The state of the art of nanomaterials and its applications in energy saving

Abstract Background Nanomaterials have emerged as a fascinating class of materials in high demand for variety practical applications. They are classified based on their composition, dimensions, or morphology. For the synthesis nanomaterials, two approaches used: top-down and bottom-up approaches. Main body abstract Nanoscale structures potential to be used production newly developed devices with efficiency, low cost, energy There several contributions renewable conversion storage sector, such solar photovoltaic systems, fuel cells, thermal lithium-ion batteries, lighting. Furthermore, nanofluid-based collectors new generation use nanotechnology. It has increase collector efficiency by up 30%. Short conclusion Graphene graphene derivatives known more efficient energy-saving materials, ability maximize heat transfer save 30% water desalination. Silver nanoparticles (Ag NPs) powerful antibacterial material that can kill wide microorganisms. commonly treatment incorporated into polyethersulfone (PES) microfiltration membranes. The an Ag-PES membrane improved antibiofouling performance PES From industrial application nanotechnology, applications TiO 2 -based nanocoatings dust-repellent coatings panels improve reduce amount required maintenance. nanoscale dimension these particles facilitates movement various parts, resulting serious diseases cancer organ damage. As result, it is suggested focus our incoming research disposal nanomaterial waste safe application.
