Two copper(II) coordination polymers formulated {[Cu3(HL)2(MeOH)2(H2O)2]·2H2O}n (1) and {[Cu4(L)2(H2O)8]·5H2O}n (2) were obtained utilizing the polycarboxylate ligand 2-(bis(carboxymethyl)amino)terephthalic acid (H4L) and characterized by X-ray diffraction, FT-IR spectra, elemental analysis and EPR spectra. 1 crystall…
Mesoporous aluminosilicate catalysts having different Al/Si ratios were synthesized following a hydrothermal synthesis route and using different aluminum sources, such as aluminum nitrate and aluminum isopropoxide. These mesoporous materials have high surface areas, in the range of 520–1001 m2/g, and exhibit Type IV n…
An amphiphilic polystyrene-C 60 -poly( N -isopropylacrylamide) (PS-C 60 -PNIPAAm) block copolymer was successfully prepared through atom transfer radical polymerization, demonstrating the facile approach to obtain two-armed polymer-C 60 nanohybrids, in which the C 60 molecules bond to two different polymeric arms. The…
Expression of vimentin in gastric cancer was immunohistologically examined in 85 surgically resected specimens and evaluated in terms of various clinicopathological features. Vimentin expression was more pronounced in gastric cancers of more advanced type and in those exhibiting a higher degree of infiltrative growth,…
Poly(acrylic acid- ran -styrene) (P(AA- r- S)) and poly( tert -butyl acrylate- ran -styrene) (P( t BuA- r -S)) random copolymers previously made with different molar ratios (0, 4.5, and 9 mol %) of additional free nitroxide mediator, N - tert -butyl- N -[1-(diethylphosphono)-2,2-dimethylpropyl]nitroxide (SG1), relativ…
Biofouling of all structures immersed in seawater constitutes an important problem, and many strategies are currently being developed to tackle it. In this context, our previous work shows that poly(ethylene glycol) monoacrylate (PEGA) macromonomer grafted on preoxidized poly(methyl methacrylate) (PMMAox) films exhibi…
Pd37(CO)28{P(p-Tolyl)3}12 (1) was obtained in approximately 50% yield by the short-time thermolysis of Pd10(CO)12{P(p-Tolyl)3}6 in THF solution followed by crystallization via layering with hexane under N2. The low-temperature (100 K) CCD X-ray diffraction study of 1 revealed an unusual non-spheroidal Pd37-atom polyhe…
We derive a continuum theory for the phase transition in a classical dimer model on the cubic lattice, observed in recent Monte Carlo simulations. Our derivation relies on the mapping from a three-dimensional classical problem to a two-dimensional quantum problem, by which the dimer model is related to a model of hard…
An oligothiophene tweezer molecule, which has two quaterthiophene moieties connected to create an electrochemically activated hinge, has been synthesized. Two-electron oxidation of the tweezer molecule produces an intramolecular pi-dimer between the two oligothiophene moieties at room temperature as confirmed by UV-vi…
The effect of a magnetic field on the photocurrent generated by a bulk heterojunction solar cell made from poly-3-hexylthiophene (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) is investigated. At the operating voltage, increases in photocurrent of ∼9% can be obtained at magnetic fields of less than 100 m…
PURPOSE: To prospectively test the hypothesis that iron labeling of radioembolization microspheres permits their visualization by using magnetic resonance (MR) imaging for in vivo tracking during transcatheter delivery to liver tumors. MATERIALS AND METHODS: All experiments were approved by the Institutional Animal Ca…
Four fanlike organic compounds, 1-ethoxybenzene (EOB), 1-butoxybenzene (BOB), 1-dodecyloxybenzene (DOB), and 1-(dodecyloxy)-2-methoxybenzene (DOMB), were chosen as guests, and beta-cyclodextrin (beta-CD) and its two derivatives, mono(2-O-2-methyl)-beta-CD and mono(2-O-2-hydroxy-propyl)-beta-CD, were chosen as hosts. E…
The adsorption of a metallo-supramolecular coordination polymer (Fe-MEPE) in the cylindrical pores of SBA-15 silica with pure and carboxylic acid (CA) carrying pore walls has been studied. Fe-MEPE is an intrinsically stiff polycation formed by complexation of Fe(II)-acetate with an uncharged ditopic bis-terpyridine li…
We report a microwave-assisted solvothermal method for the preparation of AlOOH hierarchically nanostructured microspheres constructed by nanosheets. The formation mechanism of AlOOH hierarchically nanostructured microspheres is discussed. γ-Al 2 O 3 hierarchically nanostructured microspheres are obtained by heating A…
A reversible, critical phase separation induced by UV light at 350 nm has been achieved by doping a small amount of photosensitive surfactant into an AOT-stabilised water-in-decane microemulsion. The initial and separated phases were analysed by small-angle neutron scattering (SANS), which suggests irradiation produce…
In the present study, the kinetics of esterification of acetic acid with isobutanol was studied by using Amberlite IR-122 as an acid catalyst. Experiments were carried out in a stirred batch reactor in dioxane at different temperatures (323 to 348 K) under atmospheric pressure. The equilibrium constant was found to be…
We identify an optimized three-dimensional metallic photonic-band-gap filament architecture for electrically pumped, quasithermal, visible light emission. This identification is based on extensive band structure and finite-difference time-domain calculations of metallic photonic crystals. The optimum structure consist…
Sub-micrometer and nano-size catalytic particles are significantly more reactive than their bulk counterparts and can be used to enhance the performance of catalytic combustors. Their high specific surface areas (typically 1−200 m 2 /g) and unique morphologies contribute to their enhanced reactivity. Differences in ad…
In this paper, we relate experimental electron beam induced etching profiles to various electron limited and mass transport limited regimes via a continuum model. In particular, we develop a series of models with increasing complexity and demonstrate the effects and interactions that the precursor gas adsorption kinet…
In this study, the efficiency of boron removal from Balçova geothermal water provided by the Izmir Geothermal Energy Company, Turkey, has been investigated using boron selective ion exchange resins Diaion CRB 02 and Dowex (XUS 43594.00) by batch and column methods. The results of the column studies have been evaluated…
