this work is focused on synthesis of sio2- cnt hybrides via sol-gel method. homogeneous distribution of carbon nanotubes within silicon matrix was obtained by mixing the functionalized carbon nanotube (cntcooh) with active silicic acid followed by titration to the solution of sodium silicate (na2sio3) under the average temperature condition of 80?c. different ratios of multi-walled carbon nanot...

land-use change has strong effects on ecosystem properties, especially on soil carbon storage and it increased global atmospheric co2. degradation and loss of area and quality of hyrcanian forests are the biggest problems in these forests. one of the most important solutions to taking care of these problems is increasing plantations in these areas. therefore, investigation of the effects of dif...

The objective of this study is to analyze Japan’s BECCS potential. A technical assessment is used to support a policy discussion on the suitability of this mitigation tool for Japan. IIASA’s BeWhere Model is used to examine the technical potential of bioenergy including optimal locations and capacities of biomass plants. The plant locations are overlaid with a geological suitability map for car...

Deep subsurface formations (for example, high-temperature oil reservoirs) are candidate sites for carbon capture and storage technology. However, very little is known about how the subsurface microbial community would respond to an increase in CO2 pressure resulting from carbon capture and storage. Here we construct microcosms mimicking reservoir conditions (55 °C, 5 MPa) using high-temperature...

Carbon (C) storage for all the components, especially dead mass and soil organic carbon, was rarely reported and remained uncertainty in China's forest ecosystems. This study used field-measured data published between 2004 and 2014 to estimate C storage by three forest type classifications and three spatial interpolations and assessed the uncertainty in C storage resulting from different integr...
