Intervertebral disc degeneration (IDD) is considered an important pathological basis for spinal degenerative diseases. Tissue engineering is a powerful therapeutic strategy that can effectively restore the normal biological properties of disc units. In t
Polyvinyl alcohol was procured from Fisher scientific, India. For the preparation of magnesium ferrite NPs, AR grade magnesium nitrate hexahydrate, Mg(NO3)2·6H2O, iron nitrate hexahydrate, Fe(NO3)2·6H2O, and glycine (obtained from Merck, India) were used. The purity of the chemicals used ...
Cohen and Turnbull formula for the translational self-diffusion coefficient was tested in the free-volume cast, which itself was correlated against the isothermal compressibility, which can explain the phenomenon of transport properties in liquids, D∝exp-γ/Vf/V∗. The fractional Stokes-Einstein ...
of insoluble polymer. A photocross-linkable polymer such as a derivative of polyvinyl alcohol is used for this purpose. In this method, the enzyme is surrounded by the polymer so that the diffusion of the substrate sometimes can be the determining factor in the rate of reaction. Fabrication ...
labeled as negative, which makes the signal of every partition Boolean. Therefore, by calculating the number of compartments generated and the positive rate after the reaction, the original copies of the tested samples can be reconciled through the Poisson distribution formula without a standard curve...
1. Vinylamine homopolymer of 3.6 to 9x106 average molecular weight consisting essentially of units of the formula: where R1 is hydrogen or a C2-C4 alkyl group. 2. The vinylamine homopolymer of claim 1, characterized in that its average molecular weight is 7x106. 3. The vinylamine homopo...
The Einstein-Stokes Equation is a formula for calculation of Brownian Diffusivity, where diffusivity varies directly with absolute temperature and varies inversely with both viscosity and molecular radius: kT D = --- 6πrµ D = Brownian Diffusivity k = Boltzmann's constant T = absolute...
The evolution of FB diffusion flux calculated from the formula is used to characterize the solidification rates of PAMS/FB droplets (FB mass per unit time through unit area). In order to simplify the calculation, the concentration process of PAMS solution with no volume effect is assumed, as ...
the glass transition of polymers. These results indicate that graphene can promote the movement of polymer segments and reduce the glass transition temperature of the polymer. Zhang et al. [21] used MD to study the swelling performance of polyvinyl alcohol (PVA) in water/ethanol solution, and ...
