Abstract: In some examples, an article may include a carbon-carbon composite, an antioxidant in pores in a surface of the carbon-carbon composite, and a hydrophobic coating on the surface. The hydrophobic coating includes an oxide of a metal. The metal has a Pauling electronegativity of less than about 1.7. In some examples, the article may be a carbon-carbon composite brake disk that includes a carbon-carbon composite substrate defining a friction surface and a non-friction surface. The antioxidant may be a phosphate-based antioxidant, and the antioxidant may be in pores in the non-friction surface. In some examples, the hydrophobic coating is on the non-friction surface over the phosphate-based antioxidant. In some examples, the hydrophobic coating may include a majority of at least one of yttrium oxide, scandium oxide, or zirconium oxide.

Abstract: A new cultivar of Phygelius named ‘YAPCOR’ that is characterized by a compact well-branched habit, burgundy stems and deep coral-pink pendulous flowers. In combination these traits set ‘YAPCOR’ apart from all other existing varieties of Phygelius known to the inventor.

Abstract: In the synthesis of 1,1,1,3,3-pentafluorobutane (R-365mfc), a mixture of R-365mfc and the impurity 1,1,1,3-tetrafluoro-2-butene (R-1354mzy) is purified and R-1354mzy is removed from the mixture by contacting the mixture with 1-5 mols of chlorine for each mol of R-1354mzy in the presence of ultraviolet light having a wavelength between about 300 to 400 nm which provides at least 0.02 watts-hour/kg of the mixture. The R-1354mzy is reduced to below 10 wt. ppm as it is converted to 2,3-dichloro-1,1,1,3-tetrafluorobutane (R-354) or other butane containing more chlorine and having a higher boiling point than R-365mfc. The butane(s) may be separated more easily from R-365mfc. The photochlorination is effected in a manner such that at least about 96 weight percent of the starting amount of R-365mfc is maintained in the mixture.

Abstract: A gas adsorbent system includes a molded gas adsorbent within a housing. The molded gas adsorbent is disposed in the housing so that shifting is prevented without adhering the gas adsorbent to the housing, for example, by completely filling the housing. The gas adsorbent may include activated zeolite 13X. The gas adsorbent may be formed from a polymer solution such as polysulfone, and contain an organic binder.

Abstract: In the synthesis of 1,1,1,3,3-pentafluorobutane (R-365mfc), a mixture of R-365mfc and the impurity 1-chloro-3,3,3-trifluoropropene (R-1354zd) is purified and R-1354zd is removed from the mixture by contacting the mixture with 1-5 mols of chlorine for each mol of R-1354zd in the presence of ultraviolet light having a wavelength between about 300 to 400 nm which provides at least 0.02 watts-hour/kg of the mixture.

Abstract: A method of making a gas adsorbent comprises dissolving a polymer in one or more first solvents to form a polymer solution; mixing an inorganic adsorbent with the polymer solution to form a precursor; molding the precursor; and leaching the first solvents from the precursor with a second solvent.
