ZERO Tints

Here vT is the transposed matrix of stoichiometric numbers and Tint is the matrix of stoichiometric coefficients for intermediates. Elements of the latter are taken to be negative if substance is consumed in a given reaction step, positive if it is formed, and zero if substance is not involved in the reaction step. Multiplication of matrix vT (P-by-s) by matrix Tmt (s-by-/tot) gives the matrix vTrint whose size is (P-by-/tot) (s is the number of steps). 

Each specimen was single-cycle-loaded to cause a crack extension of between zero and 2 mm. The load-unload method was used, in conjunction with heat-tinting and fatiguing techniques [ ]. Crack extension (Aa) was measured at three locations across the thickness and averaged, while / calculations were based on the approximation [ ]...

The greatest attractive energy occurs at the minimum of the plot, where int = - and the separation is r = r an- The separation at which = 0, which occurs at the intersection of the L-J plot and the horizontal zero line, is denoted by ro, so the interaction energy for the molecule pair is negative for r > tq. The interaction force is Tint = -9T int/9r, which is the negative of the slope of the int versus r plot. Since a negative slope corresponds to a repulsive force, the force between the molecules is repulsive when the separation is less than rmin and attractive when it is greater. At r = r ain, the slope is zero and there is no net force due to interactions between the pair of molecules. 

Fig. 2.6 The experimental determination of the change in entropy of a sample that has a heat capacity that varies with temperature, as shown in (a), involves measuring the heat capacity over the range of temperatures of interest, then plotting C/T against T and determining the area under the curve (the tinted area shown), as shown in (b). The heat capacity of aU solids decreases toward zero as the temperatiu e is reduced.
