Design and analysis of experiments in silica filled natural rubber compounds—effect of castor oil

Kinetics of the solvent-free hydrogenation of 2-methyl-3-butyn-2-ol over a structured Pd-based catalyst

“…(12) ( Table 2) was simplified for initial conditions. In this case, it can be shrunk into a simple power rate law expression: (20) where…”

“…It is worth noting that in order to ease the calculations and generalize the methods in DOE, the variables are normalized so as to work with variables centred in zero and varying in the interval [À1, 1].

“…The most important feature of DOE is that the results obtained are backed by a solid statistical background [18]. The application of DOE to obtain kinetic data is not recent although it has not been hitherto widely used [19][20][21]. ) [22] were used as a structured support.…”

Cure kinetics of ethylene acrylate rubber/clay nanocomposites

“…The assumption of the first order kinetics (n = 1) of curing reaction can thus lead the following simple relationship by combining Eqs. (1), (2) and (5), and integrating the a with respect to t [12][13][14].…”

Property Optimisation of EPDM Rubber Composites Using Mathematical and Statistical Strategies

“…e modelling of a given property using the design of mixture experiments is becoming common practice [9][10][11][12][13][14][15][16][17] and was proven, in all cases reported, to lead to greater e ciency and con dence in the results obtained, and to be less demanding in time and both material and human resources.…”
