Abstract:
As per today, ~55% of the world’s population lives in urban areas. It is projected that it would reach ~2.5 billion by 2050, with ~90% of this increase in Asia & Africa. With such an upsurge of urban population and climate change increase of the average seasonal atmospheric temperature, several SDGs challenges will have to be overwhelmed. In this regard, STI and R&D are a potential bridge in addressing such challenges within the energy, water & health nexus. In the energy sector, Vanadium based thermochromic nano-coatings are ideal for smart windows applications regulating solar heat radiations with zero energy-input (Green air-conditioning) [1]. Likewise, nano-fluids as a new generation of superior coolants would play a major role in waste heat recovery as well as drug delivery[2-4]. In addition, it was recently validated that CO2 can be used to bioengineer several multifunctional carbonates. These latter exhibited effective fertilizing response, and, a high reflective properties equivalent of radiative cooling paint as well as a significant porosity/hardness as a potential Supplementary Compound Material (SCM) for cement industry [5].
This contribution is intended to highlight on the above-mentioned properties in line with UN-SDGs vision & mission.
