Magnetic encapsulation

Other imaging techniques such as magnetic resonance and ultrasound have opened up avenues of tremendous potential for contrast medium enhancement (123). Ultrasound contrast media developments have centered around encapsulated air micro-bubbles. Magnetic resonance contrast agents iavolve metal—ligand complexes and have evolved from ionic to nonionic species, much as radiopaques have. 

Magnetic reed contacts are glass-encapsulated magnetically operated reed switches used on doors and windows. The contacts can be overcome by cutting the door, leaving the magnet undisturbed. 

Finally, we also mention a cobalt ring (37), and the non-magnetic ring Zn C [Zn(hmp)2]6 2+ analogue (38), in which hmp is 2-hydroxymethyl-pyridine. A central octahedral Zn2+ ion is encapsulated in a hexanuclear ring.

Stone et al. use this method to simultaneously synthesize the silica and entrap the butyrylcholinesterase which retains all its activity after the process of encapsulation, a high enzyme loading (90 %) is reached and the stability is increased [168]. The method has been further developed to simultaneously entrap catalase and horseradish peroxidase with inorganic magnetic nanopartides [169] which will fadlitate the separation [170,171].

SCO Cationic Complexes Encapsulated in Magnetically Coupled Anionic Networks... 

While the encapsulation of SCO cations within anionic networks needs further development, particularly by use of cations having abrupt SCO transitions, the results to date show that the cationic and anionic networks remain independent, magnetically, with little cooperativity being evident. 

The present status of attempts to encapsulate SCO complex cations in magnetically coupled anionic frameworks was described in Sect. 3. To date, there is no evidence for magnetic or cooperative interactions between cation and host network, for the anionic oxalato or dicyanamido types.

Endohedral doping (encapsulation) of other materials within carbon nanostructures can be carried out by nano-capillary effects or during synthesis (Fig. 4.3(b)). A great variety of halides, oxides, metals and alloys have been encapsulated within CNTs [36-41]. When transition metals are encapsulated, the entire sample can exhibit high magnetic coercivities ca. 0.22 T [42,43]. The encapsulation of C60 molecules can also be accomplished and if the material is heat treated at high temperatures...
