Abstract:
Provided are a gas separation composite membrane including a gas separation layer which is formed to include a polyimide compound on the upper side of a gas permeating support, in which the solubility of the polyimide compound in dimethylacetamide at 20° C. is 20 mg/100 g or less, and the thickness of the gas separation layer is 0.1 μm or greater and less than 5.0 μm, a method of producing the same, a gas separation module using the gas separation composite membrane, a gas separation device, and a gas separation method.
Abstract:
The magnetic tape includes a non-magnetic support; and a magnetic layer containing a ferromagnetic powder, in which, in a small-angle X-ray scattering spectrum obtained by small-angle X-ray scattering measurement of the non-magnetic support, in a region where a q-value is 0.01 to 0.10 Å−1, a ratio Imax/Imin of a scattering intensity Imax at a q-value qmax of a maximal value of a scattering intensity change rate to a scattering intensity Imin at a q-value qmin of a minimal value of the scattering intensity change rate is 2.7 or more, and qmin
Abstract:
