Carbon capsules

Caldwell, H. C. Dissolution of lithium and magnesium from lithium carbonate capsules containing magnesium stearate. J. Pharm. Sci. 63 770-773. 1974. [Pg.351]

The sphere synthesis has been extended into other materials. For example, mesoporous carbon capsules[285] with hollow core and mesoporous shell structures were synthesized using submicrometer-sized solid core and mesoporous-shell silica spheres as templates. [Pg.579]

Typical nanocapsules [7] (Figure 29.1) have plane external faces as seen by high-resolution transmission electron microscopy (HRTEM), revealing the presence of several graphitic layers. At selected orientations, interlayer spacing of the carbon capsule can be measured, and strain and shell defects are identified (Figure 29.2). [Pg.833]

Nuclear applications of nanocapsules are related to the emitting physical properties of the encapsulated material. Emitted radiation can be electromagnetic of high energy (y), electrons or positrons (/3), alpha particles (" He nucleus), or fission products [67]. These emitters can be in themselves radioactive or can be activated by a nuclear reaction, usually a neutron capture. The particular advantage of carbon nanocapsules in nuclear applications is related to the protective characteristics that the carbon capsule confers to the interior product. Experiments on irradiation of fullerenes have shown that knocked carbon atoms from one cage are foimd in another fuUerene and even form dimers and trimers by a recoil-implantation mechanism [68]. The observed major damage of capsules in nanoencapsulated molybdenum irradiated in a nuclear reactor was produced by... [Pg.846]

Carbon materials have received great attention in the last decades with the emergence of nanoscience area [75]. The utilization of carbon nanomaterials also possibilities the increase on charge transfer in bioelectrochemical devices. These includes the modification of electrodes with several kinds of carbon at nanometer range carbon powder, carbon nanotubes, graphene sheets and carbon capsules [76-78]. The investigation of electronic properties of carbon nanotubes since their discovery by lijima and co-workers [79] in 1991 are one of the most reported... [Pg.37]

Various groups have reported promising EC electrode materials using hierarchical nanostructured carbons with well-organised pore structures, large specific surface areas and, particularly, an interconnected pore network. Portet et al. has reported 146 F g for zeolite-templated hollow-core mesoporous carbon s)mthesised by chemical vapor deposition (CVD) method [43]. Murali et al. has also reported hollow carbon capsules with specific capacitance of... [Pg.164]
