Temperature Sensitive Pluronic F127‐Based Gels Incorporating Natural Therapeutic Agents
Macromolecular Materials and Engineering, Volume 310, Issue 4, April 2025.Pluronic F127‐based injectable gels are designed for therapeutic applications. The curcumin encapsulation efficiency and stability of formulations are investigated in aqueous environment and in acetic acid solutions. The viscoelasticity of gels, correlated with the network structure, is influenced by xanthan gum or acetic acid addition.

Nuclear Magnetic Resonance Diffusometry of Linear and Branched Wormlike Micelles [PDF]
arXiv, 2021 Diffusion studies using nuclear magnetic resonance (NMR) spectroscopy were conducted on two model surfactant solutions of cetyltrimethylammonium bromide/sodium salicylate (CTAB/NaSal) and cetylpyridinium chloride/sodium salicylate (CPCl/NaSal). By increasing the salt-to-surfactant concentration ratio, these systems display two peaks in the zero-shear ...

In Situ Gels for Nasal Delivery: Formulation, Characterization and Applications
Macromolecular Materials and Engineering, EarlyView.Drug delivery through the nasal route offers many advantages, but is hampered by a number of challenges, such as the short drug retention time caused by mucociliary clearance. In situ forming gels, which undergo a sol‐to‐gel transition with specific triggers at the site of action, present real opportunities in this field.

Macromolecular Materials and Engineering, EarlyView.The poloxamer Pluronic‐F‐127‐based hydrogels are improved by the implementation of polysaccharides with different concentration ranges and structural organizations. The interactions between the polysaccharide structures and the poloxamer micellar aggregation confer the system better rheological properties and longer drug release times explained by ...

Free Radical Entry in Emulsion Polymerization: A Comprehensive Theory
Macromolecular Reaction Engineering, EarlyView.Contrary to previous theories on free radical entry, most of the initiator‐derived radicals can enter the particles. Their contribution to the total entry rate can vary depending on a balance between thermodynamic and kinetic factors where electrostatic repulsion plays an important role which accentuates the diffusive control of the entry process ...

Interaction of Caffeic Acid with SDS Micellar Aggregates
Molecules, 2019 Micellar systems consisting of a surfactant and an additive such as an organic salt or an acid usually self-organize as a series of worm-like micelles that ultimately form a micellar network.
