Hierarchically Porous Carbon Plates Derived from Wood as
Porous carbon electrodes have emerged as important cathode materials for metal–air battery systems. However, most approaches for fabricating porous carbon electrodes from biomass are highly energy inefficient as they require the breaking down of the biomass and its subsequent reconstitution into powder‐like carbon.

A sheet like porous carbon for high rate supercapacitors
Herein, a sheet like porous carbon is prepared by a carbonization of an eggplant (Fig. 1a), which is chosen as the carbon precursor because of its inherent sheet like structure on microscale (as shown in the scanning electron microscopy (SEM) image in Fig.

portion houses the porous carbon gas delivery system and the static and dynamic plates. The dynamic plate is suspended from the upper portion of the test rig by four turnbuckle style rods and brackets. These rods are designed to level and maintain parallelism between the static and dynamic plates. Figure 4 shows the design of the turnbuckle assembly:
Researchers create first carbon fibers with uniform porous
Researchers create first carbon fibers with uniform porous structure. Conventional (A, B) and new (C) methods for synthesizing carbon fibers from various polymer precursors. (A) Pure PAN is electrospun into a fiber mat, oxidized at 280 °C in air to crosslink PAN (blue), and then pyrolyzed at 800 °C in N2 to generate carbon fibers (grey).

Porous Carbon Materials as Supreme Metal Free Counter
To fabricate the integrated pure carbon electrode, porous carbon plates (PCPs) were firstly prepared by a bulk molding carbonization process using cheap coal powder as precursor. The permeation of electrolyte through the porous substrate has been fairly resolved by impermeable pretreatment through a repeat pitch impregnation carbonization treatment of paraffin protected PCPs.
Thermal characterization of porous carbon
Porous carbon foam developed at Oak Ridge National Laboratory (ORNL) [1,2] is being investigated as a material to improve single and multiphase heat transfer. Carbon foam has a high effective conductivity (40– 160 W/m K) [2] because of the high material conductivity of the graphitized carbon material (800–1900 W/m K). In
