In article 2100068, S. T. Britt and P. C. Pistorius study liquid titanium-bearing iron (saturated with carbon) wets alumina crucibles. Wetting is caused by reaction between dissolved titanium alumina; it can be prevented pre-treating the crucible a flux containing calcium fluoride. By avoiding wetting, clear images of carbide formation on droplet obtained, during confocal scanning laser microsc...

This study was designed to develop an animal model of alcoholic pancreatitis and to test the hypothesis that the dose of ethanol and the type of dietary fat affect free radical formation and pancreatic pathology. Female Wistar rats were fed liquid diets rich in corn oil (unsaturated fat), with or without a standard or high dose of ethanol, and medium-chain triglycerides (saturated fat) with a h...

Phosphatidylethanolamine or phosphatidylcholine may be synthesized in mammalian tissues from diglycerides and cytidine diphosphate ethanolamine or cytidine diphosphate choline, respectively (1). Hydrolysis of the naturally occurring phosphatides has indicated that often the fatty acids at the @ position are unsaturated whereas those at (Y’ are more often saturated (2-4). Although it is possible...

In this study, the effect of limewater on strength assessments and percentage of water absorption of concrete incorporating ZnO 2 nanoparticles has been investigated. Portland cement was partially replaced by ZnO 2 nanoparticles with the average particle size of 15 nm and the specimens were cured in water and saturated limewater for specific ages. The results indicate that ZnO 2 nanoparticles u...

The electrochemical characteristics of an Au(111) electrode were investigated in 0.1 M KOH ethanol solutions containing various concentrations of decanethiol. Anodic and cathodic peaks corresponding to the oxidative adsorption and reductive desorption, respectively, of a self-assembled monolayer (SAM) of decanethiol were observed. Both peaks negatively shifted with the increase in the thiol con...

Acid and metalliferous drainage (AMD) is broadly accepted to be a major global environmental problem facing the mining industry, requiring expensive management and mitigation. A series of laboratory-scale kinetic leach column (KLC) experiments, using both synthetic and natural mine wastes, were carried out to test the efficacy of our pyrite passivation strategy (developed from previous research...

In a similar manner the non-existence of the compound LiNH, is established. In this case independent evidence is given which shows conclusively that in a system containing lithium and a small molecular per cent. of ammonia a saturated solution of the metal in ammonia is formed. This result is in agreement with the phase relationships existing in the system and demonstrates the inapplicability o...

Glycerolipid synthesis from [3H]glycerol and [l*C]dihydroxyacetone operated in enqmically isolated rat hepatocytes at a rate similar to that in the intact organ. Addition of albumin-bound fatty acids with more than 12 carbon atoms to the incubation medium markedly stimulated triacylglycerol synthesis from [3H]glycerol whereas the effects on phospholipid synthesis were smaller and more dependent...

Free fatty acids have been reported to induce cell death (lipotoxicity), but the effects depend on the carbon chain length and number of double bonds. Medium-chain saturated fatty acids (MC-SFAs), such as laurate, have less lipotoxicity than long-chain saturated fatty acids (LC-SFAs), such as palmitate. Monounsaturated fatty acids, such as oleate, have also been reported not only to exert cytot...
