Capture and storage of carbon dioxide(CO2)from flue gas is drawing increasing interest as a potential method for the control of greenhouse gas *** liquid-based hybrid solvents are expected to retain the desired properties of ionic liquids(ILs)for CO2 capture but avoid many inherent drawbacks,such as high viscosity in their unreacted states.

Composite nanoparticles with discrete domains of different materials, which are fused by solid-state interfaces, represent an emerging class of multifunctional lab-on-a particle architectures that underpin future advances in diverse applications. This type of nanostructure combines materials with distinct physical and chemical properties to yield a unique hybrid nanosystem having multifunctional capabilities and tuned or enhanced useful properties, which may not be attainable in individual materials. Herein, we demonstrate a facile solution route for the synthesis of Pt-containing nanocomposites consisting of Ag 2 S and different noble metals. By reducing Pt and various noble metal precursors using citrate in aqueous phase in the presence of previously formed Ag 2 S nanocrystals, uniform Pt-containing Ag 2 S–noble metal heterogeneous nanostructures are obtained as the dominant product. The Pt-containing nanocomposites exhibit superior catalytic activity toward the formic acid oxidation due to the relative smaller Pt sizes and electronic coupling between semiconductor and noble metal domains.

Mechanisms investigation of coal pyrolysis will aid efficient and clean coal conversion and utilization. However, coal pyrolysis is a complex process involving myriad coupled reaction pathways such that the deeper understanding of its mechanism is still limited even with state-of-the-art experimental approaches.

The paper presents a method for monitoring CO 2 leakage in geological carbon dioxide sequestration. The unsteady state dispersion of leakage CO 2 from geosequestration simulation results showed that the ensemble trend of elevated concentration caused by CO 2 leakage can be viewed as a concentration step change perturbation to the background variation and the initial stage of dispersion process is an increasing variation. The correlation between O 2 and CO 2 variation is well linear if there is no leakage. The external linear perturbation decreases the correlation coefficient. Moreover, too large step change concentration will also reduce the average correlation coefficient. Therefore, online correlation analysis between O 2 and CO 2 in atmosphere is useful to distinguish the leakage CO 2 from complex background variation especially at the beginning of leakage occurring.

Industrial fluidized beds usually show a wide particle size distribution which significantly affects the performance of gas-solid two-phase ***,in traditional CFD models the particle size distribution is often represented by the Sauter mean diameter no matter whether the distribution is wide or narrow,which cannot reflect the effects of the particle size distribution on its operation.

The removal of S02 has received worldwide attention because SO2 as one of the major atmospheric contaminants has been causing a serious harm to the environment and human ***,flue gas desulphurization (FGD) is considered as the most effective technique to remove SO2 from the combustion of fossil fuels.1,2 However,the traditional technology,such as limestone scrubbing,produces lots of solid waste (CaSO4),and SO2 cannot be recycled.
