Observations of the dynamics and acoustics of travelling bubble cavitation
Individual travelling cavitation bubbles generated on two axisymmetric headforms were detected using a surface electrode probe. The growth and collapse of the bubbles were studied photographically, and these observations are related to the pressure fields and viscous flow patterns associated with each headform. Measur…
Scaling behavior in shaving cream
The coarsening of a three-dimensional foam is studied with multiple light-scattering techniques. Scaling behavior is observed with the average bubble diameter growing in time as ${\mathit{t}}^{\mathit{z}}$ where z=0.45\ifmmode\pm\else\textpm\fi{}0.05. Changes in the packing conditions during coarsening give rise to a…
A new lipophilic gadolinium chelate as a tissue‐specific contrast medium for MRI
Gd-Ethoxybenzyl-DTPA (Gd-EOB-DTPA) is a highly water-soluble paramagnetic contrast agent. Due to its protein binding of about 10% and its lipophilic residue, Gd-EOB-DTPA exhibits both renal (30% of the dose) and hepatobiliary (70%) excretion in rats. Despite its lipophilic character, the compound displays a low toxici…

Magnetocrystalline anisotropy and orbital moments in transition-metal compounds
The magnetocrystalline anisotropy energy and anisotropy of the orbital angular momentum have been calculated from first prinicples for Co and for a variety of intermetallic compounds including ${\mathrm{YCo}}_{5}$. For all compounds the predicted easy axes are in agreement with experiment. A strong correlation between…
Origin of superparamagnetism in nickel oxide
It has been known for some time that particles of nickel oxide of less than about 100 nm in size show superparamagnetism that increases as the particle size decreases. The origin of the particle magnetic moment responsible for this behavior has never been fully explained. This research indicated that the size of the p…
Electrical and optical properties of boron-doped ZnO thin films for solar cells grown by metalorganic chemical vapor deposition
The highly conductive and textured ZnO films have been grown by metalorganic chemical vapor deposition using diethylzinc and H2O as reactant gases. The B2H6 gas has also been successfully used as an n-type dopant gas to obtain highly conductive ZnO with a sheet resistivity for 2-μm-thick film as low as 10 Ω/⧠ at the v…
The Electrochemical Behavior of Calcium Electrodes in a Few Organic Electrolytes
The electrochemical behavior of calcium electrodes in a few important organic electrolyte has been investigated. The solvents used included acetonitrile, tetrahydrofuran, γ‐butyrolactone, and propylene carbonate, and the salts included , , , and tetrabutyl ammonium salts ( , ). Various techniques, including cyclic vol…
Quantum confinement effects in semiconductor clusters
The band gaps, band structure, and excited-state (exciton) energies of CdS, GaAs, and GaP semiconductor clusters are calculated using pseudopotentials. In addition, the sensitivity of the exciton energies to the size, shape, crystal structure, and lattice constant of the unit cell are investigated. The calculated exci…
Intrinsic dielectric loss in crystals
We review the current theory of intrinsic dielectric loss, that is the loss in a perfect crystal due to anharmonic interaction of a.c. electric field with the phonon system of the crystal. Both ordinary dielectrics and displacive ferroelectrics are considered. The theory predicts dependence of the loss on frequency ω…
