“…Similarly, on the basis of the subject category co-occurrence network burst detection, “Science & Technology-Other Topics”, which had a burst beginning at the year of 2016, and “Engineering, Multidisciplinary”, “Engineering, Chemical”, and “Green & Sustainable Science & Technology”, with burst beginning at the years of 2014–2016, represent a new trend in the research and development of phytoremediation of HMs, and these categories can be identified as trends in the subject categories. These subject categories are generally applicable, focused on engineering, and comprehensive, and may provide evidence for the application of engineering practices to phytoremediation of HMs [36,37,38,39].…”

This paper aims to evaluate the knowledge landscape of the phytoremediation of heavy metals (HMs) by constructing a series of scientific maps and exploring the research hotspots and trends of this field. This study presents a review of 6873 documents published about phytoremediation of HMs in the international context from the Web of Science Core Collection (WoSCC) (1989–2018). Two different processing software applications were used, CiteSpace and Bibliometrix. This research field is characterized by high interdisciplinarity and a rapid increase in the subject categories of engineering applications. The basic supporting categories mainly included “Environmental Sciences & Ecology”, “Plant Sciences”, and “Agriculture”. In addition, there has been a trend in recent years to focus on categories such as “Engineering, Multidisciplinary”, “Engineering, Chemical”, and “Green & Sustainable Science & Technology”. “Soil”, “hyperaccumulator”, “enrichment mechanism/process”, and “enhance technology” were found to be the main research hotspots. “Wastewater”, “field crops”, “genetically engineered microbes/plants”, and “agromining” may be the main research trends. Bibliometric and scientometric analysis are useful methods to qualitatively and quantitatively measure research hotspots and trends in phytoremediation of HM, and can be widely used to help new researchers to review the available research in a certain research field.

“…Gas chromatography–mass spectrometry (GC–MS): In order to analyze the generated pollutants, the compositions and contents of the gas and residue after the heat-desiccation dissociation of organic impurity in waste glass were determined by GC–MS (7890A-5975C). The test of GC–MS was performed by Shiyanjia Lab . The residue samples should be extracted with a solvent before injection.…”

The heat-desiccation dissociation technology is recommended to remove the organic impurity during the recovery of waste glass. Some organic impurity attaches to waste glass and the other falls off during transportation and storage. However, their differences in pollutant release during heat-desiccation dissociation have not been reported. In this study, the products and decomposition mechanisms of different organic impurities during heat-desiccation dissociation were investigated. Organic impurity attached to waste glass produced fewer pollutants, and the components of gas and residue were simpler. The main component of gas was alanine (a nontoxic substance), accounting for 40.94%. However, the main component of gas of pure organic impurity was propene (a low-toxic substance), accounting for 28.94%. Molecular dynamics showed that the decomposition degree of organic impurity attached to waste glass was low, leading to the simpler product component. The formation of NH2 • was the main reason for the generation of alanine. Thus, the organic impurity that has fallen off should be removed before the heat-desiccation dissociation process. This study provides technological guidance for the heat-desiccation dissociation technology during waste glass recovery.

“…Compared to Azolla group, Salvinia minima Baker was capable to accumulate high concentrations of Pb, Ni and Cd but not As [ 129 , 130 ]. More than that, the ferns’ capacity to take up different metals and metalloids could allow, besides the phytoremediation of contaminated soils, the reclamation of rare elements from polluted sites [ 131 ].…”

The area of phytosynthesized nanomaterials is rapidly developing, with numerous studies being published yearly. The use of plant extracts is an alternative method to reduce the toxic potential of the nanomaterials and the interest in obtaining phytosynthesized nanoparticles is usually directed towards accessible and common plant species, ferns not being explored to their real potential in this field. The developed nanoparticles could benefit from their superior antimicrobial and antioxidant properties (compared with the nanoparticles obtained by other routes), thus proposing an important alternative against health care-associated and drug-resistant infections, as well as in other types of applications. The present review aims to summarize the explored application of ferns in nanotechnology and related areas, as well as the current bottlenecks and future perspectives, as emerging from the literature data.
