Impact of Formulation Ingredient Compatibility on Encapsulation of Hydrophobic Substances in Polymeric Nanocarriers Prepared by Nanoprecipitation

Macromolecular Materials and Engineering, EarlyView.
Encapsulation of hydrophobic drugs in poly(lactic‐co‐glycolic) acid (PLGA) nanoparticles strongly depends on solvent and polymer compatibility. By linking Hansen solubility parameters with atomic force microscopy (AFM), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC) analyses, the work reveals predictive markers of ...

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character

Macromolecular Rapid Communications, EarlyView.
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Temperature‐Dependent Chain Structures during Solution‐Grown Crystallization via Atomic Force Microscopy

Macromolecular Rapid Communications, EarlyView.
AFM‐based single‐molecule force spectroscopy was employed to investigate temperature‐dependent single‐chain folding structures of semi‐crystalline PEO. Force–volume measurements enabled correlation of force–extension behavior with local crystal morphology. Results reveal temperature‐dependent aggregation structures, with intermediate structures favored

Toward Dynamic Liquid Cell Scaffold: Photoreversible Ion Gels Exhibiting Light‐Induced Sol‐Gel Transitions

Macromolecular Rapid Communications, EarlyView.
Light‐programmable, non‐cytotoxic ion gels based on ABC triblock copolymers undergo photoreversible sol‐gel transitions, crossing the rheological boundary (tan δ ∼ 1). UV–vis light irradiation modulates the lifetime of reversible junctions, switching the scaffold between liquid‐like and solid (gel)‐like states.

Advancing Severe Plastic Deformation for Tubular Samples: Systematic Review and Machine Learning Optimization

MetalMat, EarlyView.
This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent
