Chitosan/Gelatin Hydrogels With Hydroxyapatite/Silver Nanoparticles: A Dual Antimicrobial and Biocompatible Platform for Bone Regeneration

Journal of Applied Polymer Science, EarlyView.
Chitosan/gelatin hydrogels containing hydroxyapatite or hydroxyapatite/silver nanoparticles were developed and evaluated for bone tissue engineering applications, demonstrating biocompatibility and antimicrobial activity. ABSTRACT Bone tissue engineering demands multifunctional biomaterials capable of promoting regeneration while preventing local ...

Quantification of Sulfonated Polyacrylamides by SEC‐UV in Produced Water: Validation and Oilfield Case Study

Journal of Applied Polymer Science, EarlyView.
Size exclusion chromatography with UV–vis detection, combined with ultrasonication pretreatment, enables sensitive detection and quantification of back‐produced polymer at very low concentrations in produced water. This approach supports reliable polymer monitoring and offers a practical route to improve surveillance of polymer flooding performance ...

Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices

Advanced Physics Research, EarlyView.
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
