“…Debido a las características de las tecnologías emergentes o convergentes, y a pesar de las dificultades metodológicas que implica, estas se han estudiado como sectores de innovación, pues son tecnologías de uso transversal en diversos sectores productivos, como el farmacéutico, el de alimentos, el agrícola, el medio ambiente, la manufactura, entre otros (Amaro y Morales, 2016;Castañeda, León, Castañeda et al, 2017;Foladori et al, 2017).…”

ResumenLas tecnologías emergentes han sido comúnmente analizadas desde la perspectiva teórica de los sistemas de innovación. Esto ha significado partir de la premisa de que el desarrollo, uso, difusión y explotación de la tecnología son comportamientos similares a los que exhibe cualquier otro sector económico tradicional. Pero esto omite el hecho de que las tecnologías emergentes tienen particularidades que van desde las características de los actores involucrados, los derechos de propiedad, las dinámicas sociales, tecnológicas, económicas e institucionales en las que se ven insertas, hasta la propia definición metodológica del objeto de estudio. Lo anterior sin obviar las dificultades de acceso y categorización de la información, dado que en todos los casos que aquí se tratan, las tecnologías emergentes son transversales a muy distintos sectores económicos y, por tanto, su uso y aplicación se diversifica en diferentes procesos, productos y servicios. Este artículo tiene por objetivo presentar una reflexión acerca de las posibles alternativas metodológicas no exhaustivas para el estudio de las tecnologías emergentes o convergentes, Marcela Amaro Rosales, Eduardo Robles Belmont como la biotecnología, la nanotecnología, las tecnologías de la información y la genómica, entre otras, así como discutir la pertinencia de usar el marco de análisis de los sistemas de innovación, sin que esto signifique desechar su aplicación, sino más bien establecer esquemas complementarios que nos ayuden a tener una mejor comprensión de la dinámica y evolución de dichas tecnologías. Palabras claveInnovación, tecnologías emergentes, convergencia tecnológica, indicadores de ciencia y tecnología AbstractEmerging technologies have been analyzed from the innovation systems theoretical approach. This has meant starting from the premise that the development, use, dissemination and exploitation of technology are similar behaviors that exhibit any other traditional economic sector. However, this omits the fact that emerging technologies have particularities that range from the characteristics of the parties involved, the property rights, the social, technological and institutional dynamics in which they are involved; even the methodological definition of the object of study. This without forgetting the difficulties of access and categorization of information, as in all cases discussed here, emerging technologies cut across many different economic sectors and therefore its use and application diversifies into different process, products and services. This article aims to present a reflection on the possible non-exhaustive methodological alternatives for the study of emerging and/or convergent technologies, such as biotechnology, nanotechnology, information technologies and genomics, among others, as well as to discuss the relevance of using the framework for the analysis of innovation systems. Without this means discarding its application, but rather establishing complementary schemes that help us have a better understanding of the dynamics and ...

“…Besides, their qualities have uses in physics, chemistry, engineering and materials, medicine, biology, agriculture and computer science (Meyer & Persson, 1998;Mehta, 2002). However, it is to environmental applications, such as the treatment of drinking water or the filtration of contaminants from hot gasses, that the physical and chemical properties have most successfully been applied and commercialized to date, which can also be applied to Latin America (Castañeda Olvera et al, 2017).…”

Nanotechnology innovation has peculiar characteristics. This paper reviews the methodology and results, drawn from cases analyzed on two EU projects: EULASUR and EULACERMAT. The cases covers both European and Latin American experiences, particularly from Mercosur countries. We analyze specifically nanotechnology innovation based on new and advanced materials. The main conclusion of this paper is that innovation in advanced materials, based on nanotechnology, relies crucially on networks of cooperative agents. It starts from the validated assumption that innovation is interactive in nature. Therefore, it is needed to co-create through the participation to obtain feasible results. The position of advanced materials within the related (new or existent) value chains explains to a great extend the border conditions for innovating in this nanotechnology field. It appeared clearly that innovation in this field is a complex problem, with the same degree as researching (nanoscience), and that the connections between them were not obvious nor simple.

“…Clean and safe water is a basic asset for a flourishing society as well as a thriving economy [ 2 ]. Unfortunately, a rapid increase in population, expanding industrialization, urbanization and extensive agriculture practices are causing continuous deterioration of quality water resources, which is a serious matter of global concern [ 3 , 4 , 5 ]. Worldwide, around 1.2 billion populations do not have access to safe drinking water, 2.6 billion people struggle to fulfil basic sanitation, millions of people, particularly children, have lost their lives from diseases communicated through unsafe and polluted water [ 6 , 7 ].…”

Nanotechnology in Wastewater Management: A New Paradigm Towards Wastewater Treatment

Clean and safe water is a fundamental human need for multi-faceted development of society and a thriving economy. Brisk rises in populations, expanding industrialization, urbanization and extensive agriculture practices have resulted in the generation of wastewater which have not only made the water dirty or polluted, but also deadly. Millions of people die every year due to diseases communicated through consumption of water contaminated by deleterious pathogens. Although various methods for wastewater treatment have been explored in the last few decades but their use is restrained by many limitations including use of chemicals, formation of disinfection by-products (DBPs), time consumption and expensiveness. Nanotechnology, manipulation of matter at a molecular or an atomic level to craft new structures, devices and systems having superior electronic, optical, magnetic, conductive and mechanical properties, is emerging as a promising technology, which has demonstrated remarkable feats in various fields including wastewater treatment. Nanomaterials encompass a high surface to volume ratio, a high sensitivity and reactivity, a high adsorption capacity, and ease of functionalization which makes them suitable for application in wastewater treatment. In this article we have reviewed the techniques being developed for wastewater treatment using nanotechnology based on adsorption and biosorption, nanofiltration, photocatalysis, disinfection and sensing technology. Furthermore, this review also highlights the fate of the nanomaterials in wastewater treatment as well as risks associated with their use.
