Highly ordered mesoporous carbon (OMC) materials have attracted much attention in many fields including catalysis, adsorption and energy storage, due to their high porosity, high surface area and controllable regular pore-structure [1-6]. Successful synthesis pathways for obtaining OMC materials include the direct synthesis of OMC materials through the organic-organic self-assembly method (soft templating process) and nano-replication of OMC materials from mesoporous silica templates (hard...

As a replacement for activated carbon, biochar was synthesized and used for the adsorptive removal of formaldehyde and nitrogen oxide. Biochar was produced from the fast pyrolysis of the red marine macro alga, Pyropia tenera. The P. tenera char was then activated with steam, ammonia and KOH to alter its characteristics. The adsorption of formaldehyde, which is one of the main indoor air pollutants, onto the seaweed char was performed using 1-ppm formaldehyde and the char was activated using a...

Three activated carbons (ACs) were prepared using NaOH (N) as an activating agent. Hydrofluoric acid pre-leached rice husk was used as a precursor. After leaching, the precursor was washed with distilled water, dried, crushed, and then sieved; a size fraction of 0.3-0.5 mm was selected for carbonization in the absence of air at 600°C. The carbonization product (LC) was mixed with NaOH at ratios of 1:2, 1:3, and 1:4 (wt of LC: wt of NaOH) and the produced ACs after activation at 800°C were...

to conduct the evaluation of long-term performance of BMPs. The financial data such as actual construction, design and maintenance cost were also collected to evaluate the lifecycle cost (LCC) of BMPs. In this study, most of the maintenance activity was focused in the aesthetic maintenance that resulted to the annual maintenance cost of the four BMP types was closely similar ranging from 8,483 $/yr for retention pond to 8,888 $/yr infiltration system. The highest LCC were observed in constructed...

본 연구에서는 물이용특성을 평가할 수 있는 세부지표 및 주제별 중간지수를 과거자료 분석과 요인분석을 통하여 선정하 고 주제접근방식의 구성체계로 구성하였다. 또한 이를 종합하여 유역의 물이용 특성을 평가할 수 있는 통합지수(이수취약 성지수)를 개발하였다. 개발된 지수를 이용하여 1990년부터 2007년까지의 유관기관의 자료를 활용하여 북한을 제외한 812 개의 표준유역에 대해 물이용 특성을 평가하였다. 지표산정에 있어 여러 표준화 및 가중치부여 방법 중 타당한 방법을 찾고자 민감도 분석을 실시하였으며 개발된 지표의...

본 연구에서는 NOAA CPC에서 제공하고 있는 인공위성을 이용한 광역적 강수량 추정 자료인 CMORPH와 지상 관측자료 와의 비교를 통해 위성으로부터 유도된 강수자료의 정확도 및 활용 가능성 등 수자원 분야 이용 가능성을 분석하는 것을 목적으로 하였다. 2002-2011년의 10년간의 자료를 분석한 결과 1일 누가강수의 상관계수가 평균0.87 정도로 분석되었으나, 연간 총강수량은 약 4～5배 정도 차이가 나는 것으로 분석되었다. 또한 시간해상도가 커짐에 따라 RMSE의 변동성이 작 아지는 것으로 분석되었다. 유역 규모에 따른 분석에서...
