Moreover, the time needed to reach the sorption equilibrium doesn't seem to depend on [Cd 2+ ]o (as Xu and al.
These observations uphold the assumptions of Da Rocha et al
Two mechanisms can explain these phenomena : an ionic exchange or a heterogeneous nucleation; as suggested by Valsami-Jones and al for Cd 2+ and Pb2+ [1].

Al and Ti are also present in minor amounts.
Superalloy 718 is age-hardened by combined precipitation of fine γ'' (a meta stable intermetallic compound Ni3Nb, tetragonal centered crystal) and, of with minor contribution, of γ' (intermetallic compound Ni3(Ti,Al), simple cubic crystal) phases in an austenitic matrix γ (face centered cubic).
These particles are considered irreversible traps of hydrogen with an activation energy 1 I�CO�EL is a trademark of Inco Alloys International, Inc., Huntington, WV.

Runov et al. [8, 10,11] showed that the samples of Sm1-xSrxMnO3 compound with x = 0.25 and 0.4 at low temperature contain F clusters of size 180 – 250 Å, that are coexisting with large clusters with dimensions up to several thousand angstroms.
As it was mentioned in Introduction, in these compounds at low temperatures, the F clusters 180–250 Å in size coexisting with larger clusters with dimensions up to several thousand angstroms were observed by Runov et al. [8,10] and that can be the cause of SGV.

Aprea et al. [4] studied the influence of adopting an IHX on the coefficient of performance from a thermodynamic point of view, assuming no pressure loss.
Domanski et al. [5] showed that the benefits of application of the suction-liquid line heat exchanger depend on a combination of operating conditions and fluid properties.
Mastrullo et al. [6] presented a chart for predicting the effectiveness of IHX installation for 19 different ozone friendly fluids, and concluded that the advisability of the IHX installation can be evaluated as a function of thermodynamic properties.
Bahrami at el. [2] studied a designed internal heat exchanger for R134a automotive air conditioning system.

In 2009, Mai et al reported that the flower of Etlingera elatior contains 1.05mg of cyanidin-3-glucoside per 100g of fresh plant.
The absorption peak at 534nm may attributes to the betanin content in the leaf of the Amaranthus spp. as reported by Stintzing et al.[2004].
It can be seen that Duranta erecta and Amaranthus spp had lower current density which may be due to the less available bonds that can be occured between the dye molecules and TiO2 semiconductor surface as reported by Garcia et al., [2003] and thus less electrons transfer from the dye molecules to the TiO2.
