The authors report analytical studies of the adsorption-desorption transition of polymers grafted at a penetrable surface, in the 2D and 3D partially directed SAW models. The fraction of adsorbed monomers and the phase diagram of the transition are calculated by the transfer matrix method.
Transient phase response associated with a small angle relaxation from highly deformed nematic liquid crystal (LC) directors is analyzed experimentally and numerically. Qualitative agreement between computer simulations and experimental results is obtained. Based on these results, decay time of a fast LC modulator emp…
Article Crystal chemistry of iron in natural and in synthetic braunites Mn2 +(Mn3+,Fe3+ )6O8/SiO4 was published on November 1, 1988 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 184, issue 1-4).
Abstract Der Stahl W.Nr. 1.8907 wurde in flüssigem Ammoniak unter elektrochemisch kontrollierten Bedingungen bei etwa 20 °C in Zugversuchen mit konstanter Dehngeschwindigkeit an Rundproben auf Spannungsrißkorrosion geprüft. In reinem Ammoniak trat beim freien Korrosionspotential im Bereich der aktiven Korrosion keine…
FIM technique has been applied to investigation of structural state of an ordered alloy implanted by Ar+ and N+ ions. An ordering-disordering phase transition has been observed in the ordered solid solution Cu3Au after irradiation with ions' energies 15-20 keV and doses 1016-1018 cm-2. A near-surface region which has…
Abstract A quadricyclane derivative stable in water was first synthesized. Valence isomerization between the quadricyclane and the corresponding norbornadiene was very clean, to be promising for a solar energy storage system.
The structural phase transition in single crystals of KSCN which can be classified as improper ferroelastic, has been investigated by accurate birefringence measurements, Brillouin scattering and far infrared spectroscopy. The optical study showed the transition to be of first order. The temperature dependence of the…
Abstract Natural mound and intermound soil pedons were characterized to investigate native mound‐intermound formation and soil properties that may explain unfavorable plant growth that has been observed on sites of truncated mounds. Subrounded mounds average 26‐m apart, 15 m in diam., and 0.5 m in local relief. Mound…
The deterioration of Bronze Age objects from the archaeological site at Fort-Harrouard (France) has been studied, firstly, in relation to their external appearance and the elemental composition of the sound metal. A relationship between the composition of the corroded surface and the underlying sound metal was deduced…
The essential characteristics of NTC thermistor-type behaviour, besides the transition from a high resistance state to a permanent low resistance or memory state, have been analysed in the bulk modified glassy chalcogenide semiconductor Cu 0.05 As 0.50 Te 0.45 . Experimental results have shown a strong decrease in ele…

Article Indigo: Crystal structure refinement based on synchrotron data was published on November 1, 1988 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 184, issue 1-4).
Abstract Based upon the Doi-Edwards theory, a simple expression has been obtained for zero-shear viscosity in terms of the plateau modulus and the crossover frequency. There are no adjustable parameters in the expression. The model is in very good agreement with the zero-shear viscosity values for linear polybutadiene…
The eddy current loss under square-wave voltage excitation is theoretically and experimentally investigated. It is shown that the loss is smaller than under sinusoidal voltage excitation when the peak induction is the same. This decrease strongly depends on the behavior of domain structure.>

Low-energy electron-diffraction fine-structure data can often have relatively large inconsistencies associated with the electron-beam incidence conditions. This is in part due to the difficulties associated with working with electrons in the range 0--40 eV and in part due to the crystal being oriented azimuthally befo…
The ramie degumming efficiencies of three auxiliaries, sodium pyrophosphate, sodium metasilicate, and sodium sulfite, have been studied using a quadratic orthogonal rotation experimental design. Sodium pyrophosphate performs the function of a major auxiliary, but it can be replaced and replenished by sodium metasilica…
Coercivity Hc( f ) and initial permeability χi( f ) of two kinds of ferromagnetic glasses, 2605S2 and VAC6030, have been measured as a function of frequency from 4 Hz to 2 kHz. Field annealing and stretching of samples have been used to define an easy axis along the longitudinal direction. Some samples were thinned to…
A rigorous theory for chemical shifts in crystal is developed. In this formalism, it is clearly seen that the shielding tensor is divided into a demagnetizing term and a microscopic term. The former is caused by the demagnetizing field and is proportional to the bulk susceptibility. The latter is caused by a periodic…
