double-layer capacitors (EDLC) due to their high specific surface areas (SSA), stability, and ecological advantages. In order to make high-energy-density ACs for EDLC, petroleum pitch (PP) precarbonized at 500?1000°C in N2 gas for 1 h was used as the electrode material of the EDLC after KOH activation. As the pre-carbonization temperature increased, the SSA, pore volume and gravimetric capacitance tended to decrease, but the crystallinity and electrode density tended to increase, showing a...

High crystallinity coke-based activated carbon (hc-AC) is prepared using a potassium hydroxide solution to adsorb carbon dioxide (CO2). The CO2 adsorption characteristics of the prepared hc-AC are investigated at different temperatures. The X-ray diffraction patterns indicate that pitch-based cokes prepared under high temperature and pressure have a high crystal structure. The textural properties of hc-AC indicate that it consists mainly of slit-like pores. Compared to other textural forms of AC...

The prime objective of this research was to study the influence of hot-pressing pressure and matrix-to-reinforcement ratio on the densification of short-carbon-fiber-reinforced, randomly oriented carbon/carbon-composite. Secondary objectives included determination of the physical and mechanical properties of the resulting composite. The ‘hybrid carbon-fiberreinforced mesophase-pitch-derived carbon-matrix’ composite was fabricated by hot pressing. During hot pressing, pressure was varied from 5...

탄소/탄소 복합재의 기지를 형성시키는 방법은 화학증착법이나 액상유기물질에 함침하여 열처리하는 방법이 있다. 이중에서 용융피치를 사용할 경우, 기지의 흑연화가 가능하고 고밀도 탄소/탄소 복합재 생산이 가능한 잇점이 있다. 상압에서는 핏치의 구성성분 중 비점이 낮은 저분자량 성분이 쉽게 휘발되면서 반응계로부터 제거되지만, 가압함침은 핏치의 구성성분의 비점이 상승하며 반응계 외로 방출되지 않고, 반응계에서 다방향족 성분으로 중축합을 일으켜서 고분자화되면, 결과적으로 탄화수율의 상승과 함게 함침효율을...

a high school social studies classroom. Using a case study of an exemplary social studies teacher, Julia, this study focused on her curricular meaning making and pedagogical decision making as ways to promote global citizenship in a 9th grade social studies classroom in the United States. The findings of this study demonstrate that Julia's curricular decisions and pedagogical practices largely advocated world justice and governance and cosmopolitan notions of global citizenship, and emphasized a...
