Ag3PO4as a photocatalyst has attracted enormous attention in recent years due to its great potential in harvesting solar energy for environmental purification and fuel production. The photocatalytic performance of Ag3PO4strongly depends on its morphology, exposed facets, and particle size. The effects of morphology and orientation of Ag3PO4on the catalytic performance and the efforts on the stability improvement of Ag3PO4are reviewed here. This paper also discusses the current theoretical understanding of photocatalytic mechanism of Ag3PO4, together with the recent progress towards developing Ag3PO4composite photocatalysts. The crucial issues that should be addressed in future research activities are finally highlighted.

Supplier development has been a critical supply management practice since the 1990s. In many instances, it has even become imperative for buyer firms to support and prepare their supply bases for uncertain economic and market environments, socially and environmentally conscious customers, advances in digital technologies, and increasing competition. Yet, research that approaches supplier development with the objective to advance all these dimensions in an integrated fashion is scarce. This study fills this void by exploring how a buyer firm may address these emerging challenges in its supply base. Specifically, an in-depth case study of LG Electronics explores how the firm designs and operates multidimensional supplier development activities to foster the stability and sustainability of its supply base while enhancing its core suppliers’ competitive capabilities. This chapter illustrates how supplier development can be taken to the next level, presents implications for managerial practice, and outlines promising future research avenues.

AbstractMusic has been steadily rising up the historical agenda, a product of the emergence of sound studies, the history of the senses, and a mood of interdisciplinary curiosity. This introductory article offers a critical review of how the relationship between music and politics has featured in extant historical writing, from classic works of political history to the most recent scholarship. It begins by evaluating different approaches that historians have taken to music, summarizes the important shifts in method that have recently taken place, and advocates for a performance-centered, contextualized framework that is attentive to the distinctive features of music as a medium. The second half examines avenues for future research into the historical connections between music and politics, focusing on four thematic areas—the body, emotions, space, and memory—and closes with some overarching reflections on music's use as a tool of power, as well as a challenge to it. Although for reasons of cohesion, this short article focuses primarily on scholarship on Britain and Ireland in the eighteenth and nineteenth centuries, its discussion of theory and methods is intended to be applicable to the study of music and political culture across a broad range of periods and geographies.

Grouted Semi-flexible Pavement (GSP) is a novel pavement composed of open-graded asphalt concrete grouted with high-fluidity cement mortar. Due to its excellent load-bearing and anti-rutting performance, it has great potential as anti-rutting overlay and surface in road construction. However, the understanding of GSP performance remains limited and pertinent findings are inconsistent. This article aims to provide a systematic literature review for the articles which were published between 2000 and 2020 on GSP, explore the problems in the recent research, identify knowledge gaps, and deliver recommendations for future research. The influential factors and the relative evaluation methods of GSP performance are summarized and discussed in this article.

Fluxgate magnetic sensors are especially important in detecting weak magnetic fields. The mechanism of a fluxgate magnetic sensor is based on Faraday’s law of electromagnetic induction. The structure of a fluxgate magnetic sensor mainly consists of excitation windings, core and sensing windings, similar to the structure of a transformer. To date, they have been applied to many fields such as geophysics and astro-observations, wearable electronic devices and non-destructive testing. In this review, we report the recent progress in both the basic research and applications of fluxgate magnetic sensors, especially in the past two years. Regarding the basic research, we focus on the progress in lowering the noise, better calibration methods and increasing the sensitivity. Concerning applications, we introduce recent work about fluxgate magnetometers on spacecraft, unmanned aerial vehicles, wearable electronic devices and defect detection in coiled tubing. Based on the above work, we hope that we can have a clearer prospect about the future research direction of fluxgate magnetic sensor.

Advanced Knowledge

This article explores a trend provisionally called “eco-didacticism” observable for nearly 15 years in art, design and architecture. The corpus concentrates on learning centres as buildings meant to diffuse advanced knowledge in the field of sustainable architecture. We found evidence of additional educational intentions to the pedagogical or scientific programs that these buildings have already been mandated to host and support. A variety of practices or devices have sometimes been added to the architecture, sometimes integrated, while others determine the overall structuring of these educational buildings. Seven cases of “learning centres” built in Canada between 2004 and 2018 have been screened through three epistemological filters distinguishing forms of “architectural didactics”: 1—a labeling often quantitative approach, 2—an experiential or practical approach, 3—a visually narrative or iconic approach. While outlining definitions of these Architectural Educational Strategies (AES), we offer initial explanations for their distinctive features. It appears that architects, designers and critics altogether operate on the belief that forms of architectural communication can operate as elements of a language that would be accessible to non-experts. Our conclusion indicates how future research could question the very possibility of giving lessons through formal language and aesthetic features.

Abstract Hydrofluoric acid (HF) or fluoride ion corrosion issues are often encountered in many fields, which have attracted extensive research due to its strong corrosiveness. In this paper, a critical review is presented based on recent progress on HF corrosion. In view of the discrepancy of fluoride ion compared with other ions, the special attack characteristics of fluoride ion are firstly discussed. Afterwards, the corrosion mechanisms of stainless steels, nickel-based alloys, and titanium alloys in HF solution or fluoride ion-containing environment are reviewed, and three typical corrosion behaviors are summarized, which are essentially weakening process of passivation of metallic materials. The effects of influencing factors (e.g. alloying elements, environmental factors, and stress, etc.) on HF corrosion are also discussed, which involve changes in passivation mechanism, the influence of HF attack mode and multiple damage mechanisms due to mechanical–chemical coupling. Finally, future research works on HF corrosion are proposed.

The Stability

Despite the omnipresence of inter-group conflicts, little is known about the heterogeneity and stability of individuals’ social preferences toward in-group and out-group members. To identify the prevalence and stability of social preferences in inter-group conflict, we gather quota-representative, incentivized data from a lab-in-the-field study during the heated 2016 Austrian presidential election. We assess social preferences toward in-group and out-group members one week before, one week after, and three months after the election. We find considerable heterogeneity in individuals’ group-(in)dependent social preferences. Utilizing various econometric strategies, we find largely stable social preferences over the course of conflict. Yet, there is some indication of variation, particularly when the conflict becomes less salient. Variation is larger in social preferences toward in-group members and among specific preference types. We discuss the theoretical implications of our findings and outline potential avenues for future research.
