The generation of heat‐stable salts (HSSs) in alkanolamine solutions for CO2 capture processes, which is adapted for power plant technologies, exists irrespective of the class of amine solution used for the capture process. Their presence do not only trigger decrements in the CO2 absorption capacities of the solvents and contribute to further alkanolamine degradation, but also result in foaming and loss of solvents, which impacts system economics and threatens the environment. HSSs also promote the corrosiveness of the metallic structures of capture systems by lowering the pH and increasing the conductivity of the absorbent solutions. Overall, these effects substantially subvert the reliability and integrity of CO2 capture units. This survey affords sufficient background on the existence of HSSs by unraveling the flow process in a typical alkanolamine‐based CO2 capture unit with respect to their formation points and potential threats. Furthermore, the major HSSs removal and alkanolamine reclamation methodologies (electrodialysis, distillation, ion exchange, electromagnetic separation, and solvent extraction) were comprehensively explored. We believe that this review paper will benefit researchers across disciplines as we continue to explore new and complex solvent formulations to minimize the cost of CO2 capture while maximizing efficiency. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

Plastics pollution has been a global concern. Huge quantities of polyethylene (PE), the most abundant and refractory plastic in the world, have been accumulating in the environment causing serious ecological problems. However, the paucity of microorganisms and enzymes that efficiently degrading PE seriously impedes the development of bio-products to eliminate this environmental pollution. Here, by screening hundreds of plastic waste-associated samples, we isolated a fungus (named Alternaria sp. FB1) that possessing a prominent capability of colonizing, degrading and utilizing PE. Strikingly, the molecular weight of PE film decreased 95% after the fungal treatment. Using GC-MS, we further clarified that a four-carbon product (named Diglycolamine) accounted for 93.28% of all degradation products after the treatment by strain FB1. We defined potential enzymes that involved in the degradation of PE through a transcriptomic method. The degradation capabilities of two representative enzymes including a laccase and a peroxidase were verified. Lastly, a complete biodegradation process of PE is proposed. Our study provides a compelling candidate for further investigation of degradation mechanisms and development of biodegradation products of PE.

Applying biological macromolecule like curcumin (CUC) has gained considerable attention for the anti-inflammatory, antioxidant, antimicrobial and antitumor properties. Therefore, this study was carried out to characterize carboxymethylcellulose/ calcium alginate (CMC/CA) scaffold loaded with CUC in skin tissue engineering. To observe the structural, mechanical, degradability, biological and antibacterial effect of CUC, it was loaded in a cellulose-based electrospinning scaffold of sodium CMC (SCMC) with CA. The addition of CUC increased the fiber diameter to 504 ± 83, and 522 ± 25 nm in 3% and 5% of CUC concentrations, respectively. The elasticity of the scaffold was enhanced, while the scaffold strength was decreased slightly. The inhibitory zone in the scaffold containing CUC denoted to its antibacterial properties. In addition, the cell viability, proliferation and attachment to the electrospun scaffolds were increased. Utilization of CUC-loaded materials can play an important role in anti-bacterial performance of the scaffold. Although mechanical properties of SCMC may slightly decreased during the loading process, but the morphological, chemical, and biological properties were improved. It seems that applying electrospinning technique and CUC incorporation in fabricated scaffolds can be a promising choice in skin tissue engineering when antibacterial properties are also targeted in conjunction with the tensile strength.
