AbstractEnvironmental and social awareness are the key elements of the sustainable tire industry. End-of-life tire (ELT) waste flow is an important environmental problem worldwide since it produces severe air, water, and soil pollution issues. Significant advancements have been made in ELT management in the last few years. As a result, ELTs should not only be regarded as waste but also as a source of environmentally friendly materials. Besides, sound ELT management has vital importance for circular economy and sustainable development. Over the last decade, ELT management has attracted many researchers and practitioners. Unfortunately, a comprehensive review of the ELT management area is still missing. This study presents the first critical review of the whole ELT management area. It aims to present an extensive content analysis overview of state-of-the-art research, provide its critical analysis, highlight major gaps, and propose the most significant research directions. A total of 151 peer-reviewed studies published in the journals between 2010–2020 are collected, analyzed, categorized, and critically reviewed. This review study redounds comprehensive insights, a valuable source of references, and major opportunities for researchers and practitioners interested in not only ELT material flow but also the whole waste management area.

AbstractPhotocatalytic N2 reduction has emerged as one of the most attractive routes to produce NH3 as a useful commodity for chemicals used in industries and as a carbon-free energy source. Recently, significant progress has been made in understanding, exploring, and designing efficient photocatalyst. In this review, we outline the important mechanistic and experimental procedures for photocatalytic NH3 production. In addition, we review effective strategies on development of photocatalysts. Finally, our analyses on the characteristics and modifications of photocatalysts have been summarized, based on which we discuss the possible future research directions, particularly on preparing more efficient catalysts. Overall, this review provides insights on improving photocatalytic NH3 production and designing solar-driven chemical conversions.

Abstract The National Institute on Aging (NIA) at the National Institutes of Health, Department of Health and Human Services, is the federally designated lead agency on aging research, and has supported significant research on aging as a life-long process. In the last five years, NIA experienced a tripling of its budget. Although much of this funding is targeted to Alzheimer’s disease (AD) and AD related dementias (ADRD) research, there was an increase in funds allocated to non-AD research in keeping with the overall growth of NIH. This symposium will provide a forum for exploration of the implications of the budget increases for the general research community. It will involve NIA’s senior staff discussing research priorities and programs supported by the Institute. A question-and-answer session will follow brief introductory remarks on current funding and future priorities and research directions of NIA.

The rapidly rising demand for fiber-reinforced plastics (FRPs) has led to large volumes of manufacturing and end-of-life waste. Recycling fiber-reinforced thermosets is very difficult owing to their complex structure and heterogeneity. Landfill and incineration have become the most commonly used methods for eliminating non-degradable FRP waste, which adversely affects the environment and ecology. The purpose of this review is to evaluate end-of-life FRP recycling technologies in terms of optimizing the reuse/recycling of resources and eliminating waste, thereby improving FRP waste management. The technical progress made in the recycling of thermosetting composites is reviewed, including mechanical, thermal (pyrolysis and fluidized-bed), and chemical (critical fluid and low-temperature solvent) methods. The technical feasibility of each method was compared, and the economic and environmental impacts were considered. The challenges and opportunities facing the establishment of a composite recycling market in the future are examined. Finally, we provide a comprehensive summary of the scope of each recycling method.

Antecedents And Consequences

Online word-of-mouth (WOM) has received significant research attention as the Internet has rapidly developed. Owing to specific Internet platforms such as consumer reviews sites and social network sites, online WOM spreads much more quickly and widely than traditional WOM, and that phenomenon ultimately makes online WOM play a key role in a consumer's purchase decision. In this chapter we present an overview of previous research on online WOM to facilitate future research in this area. In this review, previous researches are divided into three streams, i.e., (1) the effectiveness of online WOM, (2) the valence of online WOM, and (3) the antecedents and consequences of online WOM. Also, two possible future research directions are suggested at the end the chapter.

Background: The literature on the situation of palliative and end-of-life care in the Arab and Islamic world, including Egypt, is limited and does not present a clear picture of the cultural context. This report aims to portray the palliative and end-of-life care situation in Egypt, focusing on the nursing viewpoint. First, we describe health- and illness-related cultural, religious, and ethical issues. Second, we present an overview of the healthcare and nursing system in Egypt. Third, we discuss the situation of palliative and end-of-life care, highlighting the shortcomings of existing literature. Finally, we delineate country-specific recommendations to improve the palliative and end-of-life care situation at the level of policy, education, and research. Countries with similar healthcare, cultural, legal, religious, economic, or ethical contexts may benefit from the recommendations made in this study.
