“…The use of environmentally friendly materials, in particular plant extracts, fungi, bacteria and enzymes, for the synthesis of MNPs showed numerous benefits in pharmaceutical and other biomedical applications . Green synthesis resulted also in being very cost effective and therefore can be used as a cheep suitable alternative for large‐scale production of MNPs.…”

“…Several approaches have been reported in the literature using extracts from a variety of different plant species in combination with a variety of acids and metal salts. For example aqueous extracts of Ferocactus echidne have been used to reduce silver nitrate (AgNO 3 ) to form silver nanoparticles (AgNPs) within 6 h. It has been reported that both polyphenols and ascorbic acid present in aqueous Ferocactus echidne extracts can easily reduce silver ions and can also act as capping agents to prevent the agglomeration of AgNPs . Recently, gold nanoparticles (AuNPs) have been synthesized within 30 min by reducing sodium tetrachloroaurate (NaAuCl 4 ) with extracts of Darjeeling tea leaves.…”

[a] 1Introduction Nanotechnology is one of the most active areas of modernr esearch. New applications of nanoparticles (NPs) and nanomaterials are emerging rapidly.I nt he last decade metal nanoparticles (MNPs) have played an importantr ole in the development of biofuel cells,i on batteries and (bio)sensing devices [1][2][3][4] especially in the medical diagnostics field. MNPsa re commonly described as nanosized metals with dimensions within1 -100 nm with manyo pto-electronic properties such as larger surface area-volumer atio compared to their corresponding bulk material, large surface energies,p lasmonic excitation and quantum confinement [5].H istorically,g old, silver and copper MNPs were the most largely synthesized,b ecause of the particular properties of the noble metals, followed by iron oxide MNPsf or their magnetic properties [6][7][8].Thei ntegration of green chemistry principles to nanotechnology is one of the key issues of nanoscience research.G reen synthesis has become the way for asustainable and safe production of NPs and it has been proven to be an advantegeous methodd ue to its slower kinetics, easy manipulation and control over crystal growth for stabilization of NPs [9,10].Theuse of environmentally friendly materials,inparticular plant extracts,f ungi, bacteriaa nd enzymes,f or the synthesis of MNPs showed numerous benefits in pharmaceuticala nd other biomedical applications [11][12][13].G reen synthesis resulted also in being very cost effective and therefore can be used as ac heep suitable alternative for large-scale production of MNPs.Several approaches have been reported in the literature usinge xtracts from av ariety of differentp lant species in combination with av ariety of acids and metals alts.F or example aqueous extractso fFerocactuse chidne have been used to reduce silver nitrate (AgNO 3 )t of orm silver nanoparticles (AgNPs) within 6h.I th as been reported that both polyphenols and ascorbic acid present in aqueous Ferocactus echidne extractsc an easily reduce silver ions and can also act as capping agents to prevent the agglomeration of AgNPs [12].R ecently,g old nanoparticles (AuNPs) have been synthesized within 30 min by reducing sodium tetrachloroaurate (NaAuCl 4 )w ith extracts of Abstract:I nt his paper we report on af acile,c ost effective and environmental friendly green synthesis method of gold and silvern anoparticles (NPs) by using quercetin as reducing agent.

“…Table 7 shows some of the rules extracted using the back analysis based on the DRSA. Decision rules can be defined as logical statement, very easy to understand since they are in the form of 'If… then…' sentences (Słowiński et al, 2009;Cinelli et al, 2015). In Table 7, each rule is represented with the conditions that characterize it, the resulting decision class assignment, and the cases which support it (Cinelli et al, 2015).…”

Spatial multicriteria analysis for sustainability assessment: A new model for decision making

et al. 2018

A B S T R A C TPolicy makers have to consider the sustainability perspective in strategic planning decisions. Identifyand measure the level of sustainability, through its three dimensions, is a priority. Therefore, the aim of this work is to present a new model, called GeoUmbriaSUIT, integrating Multicriteria Analysis and Geographic Information Systems, specifically developed for helping Decision Makers to take policy decisions about sustainability in planning. The model provides outputs which are easy to be understood by not experts; the evaluation path is traceable and transparent, thanks to back analysis.To better explain the potentiality of GeoUmbriaSUIT and its functioning, a case study about Malta is described. Our results showed that in four regions of Malta the best dimension was the environmental one, while only for two regions (Northern Harbour and Southern Harbour) respectively the economic and social dimensions obtained the best scores. The integration of MCDA-GIS resulted to be a useful tool for sustainability assessment.

“…Sonication has obviously added to the repertoire of methods employed in synthesis. Ag-NPs, currently obtained by different green routes [92], exhibit a remarkable antibacterial activity, whose mechanism of action has been investigated in detail as well [93]. Thus, Manjamadha and Muthukumar synthesized Ag-NPs in only 10 min using an aqueous extract of Lantana camara L. as bioreductant and capping reagent under ultrasound [94].…”

Merging Metallic Catalysts and Sonication: A Periodic Table Overview

et al. 2017

Abstract:This account summarizes and discusses recent examples in which the combination of ultrasonic waves and metal-based reagents, including metal nanoparticles, has proven to be a useful choice in synthetic planning. Not only does sonication often enhance the activity of the metal catalyst/reagent, but it also greatly enhances the synthetic transformation that can be conducted under milder conditions relative to conventional protocols. For the sake of clarity, we have adopted a structure according to the periodic-table elements or families, distinguishing between bulk metal reagents and nanoparticles, as well as the supported variations, thus illustrating the characteristics of the method under consideration in target synthesis. The coverage focuses essentially on the last decade, although the discussion also strikes a comparative balance between the more recent advancements and past literature.

A green chemistry-based classification model for the synthesis of silver nanoparticles

Abstract: The Multiple Criteria Decision Aiding (MCDA) method allows the derivation of a model that can be used for classification of existing or new production processes for silver nanoparticles in preference-ordered classes on the basis of the principles of green chemistry.
