Summary: This study aimed to effectively separate toluene/n-heptane mixtures by preparing a cross-linked polyvinyl alcohol (PVA) membrane and incorporating graphene oxide (GO) into mixed matrix membranes (MMMs). The PVA membrane with a molecular weight of 130,000 showed a permeation flux of 24.8 g/m2h and a separation factor of 5.5. Increasing the GO loading enhanced the total flux, with the PVA-1.5GO sample exhibiting the best performance, with a permeation flux of 30.6 g/m2h and a separation factor of 11.9, leading to a 199% increase in the pervaporation separation index (PSI) compared to pure PVA membrane.

Summary: In order to improve the synergy between plasma technology and catalyst for toluene degradation, M-BTC MOFs (M=Mn, Cu, Ce) were used as coupling agents with non-thermal plasma. The synthesized M-BTC MOFs showed excellent crystallinity, morphology, and thermal stability. The DBD-catalysis system exhibited better toluene degradation performance compared to the single DBD system. DBD coupled with Mn-BTC achieved the highest toluene degradation efficiency of 96.27%, energy efficiency of 22.32 g/kW center dot h, CO2 selectivity of 53.5%, and mineralization degree of 70.17% under SED of 766.35 J/L. Furthermore, DBD/Mn-BTC had the lowest ozone and NOx production. The mechanism of toluene degradation was analyzed using plasma emission spectra analysis, XPS spectra, and GC-MS diagram analysis.

Summary: Expanding the structural diversity of porphyrinic metal-organic frameworks (PMOFs) is crucial for developing functional materials with novel properties or improved performance. This study presents a strategy for constructing rare-earth (RE) PMOFs with unprecedented topologies through rational functionalization of porphyrinic ligands. By introducing phenyl/pyridyl groups to the meso-positions of the porphyrin core, the symmetries and connectivities of the ligands are adjusted, resulting in the successful synthesis of three new topologies of RE-PMOFs (BUT 224/-225/-226). Moreover, BUT-225(Co), which possesses both Lewis basic and acidic sites, exhibits enhanced CO2 uptake and catalytic activity for the cycloaddition of CO2 and epoxides under mild conditions. This work demonstrates the rational design and construction of RE-PMOFs with novel topologies through ligand functionalization, providing insights into tailored PMOFs for various applications.

Summary: The extinction limits and flame microstructures of CH4 versus air (N-2/O-2) counterflow diffusion flames with additional CO2 in the oxidizer stream under various pressure conditions were numerically investigated using a proposed decoupled strategy. The results showed that the extinction limits decreased with CO2 addition and extended with increased pressure. The flame microstructures changed from far away from extinction to near extinction mainly through a narrower combustion zone and thinner flame thickness, with no visible displacement of the flame front location.
