Conventional methods that are used to overcome multidrug resistance (MDR) often involve the coadministration of chemosensitizers and anticancer drugs. However, coadministration of many chemosensitizers with anticancer drugs, such as doxorubicin (Dox) has resulted in the exacerbation of anticancer drug toxicity. Here,…
Solid solutions of Sr 9+ x Ni 1.5 - x (PO 4 ) 7 that are structurally related to β-Ca 3 (PO 4 ) 2 are formed in the compositional range of 0.14 ≤ x ≤ 0.39. We investigated static disorder in Sr 9.3 Ni 1.2 (PO 4 ) 7 ( x = 0.3, space group: R 3̄ m ) by X-ray and neutron powder diffraction. The electron-density distribut…
Abstract A novel cage complex [Cu6Cl(MeO)2(pz)9] (1) was synthesized via a chloride ion template reaction and structurally characterized. In 1, two trinuclear units, {Cu3(MeO)(pz)3}2+, are linked by three pyrazolate ligands, six copper(II) ions form a trigonal prism, and a chloride ion is located at the center of the…
In order to study the wearing comfort of pressure for tight‐fit clothing, the sensation of wearing pressure and the other related sensations have been assessed for knit garments, which have different sizes and fabrics which have different extensibilities, by developing a wearing experimental procedure. Using factor an…
Abstract Poly(ethylene‐ co ‐vinyl acetate) (EVA) powders containing 10 and 20 wt % of vinyl acetate (VAc) units was saponified in ethanol/KOH solution in a heterogeneous manner. Intermolecular interaction between vinyl alcohol(VOH) units in the produced poly(ethylene‐ co ‐vinyl alcohol) (EVOH) promoted the crystalliza…
Abstract A flexible computational model for the initiation of crevice corrosion has been developed. Based upon a mechanistic theory, empiricisms do not limit the scope of this work. The model is formulated in a previous paper and this sequel publication showcases the performance of the algorithm. Designed for widespre…
Abstract CsOH is investigated, as an alternative to the traditionally used KOH, for the preparation of glycerine initiated polyols. CsOH allows polyether–polyols with higher molecular weights and lower unsaturation contents, ie of better quality, to be obtained. CsOH also increases the reaction rate and permits reduct…
The chemical stability of an amorphous silicon carbonitride ceramic, having the composition 0.57SiC·0.43Si 3 N 4 ·0.49C is studied as a function of nitrogen overpressure at 1873 K. The ceramic suffers a weight loss at p N2 < 3.5 bar (1 bar = 100 kPa), does not show a weight change from 3.5 to 11 bar, and gains weig…
Abstract The service reliability of stainless steels and alloys is predominantly determined by the chemical stability of an ultrathin passive film on their surfaces. The thickness, composition and structure of such an ultrathin oxide film are all influenced by the alloy composition and the nature of the environments t…
The materials used for the pressure-retaining parts of reactor coolant system components in light water reactor nuclear power plants have to meet special requirements in terms of their mechanical properties, workability and in-service performance. Corrosion issues play an important role in connection with plant operat…
Abstract A series a coil coating primers, based on high‐molecular‐weight epoxy resins and a urea formaldehyde crosslinking agent, have been investigated by angle‐resolved XPS (ARXPS) analysis. The addition of a low amount of flow agent additive (<0.2 wt.%) in the formulations induced significant changes in the surf…
The [Cu(cyclam)] 2+ (copper-1,4,8,11-tetraazacyclotetradecane)−saponite complex has been obtained by an ion exchange reaction, and a thin film for the [Cu(cyclam)] 2+ −saponite complex has been prepared by spin-coating onto glass slides. The orientation and the structural change of the guest complex ion in the interla…
Photoinduced electronic energy transfer (EET) and electron transfer (PET) have been investigated in a multichromophoric system 2, that comprises zinc porphyrin (ZnP), dimethoxynaphthalene, and [60]fullerene (C 60 ) chromophores separated by norbornylogous bridge sections of six and five bond lengths, respectively. In…
[formula: see text] [1.1](3,3')-Azobenzenophane, in which two azobenzenes are cyclically connected by -CH2- chains at the meta positions, has been synthesized. The crystal structures of all isomers have been revealed. This is the first report on the crystal structure of the cis isomer of macrocyclic azobenzenes. The t…
The adoption of a field-theoretical approach to problems arising in the framework of electrical insulation is discussed with reference to six main topics, which have been addressed over the last 30 years. These include uniform field electrodes, Green's differential equation, electrode surface roughness, induced charge…
Cyclic deformation has been performed at ambient temperature on ultrafine-grained copper processed by equal channel angular pressing. Observations by electron channelling contrast in a scanning electron microscope revealed that pronounced recrystallization occurred and several distinct dislocation configurations such…
Redox disproportionation of benzyl alcohol to benzaldehyde and toluene catalysed by the Pd561phen60(OAc)180 (phen=1,10-phenanthroline) giant cluster 1 under anaerobic conditions was found, whereas in an O2 atmosphere cluster 1 catalyses the oxidation of benzyl alcohol to benzaldehyde and inhibits further oxidation of…
In the present study, we proposed a simple method to locate defect sites in individual SWNTs with an AFM technique by using a thermal oxidation strategy. After thermal oxidation of well-dispersed SWNTs on a silicon surface in air at 500 °C, almost all of the original SWNTs were fractured into short fragments. The rang…
In this work, primary, secondary and tertiary bis(amide) derivatives of DTPA have been synthesized and the residence time of the water molecule coordinated to their gadolinium complexes has been measured by variable temperature 17O NMR spectroscopy. The influence of substituent characteristics (molecular mass, hydroph…
The thermal behavior of 4 coal samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) methods. Upon heating the coals in an inert atmosphere up to 800 ° C, 31.44-43.82% weight loss occurs. The 2 temperature regions of increased chemical reactivity are evident in t…
