Abstract

Sustainable project management practices have garnered increasing attention in recent years. Consequently, in the age of digitalization and globalization, numerous studies extensively explore the relationship between digitalization and sustainable practice. While optimism abounds, there is insufficient research into how and what types of project managers effectively manage resources to enhance the sustainability of projects when stakeholders are engaged. Therefore, we aim to address this gap by analyzing a sample of 211 Chinese project managers involved in the China‐Pakistan Economic Corridor (CPEC). Our findings indicate that project managers with digital literacy and experience are effective at managing existing resources to promote sustainable project management practices, while project managers with financial literacy do not directly exhibit sustainable practices. Furthermore, digitally literate managers are more likely to engage in bricolage (effective resource management), whereas experienced project managers are less likely to do so in the presence of stakeholder engagement. Moreover, stakeholder engagement does not appear to moderate the relationship between project manager financial literacy and bricolage. Based on these findings, our research recommends that organizations focus on employing digitally literate and experienced project managers to effectively manage their limited resources for sustainable project management. Further practical implications are discussed. [ABSTRACT FROM AUTHOR]

Abstract

Highly efficient gas sensors fabrication having low detection limits have been one of key research area due to the industrial, environmental and other technological applications. In this study, polyaniline/bismuth doped zinc oxide (PANI/Bi‐ZnO) was prepared via inverse emulsion polymerization and it was coated over a substrate with staggered electrodes to create a highly efficient ammonia (NH3) sensor. The UV/Vis investigation, fourier transformed infrared (FTIR), raman spectral analysis, and scanning electron microscopy (SEM) were used to describe the structure and morphology of prepared samples. At room temperature, the PANI/Bi‐ZnO sensor's sensitivity to various NH3 gas concentrations ranging from 20 to 100 ppm was examined. According to the experimental findings, the PANI/Bi‐ZnO film exhibits outstanding performance of response and selectivity. The response at 20 ppm NH3 was as high as ⁓100%. The response and recovery time was also calculated at 20 ppm and was 11/15 s. The contact between p‐n heterojunctions in the composite is responsible for the exceptional sensitivity of PANI/Bi‐ZnO towards NH3 sensing. Highlights: Synthesis of Bi doped ZnO composites with PANI at room temperatureFabrication of highly sensitive and efficient resistive type ammonia sensorSelective and robust detection of ammonia by the fabricated sensorHigh sensitivity with low limit of detection offered by the sensorResponse of the fabricated sensor at 20 ppm NH3 was as high as ⁓100% [ABSTRACT FROM AUTHOR]
