A detailed computational exploration and experimental surface/electrochemical analyses of mild steel functionalized by zinc-aminotris methylene phosphonic acid complex film

Bichannel design inspired by membrane pump: a rate booster for the conversion-type anode of sodium-ion battery

“…1a illustrates the synthesis route of CPOC@C. By sharing the lone electron pairs of oxygen and nitrogen atoms in ATMP molecules with the empty orbital of divalent cobalt cations ( i.e. , Co 2+ ), 19,20 Co( ii )-ATMP complexes are formed (Fig. S1, ESI†), which tend to flocculate in DMF solution and slowly precipitate into nanoparticles (Fig.…”

Corrosion comparison of free and roller surfaces of Fe70Si8B12Nb10 amorphous ribbon

“…Because the electric resistance of SiO 2 is higher than that of FeO x , 44,45 it is explained that the R in of the RS from the EIS circuit is higher than that of the FS. The electrochemical reaction of Fe in NaCl solution is as follows: 46,47 2Fe-4e À ¼ 2Fe 2+ 2H 2 O + O 2 + 4e À ¼ 4OH À SiO 2 is an acidic oxide that has a tendency to react with hydroxide to form silicate. 48 Therefore, there is a greater amount of pitting of the RS as compared to the FS, and the protective effect of the outer lm on the RS is weak.…”

Salen type additives as corrosion mitigator for Ni–W alloys: Detailed electronic/atomic‐scale computational illustration

“…A noticeable larger negative value of E ads = −195.55 kcal/mol (PPD) infers that the adsorbed organic layer on the alloy surface is spontaneous and more stable [52], then the earlier molecular layer (OPD). Moreover, this higher negative value ( E ads = −195.55 kcal/mol) evidence the fact that mere amount of energy is required for the PPD molecule for adsorption onto the Ni–W alloy surface [48] intensifying the surface coverage area, thus providing a durable shield against corrosive suppressing agents [53].…”
