Tailored Dual Responsive Hybrid Gelatin Methacryloyl/Poly[2‐(Dimethylamino)Ethyl Methacrylate] Hydrogels for Efficient Ibuprofen Release in Topical Applications

Journal of Applied Polymer Science, EarlyView.
GelMA/DMAEMA hybrid hydrogels for release of ibuprofen. ABSTRACT In this study, biocompatible hydrogels intended for topical delivery of ibuprofen were synthesized from gelatin methacryloyl (GelMA) and 2‐(dimethylamino)ethyl methacrylate (DMAEMA) by varying their proportions. The impact of different GelMA and DMAEMA ratios was comprehensively evaluated

Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

X-Ray Spectrometry, EarlyView.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.
