“…Plant-based or natural polymers are potential biosorbents for the removal of Pb(II). The main advantages of plant-based biosorbents are high porosity, large speci c surface area, and easy physical adsorption of heavy metal ions 17 . The sorption of Pb(II) by a biosorbent might be attributed to the presence of polar functional groups of lignin, proteins, carbohydrates, and phenolic compounds that have carboxyl, hydroxyl, sulfate, phosphate, and amino groups.…”

Biosorbent from a plant-based material with characterized properties is important to remove heavy metals hence reduce the impact on humans and aquatic life. This study proposes to remove Pb(II) in a synthetic aqueous solution using characterized plant-based raw Leucaena leucocephala pod (LLP) via adsorption experiment. The effects of pH synthetic aqueous solution and raw LLP dosage on Pb(II) adsorption were investigated. The characteristics of raw LLP before and after adsorption of Pb (II) were also studied. It was found that the highest adsorption capacity of Pb(II) was obtained at pH 5 of synthetic solution with 1.1 mg/g adsorption capacity. Meanwhile, the optimum dosage of raw LLP was 40 g/L at 30 min retention time, resulting in 93% of Pb(II) removal. Optimum removal of Pb(II) using raw LLP in this study was obtained under low retention time of adsorption process compared to other studies using others plant based biosorbent but comparable in terms of heavy metal removal. Raw LLP can be effectively used directly without modification as a biosorbent in removing Pb(II) in industrial waste, hence provides an alternative method for pollutants removal which is safe for the environment and abundantly available.

Industrial symbiosis (IS) allows the use of the resources of a productive chain, based on collaboration between companies, finding ways to use the waste of one as inputs or raw materials for the other entity. IS seeks to generate environmental sustainability, maximize resources, and generate social, environmental, and economic benefits based on the physical exchanges of waste, residues, and materials, which generate various advantages for companies and environmental benefits for society. Over the years, research has been conducted worldwide on the implementation of IS in business settings and case studies related to IS in countries with strong economies; however, no papers mapping studies on IS that are focused on emerging and frontier market countries have been identified, and academic literature on research in these countries is also scarce. In this research, an in-depth review of the literature on IS cases in emerging and frontier market countries was conducted to provide future researchers with information on the similarities, weaknesses, strengths, and elements to consider in addressing the topic and closing research gaps in the area. In addition, a mapping was made of the evolution of studies on IS according to country, economic activity, distribution by journal, year of publication, methods used, barriers and drivers in the case studies, and the importance of this topic in the current academic context. In Asian and developing countries, the integration of companies and economic activities takes place in industrial parks, and they have legislation and government regulations that support IS. On the other hand, in the United States and Africa, integrating various sources such as energy, water, coal, and waste in industrial environments is at an early stage of development, and opportunities are being identified to promote IS between companies. This research interests a broad audience, including investors, regulators, policymakers, and researchers interested in fostering IS in emerging and frontier market countries as a mechanism for industrial and economic development.

“…In this scenario, single‐domain magnetic nanoparticle showing superparamagnetism at room temperature represent an interesting playground for fundamental study. Moreover, the wide presence of MNPs in nature and in living systems makes them of interest in different branches of science with a large spectrum of applications: paleomagnetism (Lagroix & Guyodo, 2017; Newell, 2017; Yan et al., 2012), geology (Morales et al., 1997), mineralogy, cultural heritage (archaeology, paintings) (Rao et al., 2015), catalysis (Arizzi et al., 2015; Cunha et al., 2018; Gawande et al., 2013; Skliri et al., 2018), surface chemistry (Lykaki et al., 2018; Simo et al., 2018; Turcheniuk et al., 2013), biomagnetic separation (Fields et al., 2016; Hofman et al., 2017), medicine theragnostic of tumours (Arora & Bandopadhyaya, 2018; Gazeau et al., 2008; Hameed et al., 2018) and tissue engineering (Cagil et al., 2018; Leferink et al., 2018; Pankhurst et al., 2003), magnetic recording (López‐Ortega et al., 2015; Malek et al., 2018; Manzoor et al., 2018), permanent magnets (Chahal & Samra, 2018; Li et al., 2003; Lu et al., 2007), sensors (Cao et al., 2018; Dong et al., 2018; Rocha‐Santos, 2014), ferrofluid‐based devices (Felicia & Philip, 2015; Kuzhir et al., 2017; Seol et al., 2017), high frequency power applications (Felicia & Philip, 2015; Hayashi et al., 2010; Helal et al., 2018; Mondal et al., 2016) and magneto optical devices (da Silva et al., 2019).…”

In this review article, a perspective on the immobilization of various hydrolytic enzymes onto magnetic nanoparticles for synthetic organic chemistry applications is presented. After a first part giving short overview on nanomagnetism and highlighting advantages and disadvantages of immobilizing enzymes on magnetic nanoparticles (MNPs), the most important hydrolytic enzymes and their applications were summarized. A section reviewing the immobilization techniques with a particular focus on supporting enzymes on MNPs introduces the reader to the final chapter describing synthetic organic chemistry applications of small molecules (flavour esters) and polymers (polyesters and polyamides). Finally, the conclusion and perspective section gives the author's personal view on further research discussing the new idea of a synergistic rational design of the magnetic and biocatalytic component to produce novel magnetic nano‐architectures.
