“…The impedance diagram presented in Fig. 4 shows an increase in the diameter of the depressed semicircles when the increase in Sn content of the electrodeposits, this leads to an increase of corrosion resistance which has also been mentioned by Brunoro et al [26]. Consequently, the increase of R p values and decrease of capacitance values for the Cu-Sn alloys, clearly confirm the better corrosion resistance of these alloy coated samples compared to bare MS substrate.…”

“…Other important applications of SAMs include use in the fabrication of corrosion resistive coatings, [17][18][19] as active or passive elements in electronic devices, [20][21][22] and as inks in dip pen lithography. [23][24][25][26] Additionally, SAMs can serve as models to study the properties of membranes in cell organelles, and can be used as building blocks for biomimetic systems.…”

The wire‐like properties of four S‐(4‐{2‐[4‐(2‐phenylethynyl)phenyl]ethynyl}phenyl) thioacetate derivatives, PhC≡CC6H4C≡CC6H4SAc (1), H2NC6H4C≡CC6H4C≡CC6H4SAc (2), PhC≡CC6H2(OMe)2C≡CC6H4SAc (3) and AcSC6H4C≡CC6H4C≡CC6H4SAc (4) (Figure 1), all of which possess a high degree of conjugation along the oligo(phenyleneethynylene) (OPE) backbone, were investigated as self‐assembled monolayers (SAMs) on gold and platinum electrodes by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The redox probe [Fe(CN)6]4− was used in both the CV and impedance experiments. The results indicate that the thiolates derived from thioacetate‐protected precursor molecules 1 and 2 form well‐ordered monolayers on a gold electrode, whereas SAMs derived from 3 and 4 exhibit randomly distributed pinholes. The electron tunnelling resistance and fractional coverage of SAMs of all four compounds were examined using electron tunnelling theory. The analysis of the results reveal that the well‐ordered SAMs of 1 and 2 exhibit higher charge‐transfer resistance in comparison to the defect‐ridden SAMs of 3 and 4. The additional steric bulk offered by the methoxy groups in 3 is likely to prevent efficient packing within the SAM, leading to a microelectrode behaviour, when assembled on a gold electrode surface. The protected dithiol derivative 4 probably binds to the surface through both terminal groups which prevents dense packing and leads to the formation of a monolayer with randomly distributed pinholes. Atomic force microscopy (AFM) was used to examine the morphology of the monolayers, and height images gave root‐mean‐square (RMS) roughness′s which are in agreement with the proposed SAM structures.

“…In other words, the capacity of the chill to absorb heat from the casting is taken as a measure of its efficiency. The Volumetric Heat Capacity (VHC), which takes into account the volume, the specific heat and the density of the chill material has been identified as an important parameter in evaluating the efficiency of the chill and the corrosion resistance of the materials [14][15][16]. It has been found by certain researchers that the chilling process adopted in casting of composites helps in improving the quality of the castings.…”

Spectral broadening and self-compression of negatively chirped visible femtosecond pulses in fused silica A I Aristov, Ya V Grudtsyn, L D Mikheev et al. ABSTRACTA review of a host of relevant literature on the composites leads to some important observations on the gap that prevails for developing the composite with increased strength to weight ratio, improved thermal properties and reduced corrosion rate with the addition of fused SiO2 dispersoid for the nickel based alloy. In the arena of engineering, metallurgists look for techniques to improve the thermal, corrosion and chemical properties of the materials. In this connection an investigation has been carried out to fabricate and evaluate the corrosion, chemical and thermal properties of chilled composites consisting of nickel matrix with fused silica particles (size 40-150 μm) in the matrix. The main objective of the present research is to obtain fine grain Ni/SiO2 chilled sound composite having very good properties. The dispersoid added ranged from 3 to 12 wt. % in steps of 3%. The subsequent composites cast in molds containing metallic and non-metallic chill blocks (MS, SiC & Cu) were tested for their microstructure, chemical, thermal properties and corrosion behavior.
