Abstract A new conceptual model for interstratified clays is proposed, based on complementary use of the transmission electron microscope (TEM) and X-ray diffraction (XRD). Clays yielding interstratified XRD patterns are shown to be composed of aggregates of fundamental particles (here defined as an individual or free…

The Landau theory of blue phases (BP) in cholesteric liquid systems is further developed by systematically including the effect of higher harmonics in the structure factor on the free energy. The inclusion of a third harmonic results in two new body-centered-cubic (bcc) structures, ${O}_{b}^{8}$ and ${O}_{c}^{8}$, in…

Structures corresponding to various potential energy minima have been examined for a classical model whose pair interactions produce a body-centered-cubic crystalline ground state. The method used is molecular dynamics computer simulation for 128 particles with frequent steepest-descent mapping onto nearby minima. The…

A new photosensitive high temperature polymer stable up to 500%deg;C with high photosensitivity and high resolution has been developed. The trend toward a high degree of integration in solid-state technology requires the use of new high temperature photosensitive insulating materials. Toray's Photoneece system provide…

Sulfolobus solfataricus is a thermophilic archaebacterium able to grow at 87 degrees C and pH 3.5 on glucose as sole carbon source. The organism metabolizes glucose by two main routes. The first route involves an ATP-dependent phosphorylation to give glucose 6-phosphate, which readily isomerizes to fructose 6-phosphat…

The consequences of differences in the intramolecular force constants and the ionic entropies between the oxidized and reduced states of aquo redox couples upon their electrochemical kinetics are examined as a function of the driving force. A generalized harmonic oscillator model is utilized that involves estimating t…

The rates of reaction of 3CaO. Al 2 O 3 , in sulfate‐containing solutions of three compositions were investigated. It was observed that the rates of calcium and sulfate uptake decreased with increasing calcium hydroxide concentration. In a further experiment using a calcium sulfate solution, which also contained NaOH,…
