20130011492 | ELECTROCHEMICAL DEPOSITION OF NOBLE METAL AND CHITOSAN COATING - A method of electrochemical deposition includes submerging a stainless steel surface of an object in a chitosan solution and applying a first electric potential between the submerged stainless steel surface and the chitosan solution for a predetermined time to form a chitosan surface coating. After rinsing and dehydrating, the chitosan coated surface is submerged in a solution having a predetermined concentration of a noble metal nitrate and a second electric potential is applied between the chitosan coated surface and the solution of the noble metal nitrate to deposit noble metal particles on the chitosan surface coating. | 01-10-2013 |

20150014180 | ELECTROCHEMICAL SYNTHESIS OF NITRO-CHITOSAN - The present disclosure provides methods for producing chitosan derivatives and the derivatives formed by these methods. The processes of the present disclosure utilize electrochemical methods to functionalize and/or modify amine and/or hydroxyl groups present on chitosan, to form new derivatives. In embodiments, a nitro-chitosan derivative may be prepared. The altered cationic affinity of these derivatives make them excellent candidates for environmental applications, including water and waste treatments, and fertilizers. | 01-15-2015 |

20130022471 | METHODS FOR REPAIRING A TURBINE AIRFOIL CONSTRUCTED FROM CMC MATERIAL - Methods for repairing a turbine airfoil constructed from a CMC material are provided via filling a cavity located in the turbine airfoil with a ceramic paste (e.g., including a ceramic powder and a binder), heating the ceramic paste in the cavity to remove the binder, thereby forming a porous ceramic material, and adding a molten ceramic material to the porous ceramic material. The cavity can be defined in an airfoil of the turbine airfoil (e.g., on a tip or cap of the airfoil). Intermediates formed during the repair of a turbine airfoil are also provided. The intermediate can generally include an airfoil comprising a CMC material, a cavity defined in the airfoil, and a porous ceramic material filling the cavity. | 01-24-2013 |
20130062000 | METHOD FOR MODIFYING COMPOSITE ARTICLES - In certain embodiments of the present disclosure a method for modifying a composite article is described. The method includes positioning a plug made from composite material at a site on the composite article. The method further includes rotating at least one of the plug and the article at a rate of speed sufficient to form an inertia bond between the plug and the site of the composite article. The plug and the site are engaged to effect an inertia bond therebetween. | 03-14-2013 |

20140033868 | Method For Extraction And Separation Of Lanthanoid Elements And Actinoid Elements, And Means For Extraction And Separation Of Lanthanoid Elements And Actinoid Elements - Problem: To provide a material and a method for efficient and inexpensive extraction of rare metals that are included in urban minerals. Solution: A method for the extraction of lanthanoid elements and actinoid elements, said method comprising: an adsorption process wherein a metal-dissolved solution containing a target metal selected from lanthanoid elements and actinoid elements is made to come into contact with porous structures that carry metal-adsorbent compounds that are adsorbent to target metal ions so that the target metal ions in said solution are adsorbed by said metal-adsorbent compounds; and a target metal separation process wherein said porous structures are made to come into contact with a back-extraction solution so that the target metal ions that are adsorbed by said metal-absorbent compounds are transported to the back-extraction solution. | 02-06-2014 |

20130036870 | METHOD FOR COLLECTING Co FROM URBAN ORE - Urban ore is a mixture of a lot of metallic elements, and these metallic elements need to be separately collected therefrom. However, because the content of each metallic element is very small, it has been extremely difficult to selectively collect the required metallic element. | 02-14-2013 |
