Abstract Synthesis, Crystal Structure and Spectroscopic Characterization of [Au 12 (PPh) 2 (P 2 Ph 2 ) 2 (dppm) 4 Cl 2 ]Cl 2 The reaction of [(AuCl) 2 dppm] (dppm = Ph 2 PCH 2 PPh 2 ) with P(Ph)(SiMe 3 ) 2 in CHCl 3 results in the formation of [Au 12 (PPh) 2 (P 2 Ph 2 ) 2 (dppm) 4 Cl 2 ]Cl 2 ( 1 ), the crystal structu…
We report a novel electric field effect on angular dependent magnetotransport in quasi-one-dimensional layered conductors with a pair of sheetlike Fermi surfaces. Under tilted magnetic fields and additional interlayer electric fields, semiclassical electron orbits on two Fermi sheets become periodic at different magne…
Although cells live in three-dimensional environments which consist of neighboring cells and cells’ own extra-cellular matrices (ECMs), so far Cell Biology restricted itself to only two dimensions of Petri dishes. However, micromechanical strains on cell surfaces significantly differ on Petri dishes from that in ECMs.…
Novel ruthenium(II) complexes, fac/mer-[Ru(MeCO-5Bpy-R)3]2+ (H-5Bpy-OH = 5'-amino-2,2'-bipyridine-5-carboxylic acid; R = -NHtBu, -NH(cHex), -N(cHex)2), have been synthesized. The fac and mer isomers have been successfully separated using HPLC techniques, and their photophysical/electrochemical properties have been inv…
Free radical polymerization of acrylamide (Aam) in the presence of aqueous solution of three commercial grades of polyvinyl alcohol (PVOH), namely, Vinarol FV (containing very few acetyl groups), Mowiol 4-80 (low viscosity-partially hydrolyzed), and Vinarol STH (medium viscosity-partially hydrolyzed), using ammonium p…

Atomic force microscopic (AFM) studies on the 50/50 blend of silicone rubber and fluororubber based on tetrafluoroethylene-propylene-vinylidene fluoride terpolymer reveal that the morphological features do not undergo appreciable change on 50% replacement of the fluororubber in the blend by its vulcanizate powder of f…
A procedure to produce stable hydroperoxy radicals (HO*2) in bulk amorphous SiO(2) (a-SiO(2)) has been developed. Oxygen molecules incorporated in the interstitial voids in a-SiO(2) react with mobile hydrogen atoms (H(0)) generated by the photolysis of silanol (SiOH) groups with F(2)-laser light (lambda = 157 nm, hnu…
We report the discovery of two-dimensional (2-D) nanotripods of ZnO, a new member of the ZnO nanostructure family. These planar nanotripods are synthesized via a novel approach known as catalyst-free combust-oxidized mesh (CFCOM) process that we developed using a ZnO factory furnace. At about 1200 °C, high velocity zi…
A polyester urethane was synthesized for use in a biodegradable scaffold. The polyurethane was synthesized in a two-step process: first, ester diol was synthesized from lactic acid and polyethylene glycol 400 (PEG 400), then it was polymerized with toluene diisocyanate using dibutyl tin dilaurate (DBTDL) as a catalyst…
The mechanical properties of Nylon 6,6 blended with recycled scrap material, polyvinyl butyral (PVB), using maleated styrene-ethylene-butylene-styrene block copolymer (SEBS-g-MA) as a compatibilizer are discussed. Control samples of Nylon 6,6/PVB blends and Nylon 6,6/SEBS-g-MA blends were also compared. The results sh…
Epitaxial La0.8Ag0.1MnO3+δ films of different thicknesses (500–1000 nm) were grown on ZrO2(Y2O3) substrates. Their optical, magneto-optical and transport properties were studied in order to clarify the effect of the epitaxial variant structure and Ag ion distribution on the conductivity, magnetoresistance and infrared…
The negatively charged oxygen donates an electron pair to the hydrogen, and the hydrogen attached to the nitrogen accordingly weakly bonds with oxygen. The nitrogen in the polyaniline backbone finally possesses extra negative charge due to the donation of electron density by the oxygen.
High impact polystyrene (HIPS) series was synthesized by the mass-suspension process using polybutadiene (PB) rubbers with different cis-1,4, trans-1,4, and vinyl-1,2 isomers content. The HIPS were characterized by TEM, GPC, DMA, and DSC analyses. It was found that the dynamic mechanical properties of HIPS strongly de…
Abstract Pale yellow, needle‐shaped single crystals of Sm 2 [SeO 3 ] 3 were obtained by heating stoichiometric mixtures of Sm 2 O 3 and SeO 2 (molar ratio: 1:3) along with substantial amounts of CsCl as fluxing agent in evacuated sealed silica tubes at 830 °C for one week. According to X‐ray single‐crystal diffraction…
In a study of the TDDB performance of an ultra-low-k (ULK) dielectric (JSR 5537 k = 2.3) it was found that the presence of moisture significantly reduced the TDDB lifetime as well as increased leakage and capacitance. It was also observed that the field coefficient (/spl gamma/) in an "E" TDDB lifetime model was signi…
Some mechanisms of the reduction reaction of NO by CO on rhodium are analyzed and discussed, solving the kinetics equations and using Monte Carlo simulations, in terms of its ability to interpret the recent experiments of Zaera et al., who used a molecular beam method to study experimentally the kinetics of the reacti…
Abstract Alcoholysis of [Fe 2 (O t Bu) 6 ] as a Simple Route to New Iron(III)‐Alkoxo Compounds: Synthesis and Crystal Structures of [Fe 2 (O t Amyl) 6 ], [Fe 5 OCl(O i Pr) 12 ], [Fe 5 O(O i Pr) 13 ], [Fe 5 O(O i Bu) 13 ], [Fe 5 O(OCH 2 CF 3 ) 13 ], [Fe 5 O(O n Pr) 13 ], and [Fe 9 O 3 (O n Pr) 21 ] · n PrOH New alkoxo‐…
We study the propagation of electromagnetic waves in infinite lines with grafted finite lines in a frequency regime, where the grafted lines have negative phase velocity. The physical properties of such a structure with negative phase velocity materials have not been investigated before, to the best of our knowledge.…
To cap it all…︁ The pyrolysis of a [CpFe(arene)]PF6 complex yielded new carbon nanocapsules in near-quantitative yield (see TEM image); the capsules contain an Fe–P composite material. The results show that the structure of the obtained material is highly dependent on the complex used in the pyrolysis experiments, and…
