Resumen
There is a pressing need for: (i) cleaner fuels (free of aromatics and of minimal sulfur content) or ones that convert chemical energy directly to electricity, silently and without production of noxious oxides and particulates; (ii) chemical, petrochemical, and pharmaceutical processes that may be conducted in a one-step, solvent-free manner, and that use air as the preferred oxidant; and (iii) industrial processes that minimize consumption of energy, production of waste or the use of corrosive, explosive, volatile and nonbiodegradable materials. All these needs and other desiderata, such as the in situ production and containment of aggressive and hazardous reagents, and the avoidance of use of ecologically harmful elements, may be achieved by designing the appropriate heterogeneous inorganic catalyst, which, ideally should be cheap, readily preparable, and fully characterizable, preferably under in situ reaction conditions. A range of nanoporous and nanoparticle catalysts, designed, synthesized, characterized, and tested by the authors and their colleagues, that meet most of the stringent demands of sustainable development and responsible (clean) technology is described. Specific examples that are highlighted include: (a) the production of adipic acid (precursor of polyamides and urethanes) without the use of concentrated nitric acid or the production of greenhouse gases such as nitrous oxide; (b) the production of caprolactam (precursor of nylon) without the use of oleum and hydroxylamine sulfate; and (c) the terminal oxyfunctionalization of linear alkanes in air. The topic of biocatalysis and sustainable development is also briefly discussed, and a cautionary note is sounded concerning fast screening methods for the discovery of new inorganic catalysts.

Resumen
Transition-metal (TM) complexes of new phosphines, readily prepared by a straight-forward three-step modular synthesis, were successfully employed in difficult cross-coupling reactions conducted under mild conditions (water, “open-flask”, low temperature) that aspire to meet green chemistry criteria. High yielding catalyzed by bismuth or rhodium complexes oxidative arylation of naphthoquinone gave the key 2-arylnaphthoquinone intermediates for facile bismuth triflate-catalyzed Michael addition of secondary phosphine oxides. Subsequent O-methylation and reductions of the resulting products gave access to the target air-stable phosphine ligands in good overall yields (up to 60 %).

Resumen
Computer Aided Molecular Design (CAMD) techniques have been extensively applied to design solvents for different applications. Most of the CAMD problems only aim at generating solvents that meet the predefined functionality. Nevertheless, it is important to consider the effect of solvent on the safety, health and environmental impacts during the recovery process. This paper presents a single stage CAMD framework that simultaneously quantifies the environmental impact of the solvent recovery process. The environmental impact of the process can be estimated through IChemE Sustainability Metrics. Besides, molecular properties that have an impact on the quantitative evaluation of the environmental impact of solvent recovery process are included in this framework. Weighted sum method coupled with Fuzzy Analytic Hierarchy Process (FAHP) weighting approach is employed to solve the multi-objective molecular design framework. A case study on solvent design for residual oil extraction from palm pressed fiber is presented to illustrate the proposed framework. In this work, only energy balance around multistage evaporator is incorporated into CAMD formulation as energy required to recover the solvent contributes to the largest portion of the whole process. The results show that the designed solvents simultaneously possess target functionalities and reduce the environmental impact of solvent recovery process.

Resumen
Esterification is the most important derivatization to utilise cellulose as a sustainable resource for the materials industry. Homogeneous esterification is generally the most convenient means to achieve this aim. We found that N-methyl-N-(2-methoxyethyl)pyrrolidinium acetate [P1ME][OAc] easily dissolved cellulose. To achieve the environmental benign acylation of cellulose, we attempted to design acyl donor molecules under strong base catalyst-free conditions. It was found that a [P1ME][OAc] solution of cellulose when mixed with 2,2,2-trifluoroethyl benzoates at 80°C afforded the corresponding cellulose benzoate with a perfect (3.0) degree of substitution (DS) value in almost quantitative yield. We also succeeded in preparing 4-[(4-hydroxyphenyl)diazenyl]benzoate or 4-[(4-methoxyphenyl)diazenyl]benzoate of the cellulose with a DS value of 2.38 or 2.67 by the same protocol, respectively; the DMSO solution prepared by the resulting compounds exhibited a photochromic property, although only a slight colour change from light yellow to colourless was obtained by UV irradiation.

Resumen
Traditional approaches to the development of integrated circuits involve the use and/or manufacture of toxic materials that have a potential environmental impact. An extensive research has been done to design environmentally benign synthetic polymers containing nucleic acid bases, which can be used to enhance the photoresistor technologies. Water soluble, environmentally benign photopolymers of 1-(4-vinylbenzyl) thymine (VBT) and vinylphenyl sufonate (VPS) undergo a photodimerization reaction when exposed to low levels of ultraviolet irradiation leading to an immobilization of the copolymer on a variety of substrates. Plackett-Burman design (PBD) and central composite design (CCD) were applied to identify the significant factors influencing the polymer crosslinking and dye adsorption processes, which are relevant in the fabrication of copolymer films for potential photoresist use. The PBD results assigned a maximum absorption signal of 0.67, while optimal conditions obtained in this experiment following the CCD method predictions provided a response of 0.83 ± 0.03, being a solid foundation for further use of this methodology in the production of potential photoresistors. The pH effect was relevant for low concentrations but not significant for higher concentrations. To the best of our knowledge, this was the first report applying statistical experimental designs to optimize the crosslinking of thymine-based polymers.

Resumen
An efficient, feasible, mild, affordable, and environmentally friendly method has been developed for the synthesis of biologically active compound 3-methylene-indoline-2-one from Isatin and active methylene compounds using Lipase as a Green and Biocatalyst. Biological Processes are very important to optimization to increase and improve the efficiency of cost. In this project, Malononitrile, or Dimedone reacts with Isatin in presence of lipase. The essential features of this approach are metal-free reaction, high yield, nontoxic, and less hazardous. These reactions surpass metal-catalyzed processes because these reactions have violent reaction conditions, toxic, less yields, complex workups, and environmentally hazardous ingredients. This approach replaces hazardous chemicals with benign material during their design, manufacture, use and disposal. Designing of product is cost-effective and environmentally benign chemically products. It is completely followed to Green Approach. The entire given biologically active compound have shown biological activities such as Antiviral, Anti-HIV, Antibacterial, and Anticonvulsants.

Resumen
AbstractDesign is a decision-making process for which knowledge is a prerequisite. Most decisions are taken at the conceptual stage and have pronounced influence on the final design. The literature, therefore, recommends the incorporation of sustainability criteria, such as environment, at this stage. Difficulty in performing life cycle assessment (LCA) due to low availability of information at the conceptual stage for evaluation and highly abstract nature of solutions, inadequate incorporation of DfE (Design for Environment) guidelines and LCA reports into the design process, and a lack of effective communication of the same to the designers for prompt decision-making are major motivations for the development of a support. This paper discusses a “conceptual Tool for environmentally benign design” – concepTe – that supports designers in decision-making during the conceptual design stage, by offering environmental impact (EI) estimates of abstract solutions with associated uncertainty, for evaluation and selection of the most environmentally benign solution as concept. The EI estimates are calculated by a module in the tool based on a proposed EI estimation method, which requires the support of a knowledge base to fetch appropriate LCA information corresponding to the design element being conceptualized. This knowledge base is grounded in the domain-agnostic SAPPhIRE model ontology, allows semantic operability of the knowledge, and offers the results to the designers in a familiar domain language to aid decision-making. A “proof of concept” of the tool is developed for application in design of building in the AEC (Architectural design, Engineering, and Construction) domain. Further, empirical studies are conducted to evaluate the effectiveness of the “proof of concept” to support decision-making and results are found favorable. The paper also discusses the future scope for further development of the tool into a holistic design decision-making platform.

Resumen
A series of new indole derived mono and bis isoxazole (4a-4f and 5a-5f) was synthesized using highly efficient and environmentally benign ionic liquid containing click synthesis. Anticipated structures of all titled compounds were in agreement with spectral and analytical (C, H and N) analyses. The newly synthesized compounds were screened for their in vitro anticancer activity against MCF-7 and HeLa. The anticancer activity screening results of 5f, 4f and 5a exhibited potent cytotoxic activity against two cancer cell lines with IC50 values nearer to the standard drug doxorubicin. The remaining compounds have shown moderate activity against the tested cell lines.

Resumen
Purpose This paper aims to propose a simple, effective and environmentally benign method for the synthesis of commercially important pigment copper phthalocyanine (PC) blue has been developed using deep eutectic solvent (DES). Design/methodology/approach DES prepared from choline chloride and urea is used as a reaction medium, as well as a source of ammonia. The design of the experiment and factorial design study has proved that the milder reaction conditions with high yields and reusability of DES are the key features of the present study. Findings The synthesized pigment is obtained at milder reaction conditions with excellent yield, which can be seen from the design of experiments done for the optimization of results. Practical implications The synthesized pigment was used as a colorant in epoxy-based paint and in screen ink, which gave satisfactory results with respect to color values and stability. Social implications The screen ink prepared was formulated considering environmental aspects to avoid the use of solvents. Biodegradable components were added to the colorant to make the ink environment friendly. Originality/value Reactions occur at moderate temperatures without affecting the time factor, thus, it saves energy. A simple, effective and environmentally benign method for the synthesis of commercially important copper PC has been developed using DES. After the first batch, DES synthesized can be reused as a reaction medium where only a stoichiometric amount of urea is to be added. Simple work up, high yield and purity are achieved.

Resumen
: The C-Se bond forming reactions are attractive synthetic strategies for biochemists and synthetic chemists alike for the synthesis of various molecules that are of biological, pharmaceutical and material interest. Therefore, the design and synthesis of organoselenium compounds currently constitute engaging fundamental problems in applied chemistry both in pharmaceutical and academic laboratories. This review discusses the recent works reported in carbon–selenium cross-coupling reactions with the emphasis on the mechanistic aspects of the reactions. The reacting species, the addition of ligands, selection of catalysts, use of suitable solvents, proper setting of reaction time, are well discussed to understand the detailed mechanism. Various simple, economical and environmentally friendly protocols are demonstrated, which ensured product stability, low toxicity, environmentally benign and excellent reactivity for the synthesis of organoselenium compounds. This review covers the scientific literature from 2010 to 2019.

Resumen
AbstractThe primary objective of the Consortium for the Molecular Engineering of Dispersant Systems (C-MEDS) was to understand the molecular basis of dispersant systems, the way the components of dispersants act in breaking oil into small drops by studying in detail the processes at the interface of oil and water. As a consequence of such improved understanding, it was also an objective to design alternative concepts in oil dispersion, taking into account natural processes occurring in ocean environments. The development of new environmentally benign dispersants was always an underlying focus of research efforts.

Resumen
Buildingsare found to be an essential part of the needed transition towards energy sustainability. In the past few years, there have been growing interests in net zero energy buildings (NZEB) adapted worldwide. The minimized energy demand and airtightness of a passive house and the low energy buildings have provided in the past a step forward to the energy efficiency goal and the net-zero energy building. Implementation of proven energy efficiency technologies offers the world the fastest, most economical, and most environmentally benign way to alleviate threats. This paper will discuss Net Zero Energy Building definition and design strategies targeting for energy efficiency and environmental sustainability. The literature shows that to improve the integrated performance of the building and to achieve the goal of energy efficient and NZEB, appropriate active and passive design strategies should utilize. Also, energy demand should reduce to a minimum, through energy efficient building designs, leaving only a fraction of the energyrequired to be covered by renewable energy generation.

Resumen
PurposeThe main purpose of this research is to understand the priorities of designers for an ecodesign support, while developing environmentally sustainable products. Also, this study identifies the requirements of the designers for managing the environmental quality of products.Design/methodology/approachThis research is conducted in two phases of survey. In the first phase, various requirements of designers are collected, refined and segregated under certain well defined characteristics of the ecodesign support. In second phase, the designers are asked to rank each characteristic of the ecodesign support in a questionnaire. The responses obtained from the designers are analyzed separately for engineering designers and design researchers by using Henry Garrett ranking technique to identify the priorities of designers for an ecodesign support.FindingsResults show that there is a contrast between the perspective of engineering designers and design researchers, and their priorities for an ecodesign support are opposite to each other. Thus it can be understood that the features which are added by design researchers in ecodesign support may not be adequate for engineering designers to manage the environmental quality of products.Originality/valueThe designers play a key role in the development of environmentally benign products through the use of different ecodesign supports (i.e. tools or methods). Therefore, it is important to understand the desired characteristics of the ecodesign support from designer's perspective. Also, the priorities of designers from academia (design researchers) and industry (engineering designers) must be understood because they are the two stakeholders indulged in the development and usage of various ecodesign supports for environmentally conscious product development (ECPD).

Resumen
Safety concerns about organic media-based batteries are the key public arguments against their widespread usage. Aqueous batteries (ABs), based on water which is environmentally benign, provide a promising alternative for safe, cost-effective, and scalable energy storage, with high power density and tolerance against mishandling. Research interests and achievements in ABs have surged globally in the past 5 years. However, their large-scale application is plagued by the limited output voltage and inadequate energy density. We present the challenges in AB fundamental research, focusing on the design of advanced materials and practical applications of whole devices. Potential interactions of the challenges in different AB systems are established. A critical appraisal of recent advances in ABs is presented for addressing the key issues, with special emphasis on the connection between advanced materials and emerging electrochemistry. Last, we provide a roadmap starting with material design and ending with the commercialization of next-generation reliable ABs.

Resumen
AbstractAmino-functionalized Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2–NH2 NPs) were prepared by treating Fe3O4@SiO2 NPs with (3-aminopropyl)-triethoxysilane. They have been characterized by powder X-ray diffraction, vibrating sample magnetometer, scanning electronic microscopy, energy dispersive X-ray, thermogravimetric analysis and FT-IR spectroscopy. A neat, atom-economical, environmentally benign one-pot multicomponent synthetic route for the synthesis of furo[3,2-c]coumarins in good yields has been devised using the Fe3O4@SiO2–NH2 NPs. The present methodology can be used for the design of libraries and diversity-oriented synthesis, and has potential for biological applications and drug discovery.

Resumen
The concept of single-site heterogeneous catalysis, herein defined and extensively illustrated, offers a strategy for the design of new solid catalysts. By capitalizing on the opportunities presented by nanoporous materials to assemble a wide range of new, well-defined, catalytically active centres, it is possible to bring about numerous environmentally benign processes that can replace traditional methods of chemical production. The latter often employs aggressive, corrosive or hazardous reagents. By using both microporous (less than 20 Å diameter) and mesoporous solids (20–500 Å diameter), abundant scope exists for the construction and application of shape-selective, regio-selective and enantioselective catalysts.

Resumen
Two-dimensional peptide and protein assemblies have been the focus of increased scientific research as they display significant potential for the creation of functional nanomaterials. Soluble subunits derived from a variety of protein motifs have been demonstrated to self-assemble into structurally defined nanosheets under environmentally benign conditions in which the components often retain their native structure and function. These types of two-dimensional assemblies may have an advantage for nanofabrication in that their extended planar shapes can be more straightforwardly incorporated into the current formats of nanoscale devices. However, significant challenges remain in the fabrication of these materials, particularly in devising methods to control the size, shape and internal structure of the resultant materials. Geometrical frustration may be envisioned as a possible mechanism to exert control over these structural parameters through rational design. While this objective has yet to be realized in practice, we discuss in this article the potential role of geometrical frustration as a principle to rationalize unusual self-assembly behaviour in several examples of two-dimensional peptide assemblies.
