ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(6)

Published: Feb. 1, 2025

Abstract The global shortage of fresh water is a critical issue, especially in regions with limited rainfall. Developing reliable and wastewater treatment technologies urgent. Among the available methods, adsorption stands out as highly effective, straightforward, cost‐efficient approach. It avoids use additional chemicals reduces risk contaminating source undesirable by‐products. Chitosan (CS)‐based hydrogels have gained attention for their excellent capacities pollutants water. These materials are also known bioavailability, biocompatibility, biodegradability, cost‐effectiveness, environmental friendliness, making them promising candidates treatment. This comprehensive review explores recent advancements CS‐based various applications, including pollutant removal, oil‐water separation, seawater desalination, atmospheric condensation. highlights benefits this material treatment, providing broader understanding potential research community. focuses on synthesis modification techniques these hydrogels, such cross‐linking, grafting, ion imprinting, which significantly enhance performance mechanical stability. Additionally, challenges faced by practical applications discussed, along solutions. paper concludes forecasting future directions field, offering valuable insights researchers. Overall, provides overview current state art into effective utilization emphasizing to address pollution challenges.

Application of Gelatin-Based Composites in Bone Tissue Engineering

Heliyon, Journal Year: 2024, Volume and Issue: 10(16), P. e36258 - e36258

Published: Aug. 1, 2024

Natural bone tissue has the certain function of self-regeneration and repair, but it is difficult to repair large damage. Recently, although autologous grafting "gold standard" for improving high cost, few donor sources. Besides, allogeneic causes greater immune reactions, which hardly meet clinical needs. The engineering (BTE) been developed promote repair. Gelatin, due its biocompatibility, receives a great deal attention in BTE research field. However, disadvantages natural gelatin are poor mechanical properties single structural property. With development BTE, often used combination with range natural, synthetic polymers, inorganic materials achieve synergistic effects complex physiological process review delves into fundamental structure unique gelatin, as well excellent necessary scaffold materials. Then this explores application modified three-dimensional (3D) scaffolds various structures including 3D fiber scaffolds, hydrogels, nanoparticles. In addition, focuses on efficacy composite consisting or polymeric materials, bioactive ceramics metallic/non-metallic defects. these gelatin-based provides new ideas design good biosafety.

Superabsorbent Hydrogels in the Agriculture and Reclamation of Degraded Areas

Sustainability, Journal Year: 2024, Volume and Issue: 16(7), P. 2945 - 2945

Published: April 2, 2024

Superabsorbent materials (SAPs) are crosslinked polymer networks composed of ionic and non-ionic monomers. SAPs can absorb retain water solutions up to several hundred times their own weight. As a result swelling, they form gel that is insoluble in water, considered safe decomposes over time. This review focuses on the synthesis, degradation chemical composition SAP materials, with particular emphasis substances soluble migrate into environment. Numerous applications natural synthetic hydrogels agriculture reclamation degraded areas preventing erosion, retention reducing leaching colloidal soil components plant protection products, fertilisers mineral salts surface waters have been described. The influence microbial activity soils New trends search for environmentally friendly made modified biopolymers waste presented, which not only increase yields, but also ensure sustainable agro-environmental development.
