  • Patent number: 10008700
    Abstract: A packaging material 1 includes a heat resistant resin stretched film layer 2 as an outer layer, a thermoplastic resin layer 3 as an inner layer, a metal foil layer 4 arranged between these layers, and a colored ink layer 10 arranged between the metal foil layer 4 and the heat resistant resin stretched film layer 2. As the heat resistant resin stretched film, a heat resistant resin stretched film having a hot water shrinkage rate of 2% to 20% is used, and the heat resistant resin stretched film layer 2 and the colored ink layer 4 are integrally laminated via an easily adhesive layer 30. In this packaging material, at the time of forming and sealing, and even being used in a somewhat severe environment such as high-temperature and humid environment, the colored ink layer will not be detached from the heat resistant resin stretched film layer.

  • Patent number: 9694055
    Abstract: The invention is directed to methods of inducing cell recruitment and tissue regeneration at a target site in a subject. It is also based, in part, on the discovery that a subject's own biologic resources and environmental conditions can be used for in situ tissue regeneration and thereby reduce or eliminate the need for donor cell procurement and ex vivo manipulation of such donor cells. Methods are disclosed for recruitment of a subject's own stem cells to a target region by inducing a sustained positive pressure at a target site, such as the kidney, thereby increasing the number of pluripotent cells capable of differentiating to regenerate the target tissue.

  • Patent number: 8283385
    Abstract: Reversible switchable surfactants are provided. A surfactant is the salt of an amidine or guanidine: having at least one R group that is a hydrophobic moiety selected from the group consisting of higher aliphatic moiety, higher siloxyl moiety, higher aliphatic/siloxyl moiety, aliphatic/aryl moiety, siloxyl/aryl moiety, and aliphatic/siloxyl/aryl moiety. The other R groups are smaller moieties such as H, C1 to C4 aliphatic or the like. The surfactant is turned on by a gas that liberates hydrogen ions, such as, for example, carbon dioxide, which liberates hydrogen ions in the presence of water. The surfactant is turned off by exposure to a flushing gas and/or heating. When “on” the surfactants are useful to stabilize emulsions, and when “off” they are useful to separate immiscible liquids or a liquid and a solid. The surfactants find uses in polymerization and in the oil industry.

  • Patent number: 8211949
    Abstract: Novel mixtures of long-chain (C10-C20) olefins are functionalized by conversion to aldehydes using an OXO process, or to sulfates, sulfonates, sulfones, sulfides, or sulfoxides by direct sulfonation. The aldehydes may then be hydrogenated to form alcohols, or aminated to form amines or amides. The olefins starting mixture may be acquired as a byproduct of the tetramerization of ethylene in the presence of certain chromium-containing tetramerization catalysts. The functionalized mixtures, and derivatives prepared therefrom such as alkoxylates prepared from the alcohols, may be useful as surfactants that may offer improved performance in many applications, while their preparation based on a byproduct mixture reduces their cost and also reduces waste-handling issues for this non-targeted stream.

  • Patent number: 7179328
    Abstract: An aqueous solution for treatment of colored concrete, glazed enamel or porcelain surfaces to increase the coefficient of friction of that surface, whether dry or wet, to about 0.8 without deteriorating the color of the surface comprises about 1.5 to 1.9 wt % of ammonium bifluoride, 1.5 to 3.0 wt % of tri-ethylamine and a wetting agent in water. The degree of change of the color of the surface, treated seven minutes with the solution of the current application, measured by a color meter shows only 0.56 while the result of a commercial solution to increase the frictional coefficient shows 2.22. This means that the color change by the solution of the current application is undetectable by human eyes. Meanwhile, the change by the commercial solution product is detectable.
