Sustainable development, the design of green and economically feasible processes to produce synthetic polymers is one of the major needs and biggest challenges. Catalysis of polymerization processes is among the most important applications within the field of nanoscience. Intensive research is being conducted and considerable success has been achieved in the heterogenization of various homogeneous catalysts on nano supports for polymerization of olefins and dienes. The large surface area of various nanomaterials qualifies them quite naturally to act either as a heterogeneous promoter for catalytic reactions or as a support for the heterogenization of homogeneous catalysts. To the polymerization of olefins and dienes by using nanocatalysts are devoted significant numbers of published papers, but to elucidate the possible effect of both the type and properties of nano supports and their sizes and amounts on the activity and stereoselectivity of heterogenized catalysts and the properties of the obtained polymers are needed more detailed studies. This review attempted to collect some published research materials in the field of the nanocatalysis of olefins and dienes polymerization processes and our main aim is to assess the critical points and to indicate the future perspectives and possible strategies in this area of research. We are confident that this review will be a helpful companion and deliver key hints to those, in academia and in the industry, who decide to move their research interest in this direction

Contemporary Context

In searching for answers about the actual relation between two apparently incompatible concepts: the Kingdom of God and the Sustainable Development (SD), we will try to put them side by side and use respective comparative findings, in order to see if they can work together and possibly benefit from each other. The aim is to better understand future perspectives that are opening for the church within the contemporary context. The two concepts considered in this research, the Kingdom of God and SD, are never supposed to be separated. Although coming from different sources, using different languages, and springing out from different socio-political contexts, they tackle the same set of universal issues; both are eagerly anticipated, their fulfilment is of utmost importance, they both call for profound personal and communal transformation, both are powerfully creative and innovative, and both have the capacity to mobilize communities, peoples, and resources. The intersections between the SD and the Kingdom of God create opportunities for the church to practice shalom and to nurture hesed in the world by encouraging inclusiveness, lobbing for social justice, carrying for the poor and marginalized, and extending love and compassion onto the whole of creation, without losing its genuine identity. Within the SD framework, the role of the church is to make sure that nobody is left behind. The church might be the best part of the SD practice by persistently insisting on the same universal set of Kingdom values no matter how circumstances are changing.

Halloysite nanotubes (HNTs), clay minerals belonging to the kaolin groups, are emerging nanomaterials which have attracted the attention of the scientific community due to their interesting features, such as low-cost, availability and biocompatibility. In addition, their large surface area and tubular structure have led to HNTs’ application in different industrial purposes. This review reports a comprehensive overview of the historical background of HNT utilization in the last 20 years. In particular it will focus on the functionalization of the surfaces, both supramolecular and covalent, following applications in several fields, including biomedicine, environmental science and catalysis.

Development Alternatives

The increased availability of reliable and efficient energy services stimulates new development alternatives. This article discusses the potential for such integrated systems in the stationary and portable power market in response to the critical need for a cleaner energy technology. Anticipated patterns of future energy use and consequent environmental impacts (acid precipitation, ozone depletion and the greenhouse effect or global warming) are comprehensively discussed in this chapter. Throughout the theme several issues relating to renewable energies, environment, and sustainable development are examined from both current and future perspectives. It is concluded that green energies like wind, solar, ground-source heat pumps, and biomass must be promoted, implemented, and demonstrated from the economic and/or environmental point view.

Exact Figure

Industry deals with vast quantities of materials, many of which are in a finely divided state and can give rise to dust problems. If we include in our industrial group the large fuel-burning complexes, such as power stations and refineries, we find that nearly a million tons of fine dust is discharged annually into the atmosphere over Britain, as well as over 6 million tons of sulphur dioxide. A good deal of intensive research has been undertaken to investigate the problems of control of the inevitable emissions, and considerable success has been achieved. While it is difficult to give an exact figure for the amount of dust recovered because of the wide variation in the standards adopted by the different industries, it is probable that over 98% of the dust produced by industry is extracted from the effluent gases before discharge.

2D Nanomaterials

AbstractThe development of two-dimensional (2D) monoelemental nanomaterials (Xenes) for biomedical applications has generated intensive interest over these years. In this paper, the biomedical applications using Xene-based 2D nanomaterials formed by group VA (e.g., BP, As, Sb, Bi) and VIA (e.g., Se, Te) are elaborated. These 2D Xene-based theranostic nanoplatforms confer some advantages over conventional nanoparticle-based systems, including better photothermal conversion, excellent electrical conductivity, and large surface area. Their versatile and remarkable features allow their implementation for bioimaging and theranostic purposes. This concise review is focused on the current developments in 2D Xenes formed by Group VA and VIA, covering the synthetic methods and various biomedical applications. Lastly, the challenges and future perspectives of 2D Xenes are provided to help us better exploit their excellent performance and use them in practice.
