Introduction: Rapid population growth and industrialization have increased chemical pollutants. Some studies show that employee exposure to formaldehyde in industrial places, hospitals, and laboratory settings is more than the allowed limits. Therefore, it is necessary to implement a proper control system to reduce this exposure. This study aimed to synthesize Ag3PO4/TiO2 nanocomposite, determi...

Barium Oxide(BaO) nanoparticles were synthesized by simple co-precipitation method and were investigated by the catalytic activity of synthesized barium oxide nanopaticles was enumerated by epoxidation of styrene. The reaction was carried out and the product was obtained at higher efficiency. Particularly, the photocatalytic efficiency was estimated by degradation of Rhodamine-B (RhB) dye using...

PURPOSE To design patterned, transparent silk films with fast degradation rates for the purpose of tissue engineering corneal stroma. METHODS β-sheet (crystalline) content of silk films was decreased significantly by using a short water annealing time. Additionally, a protocol combining short water annealing time with enzymatic pretreatment of silk films with protease XIV was developed. RES...

A key attribute missing from many current biomaterials is the ability to independently tune multiple biomaterial properties without simultaneously affecting other material parameters. Because cells are well known to respond to changes in the initial elastic modulus, degradation rate, and cell adhesivity of a biomaterial, it is critical to develop synthetic design strategies that allow decoupled...

Poly(glycerol sebacate) (PGS), a tough elastomer, has been proposed for tissue engineering applications due to its desired mechanical properties, biocompatibility and controlled degradation. Despite interesting physical and chemical properties, PGS shows limited water uptake capacity (∼2%), thus constraining its utility for soft tissue engineering. Therefore, a modification of PGS that would mi...

Collagen-based scaffolds can be used to mimic the extracellular matrix (ECM) of soft tissues and provide support during tissue regeneration. To better match the native ECM composition and mechanical properties as well as tailor the degradation resistance and available cell binding motifs, other proteins or different collagen types may be added. The present study has explored the use of componen...

Black phosphorus (BP) possesses several extraordinary physical properties, which include in-plane anisotropy, thickness dependent direct bandgap and high carrier mobility. These physical properties make BP highly desirable from the point of view of fundamental science and modern optoelectronics applications. The excitement about this material has always been accompanied by unreserved skepticism...
