Some organisms are capable of exerting exquisite control ower the crystals they form. Key components in this process are unusually acidic proteins (aspartic acid-rich). In this study we use a series of calciun dicarboxylic acid salts to investigate in vitro how these proeins are capable of interacting specifically wit…
The physical and electrochemical coloration characteristics of tungsten oxide films rf sputtered from a compressed powder WO3 target have been investigated. Oxide films with 3600–9800 Å thickness were deposited on substrates maintained at 200 °C at a total pressure of 0.5–8×10−2 Torr in Ar gas or an Ar-0.5-50% O2 gas…
Abstract Electro microscopy was used to study the phase separation kinetics of a polystyrene/polyvinylmethylether system subjected to a critical deep quench. The size of the phase‐separated domains was found to increase linearly with time, implying that hydrodynamic effects control the rate of growth of the domains in…
Abstract Introductory investigations performed in order to make quantitative electron‐probe microanalysis of very light elements such as boron, carbon, nitrogen or oxygen possible are described. The practical problems encountered in this kind of work are discussed in detail and, where possible, solutions are proposed.…
Abstract Junction probability diagrams show variation in both composition and layer arrangement in mixed-layer clay minerals. These diagrams can represent short-range and long-range ordered, random, and segregated interstratifications. Mineralogical analyses of illite/smectite from shale cuttings, bentonites, and hydr…
Abstract The reaction of smectite to illite in shale from the COST 1 well in the south Texas Gulf Coast and from altered ash-fall tuffs from the Morrison Formation in New Mexico was investigated using X-ray powder diffraction in conjunction with transmission electron microscopy. In the COST 1 well, the bulk of the det…

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…
