The theoretical Pourbaix diagram for the aluminum-water system does not take into account pitting corrosion, the usual form of corrosion for aluminum in chloride containing environments. To obtain a practical representation of aluminum corrosion usable in sea water, pitting potentials, protection potentials, and unifo…

Positive temperature coefficient (PTC) resistors for use as overcurrent protectors are now available with normal conduction mode resistances of about 0.04\Omega. This resistance is significantly lower than devices made from heretofore available barium titanate ceramics. PolySwitchTM overcurrent protectors are made fro…
The enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACPC deaminase) from a pseudomonad is a pyridoxal phosphate (PLP) linked catalyst which fragments the cyclopropane substrate to alpha-ketobutyrate and ammonia [Honma, M., & Shimomura, T. (1978) Agric. Biol. Chem. 42, 1825]. Enzymatic incubations in D2O yield alph…
The Fabry-Perot interferometer is being applied increasingly as a tunable filter. The theoretical limits to its performance are considered, including the effects of phase change at multilayer reflecting coatings. Various forms of construction are discussed as are several ways of tuning Fabry-Perot filters. The review…
Abstract Two types of oxygen desorption from La1−xSrxCoO3 were revealed by the appearance of a broad desorption peak(α) below ca. 800°C and a sharp one(β) around 820°C. The binding energy of O ls level for absorbed oxygen was clearly different from that for lattice oxygen. Close examination shows that α is ascribable…
Abstract Aniline Black coatings were obtained on Fe anodes by electrolyzing a basic solution of aniline in a water—methanol medium. Allylamine (an inhibitor of Fe corrosion), although not essential to the process, imparts better efficiency to it. The deposited polymers contain 15–20% azobenzene and exhibit semiconduct…

The preparation of fine-grained high-density compacts of heavily doped n-type Si63.5Ge36.5 alloy and the measurement of their thermal diffusivity over the temperature range 300 to 1150 K are reported. The compacts investigated possessed grain sizes (L) in the range 10<L<25 μm, 5<L<10 μm, an…
Dislocation structures of grain boundaries whose sliding behaviour had already been studied, have been observed by transmission electron microscopy of the slid grain boundaries. The ordered (coincidence) and random boundaries exhibited quite different sliding behaviour and dislocation structures. In the case of ordere…

The distribution of iodine in polyacetylene doped under conditons typical for most published work is investigated by energy dispersive X-ray analysis under an electron microscope. The 9.1 GHz dielectric constant of a series of iodine doped (CH)x is measured as a function of temperature. From the X-ray analysis we conc…
Recent experimental results on light scattering and absorption in polyacetylene are reviewed, and interpreted in terms of the soliton model. The data indicate that injection of an electron-electron (hole-hole) pair by chemical doping or photoinjection of an electron-hole pair invariably distort the lattice leading to…
