Using a rationally designed oxygen electrode based on a vertically aligned nitrogen-doped coral-like carbon nanofiber (VA-NCCF) array supported by stainless steel cloth, we have developed a nonaqueous Li–O2 battery with an energy efficiency as high as 90% and a narrow voltage gap of 0.3 V between discharge/charge plateaus. Excellent reversibility and cycleability were also demonstrated for the newly developed oxygen electrode. The observed outstanding performance can be attributed to its unique vertically aligned, coral-like N-doped carbon microstructure with a high catalytic activity and an optimized oxygen/electron transportation capability, coupled with the microporous stainless steel substrate.

These results demonstrate that highly efficient and reversible Li–O2 batteries are feasible by using a rationally designed carbon-based oxygen electrode.Keywords: carbon fibercatalystelectrochemistryLi−air batteryoxygen electrode Supporting InformationSketch of catalyst growth, extra SEM and TEM images of electrode and catalysts, and extra battery performances of current collectors. atmosphere air purifier 10-1076.View: ACS ActiveView PDF | honeywell pet cleanair air purifier for pet owners hht-013 reviews February 2014, Volume 91, Issue 2,honeywell 50250-s air purifier target pp 309–316CLA-Rich Soy Oil Margarine Production and CharacterizationOriginal PaperFirst Online: 13 October 2013Received: 14 July 2013Revised: 11 September 2013Accepted: 26 September 2013DOI:

AbstractA heterogeneous catalysis method to produce 20 % conjugated linoleic acid (CLA)-rich food-grade soy oil in 2 h without solvents or gases was recently developed. The objective of this study was to produce and characterize CLA-rich soy oil margarine relative to a soy oil control and commercial margarine. CLA-rich soy oil was used to prepare margarine. The samples were characterized for firmness, rheology, thermal behavior, solid fat content (SFC) and microstructure and compared with a soy oil control and commercial margarine. The CLA-rich oil margarine firmness and rheological properties were similar to commercial margarine and provided a better texture relative to the soy oil control margarine. However, SFC, droplet size distribution and melting behavior of CLA-rich oil margarine were similar to control soy oil margarine and dissimilar to the commercial product.

This suggests that hardness and rheological properties of margarine are not solely dependent on SFC and melting behavior. Lipid composition, polymorphism and microstructure differences in CLA-rich oil margarine may play an important role on the texture and rheological properties. A 7-g typical serving of the CLA-rich oil margarine will provide 0.6 g CLA. Thus five servings will provide 3.2 g/day of CLA and 185 calories/day, which is well within the maximum recommended 700–980 fat calories/day.KeywordsAbbreviationsCLAConjugated linoleic acidGCGas chromatographyFIDFlame ionization detectorTAGTriacylglyceridesFAMEFatty acid methyl esterst,ttrans,transt,ctrans,cisc,tcis,transLALinoleic acidSFCSolid fat contentDSCDifferential scanning calorimetryNMRNuclear magnetic resonanceSupplementary material11746_2013_2363_MOESM1_ESM.docxCopyright informationBelow are just a few of the manufacturers that TRICKL-EEZ IRRIGATION INC represents: Sprinklers, Dripperline, Filters, Regulators, etc.
