Carboxymethylated and Sulfated Furcellaran from and Its Immobilization on PLA Scaffolds.

This study involved the creation of highly porous PLA scaffolds through the porogen/leaching method, utilizing polyethylene glycol as a porogen with a 75% mass ratio. The outcome achieved a highly interconnected porous structure with a thickness of 25 μm. To activate the scaffold's surface and improve its hydrophilicity, radiofrequency (RF) air plasma treatment was employed.

Controlled release of enrofloxacin by vanillin-crosslinked chitosan-polyvinyl alcohol blends.

In transdermal drug delivery applications uniform drug distribution and sustained release are of great importance to decrease the side effects. In this direction in the present research, vanillin crosslinked chitosan (CS) and polyvinyl alcohol (PVA) blend based matrix-type transdermal system was prepared by casting and drying of aqueous solutions for local delivery of enrofloxacin (ENR) drug. Subsequently, the properties including the morphology, chemical structure, thermal behavior, tensile strength, crosslinking degree, weight uniformity, thickness, swelling and drug release of the CS-PVA blend films before and after crosslinking were characterized.

3D Porous TiC MXene/NiCo-MOF Composites for Enhanced Lithium Storage.

To improve Li storage capacity and the structural stability of TiC MXene-based electrode materials for lithium-ion batteries (LIBs), a facile strategy is developed to construct three-dimensional (3D) hierarchical porous TiC/bimetal-organic framework (NiCo-MOF) nanoarchitectures as anodes for high-performance LIBs. 2D TiC nanosheets are coupled with NiCo-MOF nanoflakes induced by hydrogen bonds to form 3D TiC/NiCo-MOF composite films through vacuum-assisted filtration technology. The morphology and electrochemical properties of TiC/NiCo-MOF are influenced by the mass ratio of MOF to TiC.
