Removal of carbon dioxide using zeolitic imidazolate frameworks: Adsorption and conversion via catalysis

Research Abstract

Carbon dioxide (CO2) is one of the culprit causes of global climatic changes. Furthermore, the efficient separation of CO2 from other gaseous mixtures using zeolitic imidazolate framework (ZIF)-based materials is vital for several processes such as flue gas separation, gas sweetening, and natural gas processing. ZIF-based materials are emerging adsorbents and catalysts for CO2 gas removal via adsorption and conversion into valuable chemicals. ZIF-based adsorbents with high-adsorption/conversion efficiencies and tunable properties can be achieved by judicious synthesis and fabrication methods. We reviewed ZIF-based materials for CO2 removal via adsorption and catalysis (e.g., cycloaddition, carboxylation, hydrogenation, N-formylation, electrocatalysis, and photocatalysis). In addition, recent development methods such as membrane technologies and ways to improve the gas separation performance of ZIF membranes were highlighted. The prospective point of view to promote industrial applications and commercialization of ZIF-based materials was briefly discussed. Once challenges such as low performance and reproducibility for ZIF-based materials are solved, scalability and cost-effectiveness should not become issues.

Thiol, volatile and semi-volatile compounds

Research Abstract

Pomegranate trees are tropical and subtropical shrubs with nutritional benefits and pharmaceutical and therapeutic uses. Antioxidative systems protect the structure and function of cellular membranes. This study demonstrated the connection between oxidative stress generated by excess nanoparticles ZnO (ZnO-NPs) accumulation in pomegranate calli and the involvement of thiol groups and volatile and semi-volatile compounds in alleviating this stress. The effect of the non-enzymatic antioxidant system was studied using callus treated with three levels of ZnO-NPs or bulk particles (ZnO-BPs). With rising ZnO levels in the media, callus growth was gradually decreased by ZnO in both forms (NPs and BPs). Malondialdehyde (MDA) measurements revealed that different concentrations of both forms promoted lipid peroxidation. The supply of both forms had a considerable stimulatory influence on the cysteine (Cys

Some soft sets in soft ideal topological spaces

Research Abstract

In this paper, two types of soft sets in soft ideal topological spaces
are introduced and some of their properties are discussed. The concept
of soft condense ideals is characterized by these collections of sets.
Also, some properties of soft extremally disconnected spaces are investigated.
Furthermore, decompositions of some types of soft continuous
mappings are given and some equivalent conditions concerning this
topic are established here.
