22. Exploring structural, magnetic and dielectric properties of Ba1−xCoxFe12O19 hexaferrites.

Author

Kalariya, Aryan, Gupta, Tanuj, Chauhan, Chetna C., and Jotania, Rajshree B.

Abstract

This article presents a comprehensive investigation into the structural, magnetic, and dielectric properties of Ba1−xCoxFe12O19 (x = 0.00, 0.10, 0.20, 0.30, 0.40 and 0.50) prepared at 1100 °C using the heat treatment method. The FTIR analysis revealed the formation of the ferrite phase. XRD analysis provided valuable crystallographic parameters and confirmed the formation of M-type hexaferrites along with a BaFe2O4 phase. TGA investigations elucidated the thermal stability after 600 °C. VSM measurements unveiled the variation in magnetic saturation with cobalt substitutions from 24.390 to 41.629 Am2 kg−1; coercivity from 1508 to 3577 Oe. Formed samples are magnetically hard in nature. The dielectric measurements indicate that the conduction observed at low frequencies can be attributed to the presence of grain boundaries, while the conduction observed at higher frequencies is mostly influenced by the grains themselves. All samples have a frequency-dependent increase in AC conductivity. These findings contribute to the understanding of its potential applications in the automotive industry, sensors, biomedical applications and related fields. [ABSTRACT FROM AUTHOR]

28. Evaluating Barriers to the Adoption of Delivery Drones in Rural Healthcare Supply Chains: Preparing the Healthcare System for the Future

Author

Koshta, Nitin, Devi, Yashoda, and Chauhan, Chetna

Abstract

Emerging technologies, such as delivery drones have enormous potential to revolutionize the rural healthcare supply chain (RHSC) and assist the countries in achieving sustainable development goal 3: good health and well-being. The advantages of delivery drones include faster delivery, high responsiveness, and a lack of dependence on road infrastructure. Given these advantages, prior literature on drone delivery has extensively explored their applicability in last-mile delivery from the e-commerce or retailer's perspective. However, their applicability in RHSC from an academic as well as practical perspective is still at a nascent stage. The present study fills this gap by examining the barriers inhibiting the adoption of delivery drones in RHSC using the Grey Decision-Making Trial and Evaluation Laboratory technique. The results suggest that “lack of government regulations” is the most critical barrier. The study findings indicate that seven barriers are causal, and six are the effect barriers. “Limited load carrying capacity,” “low flight range,” and “difficulty in flying in adverse weather conditions” are the most prominent cause barriers. Moreover, “lack of skilled manpower,” “limited accuracy of navigation system,” and “lack of leadership commitment” are the most prominent effect barriers. We also perform sensitivity analysis to prove the robustness of the study output. The study results provide an in-depth understanding to the decision-makers and policymakers to help pave the way for the successful adoption of delivery drones in RHSC.

30. Circular economy business models as pillars of sustainability: Where are we now, and where are we heading?

Abstract

The prior literature has discussed the benefits of the circular economy business model (CEBM) while working to streamline the environmental aspect, touching upon the social aspect and improving the economic aspect. These aspects have been widely recognised as pillars of sustainability. Thus, prior scholars have sought to identify the relationship between the CEBM and sustainability. However, the extant literature, which remains relatively nascent, has failed to clarify this linkage for each pillar of sustainability. To address this lacuna, we followed a systematic literature review (SLR) approach to determine the current state of research on the CEBM and sustainability. Our study identifies and presents the thematic foci in the prior literature, which highlight the linkages between the CEBM and the pillars of sustainability. These thematic foci include the CEBM and sustainability, the CEBM and the environmental dimension, the CEBM and the social dimension and the CEBM and the economic dimension. In addition, this SLR recognises various research gaps within each theme and offers actionable avenues for future research. We also propose a conceptual framework, rooted in social capital theory (SCT), that highlights the linkages between the CEBM and sustainability. Our findings reveal that research at the intersection of the CEBM and sustainability considers the CEBM an integral component of sustainability. We conclude by presenting our work's theoretical and practical implications, which can assist scholars and organisations to incorporate the pillars of sustainability within their CEBMs. [ABSTRACT FROM AUTHOR]

Abstract

This study examines the state of the art of the literature in the domain of food loss and waste (FLW) in food supply chains (FSC). The authors used a systematic literature review (SLR) approach to examine and synthesise the findings of the existing literature to identify the key research themes, research gaps and avenues of future research on FLW in FSC. To this end, this SLR considered 152 articles relevant for the review. The authors uncovered the extant literature in the domain by presenting the research profile of the selected studies, along with thematic analysis. The authors identified eight key themes from the extant literature. The themes range from factors responsible for FLW generation to new, emerging areas of research such as digitalisation and food surplus redistribution. The study's findings will help clarify existing practices in FSC for waste mitigation and act as a foundation for strategic and policy initiatives in this area. The findings indicate that the major factors responsible for FLW include the poor management of perishable food items, stakeholder attitudes, buyer-supplier agreements and supply chain interruptions. Some of the important implications of the study include formal guidelines and policy-level interventions for assisting the accurate quantification of FLW along with an impetus on digitalisation to reduce FLW. The study concludes with the development of a research framework to assist future research in this domain. (c) 2021 The Author(s). Published by Elsevier Ltd.

Abstract

A series of Erbium substituted X-type Ba 2 Co 2 Er x Fe 28- x O 46 (x = 0.00, 0.04, 0.08, 0.12, 0.16, and 0.20) hexaferrites were prepared by the method of heat treatment. The obtained precursors were heated at 1350 °C for 6 h. XRD investigation reveals that x = 0.0 sample possesses X, W-type, and α-Fe 2 O 3 phases, while Er- substituted samples show presence of X and W phases. The room temperature Mössabuer spectra have been fitted with five sextets. A variation in saturation magnetization (M S) is explained and supported by the Mössbauer spectroscopy. The maximum values of M S (52.29 Am2/kg) and anisotropy field- Ha (1370 kA/m) are found for x = 0.12 composition. Similarly, the maximum relative area (~69%) for spin up sites (k + a + b) is also found for x = 0.12 composition. Low frequency (20 Hz–2 MHz) dielectric response of all samples show normal behavior of ferromagnetic materials. The dielectric measurements reveal that the conduction in low frequency is due to grain boundary contributions and at the higher frequency it is due to grain contributions. AC conductivity is found to increase with frequency in all prepared hexaferrites. The substituted compositions can have potential applications in filter application due to soft ferrite behavior and low dielectric loss tangent. [ABSTRACT FROM AUTHOR]
