Nanomaterials

body focuses on strengthening our brain. IBM hopes to re-engineer the brain by 2030, and with Howard Hughes Medical Institute’s efforts to capture thought at moment of creation, forward-thinkers believe we can one day replace all our neurons with nanomaterials that process thoughts at supercomputer speeds. Futurists see our powerful new 2040 body as the next step in human evolution; and many believe that this miracle will become reality in time to benefit many alive today. Living in an amazing…

“Nanotechnology is pushing materials science beyond the limits of what once seemed impossible. When combined with ultra-high-strength concrete, nanomaterials such as Carbon Nanotubes (CNTs) create a material so strong in both tension and compression that steel rebar is no longer needed in construction, therefore expediting the building process” ( Alex Garkavenko, par.6). Basically, Alex states that…

4. Discussion ZnO NPs are known to be cytotoxic and genotoxic in vitro and in vivo [9; 24-26]. However there is a lack of information where immunomodulatory effects of ZnO NPs are considered. Since, in vitro system cannot mimic the complexity of an in vivo system; hence in vivo is preferred for the toxicological evaluation. In the present study BALB/c mice were chosen as the in vivo model due to their immunocompetence and similarity with human metabolic activity, biochemical and physiological…

In this study, we use the modified organo nanoclay as a new sorbent for separation and preconcentration trace amounts of Au(III) in aqueous solutions. Nanoclay was modified with 5-(4'-dimethylamino benzyliden)-rhodanine. Modified nanoclay was used as a solid sorbent for separation and preconcentration trace amounts of Au(III) ions. The sorption of gold ions was quantitative in pH range of 2.0 to 6.0, whereas quantitative desorption occurs instantaneously with 6.0 mL of 1.0 mol L-1 Na2S2O3. The…

this, large numbers of products containing NPs are commercially available, including sunscreens, cosmetics, foods, fertilizers and medical equipment. (50) Zinc oxide nanoparticles (ZnO NPs) are known to be one of the most important metal oxide nanomaterials…

The industrial revolution was the transition from hand production methods to machine. This revolution, which happened at the 19th century in the Great Britain, has affected every single aspect of peoples’ everyday lives directly or indirectly. The industrial revolution promotes industrialization and it led to the creation of factories. The creation of factory, which was promoted by industrial revolution, improved the manufacturing process, and the improvements means that production was increased…

Fish have a unique position with respect to their taxonomic and phylogenic status among vertebrates and occupy an important place in vertebrate’s genealogy. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary (1 – 2 ºC) as ambient temperatures change. Majority of siluroid fish are economically important for human consumption. Protein and vitamins content in fish flesh varies from high to moderate and make it as rich source of protein diet. Fishes of siluroid…

This method consists of transplanting in humans islets of Langerhars from genetically modified pigs. To do so, the entrepreneurs decided to build a large and complex ecosystem, involving biotechnology startups, nanomaterials startups, R&D labs, venture capitalists, governmental agencies, policy makers and pharmaceutical companies. The venture faced the challenge of taking important decisions about the following areas: genetic manipulation of pigs; materials associated…

CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…
