Caption: Figure 6: (a) Color map of the XRD intensity evolution for the PdCu 3 : 1 nanoparticle mixture on the Si[O.sub.2]/Si substrate isothermally annealed at 450[degrees]C in a forming gas atmosphere showing the formation of the ordered B2 phase and another alloyed phase (see also [7]).
5 shows surface morphologies of the 309 samples oxidized isothermally with and without coating at 650[degrees]C and 750[degrees]C for 100 hrs, when the sample is oxidized in two different temperatures.
(2) Gillham and co-workers investigated the interplay between cure temperature and extent of cure to develop time-temperature-transformation (TTT) diagrams for isothermally cured epoxy-amine systems that can describe many types and classes or conditions for thermosetting polymers (Figure 11).
The developed model was adequate to model and simulate a methanol steam reforming reactor operating isothermally. The use of MatLab and its solver ODE23TB was found to be an appropriate strategy for solving the model.
Investigations made by [11,16] infinitely wide rough slider bearings isothermally for exponential, hyperbolic, and secant film shapes using couple stress fluids.
The applied potential was 2 V and all the measurements were taken isothermally, with a tolerance of 1% in temperature.
Ding and Liu [53] observed the spherulites morphologies of P(3HB) crystallized isothermally from thin melt film with different crystallization temperatures.
Nonfunctional lubricant named as PFPE Z, functional lubricants such as PFPE Zdol and PFPE Ztetraol, and different types of multidented functional lubricants such as ARJ-DS, ARJ-DD, and OHJ-DS are heated on a DLC substrate from nondimensional temperature [T.sup.*] = 1 to [T.sup.*] = 10 isothermally. This nondimensional temperature can be converted using the parameters obtained by Li et al.
The reaction was carried out isothermally at 25[degrees]C and samples of the reaction mixture were analyzed at different time intervals for a total reaction time of one hour.
Among their topics are conditions on the interface between fluids and on solid walls, models in convection of an isothermally incompressible fluid, invariant submodels of microconvection equations, small perturbations and stability of plane layers in the microconvection model, and the numerical simulation of convective flows under micrograviy conditions.
At this temperature, the samples were held 120 min isothermally to achieve complete combustion.
Samples were isothermally aged at the equivalent of 0, 2, 7 and 14 years service life.
