Immobilizing biocomponents on solid surfaces is a critical step in the development of new devices for future biological, medical, and elec- tronic applications. Therefore, numerous integrated films were recently developed by immobilizing different proteins or enzymes on electrode surfaces. In this work, hemeproteins were safely immobilized onto macroporous nickel-based electrodes while maintaining their functionality. Such modified electrodes showed interesting pseudo-capacitive behavior. Among hemeproteins, hemoglobin （Hb） film has a higher electro- chemical performance and greater charge/discharge cycling stability than myoglobin （Mb） and cytochrome C （CytC）. The heme group in an alkaline medium could induce the formation of superoxides on the electrode surface. These capacitive features of hemeprotein-Ni electrode were related to strong binding sites between hemeproteins and porous Ni electrode, the accumulation of superoxide or radicals on the Ni sur- face, and facile electron transfer and electrolyte diffusion through the three-dimensional macroporous network. Thus, these new protein-based supercapacitors have potential use in free-standing platform technology for the development of implantable energy-storage devices.

Single-phase Y_(4)Al_(2)O_(9)(YAM)powders were synthesized via solid-state reaction starting from nano-sized Al_(2)O_(3) and Y_(2)O_(3).Fully dense(99.5%)bulk YAM ceramics were consolidated by spark plasma sintering(SPS)at 1800℃.We demonstrated the excellent damage tolerance and good machinability of YAM *** properties are attributed to the easy slipping along the weakly bonded crystallographic planes,resulting in multiple energy dissipation mechanisms such as transgranular fracture,shear slipping and localized grain crushing.

Synthesis of functional nano-structured powders has been developed through reactive thermal plasma *** discharge,which is the so-called thermal plasma,proves to be a useful tool in the synthesis and surface modification of a wide range of metals and inorganic *** advantages as reaction fields are as follows;(1) Thermal plasmas have quite high temperatures(up to<15000K).As the plasmas are generated at relatively high pressures(close to the atmospheric pressure),they have large densities and are considered to be at equilibrium(local thermal equilibrium).That is,the temperatures of heavy particles(such as atoms,molecules, and ions) are almost equal to that of the light species(that is,electrons);(2) High concentrations of chemically reactive radicals enhance the reactivity of the thermal plasmas;(3) Superfast quenching(<10 to<10K/s) takes place in the plasma tail flame region.
