Abstract

The prototypical toxic dye rhodamine B (RhB) is perhaps one of the most abundant pollutants in industrial wastewater. Its efficient photocatalytic degradation through composite photocatalysts is crucial for environmental remediation. Here, we synthesized quaternary Bi5O7I/Bi(IO3)3/Bi2(IO4)(IO3)3/BiOIO3 bismuth iodate composites through facile hydrothermal and solvothermal methods. The coexistence of multiple bismuth iodate phases was confirmed by x-ray diffraction analysis, room temperature Raman, and Fourier-transform infrared spectroscopy. The desired chemical states of Bi, I, and O inside the composites were confirmed by x-ray photoelectron spectroscopy. Field emission electron microscopy revealed flower-shaped nanosheet morphology for the composite synthesized at 120 °C, whereas randomly shaped nanoparticles with an average size of 80 nm were formed in the composite calcined at 400 °C. High-resolution transmission electron microscopy further corroborated the existence of multiple phases in the composites. The diffuse reflectance spectroscopy confirmed the optical absorption edges of the composites to be located within the visible range of 1.68–3.16 eV. The flower-shaped quaternary bismuth iodate composite demonstrated 100% degradation of RhB dye within 40 min of optical exposure. This quaternary bismuth iodate composite is suitable for solar harvesting-driven toxic dye remediation. [ABSTRACT FROM AUTHOR]

30. Comprehensive First-Principles Modeling of Experimentally Synthesized BiPO4Polymorphs

Abstract

Here, we present a theoretical and experimental investigation of hexagonal P3121 and monoclinic P21/nbismuth phosphate BiPO4(BPO). The Hubbard U-corrected density functional theory (DFT+U) failed to tune the electronic band gap of BPO due to the negligible contribution of Bi 5d orbitals near the band edges of BPO. The Heyd–Scuseria–Ernzerhof (HSE06) hybrid functional with Hartree–Fock exact-exchange mixing αHF= 25% suffered from band gap overestimation. The inclusion of spin–orbit coupling (SOC) and αHFtuning in the screened hybrid functional modeled the optical absorption and band gap in diffuse reflectance measurements. The experimentally measured indirect nature and magnitude of the band gap were validated from the SOC-incorporated tuned hybrid functional-based electronic band structure (BS) and density of states (DOS) simulations. The experimental Raman peaks were identified in reliable Raman tensor simulations. The simulated phonon BS and DOS from the finite difference supercell approach confirmed the dynamical stability and explained the infrared absorption of BPO, respectively. The mechanical stability was probed by an elastic tensor simulation with a sufficiently high energy cutoff. Overall, this work may help to understand the experimentally synthesized BPO polymorphs from a theoretical standpoint.

39. Challenges of Power Dominance in the GMRR: The Perspective of Pakistan’s Small Garment Manufacturers

Author

Gyamfi, Rufus Yaw, Jahan, Sharmin, Nguatem, Bernard, Vhondo, Fungai, Gyamfi, Rufus Yaw, Jahan, Sharmin, Nguatem, Bernard, and Vhondo, Fungai

Abstract

Purpose: The purpose of the study is to identify the challenges that small garments manufacturers in Pakistan face in an IOR with large retailers regarding power dominance. The paper also seeks to examine how those garment manufacturers can use the Boundary Control Systems as a strategic response to power dominance. Methodology: The study is Qualitative, Exploratory in nature. It adapts critical realism as its research philosophy while developing the study with an Abductive Approach. The data for this paper was collected through related literature, articles, and a series of semi-structured interviews. The collected Empirical Data was analyzed using Creswell's Six Steps method. Findings: The paper explores the challenges faced by the small garments manufacturers in an IOR with large retailers in the Garments Industry of Pakistan, which include the struggle to have fair pricing, dominant behavior of the retailer, over-controlling inspections of the production, unavailability of resources to manage the production scale, overly strict sanctions or price cut by the retailers, and misunderstandings created by cultural and lingual diversity. These challenges almost always start from the Negotiation stage of the collaboration leaving the small garments manufacturer little to no room for mitigating them. The most effective strategy that the small garments manufacturers can adopt while dealing with power dominance. It is to apply Boundary Systems as early as the Negotiation Stage to prevent the retailer from imposing opportunistic behavior. Involving Boundary Spanners can be useful to have better control over the challenges. Originality and Contribution: The paper attempts to explore the fairly under-studied area of power dominance between small garments manufacturers and large retailers working in the developing garments manufacturing-supplying industry in Pakistan and how Boundary Systems can be used in this dynamic. A significant lack of awareness and studies were identifi

Originality and Contribution: The paper attempts to explore the fairly under-studied area of power dominance between small garments manufacturers and large retailers working in the developing garments manufacturing-supplying industry in Pakistan and how Boundary Systems can be used in this dynamic. A significant lack of awareness and studies were identified while researching for this study. Hence this paper can be considered a new and fresh way to look at the issue that has been previously undermined. And a contribution to the literature and future researchers to further the studies in this area.
