This research focuses on the mediating role of construction materials, sustainable use between the construction supply chain integration and the construction industry performance. In this concern, the case of Pakistan was considered specifically. The research design employed in this study was quantitative and a close-ended survey questionnaire was used as a research instrument. The sample size used is comprised of 300 participants and analysis was performed through the Structural Equation Modelling (SEM). The results revealed that the effect of the components of supply chain integration on the construction industry performance was statistically significant. Moreover, outcomes also substantiate the mediation role of using construction material sustainably. The scope of the research was limited to the construction industry of Pakistan; however, future research would focus on other countries and industries.

TiO nanoparticles and nanofibers have been used to carry out a comparative study of the destruction of HS gas. Effects of sulphur doping have also been incorporated to assess the maximum destruction potential of the nanomaterials. An analysis has been made in this paper to evaluate and compare the performance of pure and sulphur-doped TiO nanoparticles and nanofibers for the destruction of HS gas using photocatalysis under laboratory conditions. Regression modelling has been performed to ascertain the individual degradation rates of the nanoparticles and nanofibers. In addition, oxidation rates of HS gas using the nanoparticles and nanofibers have been used to further elucidate our findings. It was observed that the destruction potential of nanofibers was 10 times more as compared to nanoparticles.

Prefabricated construction is being pursued globally as a critically important sustainable construction technology. Prefabricated construction technology (PCT) provides opportunities to effectively manage construction waste and offers venues to address the poor productivity and lackluster performance of construction projects, which are often expected to miss their budget and schedule constraints. Despite the significant benefits inherent in the adoption of PCT, research has shown an unimpressive exploitation of this technology in the building sector. A modified version of the popular technology acceptance model (TAM) was used to understand Pakistan’s building construction industry stakeholder’s acceptance of PCT and the factors that influence its usage. Data were collected from 250 building construction experts in the industry to test the hypotheses derived from the proposed model. Data analysis using covariance-based structural equation modeling revealed that construction industry stakeholders’ perceptions of perceived ease-of-use, perceived usefulness, trust, and satisfaction all strongly influenced PCT acceptance behavior. Moreover, results also confirmed the total direct and indirect effects of the perceived usefulness and perceived ease-of-use of behavioral intention toward using PCT, with trust and user satisfaction as mediators. The results of this research are expected to serve as a guide for the construction industry stakeholders to effectively plan, strategize, encourage, and increase the adoption of PCT to achieve sustainable construction outcomes in the building construction sector.

This study draws a comparison between destruction potential of TiO 2 nano particles when its doped with Sulphur and Zirconium. When TiO 2 gets excited, it induces into electron pairs and holes and due to the presence of Sulfur in the nanoparticles, the energy of these pairs of electrons will be enhanced since S donates additional electrons during the reaction. While Zr has been found to improve the thermal stabilization of TiO 2 and it also increases its surface area. Fixed bed catalysis system was used to assess the destruction potential of H 2 S gas using S and Zr doped TiO 2 nanoparticles. The gas samples obtained were analysed using Gas Chromatography-Mass Spectroscopy to ascertain the percentage destruction of H 2 S gas before and after passing the gas samples from the doped TiO 2 nanoparticles. The results showed around 90% destruction of H 2 S gas using S-doped TiO 2 nanoparticles while doping with Zr proved to be very less effective for degradation of H 2 S gas as compared to S doped nanoparticles.
