The development of nanostructured functional materials derived from biomass and/or waste is of growing importance for creating sustainable energy-storage systems. In this study, nanoporous carbonaceous materials containing numerous heteroatoms were fabricated from waste coffee grounds using a top-down process via simple heating with KOH. The nanoporous carbon nanosheets exhibited notable material properties such as high specific surface area (1960.1 m2 g?1), numerous redox-active heteroatoms... -

We report the preparation of sulfonated reduced graphene oxide (SRGO) by the sulfonation of graphene oxide followed by radiation-induced chemical reduction. Graphene oxide prepared by the well-known modified Hummer's method was sulfonated with the aryl diazonium salt of sulfanilic acid. Sulfonated graphene oxide (SGO) dispersed in ethanol was subsequently reduced by γ-ray irradiation at various absorbed doses to produce SRGO. The results of optical, chemical, and thermal analyses revealed that... -

갯벌이나 연안습지의 생태구조 및 생지화학적 물질 순환을 이해하기 위해서는 유기물 분해기능 평가 및 분해경로에 대한 연구가 필수적으로 진행되어야 함에도 불구하고 국내에는 이에 대한 연구가 거의 없다. 본 논문에서는 하계 강화도 남단의 갯벌에서 미생물에 의한 혐기성 유기물 분해정도를 파악하고, 황산염 환원을 통한 유기물 분해경로의 정량적 중요성을 평가하고자 하였다. 유기물 분해율은 깊이 6 cm 이내에서 41.9~89.4 mmol m-2 d-1의 범위로 나타났으며, 이를 강화도 갯벌의 전체 적(약 300 km2)으로 환산할 경우, 하루에... -
