The order of degradation to the kinetic data are as follows: OA-PbS(150) > OA-PbS(190) >OA-PbS(230) > ODA-PbS(150) > ODA-PbS(190) > ODA-PbS(230) which is in agreement with the degradation efficiency bar chart shown in Fig 6.
The redox process can be written as follows: Oxidation: PbS →Pb2+ +S+2e- Reduction: PbS+ 2e- →Pb+ S2- Fig. 7 Cylcic voltamogram of OA-PbS and ODA-PbS nanoparticles at increasing scan rates Fig. 8 Randles-Sevcik plots of OA-PbS and ODA-PbS nanoparticles Randles-Sevcik equation Ip,a=0.4463nFACnFvDRT12 was used to investigate the electrochemical properties of the PbS nanoparticles [37] based on its reversible process.

Motion and/or torque transmissions, speed reduction, change in the direction of rotation etc. are the major tasks done by these gears [1, 2].
· Final step in this phase is transferring the prepared part program to the WEDM machine through data exchange cable or USB drive.

Recently, the attention has been focused on the high energy density techniques of welding, like LBW[18] & EBW [19], because, in comparison with other techniques, they allow to get much narrower seams with enhanced penetration depth and involve lower heat input, with consequent reduction of MZ, HAZ and residual stresses [20-23].
EBSD data were produced by using an acceleration voltage of 30 kV to minimize the disturbing effects from the surface defects produced during specimen preparation.

Signal-to-noise ratio A signal-to-noise (S/N ) ratio is then calculated from the experimental data.
When compared to non-cryogenic treatment, cryogenic treatment resulted in a 29% to 54% improvement in MRR and a 0.7 to 4% reduction in surface roughness [20].

Addition of Ni powder coupled with increase in solidification rate yielded size reduction in aluminum alloy structure.

Via analyzing on absorption spectral data [7], Ruiz et al. got the relationship between bandgap Eg and Ge percent content (x) in Si1-xGex and present as following formula, , (5) Furthermore, the mobilities of electrons and holes μn, μp and the state densities of conduction band and valence one Nc, Nv were found to change with x, which can be expressed as [7, 8], , (6) , (7) , (8) where mn and mp are the effective mass of electron and hole respectively, h is the Planck constant, p is the total scattered probability of SiGe alloy, pi is the scattered probability of Si, ΔE is the bandgap difference between Ge and Si, N is the cell numbers per unit volume, m* is the effective quality of state density, T is the absolute temperature, mo is free electron quality.
As represent in Fig.6, FF also increases with increasing d due to material resistance reduction, further the h rises according to the expression (9d).

The variations in the experimental conditions like moisture content, temperature, data analysis bring out the changes in the proton conductivity of PEM.
The hydrolytic stability is normally assessed by measuring the progressions in mechanical properties, weight reduction, IEC, and proton conductivity.

The research by Mohan is demonstrated that combining peptides would drive to achieved a broad-spectrum antimicrobial activity, increased microbicidal activity in terms of fold reduction of bacteria, lower MIC of the cocktail AMPs, and much more rapid time-kill kinetics.
The data on Table 4 showed the decrease in the inhibition zone diameter with the increase in the chitosan concentration.

The software of the equipment has a data base of reference files from the Joint Committee of Power Diffraction Standards (JCPDS).
If the acid strength is high the selectivity of the reaction shifts to the catalytic cracking of the molecules with the possibility of polymerization of the olefins, producing coke which deactivates the catalytic active sites, provoking a gradual reduction in the conversion.

., in general, titanium and its alloys are the most susceptible to acid treatment, displaying a reduction in surface oxide thickness [7].
