Abstract

Purpose

This study aims to investigate the combinations of religiosity, cosmopolitanism and perceived destination image leading to satisfaction and loyalty amongst Muslim consumers within the Maldivian tourism and hospitality context.

Design/methodology/approach

Using fuzzy-set qualitative comparative analysis (fsQCA), this study reveals that diverse combinations of religiosity, cosmopolitanism and destination image dimensions stimulate satisfaction and loyalty in Muslim consumers.

Findings

Multiple recipes can be used to design compelling destinations that balance the desire for religiosity and cosmopolitanism characteristic of contemporary Muslim consumers. The results confirm the applicability of complexity theory in explaining Muslim consumer behaviour within the Islamic destination context.

Practical implications

Several implications for the hospitality and tourism industry are drawn from the results, with suggestions for future research provided. Each fsQCA recipe identifies distinct suggestions to shape the design of destination attributes and hospitality offerings to stimulate consumer satisfaction and loyalty.

Originality/value

Complexity theory was applied to assess the complex causal relationships among Muslim consumers’ religiosity, perceived destination image, cosmopolitanism, satisfaction and loyalty.

Abstract

Purpose

The purpose of the study is to assess the familiarity and utilization of open access resources among library users of Cochin University of Science and Technology (CUSAT), Kochi, and Pondicherry University (PU), Puducherry.

Design/methodology/approach

Data for the study were collected via a well-structured questionnaire. For this study, 250 questionnaires were administered among library users of each CUSAT and PU through incidental sampling. From CUSAT and PU, 180 and 160 questionnaires, respectively, were considered for data analysis.

Findings

The study reveals that majority of the respondents, i.e. 77.78 and 80 per cent of CUSAT and PU, respectively, believe that they are familiar with the concept of open access (OA). 70.56 per cent respondents from CUSAT and 71.88 per cent users from PU are aware that their library has an OA repository. However, majority of the respondents, i.e. 65 and 70.63 per cent users from CUSAT and PU, respectively, use OA resources. Among OA resources, electronic theses and dissertations are the most preferred ones consulted by 56.67 and 62.50 per cent respondents, respectively, from CUSAT and PU. 60.56 per cent respondents from CUSAT followed by PU (52.50 per cent) cited “screen reading” as a main barrier in accessing OA resources.

Originality/value

Both the universities under study have created and maintained the OA institutional repository for disseminating their institutional intellectual output. This study explores awareness and use of OA resources among library users of CUSAT and PU. The study concludes with some suggestions for utmost utilization of OA resources among library users.

Abstract

Purpose

The purpose of this paper is to focus on the removal of hexavalent chromium [Cr(VI)] from wastewater by using activated carbon-supported Fe catalysts derived from walnut shell prepared using a wetness impregnation process. The different conditions of preparation such as impregnation rate and calcination conditions (temperature and time) were optimized to determine their effects on the catalyst’s characteristics.

Design/methodology/approach

The catalyst samples were characterized using thermogravimetric analysis, scanning electron microscopy and Fourier transform infrared spectroscopy. The adsorption of Cr(VI) by using using activated carbon supported Fe catalysts derived from walnut shell as an adsorbent and catalyst was investigated under different adsorption conditions. The parameters studied were contact time, adsorbent dose, solution pH and initial concentrations.

Findings

Results showed that higher adsorption capacity and rapid kinetics were obtained when the activated walnut shell was impregnated with Fe at 5 per cent and calcined under N2 flow at 400°C for 2 h. The adsorption isotherms data were analyzed with Langmuir and Freundlich models. The better fit is obtained with the Langmuir model with a maximum adsorption capacity of 29.67 mg/g for Cr(VI) on Fe5-AWS at pH 2.0.

Originality/value

A comparison of two kinetic models shows that the adsorption isotherms system is better described by the pseudo-first-order kinetic model.

A new electrochemical analysis based on ß-cyclodextrin (ß-CD) was developed for penicillin V (Peni-V) using polyaniline as a conducting polymer.

Abstract

Purpose

A new electrochemical analysis based on ß-cyclodextrin (ß-CD) was developed for penicillin V (Peni-V) using polyaniline as a conducting polymer.

Design/methodology/approach

The preparation of modified electrode involves the incorporation of β-CD with membrane of polyaniline. Polyaniline, incorporating β-CD, was prepared by electrochemical polymerization method in a medium of hypochloride. Cyclic voltammetry and electrochemical impedance have been used to characterize this sensor. The detection and the kinetic study of modified platinum electrode are evaluated.

Findings

Results clearly indicate that β-CDs interfere with the polymerization mechanism with an inhibition factor. The inclusion phenomenon of β-CDs has been studied and applied to detect Peni-V. The principle of this electrochemical sensor is based on the chemical properties of β-CD, which were studied using the cyclic voltammetric method and impedance spectroscopy. The electrochemical behavior of Peni-V at concentrations between 10–8 and 10–2 M was measured versus Ag/AgCl at pH 7.4 and 30°C in a phosphate alkaline buffer. Relationship of Peni-V concentration in logarithmic mathematical form with current in potentiometric method and with resistance in impedimetric method were obtained.

Originality/value

The present study showed that the Pt electrode modified with Polyaniline–β-CD was an excellent candidate for sensitive penicillin analysis. The proposed electroanalytical technique is rapid, simple and inexpensive.

Abstract

Purpose

The main purpose of this paper is to investigate the adsorption properties of CoFe1.9Mo0.1O4 magnetic nanoparticles (CFMo MNPs) using, anionic dye “congo red (CR)” as a model of water pollutants.

Design/methodology/approach

The magnetic nano-adsorbent was synthesized via sol-gel process. Different techniques including; Fourier transform infrared spectroscopy, point of zero charge, scanning electron microscope and X-ray powder diffraction were used to characterize the prepared adsorbent. Adsorption experiments were conducted in batch mode under various conditions (contact time, shaking speed, initial dye concentration, initial solution pH, solution temperature and adsorbent amount) to investigate the adsorption capability of CFMo MNPs for CR.

Findings

The results showed that, CFMo MNPs could successfully remove more than 90% of CR dye within 20 min. Adsorption kinetics and isotherms were better described using pseudo-second-order (PSO) and Langmuir models, respectively. The maximum adsorbed amount (qmax) of CR dye was 135.14 mg/g. The adsorption process was found to be endothermic and spontaneous in nature as demonstrated by the thermodynamics ( ΔGo, ΔHoand ΔSo).

Practical implications

This study provided a good example of using an easily separated magnetic nano-adsorbent for fast removal of a very toxic organic pollutant, congo red, from the aquatic environment

Originality/value

The employment of Mo-doped cobalt ferrite for the first time for removing hazardous anionic dyes such as congo red from their aqueous solutions.

This paper aims to focus on the development and characterization of a new electrochemical sensor, designed for the detection of methylene blue present in aqueous medium.

Abstract

Purpose

This paper aims to focus on the development and characterization of a new electrochemical sensor, designed for the detection of methylene blue present in aqueous medium.

Design/methodology/approach

This sensor is obtained through the coupling of a polymeric membrane and an ion-sensitive electrode (platinum electrode). The preparation of the polymeric membrane involves the incorporation of a receptor: β-cyclodextrin (β-CD), a polymer (polyvinylchloride) and a plasticizer (dioctylphtalate). Cyclic voltammetry method (CV) was used to investigate the electrical properties of this electrochemical sensor. The effect of the experimental parameters such as dye initial concentration, scan rate, interfering elements presence and additional Nafion membrane presence was investigated in this paper.

Findings

The results are interesting because the developed sensor gives a linear response in concentrations range of 10−13 M–10−3 M with a good correlation coefficient of 0.979 and a detection limit of 10−13 M, which reflects the sensitivity of this sensor to the target element. The sensibility value is equal to 2. 40 µA mol−1 L.

Originality/value

The present study has shown that the modified electrode is a very good candidate in terms of price, sensibility and reproducibility for the construction of the sensitive sensor for the control of wastewater containing methylene blue.
