The trade-off between physical adsorption capacity and selectivity of porous materials is a major barrier for efficient gas separation and purification through physisorption. We report control over pore chemistry and size in metal coordination networks with hexafluorosilicate and organic linkers for the purpose of preferential binding and orderly assembly(More)
Hollow or porous hematite (α-Fe2O3) nanoarchitectures have emerged as promising crystals in the advanced materials research. In this contribution, hierarchical mesoporous α-Fe2O3 nanoarchitectures with a pod-like shape were synthesized via a room-temperature coprecipitation of FeCl3 and NaOH solutions, followed by a mild hydrothermal treatment (120°C to(More)
With more and more network coding methods being put forward, the metric of network coding performance becomes a key issue in network coding application. In this paper, relative traffic gain (RTG) is proposed to measure the performance of network coding; it is defined as the expected value of the ratio of saved traffic flows to the sum of all traffic flows.(More)
