Classical ceramic NTC resistors composed of spinel structure (MMn2O4, where M=Ni, Co, Fe, Cu, Zn) show aging of the electrical properties and their application is commonly limited to temperatures below 300°C.

Liposomes:
Liposomes are self-assembling, spherical structures composed of lipid bilayers with an aqueous central core.
Cavities in the core structure and folding of the branches create cages and channels [26].
Micelles are amphiphilic spherical structures formed from the self-assembly of biocompatible amphiphilic block copolymers having a hydrophobic core and a hydrophilic shell [16].
Fullerenes Fullerenes are a family of carbon allotropic compounds that were predicted to exist in 1970 and officially discovered in 1985 by Robert Curl, Harold Kroto and Richard Smalley for which they received the Nobel prize in chemistry [34].

The Co grains in the films show hcp
structure with (11 20) preferred orientation.
Probably this peak is attributed to the (220) plane of Co phase in fcc structure or (11 2 0) plane of hcp structure.

For the Ce0.5Zr0.5O2 solid solutions, the XRD lines are rather similar to those corresponding to pure ceria (face-centered cubic and fluorite structure, JCPDS 34-0394).
Phase Transformation From Fluorite To Pyrochlore Structure In Ce0.5zr0.5o2 During Thermal Treatments In Reduction Atmosphere.
The cation ordering along <110> is a distinguishing feature for the Ce2Zr2O7 pyrochlore structure compared to the fluorite structure CeO2 (Figure 7).
Reduction treatment of Ce0.5Zr0.5O2 causes a phase transformation, instead of phase separation, from fluoride to pyrochlore structure, suggesting nanoscale compositionally homogeneity of particles.
