Abstract

There has been a growing interest among banks and financial institutions in encouraging bank customers to use automatic teller machines (ATMs). This study attempts to identify customers′ awareness, usage patterns, reasons for using (not using) ATMs, new services required, as well as problems associated with using ATMs in Kuwait. Significant differences in attitudes and opinions among age, nationality, marital status, occupation, income, and educational level groups are also reported. Implications of the study are suggested regarding the role of electronic technologies in marketing developent. Identifies some specific marketing strategy considerations designed to ensure retail customers′ acceptance and usage of ATMs. In addition, reports recommendations for further research.

Abstract

Purpose

This study aims to investigate the inhibition performance of an aqueous extract of Matricaria recutita chamomile on the corrosion of S235JR steel in 0.5 M NaCl by using electrochemical impedance spectroscopy (EIS) and polarization measurements.

Design/methodology/approach

The inhibition performance was investigated using EIS and polarization measurements. Surface analysis demonstrates the presence of a protective layer on the steel surface in the presence of the extract. Quantum chemical parameters calculated for the molecules contained in the aqueous extract are interpreted to predict the corrosion inhibition efficiency of the considered extract.

Findings

The inhibition efficiency of chamomile aqueous extract for S235JR steel increases with increasing amounts of plant concentration and with an increase in the immersion time. The optimal inhibition efficiency of chamomile extract, 98.90 per cent, was achieved for S235JR steel when immersed in 15 per cent v/v of extract concentration for 2 h. The surface analysis in the absence and presence of the chamomile extract confirmed the formation of a protective layer on steel surface. The quantum chemical calculations allowed to explain the great inhibition efficiency values by interpreting the calculated quantum parameters.

Originality/value

This is the first study carrying out an experimental and theoretical investigation on M. recutita chamomile as a green corrosion inhibitor, with interesting potential industrial applications.
