The requirements of brake materials were outlined and a survey made to select materials to meet the needs of high temperature brakes. A number of metals and ceramic materials were selected and evaluated in sliding tests which simulated aircraft braking. Nickel, molybdenum tungsten, Zr02, high temperature cements and carbons were tested. Additives were then incorporated into these materials to optimize their wear or strength behavior with particular emphasis on nickel and molybdenum base...

Process studies for converting cubane-1,4-dicarboxylic acid to cubane-1,2,4,7-tetracarboxylic acid were carried out. The diacid was converted to the diacid chloride which was reacted with t-butylethylamine to give cubane- lithium 2,2,6,6-tetramethylpiperidide and magnesium bromide etherate to give dimetallated intermediate which was carbonated with carbon dioxide. The resulting diacid bisamide was the hydrolyzed with 70% nitric acid to give the tetraacid in 60% yield based on the diacid. The...

By a test involving a combination of static and dynamic loading, the carboxylic acids are shown to be embrittling to high-strength steel to a degree proportionate to the carbon chain length. It is shown that nonpolar liquids are in general not embrittling but that the magnitude of the dipole moment is not a measure of embrittling propensity. Evidence indicates that under appropriate conditions, a -Cl group is potentially as embrittling as an -OH or a -O- group. (See also AD-427 068).

This the final report for ARO W911NF-09-1-0290. Prior reports on this project give further detailed information. Of greatest importance in this work has been our novel discovery of heterogeneous deprotection of sulfonic acid esters. The consequence will be that we can form precision placed sulfonic acid groups along a polymer chain. This has never been done before. If the morphology arranges as we expect it to (based on what we observed in the case of carboxylic acid precision placement) then...

A series of 4,4,8,8-tetrahalopyrazaboles of the type X2B(mu-pz*)2BX2 (Hpz*= C-substituted pyrazole, X = Cl,Br) has been prepared by reaction of the corresponding B-tetrahydro derivatives with elemental halogen. The reaction of (C2H5)2O.BF3 with pyrazabole, H2B(mu-pz)2BH2, has been used for the preparation of both F2B(mu-pz)2BF2 and F2B(mu-pz)2BF2 and F2B(mu-pz)2BH2 (Hpz = pyrazole). The later was chlorinated to yield the unsymmetrical B-tetrahalopyrazabole Cl2B(mu-pz)2BF2. 4,8-Dihalopyraboles,...

The authors describe the synthesis of 5-ethyl picolinic acid 5-ethyl- 2-methyl pyridine. As methods of oxidation, they chose the reaction of Vilgerodt, the conversion of 2-methyl-5-ethylpyridine by way of N-oxide into 2- oxymethyl-5-ethylpyridine with a subsequent gentle oxidation, a condensation of the a-methyl group with benzaldehyde and oxidation of the stilbazole, and direct oxidation of the methyl group by selenium dioxide.

Hexamethylbenzene (HMB) was difficult to be oxidized with an alkaline potassium permanganate solution, since HMB was insoluble in an aqueous alkaline solution. But, when HMB was warmed with 50% nitric acid for a short time, and then treated with aqueous potassium permanganate, the reaction occurred readily and dimethylpyromellitic acid was obtained. When HMB was warmed with 50% nitric acid for 1 to 2 minutes, a yellow material was produced, which was soluble in hot aqueous potassium hydroxide,...

The major objective of this study was to evaluate light-regulated ethylene production during gravitropic bending in etiolated pea stems. Previous investigations indicated that ethylene production increases after gravistimulation and is associated with the later (counter-reactive) phase of bending. Additionally, changes in the counter-reaction and locus of curvature during gravitropism are greatly influenced by red light and ethylene production. Ethylene production may be regulated by the levels...

The polymerization of 2,4'-methylene-dianiline with benzophenone tetracarboxylic acid dianhydride yields high molecular weight polyamic acid. Polyimide is formed when films of the polyamic acid are cured between 200 - 300 C. A lower molecular weight polyamic acid is obtained from 2,2'-MDA with BTDA, but it appears that a lowering of the reaction temperature will yield high molecular weight polymer. Evaluation of these polymers is underway. Continued efforts to synthesize 2,3'- MDA and...

A kinetic study of the polymerisation of acrylamide initiated by the thermal catalyst 4-4'-azo-bis-4-cyanopentanoic acid showed that up to 10% conversions the rate of polymerisation is directly proportional to the concentration of monomer and to the square root of the concentration of catalyst. In the presence of ferric perchlorate and decimolar perchloric acid, however, the overall rate of polymerisation is reduced and the rate now becomes directly proportional to the first power of the...

For the embryolethality tests, semicarbazide and isoniazid showed a slightly less-than-additive embryolethal response. Potentially different lethal modes of action may be observed for compounds that are thought to be teratogenic by the same mode of action. For the embryolethal binary mixture test of hydroxyurea and isoniazid the 3:1 mixture showed an antagonistic response, while the 1:1 and 1:3 mixtures were response additive, as expected. The antagonistic response may have been the result of...

Poisoning by cyanide can be verified by analysis of the cyanide detoxification product, alpha-ketoglutarate cyanohydrin (alpha-KgCN), which is produced from the reaction of cyanide and endogenous alpha-ketoglutarate. Although alpha-KgCN can potentially be used to verify cyanide exposure, limited toxicokinetic data in cyanide-poisoned animals are available. We, therefore, studied the toxicokinetics of alpha-KgCN and compared its behavior to other cyanide metabolites, thiocyanate and...

Irradiation of aqueous solutions of oxalic acid, (COOH)2, with 2.5 Mev x rays for exposure of ^10(exp 6) roentgens causes a decrease in the number of both reducing and acid equivalents. Solutions of formic acid, HCOOH, show similar decreases under deuteron and electron irradiation. Approximate values of G (molecules converted per 100 ev) for oxalic range from 4 to 6; for formic acid the values are 2.5 for electrons and 1.7 for deuterons.
