na…
Structural and orientational order properties of 3Cy2CyBF2 and of 5CyCy2BF2 have been investigated by means of (13)C-NMR, optical, and dielectric spectroscopy methods. In the case of NMR, order parameters have been independently obtained from the analysis of either (13)C-(19)F dipolar couplings or (13)C chemical shift…
Oxygen exchange constants and oxygen diffusion coefficients were determined by relaxation (TGA-DSC and in situ XRD) and steady-state isotopic transient kinetic analysis (SSITKA) techniques as a function of oxygen partial pressure, temperature, and Co content for La 0.6 Sr 0.4 Co y Fe 1− y O 3−δ ( y = 0.1, 0.2, and 0.3…
Metallic nanoparticles synthesized by solution-phase chemistry usually exhibit various polygonal morphologies. The shape is known to have a great impact on a nanoparticle's optical properties, for instance, the surface plasmon resonance frequency. It remains unclear, however, whether the scattering spectrum of nanopar…
A method for noncovalent functionalization of DNA-wrapped single-walled carbon nanotubes (SWNTs) using platinum-based DNA cross-linkers is investigated. In particular, cisplatin and potassium tetrachloroplatinate are shown to bind to DNA that encapsulates SWNTs in aqueous solution. The bound platinum salt can then be…
The synthesis of ZnE (E = S, Se, Te) nanowires in solution via the solution−liquid−solid (SLS) mechanism is reported. Relatively low nanowire growth temperatures, between 340 and 350 °C, were made possible by using bismuth nanocrystals as seeds. Diethyl zinc and zinc(oleate) 2 were studied as Zn reactants, and TOP:E c…
A group of robust and easy-to-make photolabile protecting groups (PPGs) for carbonyl compounds has been developed. Sequential removal of different PPGs is achieved via control of irradiation wavelength.
Abstract We have developed a range of thin film coatings that are transparent in the visible, electrically conducting, adjustably birefringent and capable of aligning calamitic liquid crystals. The coatings were fabricated from indium tin oxide by oblique or glancing angle deposition, and a wide range of microstructur…
Catalytic properties of Pt nanoparticles can significantly depend on the crystallite shape, which renders shape control an important aim in the chemical synthesis. Starting from a colloidal synthesis of quasispherical Pt nanocrystals capped with dodecylamine ligands, systematic variations of different synthesis parame…
