Summary: A soft nanoporous crystal has been developed that can separate propyne/propylene mixtures by sieving. This occurs by the rotational movement of pyridyl rings within this framework creating a pore with a maximum size of 4.4 angstrom, thereby facilitating the adsorption of propyne while completely excluding propylene.

Summary: Utilizing different solvents, self-assembly of N,N,N',N'-tetrakis(4-carboxyphenyl)-1,4-phenylenediamine results in isostructural hydrogen-bonded organic frameworks. The reversible hydrogen-bond-to-hydrogen-bond transformation between HOF-30 and HOF-30a has been revealed through single-crystal and powder X-ray diffraction, with HOF-30a showing selective adsorption of propyne over propylene. The preferred location of propyne in HOF has also been identified by SCXRD test.

Summary: The conversion of wetlands to aquaculture ponds alters phosphorus (P) cycling and its budget balance, leading to increased P release into water and exacerbating water quality degradation and eutrophication in coastal areas. This study investigates the availability and mobilization mechanisms of P in natural coastal wetlands and converted aquaculture ponds using advanced techniques, revealing that the conversion weakens the dependence of sediment P mobilization on iron and sulfur reactions. The findings emphasize the urgent need for specific actions to alleviate internal P-loading in aquaculture.

Summary: Developing adsorptive separation processes using C2H6-selective sorbents is a promising alternative for energy-intensive cryogenic distillation in C2H4 purification. Our study showed that Ni-MOF 2 exhibited significantly higher performance in C2H6/C2H4 separation compared to Ni-MOF-1. The unique aromatic pore surfaces and suitable pore spaces of Ni-MOF 2 contribute to its high C2H6 uptake capacity, making it one of the best porous materials for this gas separation. It can generate 12 L kg(-1) of polymer-grade C2H4 product from equimolar C2H6/C2H4 mixtures at ambient conditions.
