Graphite tailings were used as the raw materials for preparation of foamed ceramics via a high-temperature self-foaming method. The residual carbon in acted foaming agent and no additional agents required. reacted with Fe2O3 produced gas that was wrapped by liquid phase to form porous structure. effects sintering temperature, holding time, content, flux on bulk density, water absorption, mean p...

This review summarizes the microbiology and physiology of "Microthrix parvicella" and the methods of its growth control in activated sludge wastewater treatment plants. This filamentous bacterium is of high interest because of its worldwide involvement in severe bulking and foaming at wastewater treatment plants. We present a critical analysis of physiological and kinetic data on "M. parvicella...

Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...

due to the need to find new protein sources with considering the fact that the bitter vetch seed has high levels of protein content, physicochemical and mechanical properties of bitter vetch seed and functional properties of its flour were evaluated in this study. the effects of altering the ph on protein solubility, foaming capacity, foaming stability, emulsion capacity and emulsion stability ...
