Single‐phase yttrium phosphate (YPO 4 ) and a YPO 4 /yttrium aluminate (Y 3 Al 5 O 12 ) laminate were studied. Young's modulus, Poisson's ratio, Vickers hardness, and coefficient of thermal expansion of YPO 4 sintered bodies were measured. YPO 4 and Y 3 Al 5 O 12 are chemically compatible and morphologically stable up…
The ground state of the neutral vacancy in diamond is diamagnetic and therefore has not been studied by electron paramagnetic resonance (EPR). We report the observation of EPR from the $^{5}$${\mathit{A}}_{2}$ excited state of the neutral vacancy by EPR when illuminating an electron-irradiated natural IaB diamond with…
Orientational dynamics in a simple model of infinitely thin hard needles, initially proposed by Rubinstein and Obukhov [1], are investigated by molecular dynamics simulations. The center-of-mass coordinates of the needles are fixed on a regular fcc lattice. The statics of the system is analytically known, yielding a g…
Abstract Two series of triblock copolymers of poly(ethylene glycol) (PEG, number‐average molecular weight M n = 6000) and poly( L ‐lactide) (PLLA) or poly( D ‐lactide) (PDLA) were prepared by ring‐opening polymerization of lactide initiated by PEG end groups using stannous octoate as a catalyst, either in refluxing to…
Abstract This study reports on the progression of processes occurring in polymer blends during mixing. For the polymer pellet blends studied, an abrupt phase inversion was observed simultaneous with attainment of maximum torque in the batch mixer. A four‐step phase inversion mechanism is described as predominant where…
Extended dendritic, ladder, and cross‐linked polyradical frameworks empolying π‐conjugated backbones (e.g. see Fig.) show promise in the development of ferromagnetic polymers. Recent progress in this field is reviewed and the various classes of materials, for example polyacetylene‐, or polyphenylenevinylene‐based radi…
Anisotropic charge transport, or polarized photo‐ and electroluminescence are possible applications for materials combining the optical properties of arylenevinylene polymers with the characteristic orientational order of the liquid‐crystalline state. Thermally stale, soluble materials with a broad mesophase, which ca…
We preesnt a theory for the effect of polymer nonideality on the phase behavior of a hard-sphere colloid plus nonadsorbing polymer mixture. Starting from the behavior at the \ensuremath{\theta} temperature, which has been treated previously within a mean-field framework [H. N. W. Lekkerkerker et al., Europhys. Lett. 2…
We present results for sonoluminescent (SL) radiation from a strongly modulated air bubble in water. The SL pulse is due to high temperatures in the bubble that are produced by the collapse of a shock wave. The dependence of SL radiation on acoustic pressure and initial bubble size is discussed, as well as the inclusi…
The properties of magnetic solids constructed from cyanometalate building blocks are reviewed. Most of these solids adopt face-centered cubic lattices in which adjacent metal centers are linked by CN bridges; they are analogues of the long-known inorganic coordination polymer Prussian blue. Ferromagnets, ferrimagnets,…
Dysprosium‐doped glasses were prepared in the system of gallium‐based sulfide, tellurite, zirconium‐baed and indium‐based fluorides and their optical properties were studied. From the absorption cross sections of five f‐f bands, three Judd‐Ofelt parameters, ω t ( t = 2, 4, 6), of Dy 3+ ion were determined. The composi…
Structure analysis and measurement of resistivity under both isostatic pressure smaller than 1.1 GPa and magnetic field of 1 T were carried out for rhombohedral ${\mathrm{La}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathit{A}}_{\mathit{x}}$${\mathrm{MnO}}_{3}$ (A=Na, K, Rb, and Sr). A close relationship was confirmed…

NIPP-1 was originally isolated as a potent and specific nuclear inhibitory polypeptide (16-18 kDa) of protein phosphatase-1. We report here the cDNA cloning of NIPP-1 from bovine thymus and show that the native polypeptide consists of 351 residues and has a calculated mass of 38.5 kDa. The bacterially expressed centra…
Abstract Ceramic-matrix composites (CMCs) are being developed for a number of high-temperature and high-performance applications in industrial, aerospace, and energy conservation sectors. This article focuses on processing, fabrication, testing, and characterization methods of CMCs, namely, discontinuously reinforced…
The effect of carbon black particle size and structure on the equilibrium volume swelling and elastic recovery of polychloroprene rubber immersed in hydraulic oil and subjected to uniaxial compression stress was investigated in this study.
