Polyurethane foam from oil palm fruit waste: synthesis and characterization of biopolyol and foam properties
… of this research is to produce of polyurethane (PU) foams with biopolyols from liquefied oil palm fruit waste (PW). Three parts of oil palm fruit waste (PW): oil palm mesocarp fiber (PM), oil palm shell (PS) and oil palm kernel (PK) was liquefied using liquefaction solvent with sulfuric acid as …

Collagen Scaffolds for Tissue Engineering: The Relationship between Microstructure, Fluid Dynamics, Mechanics and Scaffold Deformation
… with predictions from mathematical models and computational simulations. At low pressures, it was found that the lower collagen fraction structures, which had more open morphologies, had higher permeabilities. Alignment of the structure also enhanced permeability. The scaffolds all experienced …
