FREMONT, CA: Nanomaterials demonstrate unexpected properties relative to their bulk counterparts; their high surface-to-volume ratio confers special physicochemical properties, including flexible functionality and improved reactivity or selectivity.
From saving raw materials, energy and water, to minimizing greenhouse gasses and hazardous waste, nanotechnology's unique features will be seen in a range of goods, processes, and applications that will undoubtedly encourage environmental and climate conservation.
Environmental protection is one of the most significant issues facing the human race. Over the years, people have unwittingly devastated their surroundings by making and discarding plastics, leading to climate change by mining and consuming fossil fuels and polluting the air and water with human-made creations. But now is the time to repair the ecosystem and the relationship with it, with nanotechnology poised to play a vital role in ensuring the world's future survival.
Nanotechnology-based technologies can contribute to the long-term efficiency, availability, and viability of water in a variety of ways:
Treatment and Remediation
Nanotechnology could produce a new generation of nanomembranes for separation to allow for greater purification and desalination of water and improved means of eliminating, reducing, or neutralizing water pollutants. The latter might encompass zeolites, carbon nanotubes, Self-Assembled Monolayer on Mesoporous Supports (SAMMS), single-enzyme nanoparticles, and biopolymers, to name a few.
Sensing and Detection
New and upgraded sensors capable of detecting chemical and biological contaminants at low concentrations can be accomplished with nanotechnology. Nanomaterials also facilitate the use of photoelectrochemical analysis, the incorporation of light reaction and chemical sensing for biological and chemical monitoring, and the negation of the need for costly and specialized tools and operations.
This concerns not only 'traditional' pollutants but also waterborne infectious diseases. For example, nanotechnologies may provide alternative chlorine-free biocides in silver and titanium dioxide catalysts for photocatalytic disinfection.
Practical water-cleaning applications currently in use require the use of iron nanoparticles to extract organic solvents in groundwater. Nanoparticles spread by water and decompose solvents without draining water out of the surface, making the process more robust and inexpensive. Nanotechnology-based solutions can also eliminate hazardous waste. Titanate nanofibers serve as strong absorbents for the removal of radioactive ions like cesium and iodine from water.
