Crossover from a displacive to an order-disorder transition in the nonlinear-polarizability model

M. G. Stachiotti、A. Dobry、R. Migoni 等 4 位作者1993-02-01Physical review. B, Condensed matter

The dynamics of a two-dimensional shell model with a double-well potential in the core-shell interaction is simulated by means of molecular-dynamics techniques. Snapshots of the lattice displacement pattern reveal the presence of precursor regions in the high-temperature phase, while in the low-temperature phase the d…

Perfluorooctylbromide as a contrast agent for CT and sonography: preliminary clinical results.

Michael Behan、D O’Connell、Robert F. Mattrey 等 4 位作者1993-02-01American Journal of Roentgenology

OBJECTIVE: Perflubron emulsion is a bromine-based particulate contrast agent that is taken up selectively by the liver and spleen after IV injection. It does not leave the vascular space and also persists in the blood for a longer period than iodinated contrast agents do. We performed a preliminary study to determine…

Improved TEM samples of semiconductors prepared by a small‐angle cleavage technique

J. P. McCaffrey1993-02-01Microscopy Research and Technique

A small-angle cleavage technique has been developed that produces superior transmission electron microscope (TEM) samples of semiconductors and related materials. The technique involves back-thinning the sample to approximately 100 microns, then scribing a groove on this back face at a specified small angle to a stand…

Excited-state absorption mechanisms in red-laser-pumped uv and blue upconversions inTm3+-doped fluoroaluminate glass

Setsuhisa Tanabe、Kazuki Tamai、Kimihiko Hirao 等 4 位作者1993-02-01Physical review. B, Condensed matter

The mechanism of red-pumped frequency-upconversion fluorescence observed in the uv and blue ranges of frequencies for a ${\mathrm{Tm}}^{3+}$-doped fluoroaluminate glass was investigated by single-wavelength pumping of a tunable 4-(dicyanomethylene)-2-methyl-6-(p-dimethyl-amino-styryl)-4H-pyran dye laser. It was found…

On the structure of irradiation-induced collision cascades in metals as a function of recoil energy and crystal structure

H.L. Heinisch、B.N. Singh1993-02-01Philosophical magazine. A/Philosophical magazine. A. Physics of condensed matter. Structure, defects and mechanical properties

The binary collision code MARLOWE is used to study cascade sizes, defect densities and subcascade configurations in f.c.c., b.c.c. and h.c.p. metals as a function of recoil energy up to 1 MeV. The threshold energies for the formation of subcascades are determined using a definition based on the defect configuration af…

Optical spectroscopy of the dimer system Cs3Yb2Br9

Markus P. Hehlen、Hans U. Güdel1993-02-01The Journal of Chemical Physics

Single crystals of Cs3Yb2Br9 were grown using the Bridgman technique. Well-resolved absorption, luminescence, excitation, and Raman measurements down to 5 K are reported and analyzed. The crystal-field splitting of Yb3+ in Cs3Yb2Br9 was determined and can be rationalized in terms of a trigonally distorted YbBr63− octa…

Coordination and organometallic chemistry of cyclophosphazenes and polyphosphazenes

Vadapalli Chandrasekhar、K. R. Justin Thomas1993-02-01Applied Organometallic Chemistry

Abstract This review describes the chemistry of cyclophosphazene and polyphosphazene ligand systems and their transition and organometallic complexes. The structures of the ligands and the complexes are discussed.

Three Zones for Illite Formation During Burial Diagenesis and Metamorphism

Dennis D. Eberl1993-02-01Clays and Clay Minerals

Abstract Reinterpretation of published data for shale cuttings from the Gulf of Mexico sedimentary basin identifies three reaction zones for illite formation with increasing depth for well CWRU6. In a shallow zone (1.85 to 3 km), non-expanding illite-like layers formed primarily by the coalescence of smectite 2:1 laye…

N-myristylation of the catalytic subunit of cAMP-dependent protein kinase conveys structural stability.

Wes Yonemoto、Maria L. McGlone、Susan S. Taylor1993-02-01Journal of Biological Chemistry

Coexpression of the yeast N-myristyltransferase with the murine catalytic subunit of cAMP-dependent protein kinase in prokaryotic cells results in the N-myristylation of the recombinant catalytic subunit. The acylated recombinant catalytic subunit was purified following in vitro holoenzyme formation with a mutant form…

Hydrodynamic instabilities in cylindrical thermocapillary liquid bridges

Hendrik C. Kuhlmann、H. J. Rath1993-02-01Journal of Fluid Mechanics

The hydrodynamic stability of steady axisymmetric thermocapillary flow in a cylindrical liquid bridge is investigated by linear stability theory. The basic state and the three-dimensional disturbance equations are solved by various spectral methods for aspect ratios close to unity. The critical modes have azimuthal wa…

Cong Wang、K. M. Ho、C. T. Chan1993-02-01Physical Review Letters

The structural and electronic properties of amorphous carbon are studied with tight-binding molecular-dynamics simulations. An amorphous carbon structure with 216 atoms obtained from our simulation gives a structure factor S(Q) in very good agreement with the results of neutron scattering from a sputtered a-C sample.…

Structure and electronic pseudogaps of stable quasicrystals

J. C. Phillips1993-02-01Physical review. B, Condensed matter

A variety of geometrical, crystal chemical, statistical, and quantum-mechanical theoretical constructs provide criteria for understanding trends in quasicrystalline relative stabilities. The quantum-mechanical constructs also explain trends in transport properties. These trends have predictive value.
