Abnormal Guest Diffusivity Within Pores

The single-crystal adsorbent [Rh(II)2(bza)4(pyz)]n exhibits smooth and reversible gas adsorbing ability as commonly observed in microporous media, and water vapor cannot advance in the crystal due to the hydrophobic nature of the pores (Fig. 

13) They have, however, an insufficient channel structure with a narrow neck diameter of ca. 2 A, while 02 and N2 gases are plugged in the narrow channels of inorganic materials such as Zeolite 3A and Zeolite 4A under the same condition (77 K) [15]. Some kind of pore structural changes should facilitate the passage of 

Method for the Accurate Detection and Measurement of Gas Adsorbed State 

At high pressure (9 MPa at room temperature) and low temperature (90 K) the oxygen inclusion structure is obtained [17, 18]. Oxygen molecules are coherently aligned in a linear fashion and the chain structure is most likely regulated by the channel structure. Since the observed temperature is higher than the melting point 

On the other hand, the structure of adsorbed supercritical methane (CH4) in an adsorption-desorption equilibrium state gives a methane inclusion crystal even at
