Nanotechnology Phenomena in the Light of the Solar Energy

Abstract

Nowadays, nanotechnology is one of the most conducting research-based areas because it merges understanding from many disciplines such as Physics, Chemistry, Biology, Medicine, Engineering, and Environmental Sciences among others. There are no limits to the potential applications of nanotechnology. It is helping to considerably improve, even revolutionize, many technology and industry sectors. New nano-and bio-materials, and nano-devices, are produced and monitored through nanotechnology instruments and manners, which explore and transform the features, responses, and functions of living and non-living matter, at sizes below 100 nm. This review focuses on nanotechnology, its definition and applications, and sunlight as a driving tool for developing nanotechnology. Sunlight as a free source of energy and clean agent for several physical and chemical reactions constitutes an increasing interest for both science and technology. Nanotechnology should focus on more using sunlight as a free energy source and an environmentally-friendly agent for its advancing for the human kind best future.

Removing Antibiotic-Resistant Bacteria (ARB) Carrying Genes (ARGs): Challenges and Future Trends

“…They also focused on the pathway of the influences of diverse disinfection techniques in water and wastewater (chlorination, UV irradiation, Fenton reaction, ozonation, and photocatalytic oxidation) (Figure 4). They also discussed the impacts of constructed wetlands (CWs) and nanotechnology [80] on ARB and ARG ( Figure 5).…”

Water Reuse: Emerging Contaminants Elimination—Progress and Trends

“…Chemicals like chlorine, hydrogen peroxide, ozone as well as the integration of these oxidants involving transition metals and metal oxides based catalysts in the so-called AOPs are needed for eliminating ECs from wastewater [92] [93]. Moreover, an energy source like UV-vis radiation, electric current, solar [94], gamma-radiation, and ultrasound are also utilized [95] [96]. In AOPs, oxidizing ECs is founded on generating free radicals, especially, hydroxyl radicals that ease the transformation of contaminants to less poisonous and more de- [1].…”

Direct Potable Reuse: The Singapore NEWater Project as a Role Model

“…Electrochemistry is more and more viewed as a central knowledge for expanding a possible society from fuel cells to waste electrochemical oxidation, desalination, and water reuse [42] [43] [44]. Electrochemical AOPs are magnetizing many of the awareness, thanks to their numerous benefits, comprising employing a more hygienic reagent (electricity), potential to attain outstanding levels of mineralization, versatility, elevated energy effectiveness [45], amenability of automation and safety [46] [47] [48] [49]. As shown in Table 1, electro-Fenton is fast rising as the most encouraging between electrochemical techniques [50] [51], particularly via the integration with nanomaterials like graphene [52] [53] or boron-doped diamond (BDD) to boost anodic oxidation as an extra source of • OH [3] [54].…”
