3 days ago · The relationship between the activation energy (Ea) and the conversion rate (α) calculated based on the Flynn–Wall–Ozawa equation and the Starink equation is shown in Fig. S4d. The calculation results are shown in Table S4 , the average activation energy calculated by Flynn–Wall–Ozawa equation, Starink equation and Friedman equation are 243.33 kJ/mol, 241.69 kJ/mol and 227.81 kJ/mol ...
4 days ago · Rate equation. In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only ...
1 day ago · The diffusion-mediated localized F-actin production enabled us to write an ordinary differential equation (Eq. 1 ) where G-actin locally gets converted into F-actin in an Arp2/3 dependent manner.
2 days ago · Maxwell's equations are partial differential equations that relate the electric and magnetic fields to each other and to the electric charges and currents. Often, the charges and currents are themselves dependent on the electric and magnetic fields via the Lorentz force equation and the constitutive relations.
3 days ago · If Fmax 1 is reached during pretreatment, equation 2 can be simplified to equation 4: (4) % D i s s ∞ 0 = F m a x 1 · + ((F m a x 2 − F m a x 1 ·) · (1 − e − (t − g t α 2) β 2)) If the precipitation or dissolution after gastric pretreatment is immediate, the second exponential will be 0, so Fmax 2 will become the constant that allows the equation to give the same value ...
4 days ago · Parabolic equations are often called diffusion equations because they describe the diffusion and convection of some substance (such as heat). The dependent variable usually represents the density of the substance.
