Preparation and structure analysis of nano-iron/mesocarbon microbead composites made from a coal tar pitch with addition of ferrocene Chengyang Wang IntroductionMesocarbon microbeads (MCMB) have been used as the precursor of high-density and high-strength carbon artifacts [1][2][3][4][5], for their uniform size, excellent sphericity, self-sintering, homogeneous shrinkage and high yield of

A Novel Bifunctional Self‐Stabilized Strategy Enabling 4.6 V

Moreover, the long‐term cyclability of CMLCO/mesocarbon microbeads full cells is also enhanced significantly even at high temperature of 60 C. The synergistic effects of this bifunctional self‐stabilized strategy on structural reversibility and interfacial stability are demonstrated by investigating the phase transitions and interface characteristics of cycled LiCoO 2 .

Anodes for the Electrolytic Production of Nitrogen

In contrast, due to the nature of the mesocarbon microbeads, the mesocarbon microbeads may self-sinter at low temperatures (e.g., about 400-600 C.). Self-sintering means the microbeads are pressed and fused together and sintered or heated, but require no binders, resins, fillers, or the like in order to mold and sinter the anode part.

(PDF) ACTIVATED MONOLITHS BASED ON

Because mesophase-based materials have self-sintering ability, these materials are good candidates to produce monoliths of activated carbon of high surface area without using a binder [13, 14]. In this paper we present the effects induced by the chemical activation and the processsing conditions on the structure of activated carbon monoliths based on carbonaceous mesophase.

The self-diffusion coefficient of n-octadecane molecule increases significantly with the increase of temperature. When the temperature increases from 253 K to 283 K, the self-diffusion coefficient gradually increases from 0.951 nm 2 /ns to 1.526 nm 2 /ns, while in the range of 293-313 K, the self-diffusion coefficient significantly increases from 1.655 nm 2 /ns to 3.356 nm 2 /ns.

Mesocarbon microbeads (MCMBs) are attractive precursors for high-density, high-strength polycrystalline graphite due to their self-sintering capability. They have the shape of a standard sphere and stack in a completely random orientation during compaction, thereby leading to an isotropic texture.
