Unprecedented helix-based MMOFs with a cylindrical channel constructed from a single, newly designed Na(2)Pra(2)biim [Na(2)Pra(2)biim = 1,1'-di(propionic acid)-2,2'-biimidazole disodium salt], [M(Pra(2)biim)(H(2)O)](n) x xnH(2)O (M = Cd, Pb) have been presented, which are built from alternately arranged left- and righ…
Intravenous administration of 5-fluorouracil (5-FU) for colon cancer therapy produces severe systemic side-effects due to its cytotoxic effect on normal cells. The main objective of the present study was to develop novel oral site-specific delivery of 5-FU to the colon with less drug being released in the stomach or s…
The surface roughness evolutions of single crystal silicon, thermal silicon dioxide (SiO2), and low dielectric constant film coral in argon plasma have been measured by atomic force microscopy as a function of ion bombardment energy, ion impingement angle, and etching time in an inductively coupled plasma beam chamber…
Structural, Electrochemical, and Thermal Aspects of Li [ ( Ni0.5Mn0.5 ) 1 − x Co x ] O2 ( 0 ≤ x ≤ 0.2 ) for High-Voltage Application of Lithium-Ion Secondary Batteries, Myung, Seung-Taek, Ogata, Atsushi, Lee, Ki-Soo, Komaba, Shinichi, Sun, Yang-Kook, Yashiro, Hitoshi
The introduction of a urea-based anion binding site onto dibenzo-24-crown-8 can enhance the complexation between dibenzo-24-crown-8 derivatives and dibenzylammonium cation by ion-pair recognition.
Via hydrothermal synthesis, the self-assembly of Co(SCN)2 with the mixed rigid and flexible N,N′-bidentate donors, 4,4′-bpy and bimb (4,4′-bpy = 4,4′-bipyridine, bimb = 1,4-bis(imidazol-1-yl)-butane), generated a novel complex: [Co(bimb)(4,4′-bpy)(SCN)2] (1), which is the first example of an extended coordination poly…
Frequency response analysis (FRA) is a powerful and sensitive tool to assess the mechanical and geometrical integrity of core, windings and clamping structures within power transformers, by measuring their transfer functions over a wide frequency range. Despite a rapidly increasing number of users throughout the world…
Cobalt–iron–oxide (Co–Fe–O) nanoparticles have been prepared by the thermal decomposition in benzyl ether of Fe(acac)3 and Co(acac)2 in the presence of a mixture of oleic acid and oleylamine templating (surface capping) ligands, and 1,2-hexadecanediol (HDD) as an accelerating agent. The Co percentage may be tuned by a…
One of the major objectives of cluster science is to discover stable atomic clusters, which may be used as building blocks for cluster-assembled nanomaterials. The discovery and bulk synthesis of the fullerenes have sprouted new research disciplines in chemistry and nanoscience and precipitated intense interest to sea…
The microstructural mechanisms during dynamic globularization were investigated for ELI grade Ti-6Al-4V alloy with initial martensite microstructure. For this purpose, compression tests were carried out isothermally at 1073 K up to the strains of 1.0 and 1.4 with the strain rates ranging from 10−3 s−1 to 1 s−1. Fully…
The atomic layer deposition (ALD) process of hafnium–lanthanum oxide ( Hf La O x ) using La ( iPrCp ) 3 and Hf ( NEtMe ) 4 precursors is described. It has been found that when Hf precursor is introduced, the ALD process of La 2 O 3 is significantly improved in terms of its deposition rate and self-limiting property. A…
Abstract Eight kinds of density functionals named B3LYP, PBE1PBE, B1B95, BLYP, BP86, G96PW91, mPWPW91, and SVWN along with two different valence basis sets (LANL2DZ and CEP‐121g) are employed to study the transition‐metal dimers for the elements of group VIII. By comparing the equilibrium bond distances, vibrational f…
Cefpodoxime proxetil (CPDX-PR) is an oral cephalosporin antibiotic with poor aqueous solubility and bioavailability. Effect of beta-cyclodextrin on aqueous solubility and dissolution rate of cefpodoxime proxetil was evaluated by the formation of solid inclusion complexes in 1:2 molar ratio of drug: cyclodextrin. Phase…
Carbon nanofibers (CNFs) are treated with ammonia at elevated temperatures to generate pyridinic-type basic species on the CNFs surface. The basic species act as anchors for Pd nanoparticles, resulting in good dispersion and stability of the Pd nanoparticles. These ammonia-treated carbon nanofibers as Pd supports have…
A time dependent pulsed release system consisting of an effervescent core surrounded by consecutive layers of swelling and rupturable polymers was prepared and evaluated. The cores containing salbutamol sulphate as bioactive agent were prepared by direct compression method using different ratios of microcrystalline ce…
The reactivity towards H(2)O(2) of the complexes [Fe(pca)(2)(py)(2)].py (1) and Na(2){[Fe(pca(3))](2)O}.2H(2)O.CH(3)CN (2) (where pca(-) is pyrazine-2-carboxylate) and their catalytic activity in the oxidation of hydrocarbons is reported. Addition of H(2)O(2) to 1 results in the formation of a dinuclear Fe(III)-(mu-O)…
A novel combined technique of neutron diffraction and electron back scattering diffraction was applied to examine hierarchical deformation behavior of 18 mass% Ni martensitic steel. In-situ neutron diffraction experiment during tensile deformation demonstrated that intergranular stress was generated. EBSD analysis sug…
We have investigated the interactions of Cl and Cl2 with an anodized Al surface in an inductively coupled chlorine plasma. The cylindrical substrate is rapidly rotated within a differentially pumped wall and is exposed to the plasma 35% of the time through a conical skimmer. On the opposite side of the substrate, a se…
Because the inherent complexity of zeolites together with the use of high throughput technology make the performance of existing solutions for the automatic identification of mixture of crystallographic phases questionable, an adequate full profile search-match approach is presented, and its reliability is clearly dem…
The behavior of the positions and shapes of the fluorescence bands of di-, tetra-, and hexamethine merocyanine dyes with 3H-indolyliden (dyes 1–3) and benzoimidazolyliden (dyes 4–6) as electron-donating substituents and malononitrile as an electron-accepting substituent is studied by the method of moments in solvents…
