This study aims to fabricate multiwalled carbon nanotubes (MWCNTs)-mediated polyvinyl alcohol (PVA) composite films using the solution casting approach.

Abstract

Purpose

This study aims to fabricate multiwalled carbon nanotubes (MWCNTs)-mediated polyvinyl alcohol (PVA) composite films using the solution casting approach.

Design/methodology/approach

The prepared films were evaluated for diverse structural, surface, optical and electrical attributes using advanced analytical techniques, i.e. electron microscopy for surface morphology, Fourier transform infrared spectroscopy for tracing chemical functionalities, x-ray diffraction (XRD) for crystal patterns, water contact angle (WCA) analysis for surface wettability and UV visible spectroscopy for optical absorption parameters. The specimens were also investigated for certain rheological, mechanical and electrical properties, where applicable.

Findings

The surface morphology results expressed a better dispersion of MWCNTs in the resultant PVA-based nanocomposite film. The XRD analysis exhibited that the nanocomposite film was crystalline. The surface wettability analysis indicated that with the inclusion of MWCNTs, the WCA of the resultant nanocomposite film improved to 89.4° from 44° with the pristine PVA film. The MWCNTs (1.00%, w/w) incorporated PVA-based film exhibited a tensile strength of 54.0 MPa as compared to that of native PVA as 25.3 MPa film. There observed a decreased bandgap (from 5.25 to 5.14 eV) on incorporating the MWCNTs in the PVA-based nanocomposite film.

Practical implications

The MWCNTs’ inclusion in the PVA matrix could enhance the AC conductivity of the resultant nanocomposite film. The prepared nanocomposite film might be useful in designing certain optoelectronic devices.

Originality/value

The results demonstrated the successful MWCNTs mediation in the PVA-based composite films expressed good intercalation of the precursors; this resulted in decreased bandgap, usually, desirable for optoelectronic applications.

Abstract

Purpose

Drawing on the self-determination theory, this cross-cultural study aims to examine the associations between the dualistic framework of work passion and work outcomes (job satisfaction, job engagement and workaholism).

Design/methodology/approach

Using data from a time-lagged design with two-waves, service organizations employees of the UAE (n = 150) and Canada (n = 154) participated in the study. Hierarchical regression analysis is used to analyze the associations among the variables.

Findings

The study results support the harmonious and obsessive passion relationships with the identified work outcomes. In both the UAE and Canada, harmonious and obsessive passion predicted all three hypothesized work outcomes (workaholism, job satisfaction and job engagement). The study also acknowledged various culture-specific work passion effects.

Research limitations/implications

The study encompasses the dichotomy of the work passion paradigm to compare between East and West. The examination of the work passion results offers a precise method to examine in what manner the two types of passion is linked to different work outcomes. Harmonious and obsessive passion is associated with negative (workaholism) and positive (job satisfaction and job engagement) outcomes. Accordingly, the findings strengthen the conceptual outline of the passion construct. Moreover, the research highlighted the importance of enriching the organization's environment with passionate human capital. This study shall help the decision-makers to formulate the suitable strategies to imbibe passion within the work culture.

Originality/value

This study contributes to the literature by being the first to compare the influence of harmonious and obsessive passion on work outcomes between the East and West cultures. Also, in this study, we draw upon the self-determination theory to investigate how work passion affects employees' work outcomes in a cross-cultural setting.

Abstract

Purpose

The impact of the coronavirus disease 2019 (COVID-19) pandemic on architectural education (AE) was investigated, and a framework was proposed to reduce the impacts' negative consequences.

Design/methodology/approach

Systematic literature review, bibliometric and content analyses were combined to gain an in-depth understanding of the effects of the pandemic on AE and projections for its future. Relevant documents were extracted from the Web of Science (WoS) database. Bibliometric connections in the context of AE and COVID-19 pandemic were explored using text-mining and content analysis was performed.

Findings

The challenges, development tendencies and collaboration networks in AE during the pandemic were quantitatively and qualitatively analyzed. The most influential articles, journals, authors and countries/regions were highlighted using a bibliometric analysis. The analysis of keyword tendencies and clusters indicates that new concepts have emerged in AE research during the pandemic involving online, in-person and hybrid education. Using content analysis of 57 subtopics, 39 (18) were categorized as having negative (positive) effects. A comprehensive mitigation framework was designed to reduce the impact of the pandemic on AE.

Research limitations/implications

The study findings can enable practitioners to construct effective solutions to COVID-19- and other disaster-related problems regarding AE. The implications, obstacles and mitigation framework presented can help identify gaps in the literature and guide further research.

Originality/value

This paper presents the first bibliometric and content analysis of AE and COVID-19 pandemic-related studies published from January 2020 to June 2022 to highlight several research directions and academic development within the field.
