Porosimetry of zeolitic imidazolate frameworks using positron annihilation lifetime spectroscopy

J. Mor et al.

Summary: Due to its crystalline morphology, Zeolitic Imidazolate Frameworks (ZIFs) have well designed pore architecture, high surface area, pore volume, and well defined pore network, making them great candidates for gas separation, gas storage, catalysis, and sensors. However, traditional gas adsorption techniques are insufficient for studying the complete pore architecture of ZIFs. Recently, positron annihilation lifetime spectroscopy (PALS) has been identified as a powerful technique for investigating the pore architecture of various ZIFs.

Novel Carbazole-Based Porous Organic Polymer for Efficient Iodine Capture and Rhodamine B Adsorption

Hongyu Wang et al.

Summary: A new porous organic polymer (CTF-CAR) was synthesized through catalyst-free Schiff-base polymerization, using carbazole as the electron-rich center unit and thiophenes as the auxiliary group. The structure, thermal stability, morphology, and other properties of CTF-CAR were analyzed, and its high uptake capacities for iodine vapor and rhodamine B were observed. The recyclability test confirmed its good reusability. This low-cost and catalyst-free synthetic porous organic polymer shows great potential for the treatment of polluted water and iodine capture.

Porous organic materials for iodine adsorption

Jintu Francis Kurisingal et al.

Summary: The nuclear industry will continue to develop and produce energy in the foreseeable future, but the disposal of waste radionuclides, particularly radioactive iodine, presents unique challenges due to their volatility and long half-life. Although various adsorbents have been explored, there is still interest in developing novel adsorbents. This review discusses the performance of different porous organic materials for iodine uptake, their synthesis methods, adsorption capacity, reusability, as well as the challenges and prospects in utilizing them for iodine capture.

Flexibility of Mixed Ligand Zeolitic Imidazolate Frameworks (ZIF-7-8) under CO2 Pressure: An Investigation Using Positron Annihilation Lifetime Spectroscopy

Jaideep Mor et al.

Summary: Fine tuning the pore architecture and flexibility of zeolitic imidazolate frameworks (ZIFs) is crucial for their applications in gas separation. This study investigates the tuning of pore architecture and flexibility of ZIF-7-8 frameworks with different benzimidazole (bIm) contents using positron annihilation lifetime spectroscopy (PALS) measurements under CO2 pressure. The results show that the frameworks' aperture and cavity open up with increasing bIm content but decrease at higher content. Flexibility, measured using PALS under CO2 pressure, initially decreases and then increases. The study reveals that frameworks with larger apertures are less flexible due to the open configurations of ligands in the lattice, while frameworks with smaller apertures exhibit higher flexibility due to ligand twisting under CO2 pressure. The pore-opening phenomenon induced by lattice flexibility under CO2 pressure is reversible for ZIF-7-8.

Timothee Stassin et al.

Summary: Thin films of crystalline and porous metal-organic frameworks (MOFs) have great potential in various applications, but characterizing their pore size, volume, and surface area can be challenging. Positron annihilation lifetime spectroscopy (PALS) is introduced as a powerful method to obtain pore size information in MOF films, complementing existing physisorption-based techniques.

A comprehensive review on radioactive waste cycle from generation to disposal

Sharif Abu Darda et al.

Summary: Radioactive wastes are hazardous byproducts of nuclear technology and industrial processes that need to be governed and regulated by government authorities. Different management strategies are implemented based on the type and intensity of radioactive waste, with most waste going through volume reduction, waste immunization, and shielding before being disposed of in long term geological repositories. Highly radioactive spent fuel and reprocessing wastes are temporarily stored until a long-term disposal solution is found.

Summary: In this study, three types of zeolite imidazole frameworks were synthesized and analyzed for their pore structures and CO2 adsorption capacities. The results indicate that at atmospheric pressure, CO2 is effectively captured by micropores, while at extremely low pressures, CO2 is mainly enriched around ultramicropores.
