Biopolymers have been used in food packaging in recent years due to high pollution rates and decreased biodegradation of synthetic polymers. Chitosan (CH) and Sodium alginate (SA) are both biodegradable biopolymers with excellent film forming capability. TiO2 nanoparticles have high mechanical strength, degradation ability and antimicrobial properties, which are beneficial in food packaging. The aim of the current work is to develop the biodegradable multifunctional nanocomposite film for fruit (i.e., Pear) packaging applications. Bionanocomposite film was prepared by solvent casting method using CH-SA and various concentrations of TiO2. The multifunctional properties such as UV barrier, thermal, water retention, mechanical, chemical, …

The human heart is an exceptionally complex muscular organ that is vital for survival. Electrical impulses signal activation of mechanical contractions, pumping blood through the entire body and allowing for oxygen-exchange to occur. Unfortunately, certain disease states or traumatic injuries such as myocardial infarctions hamper the heart’s efficiency and function by damaging its structure. Ideal treatment would allow for the replacement or regeneration of the damaged tissue with cells and material harvested from the patient, thus avoiding the potential for immune rejection. Engineered cardiac tissues fabricated from human induced pluripotent stem cells have shown great promise for restoring function in …
