A novel low density two-fold interpenetrated MOF-5 analogue with pcu topology, JUC-100, was designed and prepared successfully. It can be regarded as in which half of the Zn4O(CO2)6 units are replaced by organic 1,3,5-triphenylbenzene segments. JUC-100 exhibits H2 uptake ability comparable to MOF-5, but relatively initial isosteric heat adsorption.

ABSTRACT The existence of strong random noise in surface microseismic data may decrease the utility these data. Non‐subsampled shearlet transform can effectively suppress by properly setting a threshold to non‐subsampled coefficients. However, when signal‐to‐noise ratio is low, coefficients related are very close associated with signals domain that will be retained and treated as signals. Therefore, we need minimise overlapping before thresholding. In this paper, singular value decomposition...
