The society of the 21st century is travelling to an impressive age of development and innovation. It is characterized by the implementation of new technologies that will possibly modify the way of life like IT and the electronic revolution have. It is hoped that the advances from nanoscience and nanotechnology, specifically in the development of new processes and materials at a nano scale level, draw a map for a route towards potential solutions to the problems regarding energy, environment, health, food, etc. These areas require urgent attention in order to improve the quality of life for the present and future generations.
These scenarios raise the need to socialize this new knowledge, to propose and access ways to the interested community and to the new generations who are formed inside this transition. One of the ways to do this is precisely magazines for the general population, which without losing the rigor and precision will accompany the readers who are interested in this fascinating journey in nanoscience and nanotechnology.
This publication is orientated to explore the extraordinary universe of the nanometric scale with dedicated sections to the advances, perspectives, achievements, social and economic impact, intellectual prosperity, education, regulation and social responsibility among others. The magazine will have international coverage, with the desire that it contributes to the task of strengthening the network of the knowledge in nanoscience and nanotechnology, as well as stimulate the new generations to assume the challenges imposed by science and technology of the present century. We hope that the magazine accompanies other initiatives of this nature, and could prosper with the principal aim of socialisation and promotion of the nano, a new dimension of knowledge.
The global water crisis is one of the most important challenges facing
the society in the 21st century. By pollution, lack of proper management
and population growth, the availability of this valuable natural
resource is committed. In some countries, the average gradual loss per
capita availability of water has already reached alarming levels, which
makes it necessary the urgent search of sustainable and effective solutions.
One of the goals incluided in the 2030 Agenda for Sustainable Development
formulated by the United Nations, stablished the need to: “ensure
availability and sustaninable management of water and sanitation for all”
with the commitment to achieve it by 2030, “universal and equitable access
to safe and affordable drinking water for all, improve water quality
by reducing pollution, eliminating dumping and minimizing release of
hazardous chemicals and materials, halving the proportion of untreated
wastewater and substantially increasing recycling and safe reuse globally,
expand international cooperation and capacity-building support
to developing countries in water- and sanitation-related activities and
programmes, including water harvesting, desalination, water efficiency,
wastewater treatment, recycling and reuse technologies”, among other
In order to achieve the Agenda goals, specifically those related with water
sanitation, bio and nanotechnology can contribute effectively through
its capabilities for detection, mitigation and remediation actions. New
environmentally friendly materials and their exceptional properties,
can contribute to the design and configuration of sensors for monitoring
and measurement as well as bio-nanostructured membranes and nanoparticles
for selective removal of contaminants -such as heavy metals-.
In addition, these technologies can help with replacement of beneficiation
methods and practices responsible for contamination of water for
This issue of the journal Nano is devoted to what nanotechnology can
offer in terms of efficient solutions to recover one of the world’s most
precious and necessary natural resources “WATER”.
