With the development and accessibility of commercial three-dimensional (3D) printers, the capability of manufacturing highly interconnected and porous 3D scaffolds holds signifi cant interest and great potential in the biomedical fi eld. Unfortunately, current table-top printing modalities are largely predicated on their more expensive commercial counterparts leveraging proven printing material...

Phase change materials (PCMs) are promising thermal energy storage due to their high specific latent heat. Conventional PCMs typically exploit the solid–liquid (s–l) transition. However, leakage and leaching common issues for PCMs, which have be addressed before usage in practical applications. In contrast, solid–solid (s–s) would naturally overcome these inherent form stability homogeneity. th...

A new polymeric construct is proposed as a starting material for liver-targeted delivery system in the present communication. The has been designed to be sensitive pH variations and potentially loaded with hydrophobic antitumoral agents. It based on one of most used copolymers field nanomedicine: PEG-PLA. latter, usually obtained by polymerization lactic acid hydroxyl-terminated polyether, asse...

Biodegradable synthetic hydrogels have emerged as promising materials for tissue engineering and drug/cell delivery applications. However, their successful implementation requires precise understanding of the degradation response in terms mechanical properties, swelling, mass loss. In this work, we develop a thermodynamically-consistent continuum framework constitutive models coupled large defo...
