Microbial fuel cells (MFC) are bioelectrochemical systems designed to convert the chemical energy contained in organic matter into electrical energy utilizing catalytic (metabolic) activity of microorganisms. The fabrication of novel carbon materials as anodes to generate power without the utilization of noble metals is a hot-spot in the research of MFC. In the present work, silver grass (Miscanthus sinensis) has been used as an anode material for achieving higher power density and to remove heavy metals (Cr, Co and Cu) from contaminated wastewater through microbial fuel cell. The biomass carbon powder obtained from silver grass exhibited high specific area (2700 m2 g-1) with excellent porous structure which facilitates the growth of bacteria (E. Coli) during the MFC operation and resulted in delivering high power output with the decontamination of contaminated waste water by removing the heavy metals.

Multifunctional Fe-aminoclay/carboxymethyl cellulose/polyhedral oligomeric silsesquioxane composite (FeAC/CMC/POSS) with layered structure was successfully synthesized and utilized as adsorbent for the removal of cesium ions (Cs+) and cationic dyes methylene blue (MB) and chrysoidine G (CG). The FeAC/CMC/POSS exhibit excellent adsorption capacities for Cs+ ions, MB and CG of 152, 438 and 791 mg g-1, respectively. The unprecedented adsorption capacities for Cs+ ions, MB and CG may be attributed to (i) the layered morphology of the composite and-NH2 groups on clay surface; (ii) existence of-COO-and-OH- groups on the CMC backbone. More importantly, the incorporation of POSS increases the interlayer spacing of Fe-aminoclay providing room for the encapsulation of Cs+ ions and dye molecules. Owing to superior adsorption capacity, the devised FeAC/CMC/POSS composite could be a promising organic-inorganic material used to cost-effectively remove the multitude of environmental pollutants.

This study has been carried out find the thermal performance and operating characteristics comparison of singular evacuated tubular solar collector(ETSC) using different working fluid. Three sets having different evacuated tubular solar collector with heat pipe working fluids Water, Ethanol, MA were investigated in the same operating condition for a indoor experiment equipment. First the result of working fluid using water showed that F R(τα) was 0.6636 and F RU L was -1.8457. second working fluid using ethanol showed that F R(τα) was 0.6147 and F RU L was -0.6365. Finally when working fluid using MA's occasion that non-condensable gas does not happen F R(τα) was 0.6572 and F RU L was -2.0086.

In this study, thermal performance test of VMD module was performed, prior to the construction of the demonstration plant using the vacuum membrane distillation (VMD) module of the capacity of 400 m3/day and to the commercialization of the VMD module. For the thermal performance test, the experimental equipment of capacity of 2 m3/day was constructed. The permeate flux test and thermal performance test according to feed water conditions such as temperature and flow rate were conducted. The VMD module used in the study was manufactured by ECONITY Co., LTD with PVDF hollow fiber membrane. As a result, the Performance Ratio (PR) of the VMD module showed the maximum value of 0.904 under the condition of feed water temperature of 75℃ and flow rate of 8 m3/h. PR value of the VMD module using PVDF hollow fiber membrane showed linearly increasing relationship with feed water temperature and flow rate. Also, The permeate flux of the VMD module was analyzed to have maximum value of 18.25 LMH and the salt rejection was 99.99%.

This study was carried out to evaluate thermal performance of the renewable hybrid heat supply system with solar thermal system and wood pellet boiler for Zero Carbon Green home of apartment houses. The hybrid heat supply system was set up at Korea Institute Energy Research in 2011. The system was comprised of the wood pellet boiler unit with heat capacity designed as 20,000 kacal/hr, a evacuated tubular solar collector 3.74 m2 of aperture area at the 20º install angle, a 0.3 m2 hot water storage tank, a 0.15 m2 hot water storage tank for space heating. Thermal performance tests for one-house of apartment house were carried out by hot water load and heating load in winter season through the hybrid heat supply system. As a result, hot water energy supplied by the hybrid heat supply system was 11kWh in a day. Solar thermal energy portion was 2.99kWh which is 27% of the total hot water energy supply, wood pellet boiler supply portion was 8.017kWh which is 73% of the total hot water energy supply.
