Thallium(III) oxide is a degenerate n‐type semiconductor which can be electrochemically or photoelectrochemically deposited on conducting or semiconducting substrates. The material is highly conductive, transparent, and electrocatalytic. A photoelectrochemical cell consisting of the n‐silicon/thallium(III) oxide photo…
Abstract The demixing behavior on cooling of ternary systems of cellulose acetate/solvent/water has been examined for CA concentrations up to 40 wt% CA in several solvents. Cloud points have been measured as a function of cooling rate. The rapid process of liquid—liquid demixing can be discriminated from the slow proc…
A “16-structure" was found from careful surface cleaning manners and RHEED observations to be only a superstructure appearing on a clean Si(110) surface. The present work also confirmed clearly that almost all surface structures reported previously were superstructures characteristic of Ni-contaminated Si(110) surface…

This work was undertaken to study the effects of various doses of locally applied epidermal growth factor (EGF) on developing granulation tissue in rats. Cylindrical hollow sponge implants were used as an inductive matrix for the growth of granulation tissue. In the test groups, the implants were injected daily with a…
The magnetic field dependence of the solvent water proton longitudinal relaxation rate 1/T1 (the NMRD profile) has been measured for solutions of chelates of Gd3+ and Mn2+ ions with two different polyaza macrocyclic ligands: 1,4,7-triazacyclononane-N,N',N",-triacetic acid (NOTA) and 1,4,7,10-tetraazacyclododecane-N,N'…
The system was investigated by the ac‐impedance method, covering both the semi‐infinite and the finite (very low frequency) diffusion regimes. Upon decreasing the modulation frequency, a transition from semi‐infinite diffusion to finite diffusion is observed, with different apparent diffusion coefficients calculated f…
It is observed that the linewidth and line shape of the Zeeman resonance associated with dangling bonds at the (111)Si-${\mathrm{SiO}}_{2}$ interface (${P}_{b}$ centers) vary with the direction of the applied magnetic field. An analysis of the line shape of this resonance indicates that it can be represented analytica…
The title macrotetrolide contains two maleic diester units that add hydrophilic sulfur nucleophiles, e.g., bisulfite, thioacetic acid, and various thioglycosides, in high yield. Two-headed amphiphiles (“bolaamphiphiles” or “bolytes”) are thus formed. They produce extremely thin (hydrophobic part ~20 Å) monolayer lipid…

We recently reported the partial characterization of a new human collagen termed Type VII. This molecule is distinctive among the collagen family in that it contains three identical subunit alpha chains within a triple helical domain 424 nm in length. The molecule contains three identical alpha chains which are geneti…

We study the properties of one-dimensional quasilattices numerically and analytically. The geometrical properties of general one-dimensional quasilattices are discussed. The Ising model on these lattices is studied by a decimation transformation: The critical temperature and critical exponents do not differ from those…
Abstract As investigated by optical and electron microscopy, the observed morphology of the meltblended polyethylene/polystyrene pair unambiguously supports the interfacial activity of poly(hydrogenated butadiene‐ b ‐styrene) copolymers. The phase size is significantly reduced, the interfacial adhesion is dramatically…
A first step in the quantification of receptor density in the living human brain is the measurement of the binding of a labeled ligand to the receptor in question. In the present study, we determined the rate of binding of 11C-labeled N-methylspiperone (NMSP) to the D2 dopamine receptor in 11 normal volunteers, using…

Abstract Actual procedures for the preparation of black phosphorus single crystals by a bismuth flux method have been explored and the details are described. The anisotropy and the temperature dependence of the electrical conductivity and the Raman scattering spectra of the crystals obtained by the above-method have b…
BO-PP films have fairly different morphologies to those of non-oriented PP films. These morphological differences were found to originate from the orientation of the crystalline and amorphous phases. The orientation of the amorphous phase causes a pronounced decrease observed both in ionic conduction and in dielectric…
A model has been developed for the prediction of NOx emissions from combustion turbines. Thermal, prompt, and fuel NO are all treated and are all assumed to be formed at a stoichiometric equivalence ratio. Prompt and fuel NO are assumed to be fast with respect to thermal NO and establish a finite concentration of NO a…
