“…When the C 3 H 6 /C 2 H 4 ratios were changed to 10/25 and 4/36 at 298/273 K, the collected high-purity C 2 H 4 were calculated to be 182.4/242.0 and 323.4/531.9 L kg À 1 , respectively. These productivities are significantly higher than those of [Zn 2 (oba) 2 (dmimpym)] (94.9 L kg À 1 ), [25] Mn-dtzip (109.6 L kg À 1 ), [10] iso-MOF-4 Angewandte Chemie (320.3 L kg À 1 ), [3a] and Zn-BPZ-SA (51.5 L kg À 1 ) [28] under the same conditions.…”

“…TJT-100 (1.2), [9d] NPU-2 (1.52), [13] Azole-Th-1 (1.46), [14] and JNU-2 (1.5). [12b] The selectivities for C 3 H 6 /C 2 H 4 (v/v, 1/1, 2/5, and 1/9) mixtures were calculated to be about 7.4/9.7, 8.6/11.5, and 8.9/12.4 at 298/273 K, respectively (Figure 3b and S19), which are superior to the current outstanding materials for C 3 H 6 /C 2 H 4 separation (Figure S20), such as HKUST-1 (5.8), [20] Mn-dpzip (8.6), [10] spe-MOF (7.7), [21] and UPC-33 (9.5). [22] The separation potential (ΔQ = q 1 ×y 2 /y 1 -q 2 ) as a combined capacity-selectivity metric introduced by Krishna was utilized here for further comprehensively evaluating the separation performance.…”

Herein, a 2‐fold interpenetrated metal‐organic framework (MOF) Zn‐BPZ‐TATB with accessible N/O active sites in nonpolar pore surfaces was reported for one‐step C2H4 purification from C2H6 or C3H6 mixtures as well as recovery of C3H6 from C2H6/C3H6/C2H4 mixtures. The MOF exhibits the favorable C2H6 and C3H6 uptakes (> 100 cm3 g‐1 at 298 K under 100 kPa) as well as selective adsorption of C2H6 and C3H6 over C2H4. The C3H6‐ and C2H6‐selective feature were investigated detailedly by experimental tests as well as sorption kinetic studyies. Molecular modelling revealed the multiple interactions between C3H6 or C2H6 molecules and methyl groups as well as triazine rings in pores. Zn‐BPZ‐TATB not only can directly generate 323.4 L kg‐1 and 15.4 L kg‐1 of high‐purity (≥99.9%) C2H4 from C3H6/C2H4 and C2H6/C2H4 mixtures, but also provide a large high‐purity (≥99.5%) C3H6 recovery capacity of 60.1 L kg‐1 from C3H6/C2H4 mixtures. More importantly, the high‐purity C3H6 (≥99.5%) and C2H4 (≥99.9%) with the productivities of 38.2 and 12.7 L kg‐1 can be simultaneously obtained from C2H6/C3H6/C2H4 mixtures through a single adsorption/desorption cycle.

In the present study, the volatile composition of Ulva rigida (U. rigida) was elucidated by two different methods. As a result of the identification process of volatile components using the GC/MS‐FID instrument, 31 compounds were identified by hydro‐distillation (HD) method, and 15 compounds were identified by solid‐phase microextraction (SPME) method, elucidating the structure of 99.86% and 92.65%, respectively. The most abundant compounds in the essential oil of U. rigida were n‐hexadecanoic acid and pentadecanal, while the most abundant compound according to the SPME analysis was heptadecyne, a hydrocarbon compound. In the next step, hexane, dichloromethane, chloroform and methanol solvent extracts of U. rigida were prepared and the antimicrobial activities of the extracts and the essential oil obtained by hydro‐distillation as well as the scolicidal activities of the solvent extracts were determined. The results of the antimicrobial activity test of the essential oil showed a high level of activity against Bacillus cereus ATCC 10876 and MRSA. The highest activity was found on the microorganism of Pseudomonas aeruginosa ATCC 9027 in chloroform and methanol extracts of U. rigida. The values of lethal concentration doses (LD50, LD75 and LD90) were calculated using probit analysis.
