Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Adsorption Properties and Wettability of Ethoxy- and Propoxy- Derivatives of 2-Ethylhexanol as Sterically Specific Surfactant Structures

Molecules
2-ethylhexanol, an oxo alcohol competitively priced on the global market, has not been explored intensively as a raw material for surfactants, due to its weak hydrophobic character.

Predicting air‐entraining in cement paste from the molecular attributes of nonionic surfactants with a multilayer method

Journal of the American Ceramic Society, EarlyView.
Abstract The novelty of this study is to present a multilayer framework for predicting the air‐entrained porosity of cement paste based on the molecular characteristics of nonionic surfactants. Air‐entraining agents enhance concrete durability against freeze–thaw damage; however, their development is labor‐intensive and cost‐prohibitive.

Modulating Antimicrobial Activity and Structure of the Peptide Esc(1‐21) via Site‐Specific Isopeptide Bond Formation

Journal of Peptide Science, Volume 31, Issue 9, September 2025.
The introduction of an isopeptide bond at the lysine residues in the backbone of Esc(1‐21) led to the generation of five analogs. Among these, Esc(1‐21)ε20 showed the most promising features, having antimicrobial activity comparable with those of the parent peptide, a lower cytotoxicity, and a higher stability to proteolytic degradation.

Innovative Thermosensitive Composite Materials: Merging Poloxamer PF‐127 and Polysaccharides for Enhanced Functional Properties

Macromolecular Materials and Engineering, Volume 310, Issue 7, July 2025.
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 ...

Gold Nanoparticle Adsorption and Uptake are Directed by Particle Capping Agent

Small Science, Volume 5, Issue 7, July 2025.
This study explores how ligand‐coated gold nanoparticles (NPs) interact with model membranes. Combining atomic force microscopy (AFM) and molecular dynamics (MD) simulations, it shows how coating properties affect adsorption. The AFM‐MD approach offers a predictive platform for nanoparticle design and toxicity, enabling tailored nanomedicine ...
