摘要:
A thermosensitive nanostructure for hyperthermia treatment. Magnetic nanoparticles are encapsulated in a thermosensitive polymer nanostructure having a lower critical solution temperature (LCST) of about 40-45° C. The thermosensitive polymer nanostructure may carry a drug. When the magnetic nanoparticles are heated to 40-45° C. by application of an alternating magnetic field in hyperthermia treatment, the thermosensitive polymer nanostructure collapses to release the drug, thus providing concurrent drug treatment.
摘要:
A novel Group IV elements-bridged metallocene complex is disclosed which is represented by the following formula (I): wherein R and R1 are different and are independently selected from the group consisting of &eegr;5-cyclopentadienyl group, substituted &eegr;5-cyclopentadienyl group, indenyl group, and fluorenyl group; R2 is selected from the group consisting of —N(CH3)2, —N(C2H5)2, halogen, alkoxy, —(C═O)NH2, and C6-12 hydrocarbyl group; M is a Group IVA element; and M1 is a Group IVB metal. When employing the metallocene complex to prepare olefin polymers, since it is bridged by a Group IV element, there are two catalytic sites in the single metallocene complex catalyst. Therefore, the olefin monomers can be polymerized to a bimodal olefin polymer by a single catalyst in a single reactor, resulting in lowered capital costs.
