摘要： A system for recovery of metals from solutions containing dissolved metals. The system includes an apparatus and method for placing supercritical carbon dioxide that contains an extractant in contact with the solution and agitating the two resulting phases. Once the metals are extracted by the extractant, they can be removed from the carbon dioxide phase by depressurization or by reduction by exposure to hydrogen. The extractant preferably comprises a metal binding group, a spacer group and a C02-philic group.

摘要： A method for coating a metal surface, comprising: applying a solution comprising an amide thiol compound and a solvent to a metal surface, allowing the thiol compound to self assemble on the surface, and removing excess thiol compound from the surface. The amide thiol compound is preferably a fluoralkyl amide thiol and more preferably one having the general formula F(CF2)nCONH(CH2)nSH, where n and m are each 2-20. The solution can be sprayed onto the metal surface, or the metal surface can be dipped into the solution. The surface should be kept wet for a time period sufficient to allow the thiol molecules to self assemble on the metal surface.
摘要翻译：一种涂覆金属表面的方法，包括：将包含酰胺硫醇化合物和溶剂的溶液施加到金属表面，允许硫醇化合物在表面上自组装，并从表面除去过量的硫醇化合物。酰胺硫醇化合物优选为氟烷基酰胺硫醇，更优选具有通式F（CF 2）nCONH（CH 2）nSH的化合物，其中n和m各自为2-20。溶液可以喷涂到金属表面上，或者金属表面可以浸入溶液中。表面应保持湿润一段时间，足以使硫醇分子自动组装在金属表面上。
