Experimental and theoretical studies on corrosion inhibition of 4-amidinophenyl-2,2′-bifuran and its analogues in acidic media

Abstract

Corrosion inhibition studies of carbon steel (CS) in 1 M HCl by newly synthesized bichalcophene compounds namely; 4-(2,2′-bifuran-5-yl)benzamidine (MA-0947) and 6-(2,2′-bifuran-5-yl)nicotinamidine (MA-0941) and 6-[5-(thiophen-2-yl)furan-2-yl]nicotinamidine (MA-0940).

Impact of some pyrrolidinium ionic liquids on copper dissolution behavior in acidic environment: experimental, morphological and theoretical insights

“…In addition, it's essential to deduce the presence of C, O and Cu peaks in the EDX graphs of the copper surface matching to the sample inundated for 12 h. In solutions involving the favorable concentration of the ionic liquids, the creation of a thin protective lm of ILs is matching with the SEM micrographs. 49 3.6.2 Atomic force microscopy (AFM). Further morphological evaluation of the copper surface was applied via AFM in the presence and absence of the ILs with concentrations (0.05 mM) aer inundation 12 h. The AFM micrographs were shown in Fig.…”

A combination of experiment and theoretical methods to study the novel and low-cost corrosion inhibitor 1-hydroxy-7-azabenzotriazole for mild steel in 1 M sulfuric acid

“…Mild steel has a wide range of applications in production and life because of its excellent properties. [1][2][3][4][5] These include the production of various building components, containers, tanks, furnaces and agricultural machinery, in addition to various heat exchange equipment, heat transfer equipment and cooling equipment, etc. However, thermal equipment such as boilers and heat exchangers gradually form various types of dirt during use, and the poor thermal conductivity of this dirt causes the local temperature of the furnace tubes to rise, which reduces the strength of steel materials and oen causes tube explosion accidents as well as affecting the boiler operation.…”

Experimental and theoretical investigation on corrosion inhibitive properties of steel rebar by a newly designed environmentally friendly inhibitor formula

“…Previous investigations have indicated that the DNP basis set is of comparable quality to the 6-31G Gaussian basis set and it is more accurate than the Gaussian basis set of the same size. [46][47][48][49] The integration accuracy and the self-consistent eld tolerance were both set as ne. Core treatment was used to all electrons.…”
