- Ionogels were created by mixing Aerosil A380 with varying amounts (16.3 to 79.9 mol %) of a specific ionic liquid, 1-methyl-3-octyl-imidazolium tetrafluoroborate (OMIM BF).
- Evidence of changes in the ionic liquid's behavior was observed through NMR and IR spectroscopy, indicating that the liquid was confined within the silica structure, which also affected its decomposition temperature.
- Structural analysis revealed that the ionic liquid filled different pore sizes in the Aerosil, with notable increases in size correlations in higher IL content; this suggests that altering IL concentrations can modulate the material's properties effectively.

Article Synopsis
- Small particles and molecules moving through nanopore membranes have significant implications, which necessitate the development of mathematical models to understand these processes.
- A new model using empirical equations predicts how substances move through solid-state nanopores, linking ionic current to properties like size, charge, and mobility.
- Testing the model with ceria nanoparticles showed results consistent with existing methods, highlighting its versatility for research on various porous materials and applications in filtration and electrodialysis technologies.
Purpose Of The Study: the creation of a dextran coating on cerium oxide crystals using different ratios of cerium and dextran to synthesize nanocomposites, and the selection of the best nanocomposite to develop a nanodrug that accelerates quality wound healing with a new type of antimicrobial effect.
Materials And Methods: Nanocomposites were synthesized using cerium nitrate and dextran polysaccharide (6000 Da) at four different initial ratios of Ce(NO)x6HO to dextran (by weight)-1:0.5 (Ce0.
