Polycrystalline tris-odium vanadium(III) nitridotriphosphate, Na3V(PO3)3N, was prepared by thermal nitridation of a mixture of NaPO3 and V2O5. The title compound is isotypic with Na3Al(PO3)3N. In the crystal, the P-atom and the three O-atom sites are on general positions, whereas the Na-, V- and N-atom sites are locat…
Bimetallic hollow PtAu sphere (H-PtAu) was prepared with TiO 2 (titanium glycolate spheres) as a template in the presence of citric acid, and the template was removed during the formation of H-PtAu. The morphology and surface structure of H-PtAu were characterized by transmission electron microscopy (TEM) and scanning…
Three highly aprotic bis(trifluoromethylsulfonyl)amide (NTf2(-)) based ionic liquids (ILs) containing the cations trihexyl(tetradecyl)phosphonium (P6,6,6,14(+)), N-butyl-N-methylpyrrolidinium (Pyrr4,1(+)), and (trimethylamine)(dimethylethylammine)dihydroborate ((N111)(N112)BH2(+)) have been examined as media for room…
1-Butene was isomerized to 2-butenes with a cis:trans ratio of ∼2:1 over Pd/TiO 2 under irradiation of UV light at room temperature, suggesting that a Pd/TiO 2 photocatalyst can function as an effective substitute for a Lewis acid catalyst and that the reaction rate can be controlled by photon flux as in the case of c…
The unique properties of ceramic foams enable their use in a variety of applications. This work investigated the effects of different parameters on the production of zirconia ceramic foam using the sol-gel process associated with liquid foam templates. Evaluation was made of the influence of the thermal treatment temp…
Thermal anneal is known to arrest the growth of laser-induced damage in optical materials. However, the response of the material which leads to this observed behavior is poorly understood. In this work, we investigate the effect of isothermal anneal at 1100°C for 12 hours on the growth rate of laser-induced damage sit…
This paper reports on changes in temperature and moisture content after plasticizing beech wood by microwave heating. There is currently no known use of microwave heating for plasticizing wood. Therefore, a proper procedure was developed to verify the use of microwave heating for the purpose of plasticizing. Moisture…
Hierarchical carbon‐encapsulated iron nanoparticles (Fe@Cs) with typical core/shell structure are successfully synthesized from starch and iron nitrate by an easy‐to‐handle process at different carbonization temperatures (600–1000 °C). The nanoparticles are characterized by transmission electron microscopy (TEM), X‐ra…
Cytotoxicity and subcutaneous tissue reaction of innovative blends composed by polyvinylidene fluoride and polyvinylidene fluoride-trifluoroethylene associated with natural polymers (natural rubber and native starch) forming membranes were evaluated, aiming its applications associated with bone regeneration. Cytotoxic…
Monodisperse magnetite nanospheres with hollow interior structure were synthesized through one‐pot solvothermal process, in an isothermal environment at 200°C for 12 h, using a sole iron precursor (FeCl3.6H2O) and without any template. We demonstrated the development of hollow structure of magnetite spheres by charact…
Five new flavonoid glycosides, namely nervilifordins F-J (1-5), were isolated from the 60% EtOH extract of the aerial parts of Nervilia fordii, along with three first isolated flavonoids (7, 8, and 13) and five known flavonoids (6, 9-12). The structures of new compounds were elucidated on the basis of 1D and 2D NMR an…
Cerium and nanocubes: CeO₂-supported Pd-Cu-alloy nanocubes (Pd-Cu NCs/CeO₂) with high content and good dispersion of the Pd-Cu NCs were prepared in high yields by heating a solution containing Pd, Cu, and Ce precursors. The prepared Pd-Cu NCs/CeO₂ have excellent catalytic activity and stability toward formic acid elec…
Abstract The reaction of the complex [{Ir(μ‐Cl)(ptpy)2}2] (1) with oxamide in methanol in the presence of sodium methylate as the base was investigated. During the reaction the new complex [Ir2(μ2‐oxamidato‐N,N′,O,O′)(ptpy)4] (2), ptpy = 2‐(p‐tolyl)pyridinato was obtained. The molecular structure of compound 2 was det…
The power conversion efficiency (PCE) of single-wall carbon nanotube (SCNT)/n-type crystalline silicon heterojunction photovoltaic devices is significantly improved by Au doping. It is found that the overall PCE was significantly increased to threefold. The efficiency enhancement of photovoltaic devices is mainly the…
In online transactions of textile products, fabric hand was thought to be inaccessible to consumers. Recently, much effort has been made to study the feasibility of providing consumers with a real sense of fabric through a virtual experience. The current paper proposes to extract fabric hand information from the persp…
The alkyl side chain length in poly(3-alkylthiophene) (P3AT) was found to affect the electrical properties and molecular electronic structures in thin films. The self-assembly and morphology of a P3AT film was easily controlled through the solvent vapor pressure (varied over the range 0–55 kPa) during solidification.…
Single-particle interactions hold the promise of nanometer-scale devices in areas such as data communications and storage, nanolithography, waveguides, renewable energy and therapeutics. We propose that the collective electronic properties possessed by noble metal nanoparticles may be exploited for device actuation vi…
Ag-Cu alloy catalysts for ethylene epoxidation have been shown to yield higher selectivity towards ethylene oxide compared to pure Ag, the unique catalyst employed in the industrial process. Previous studies showed that under oxidizing conditions Cu forms oxide layers on top of Ag. Using first-principles atomistic sim…
We present a one-to-one comparison of polymer segmental fluctuations as measured by small angle neutron scattering in a network under deformation with those obtained by neutron spin echo spectroscopy. This allows an independent proof of the strain dependence of the chain entanglement length. The experimentally observe…
We propose a general method that enables the acquisition of multiple 2D and 3D solid-state NMR spectra for U-(13)C, (15)N-labeled proteins. This method, called MEIOSIS (Multiple ExperIments via Orphan SpIn operatorS), makes it possible to detect four coherence transfer pathways simultaneously, utilizing orphan (i.e.,…
