IntroductionIn the mid twentieth century, Bush (1945) considered the difficulties a researcher faced to find the results that hundreds of researchers had attained. He observed how difficult it was to deal with great quantities of information and the increasingly time it took to keep updated and to produce academic works. Even though the Internet has been offering the tools, which could potentially solve this issue, especially via Web and the Indexation basis of journals, a kind of vicious cycle has been created that impacts the search process. There is an increasingly number of publications, easily created with online systems, to disclose the ever-growing number of scientific researches. Indexation systems like Web of Science and Scopus make millions of articles available to the public. Therefore, we can see that the situation Bush (1945) faced has not changed, once researchers are still dealing with the same difficulties to select the most relevant facts amidst immense bibliographic oceans. Consequently, the bibliometry gained traction as the researchers are trying to understand what is happening in their field of study (Tague-Sutcliffe 1992). AbstractThe scientific production on "education for sustainability" has been growing in recent years what demonstrates the attention this subject has gathered. To better understand and characterize this trend, a bibliometric study of international papers on the subject was developed. The results show that the production has been growing since the middle of the last decade, focusing on the field of the applied social sciences, environmental sciences, energy, management, engineering, humanities and psychology. Australia, United Kingdom, United States, New Zealand, Spain, Israel and Canada are the countries that stand out, and it was possible to characterize the evolution of the production in each of these countries in the last 10 years, as well as to indicate the most used journals, the associated sub-themes, the most cited papers, the most productive authors and their affiliations. This allowed us to understand how the research on "education for sustainability" is being developed, showing its level of maturity and the most frequent themes and journals that have published more papers in the area. It was also possible to identify some themes which present research opportunities. The practical results of this study serve as a guideline for researchers, helping them to explore the available bibliography and the better ways to convey their production.

“…Additionally, over 90% of REE purification occurs in China. (Dobransky, 2012;Kynicky et al, 2012;Massari and Ruberti, 2013;United States Geological Survey, 2013;Yang et al, 2013).…”

“…The methods for mining REEs ores can vary from placer mining, underground mining, open pit mining, and in situ mining (Walters et al, 2010;Sonich-Mullin, 2012). The majority of LREEs and HREEs are produced via open pit mines and in situ mining, respectively (Yang et al, 2013).…”

“…REEs with atomic number 57-63 are classified as light-rare earths (LREEs), and REEs with atomic number 64-71 are classified as heavy-rare earths (HREEs). Scandium and yttrium are usually classified as HREEs (Humphries, 2011;Yang et al, 2013;Pothen, 2014). From other work, a third category, i.e., medium-rare earths (MREEs) is used to describe samarium, europium, and gadolinium (Chen, 2011;Hatch, 2011;Tharumarajah and Koltun, 2011).…”

“…Rare-earth elements have traditionally been applied in a variety of domains and products, including catalysts, ceramics, communications, electronics, lighting, phosphors, and polishing powders (Eggert et al, 2008;Hatch, 2012;White et al, 2013). What distinguishes REEs from other elements is their particular electronic structures (i.e., 4f orbitals), which offer unique chemical, structural, and physical properties (Korinek and Kim, 2010;Graf et al, 2013;Fouquet and Martel-Jantin, 2014).…”

Life-Cycle Assessment of the Production of Rare-Earth Elements for Energy Applications: A Review

2014

View full text Add to dashboard Cite

Rare-earth elements (REEs) are a group of 17 elements with similar chemical properties, including 15 in the lanthanide group, yttrium, and scandium. Due to their unique physical and chemical properties, REEs gain increasing importance in many new energy technologies and systems that contribute to reduce greenhouse gas emissions and fossil fuel depletion (e.g., wind turbine, electric vehicles, high efficiency lighting, batteries, and hydrogen storage). However, it is well known that production of REEs is far from environmentally sustainable as it requires significant material and energy consumption while generating large amounts of air/water emissions and solid waste. Although life-cycle assessment (LCA) has been accepted as the most comprehensive approach to quantify the environmental sustainability of a product or process, to date, there have been only very limited LCA studies on the production of REEs. With the continual growth of renewable energy and energy efficient technologies, global production of REEs will increase. Therefore, reducing environmental footprints of REE production becomes critical and identifying environmental hotspots based on a holistic and comprehensive assessment on environmental impacts serves as an important starting point. After providing an overview of LCA methodology and a high-level description of the major REE production routes used from 1990s to today, this paper reviews the published LCA studies on the production of REEs. To date, almost all the LCA studies are based on process information collected from the operation of Mountain Pass facility in U.S. in 1990s and the operation of facilities in Bayan Obo, China. Knowledge gaps are identified and future research efforts are suggested to advance understanding on environmental impacts of REE production from the life-cycle perspective.

Effective and Sustainable Access to Quinolines and Acridines: A Heterogeneous Imidazolium Salt Mediates C–C and C–N Bond Formation

2019

Quinoline and acridine derivatives have been prepared using a functionalized imidazolium salt as heterogeneous catalyst. Different ketones have been coupled with 2‐aminobenzaldehydes and 2‐aminoaryl ketones under solvent‐free conditions, employing 1,3‐bis(carboxymethyl)‐imidazolium chloride as a catalyst. The protocol is simple and effective for the synthesis of a variety of nitrogen containing heterocycles (> 35 examples) with moderate to excellent yields (up to 96 %), being possible to perform the reaction in preparative scale. Additionally, 3‐acetylquinolines have been transformed, under solvent‐free conditions, into quinolyl chalcone derivatives by means of the same catalyst. Thus, the catalytic system mediates both reactions effectively in a tandem procedure. Furthermore, the catalyst is easily separated from the reaction mixture and can be reused without loss of activity (up to 8 cycles) which remarks its sturdiness. The E‐factors are in the range of 14–23, both for the formation of quinolines and for the tandem reaction, which demonstrates the sustainability of the protocols described.
