Abstract The formation of volatile aromatic pyrolyzates in poly(vinyl chloride) has been studied by pyrolysis–gas chromatography–mass spectroscopy. Results from isotopic labeling experiments with perdeutero‐PVC suggest that the aromatic pyrolyzates can be divided into three general classes with respect to their format…

The strength improvement of an injection‐molded and sintered silicon nitride ceramic (15.5 wt% Y 2 O 3 +10.1 wt% SiO 2 ) produced by an oxidation heat treatment at 1500°C is reported. The ceramic retains its strength after prolonged intermediate temperature exposure in air, whereas the untreated material suffers vario…

Heat-stable L-lactate dehydrogenase [EC 1.1.1.27] was purified from an extremely thermophilic bacterium belonging to the genus Thermus, and it showed an allosteric nature dependent on fructose 1,6-bisphosphate as an effector. The enzyme had a molecular weight of approximately 120,000 with a subunit molecular weight of…

Abstract Pyrrole reacted with potassium persulfate in aqueous media to form polymers or “pyrrole blacks.” The structure and molecular weight depend on the initial pyrrole/K 2 S 2 O 8 ratio. An ESR line due to trapped electrons or free radical ions appeared at g = 2.0036 (width 3.6 G) in all products and its intensity…

The dependence of the hard magnetic properties of melt-spun Nd1−xFex (0.5⩽x⩽0.7) and Pr1−xFex (0.4⩽x⩽0.7) alloys on quench rate is reported; the latter was controlled by varying the substrate surface velocity (vs ) of the melt-spinner. All of the alloys show an appreciable maximum in coercivity (Hci ) as a function of…

Abstract The glass and melting transitions of poly(ethylene terephthalate‐co‐ p ‐oxybenzoate)s have been studied by differential scanning calorimetry. Despite the higher glass transition expected for polyoxybenzoate, there is almost no change in the glass transition temperature up to 63 mol % oxybenzoate (353 ± 4 K).…

In clean SF6 gas-insulated power transmission systems significant pre-breakdown discharges are rarely observed. This is so because the prevailing electric field is only moderately non-uniform. In practical systems, however, conducting particle contamination creates regions of highly non-uniform fields. Initial ionizat…

An important characteristic of a grain boundary is the depth to which its displacement field penetrates into the neighbouring single crystals. This boundary thickness, which is called the ‘structural width’ in this paper, may be studied by the use of an electron diffraction technique which is sensitive to the width of…
