AI Article Synopsis
- A new self-assembled metal-organic gel was created using ferric nitrate and bis(3-pyridyl)terephthalate, forming a stable three-dimensional network of nanofibers.
- The gel's formation was highly selective to Fe(iii), and its properties were significantly influenced by the Fe3+ to ligand ratio.
- The gel demonstrated responsiveness to multiple stimuli and heat resistance, allowing it to serve as a template for creating core/shell polymer composite nanowires, which showed improved mechanical strength after processing.
Article Abstract
In this study, a novel self-assembled metal-organic gel was synthesized from ferric nitrate and a di-topic ligand, bis(3-pyridyl)terephthalate. The gel consisted of a three dimensional network of uniform nanofibers. The gelation exhibited high selectivity to Fe(iii) based on metal-ligand coordination. The molar ratio of Fe3+ to ligand had a large influence on the assembly process and the morphology of the gel. The metallogel displayed multi-stimuli responsiveness and excellent heat resistance, thus was further applied as a thermo-stable template for the polymerization of N,N'-methylene bisacrylamide to produce the core/shell polymer composite nanowires. Subsequently, the polymer nanotubes were obtained after ammonia post-treatment, comfirming the feasibility of the template synthesis strategy. According to the rheological measurements, the gel-like products of the composite nanowires exhibited better mechanical strength compared to the gel template.

This work aimed to elucidate the deterioration mechanisms of shrimp surimi gels during refrigerated storage, and the regulatory mechanisms of epigallocatechin-3-gallate loaded cyclodextrin-based metal-organic framework (EGCG@CD-MOF) as a model antioxidant. Labele-free proteomics provided a quantitative analysis of the differential proteomic signatures of degraded proteins. Structural proteins, like myosin, paramyosin, titin, laminin, and α-actinin, along with calcium regulatory proteins, like calcineurin and sarcoplasmic calcium-binding protein were found to be highly susceptible to oxidative degradation during refrigeration.

Background: The metal organic cages (MOCs) are an emerging type of porous material that has attracted considerable research interest due to their unique properties, including good stability and well-defined intrinsic cavities. The chiral MOCs with porous structures have broad application prospects in enantiomeric recognition and separation. However, there are almost no relevant reports on chiral MOCs as chiral stationary phases (CSPs) for enantioseparation by high-performance liquid chromatography (HPLC).

Trauma healing is the process of healing after the body has been subjected to an external force and the skin and other tissues have become dissected or defective, showing the synergistic effect of various processes. Therefore, the investigation of innovative wound dressings has significant research and clinical implications. In this study, we constructed a zinc based metal-organic framework (MOF) and loaded with antimicrobial peptide LL37 to prepare LL37@ZPF-2 (ZPF = zeolite pyrimidine backbone), which was subsequently integrated with Poloxamer 407 to fabricate LL37@ZPF-2 thermosensitive hydrogel.

This study describes the preparation of novel hybrid aerogels derived from gelatin (Gel), incorporating Br-functionalized zirconium-based metal-organic framework (UiO-66-Br; MOF) as modifying agent to effectively eliminate phosphate and fluoride ions from aqueous environments. The adsorption performance of MOF decorated Gel (Gel-xMOF) hybrid aerogels was investigated under different conditions, including agitation time, adsorbent dosage, solution pH, initial phosphate and fluoride concentrations, coexisting ions, and temperature. The functional groups of the gelatin network, coupled with UiO-66-Br, enhanced the adsorption performance of phosphate and fluoride ions from aqueous solutions.

Polymer electrolytes incorporated with fillers possess immense potential for constructing the fast and selective Li conduction. However, the inhomogeneous distribution of the fillers usually deteriorates the microdomain consistency of the electrolytes, resulting in uneven Li flux, and unstable electrode-electrolyte interfaces. Herein, we formulate a solution-process chemistry to in situ construct gel polymer electrolytes (GPEs) with well-dispersed metal-organic frameworks (MOFs), leading to a uniform microdomain structure.
