Compression elastic modulus of neutral, ionic, and amphoteric hydrogels based onN-vinylimidazole

Swelling Characterization of Nanocomposite Hydrogels of Poly (acrylamide-N-vinylimidazole)

In this study, a hydrogel composed of acrylamide (AAm) with N-vinylimidazole (NVI) as co-monomer, with a cross-linker such as N, N` Methylenebisacrylamide and potassium peroxodisulfate as an initiator solution was prepared. Poly (AAm/NVI) hydrogels were synthesized by free radical solution polymerization. Swelling experiments were performed in water at 25°C, gravimetrically. Here, it was of...

Evaluating the effect of pH on mechanical strength and cell compatibility of nanostructured collagen hydrogel by the plastic compression method

Objective(s): One of the main constraints of collagen hydrogel scaffolds for using in tissue engineering is mechanical weakness. Plastic compression (PC) is a physical method to overcome the mechanical limitation of collagen hydrogel. Materials and Methods: In this study, the effects of pH on mechanical and biological properties of PC hydrogels were investigated. Collagen hydrogels were fabrica...

Elastic Modulus of Osteoporotic Mouse Femur Based on Femoral Head Compression Test

A biomechanical test is a good evaluation method that describes the structural, functional, and pathological differences in the bones, such as osteoporosis and fracture. The tensile test, compression test, and bending test are generally performed to evaluate the elastic modulus of the bone using mice. In particular, the femoral head compression test is mainly used for verifying the osteoporosis...

Modulus of elastic pdf

The modulus of elasticity Youngs modulus E is a material property, that. From the Hooks law the modulus of elasticity is defined as the ratio of the stress to.modulus of elasticity of the cultured SC cells examined in this study, in central, non-nuclear regions, ranged between. Johnson B.all require an effective E, the Youngs modulus or elastic modulus, to quantify. Elastic moduli, such as the ...
