A negative or cathodic peak shift (as in case of ferrocene and its other derivatives) reveals that the electrostatic mode of interaction in which negatively charged phosphate group of double helix makes electrostatic interaction with the electropositive metal atom/ion/molecular species.
The results obtained from cyclic polarization experiments revealed large hysteresis and less electropositive potentials for alloys A35 and SS316, indicating the susceptibility of pitting corrosion.
This form of passive layer could be less porous and more compact such that it could shift the corrosion-potential towards more electropositive direction while it mitigates corrosion effects in chloride-contaminated environment [34].
In this study, electronegative HA covalently bound to electropositive chitosan via EDC to formulate assembly into NPs with drug loading activity.
This was in the order [Ni.sup.2+] < [Cu.sup.2+] < [Zn.sup.2+] with [Zn.sup.2+] being the most electropositive one.
However, similar considerations can be applied for an electropositive gas such as water vapour: the molecule will act as a donor level inducing a downward band bending at the surface [28].
The portion with red color is representative of negative charge with higher electron density, while the region in blue is electropositive with lower electron density.
Under these conditions, two types of linkages confer stability on the aggregates: electronegative functional groups of the organic matter bind to the electropositive domains of the oxides, and [Al.sup.3+] ions form bridges between oxide domains (Vrdoljak and Sposito 2002; Six et al.
"So if you have a positive terminal that is energetically 'lower' (more electropositive) than the negative terminal, than the electrons will flow 'downhill' to the positive terminal.
Numerous detached electropositive amino groups in the shell covered SPION-CDDP nanoparticles were able to electrostatically adsorb electronegative TFPI-2 pDNA.
The electrochemical cell configuration thus consists of one metal (more electropositive) as anode and the other as cathode (more electronegative) connected via the junction electrolyte as indicated in Scheme 1 [24].
