    摘要： A membrane structure is provided. The membrane structure includes a first layer having a plurality of interconnected pores; and a second layer disposed on the first layer. The second layer has a plurality of unconnected pores. Each of the unconnected pores is in fluid communication with at least one of the interconnected pores of the first layer. A method of making a membrane structure is provided. The method includes the steps of providing a first layer having a plurality of interconnected pores; and disposing a second layer on the first layer. Disposing a second layer includes depositing a conducting layer on the first layer; and anodizing the conducting layer to convert the conducting layer into a porous layer.

    摘要： A detection system is presented. The detection system includes a sensing component and a data analyzer. The sensing component includes a first sensor and a second sensor in fluid communication with the first sensor. The first sensor is disposed to allow operation at a predetermined temperature T1 and is selective to a first gas species at T1 and in presence of a second gas species. The second sensor is disposed to allow operation at a temperature T2 and is sensitive to the first gas species and a second gas species at T2. Temperature T2 is lower than T1. The data analyzer is disposed to receive an output signal from the sensing component and configured to calculate concentrations of the first gas species and the second gas species based on the output signal from the sensing component. A method of calculating concentrations of gas species in a gaseous mixture is also presented.

    摘要： A porous membrane for separation of carbon dioxide from a fluid stream at a temperature higher than about 200° C. with selectivity higher than Knudsen diffusion selectivity. The porous membrane comprises a porous support layer comprising alumina, silica, zirconia or stabilized zirconia; a porous separation layer comprising alumina, silica, zirconia or stabilized zirconia, and a functional layer comprising a ceramic oxide contactable with the fluid stream to preferentially transport carbon dioxide. In particular, the functional layer may be MgO, CaO, SrO, BaO, La2O3, CeO2, ATiO3, AZrO3, AAl2O4, A1FeO3, A1MnO3, A1CoO3, A1NiO3, A2HfO3, A3CeO3, Li2ZrO3, Li2SiO3, Li2TiO3 or a mixture thereof; wherein A is Mg, Ca, Sr or Ba; A1 is La, Ca, Sr or Ba; A2 is Ca, Sr or Ba; and A3 is Sr or Ba.

    摘要： A membrane structure is provided. The membrane structure includes a polymer layer having a plurality of pores; and a ceramic layer disposed on the polymer layer. The ceramic layer has a plurality of substantially unconnected pores. Each of the substantially unconnected pores is in fluid communication with at least one of the pores of the polymer layer. A method of manufacturing a membrane structure is provided. The method includes the steps of providing a polymer layer having a plurality of pores; and disposing a ceramic layer on the polymer layer. Disposing a ceramic layer includes depositing a metal layer on the polymer layer; and anodizing the metal layer to convert the metal layer into a porous layer. At least one of the depositing step and the anodizing step is performed as a continuous process. Alternatively, at least one of the depositing and the anodizing step is performed as a batch process.
