FeO_x-SiO_2 catalysts prepared by a sol-gel method were studied for the selective oxidation of methane by oxygen. A single-pass formaldehyde yield of 2.0% was o
Mesoporous silica supported CS2.5Ho.sPWI2040 catalysts were prepared by impregnation method, and several silica supports with different pore size were utilized.
Multiple performance requirements need to be guaranteed in some real-time applications such as multimedia data processing and real-time signal processing in add
The adsorption amount of poly(styrene sulfonate) and poly(dimethyldiallyl ammonium chloride) (PSS/PDDA) self-assembled multilayer membranes in designed dipping
An electromagnetic vibration was generated by simultaneously imposing a strong sta-tic magnetic field (up to 10 T) and an alternative electricity current to the
Hydrocyclones are widely used in industry, of which the geometrical design using CFD techniques is gaining more popularity in recent years. In this study, the E
In this paper, at first a new line-symmetry-based distance is proposed. The properties of the proposed distance are then elaborately described. Kd-tree-based ne
