Abstract: A method for making a magnetic-nanoparticle-supported catalyst includes reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a phosphine group, an amine group and at least one hydroxyl group; anchoring the ligand to a surface of magnetic nanoparticles via an oxygen atom of the hydroxyl group to form a ligand complex; combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-particle-supported catalyst. The magnetic-particle-supported catalyst is a Rh complex of magnetic-Fe3O4-nanoparticle-supported ferrocenyl phosphine catalyst.

Abstract: Aspects of the present disclosure are presented for a third party content recommendation platform to provide a publisher the ability to target web users, who have visited the publisher's website(s), with the publisher's advertisements when the web user visits other web sites within an affiliated network of the third party content recommendation platform.

Abstract: Aspects of the present disclosure are presented for advertisers in e-marketing campaigns to specify with greater granularity and control where and on what websites their advertisements may be placed on publisher websites, through a third party advertising platform. The advertisers utilizing this functionality may be able to improve their advertising effectiveness by having more control, such as eliminating placement of ads that have been shown to generate poor marketing results, or increasing placement onto websites that have been shown to have effective marketing results. The third party advertising platform may place the control directly with the advertiser, allowing the advertiser to specify which websites and where in the websites the widgets should be placed without needing to coordinate with the third party advertising company.
