A thermostable mutation, F51L, at the hydrophobic core of human alpha 1-antitrypsin (alpha 1AT) increased the conformational stability of the molecule by decreasing the unfolding rate significantly without altering the refolding rate. The mutation specifically influenced the transition between the native state and a c…
Characteristic 4f photoluminescence of Eu 3+ doped into ZnO was first observed on the red band luminescence. The intensity and fine structures of the Eu 3+ luminescence and their temperature dependence are strongly influenced by the doping conditions. In particular, for the increase of the Eu 3+ luminescence intensity…

Using neutron diffraction, x-ray scattering, and bulk-magnetization methods, we have characterized the magnetic structure for ${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$/NiO superlattices grown by molecular-beam epitaxy. The antiferromagnetic NiO order extends through several superlattice bilayers, even though the interveni…
Compositional changes which take place during sintering of Pb(Zr,Ti)O 3 (PZT) containing excess PbO were studied. The excess PbO forms a liquid phase during the sintering process. The solubility of the TiO 2 component of PZT in liquid PbO is higher than that of ZrO 2 component. Thus, if an excess PbO exists, the compo…

Recent advances in ferroelectric thin film technology have generated significant interest for use as capacitor dielectrics in semiconductor memories. Ferroelectric non-volatile memories (NVRAMS) have several unique features which set them apart from floating-gate non-volatile memories, including high-speed write opera…
Molecular dynamics computer simulations were employed to investigate defect production, atomic mixing and chemical disordering in β-NiA1 owing to 10keV cascades. The embedded atom potentials of Voter and Chen (1989) were employed. Point defect energies and threshold displacement energies were also obtained. The defect…

To what extent the host defense role of granule-associated antibacterial proteins and peptides of PMN includes extracellular action has not been established. To address this question, we have analyzed the antibacterial activity of cell-free (ascitic) fluid (AF) obtained from glycogen-induced sterile inflammatory rabbi…
Novel photo‐ and electroluminescent polymers based on poly( p ‐pyridyl vinylene), poly( p ‐pyridinium vinylene) and their butyl‐substituted derivatives are reported. The materials exhibit good fluorescence quantum yields and the butyl derivatives are soluble in conventional organic solvents. Highly luminescent thin fi…

Ab initio restricted Hartree–Fock 6-31G calculations are reported for the static longitudinal hyperpolarizability of the linear polyenes C4H6 through C44H46. Using a new extrapolation technique the infinite chain value in polyacetylene is determined with an accuracy similar to that achieved for small molecules. This i…
The paper describes how the classical formula of the Maxwell magnetic stress tensor may be extended to cover the magnetostriction phenomena. It is assumed that the ferromagnetic continuum is isotropic and conservative. The method takes into account the magnetic nonlinearity and it assumes that mechanical deflections a…
Abstract The influence of the spin reorientation phenomenon on the nucleation field of NdFeB magnets is analyzed based on the theory of micromagnetism. Results indicate that the temperature dependence of coercivity in the whole temperature range can be well described by the equation H c = (2 K 1 / M s ) × α K α ψ – N…

The SBAH was prepared by s…
The electronic defects in single crystals of yttria‐stabilized zirconia (YSZ) have been examined using electron paramagnetic resonance (EPR). The EPR spectra of hydrogen‐reduced YSZ single crystals are almost identical to those of polycrystalline yttria (12 mol%)‐stabilized zirconia‐titania, indicating that the Ti 3+…
