Stoichiometric mullite powder (3Al 2 O 3 ·2SiO 2 ) prepared by spray pyrolysis and sintered at 1650°C attained 95% of theoretical density. The flexural strength was 360 MPa at room temperature and decreased slightly at 1400°C. A fairly high K Ic value (2.8 MN/m 3/2 ) was obtained. These mechanical properties can be at…
Following the discovery of a first-order phase transition in annealed KOH-doped ice at 72 K, which was identified as the order–disorder transition associated with the proton positions, a structural study has now been made. Powder neutron diffraction measurements on KOD-doped D2O above and below the phase transition, t…
A systematic study is presented of the effects of silicon dopant type, resistivity, current density, and hydrofluoric acid concentration on the formation and properties of porous silicon. Cross-section transmission electron microscopy revealed the presence of two distinct microstructures. The structure formed is deter…

This monograph presents a comprehensive and critical review of the 1074 published work on self-diffusion and chemical diffusion in oxide glasses. Where possible, the results on glasses are compared with those of the corresponding crystalline phases. Other ionic transport processes were also described, like electrical…
Abstract A new technique of decoration of the fold surface of polymer crystals is described. It is similar in methodology to gold decoration, but makes use of vapors of crystallizable polymers, principally polyethylene, as decorating material. Upon condensation and crystallization, the highly anisometric decorating mo…
This is the most comprehensive collection of data on the kinetics of crystallization from solution. This feature alone makes it a valuable addition to the literature on industrial crystallization. It provides a link between crystallization mechanisms and crystallization kinetics. The authors have put much effort into…
The transgranular stress-corrosion cracking of ductile alloys (and at least one pure metal) leads to a fracture appearance characteristic of cleavage. The experimental and theoretical background of this form of metal failure is reviewed. The discontinuous nature of crack growth in α-brass and copper is demonstrated us…
Failure of long-term synthetic arterial bypass grafts has been attributed in part to anastomotic stenosis, but the pathologic basis for this has not been determined. Which cells participate in the formation of the stenosis and the relationship between normal healing and the pathologic development of anastomotic narrow…
H+-translocating, Mg2+-ATPase was solubilized from vacuolar membranes of Saccharomyces cerevisiae with the zwitterionic detergent N-tetradecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate and purified by glycerol density gradient centrifugation. Partially purified vacuolar membrane H+-ATPase, which had a specific activit…
Use of precious metal catalyst is recommended in the tritium recovery system because it can oxidize tritium at ambient temperature. The ability to operate at the ambient temperature without preheating and past cooling is a large advantage in the ease of system operation. It is observed in this study, however, that the…

Water was irradiated with ultrasonic waves under an argon atmosphere which contained small amounts of carbon dioxide, nitrous oxide or methane. The yield of the products was measured as a function of the composition of the gas atmosphere. Maximum yields were observed at a few per cent of the added polyatomic gas. No c…
The electro-oxidation of pyrrole in the presence of anionic polyelectrolytes produces characteristic conductive black films of polymerically doped polypyrrole whose physical properties depend on those of the polyelectrolyte material.
The first graft copolymer of polypyrrole has been synthesized by electrochemically polymerizing pyrrole in the presence of pyrrole derivatized polystyrene; the copolymer produced exhibited an electrical conductivity comparable to that of polypyrrole.
Electrochemical polymerization of thiophene, 3-methylthiophene, and 3-ethylthiophene in propylene carbonate gave tough films, having conductivities of 190, 510, and 270 S cm–1, respectively.
Abstract
The field of fluid mechanics is rapidly advancing, driven by unprecedented volumes of data from experiments, field measurements, and large-scale simulations at multiple spatiotemporal scales. Machine learning (ML) offers a wealth of techniques to extract ...Read More

A critical assessment is given of the phase equilibria of the AI-Cu system. In the first section, the stable equilibrium diagram is constructed. In the second section, metastable and constrained equilibria are considered. These include metastable solvus curves of the AI-rich side of the diagram; on the Cu-rich side, t…
