  • Aliphatic
  • The effects of barium, calcium and zinc salts of the aliphatic dicarboxylic acids on the nucleation ability and formation of β-crystalline form in isotactic polypropylene (iPP) were investigated. (springer.com)
  • The results showed that barium, calcium and zinc salts of aliphatic dicarboxylic acid were related to the number of carbon atoms in the acids, and carbon atomic numbers of 5-8 had good nucleation ability for iPP except calcium adipate and zinc pimelate, in which barium glutarate, calcium suberate and zinc suberate were highly efficient β-nucleating agents for iPP.

  • aqueous
  • Observed changes in the isotopic composition of dicarboxylic acids in all phases as fog forms, matures, and evaporates will aid in determining how these acids are processed in both gas-phase and aqueous-phase photochemical aging. (epa.gov)
  • Due to the nature and behavior of small dicarboxylic acids that are common constituents of atmospheric samples, it is expected that reactions forming secondary organic aerosols in the aqueous phase will result in an increase in aerosol particulate matter, since it is likely that their precursors originate in the gas phase.

  • The present invention relates to acidizing treatment fluids used during hydrocarbon recovery operations, and more particularly relates, in one embodiment, to emulsified acid compositions and methods of using them to treat a subterranean formation, where the emulsified acid composition has improved thermal stability. (google.com)
  • mixture
  • Conventional acidizing fluids, such as hydrochloric acid or a mixture of hydrofluoric and hydrochloric acids, have high acid strength and quick reaction with fines and scale nearest the well bore, and have a tendency to corrode tubing, casing and downhole equipment, such as gravel pack screens and downhole pumps, especially at elevated temperatures.

  • cuticle
  • The endosperm-specific transcription factor ZHOUPI has previously been shown to play a key role in this process, by regulating both endosperm breakdown and the formation of the embryonic cuticle. (biologists.org)
  • We show that, although ABNORMAL LEAF-SHAPE1 is required for normal embryonic cuticle formation, it plays no role in regulating endosperm breakdown. (biologists.org)
  • Furthermore, we show that re-introducing ABNORMAL LEAF-SHAPE1 expression in the endosperm of zhoupi mutants partially rescues embryonic cuticle formation without rescuing their persistent endosperm phenotype. (biologists.org)
  • Thus, we conclude that ALE1 can normalize cuticle formation in the absence of endosperm breakdown, and that ZHOUPI thus controls two genetically separable developmental processes. (biologists.org)
  • We therefore provide a molecular framework of inter-tissue communication for embryo-specific cuticle formation during embryogenesis. (biologists.org)
  • carbon
  • Azelaic acid, which is a nine-carbon (C9) saturated dicarboxylic acid, has been reported in plants as a mobile signal that primes systemic defenses. (biomedcentral.com)
  • Mutation of the ECERIFERUM9 ( CER9 ) gene in Arabidopsis ( Arabidopsis thaliana ) causes elevated amounts of 18-carbon-length cutin monomers and a dramatic shift in the cuticular wax profile (especially on leaves) toward the very-long-chain free fatty acids tetracosanoic acid (C 24 ) and hexacosanoic acid (C 26 ).

  • Process
  • Acidizing wells is a conventional process for increasing or restoring the permeability of subterranean formations so as to facilitate the flow of oil and gas from the formation into the well. (google.com)
  • This process involves treating the formation with an acid to dissolve fines and carbonate scale that are plugging or clogging the pores, thereby opening the pores and other flow channels and increasing the permeability of the formation. (google.com)
