Zinc Oxide Research Paper

1308 Words6 Pages

2. Zinc Oxide Zinc oxide is a white colored inorganic compound which is insoluble in water but is highly soluble in acid or alkaline solutions. It does not occur naturally instead, it is created when zinc is chemically heated and combined with oxygen molecules. There are two possible structural forms of zinc oxide: hexagonal and cubic. Hexagonal crystals are commonly found in nature. With the advent of nanotechnology, nano-engineered Zinc oxide is commercially used in various cosmetic products because it has good transparency and refractive index properties. Nano formulated zinc oxide is estimated to have a worldwide production of 550 tons per year, and a substantial percentage is found in cosmetics comprising about 70% primarily because of its higher solubility in comparison with its bulk version (Hillegass J.M …show more content…

Surface area is an important physical parameter which determines the extent of developed toxicity. Notably, the particular the size of the nanoparticle is directly correlated to its particle surface area (Ho, Meng et al.,2011). With the reduction in the size of nano zinc oxide, there is an increase in the surface area and this directly impacts the nanotoxicological behavior of the nanoparticle. iv. Concentration-dependent toxicity Various experimental studies have established the concentration-response relationships of zinc oxide nanoparticles. ZnO Nanoparticles pose limited risk to consumers when they are present at a 25% concentration.However, an increase in the concentration of nanoparticles present in cosmetics proves to be highly dangerous. Few studies have shown concentration-dependent genotoxic effects of ZnO nanoparticles in human lymphocytes. Additionally, significant changes were detected in the systemic response post inhalation of concentration-dependent zinc oxide nanoparticles (Monsé C, et al.,2018). v. Particle coating-dependent

This layer is virtually invisible as it has a very small thickness and is also transparent. In order to prevent the fogging and dirt on glasses, the coating must be under UV illumination for it to sustain the hydrophobic property. 3.2.2 Methods to fabricate TiO2-SWCNT composite There are enormous methods available to prepare the nanocomposite of CNT and TiO2 which are sol-gel method, electrospinning method, hydrothermal and more. 3.2.2.1 Sol-gel synthesis Sol-gel is a method in which small molecules are used to produce solid materials. The method is used for the fabrication of metal oxides.

Sludge Lab Report

615 Words | 3 Pages

Based on our initial observations(appearance) of solid #4 and the fact that they are not soluble in water and will sink, my partner and I have concluded that solid #4 are small pebbles. Solid #2 are small pieces of tin foil. We believe this because solid #2 isn’t soluble in water and doesn’t float just like tin foil. We also think this because of our initial observations(appearance). Nika and I believe that solid #6 is dried up purple food coloring because once you put the solid in water it dissolves and the water becomes purple(just like the color of our sludge).

It is more important to give a special kind of attention to the corrosion behavior differences of the coatings, to ensure that the new coating is an acceptable as alternative. For instance, recently many zinc-nickel alloys have been utilized for replacing cadmium layers but due to their difference in corrosion behavior, various issues arise. Zinc-nickel alloys exhibit confined corrosion and cracking, whereas cadmium layers are susceptible to uniform corrosion. Anyhow the dissimilarities in corrosion behavior will play a vital role when providing the necessary corrosion protection

Some of those toxins are known endocrine disrupters, which may negatively impact the reproductive systems of the wildlife that ingest the contaminated microplastics, or the reproductive systems of their predators. In December of 2015, the United States House of Representatives passed the Microbead Free Waters Act, authored by Rep. Frank Pallone (New Jersey-Democrat) and Rep. Fred Upton (Michigan-Republican). Should this piece of legislation pass the senate, it will phase out the production of personal care products with microbeads manufactured and sold by American companies no later than July 1, 2017. * Some states such as Illinois and Colorado have already passed legislation that phases out the sale of these products, and some companies, such as Unilever, have voluntarily agreed to stop manufacturing hygiene and beauty products with microbeads because of these environmental concerns.

The awareness of the inclusion of zinc in the management of childhood diarrhea among health care providers has been reported to be high in some developing countries. The use of zinc to treat diarrhea has the potential to avert up to an estimated 400,000 deaths annually and has been recommended for treatment of children with diarrhea in developing countries by UNICEF and WHO. A major concern is that ORT does not affect morbidity. Zinc has been found to reduce the duration and severity of diarrhea episodes and to lower incidence for the next two to three months [10]. WHO identified a number of management practices and these are breast feeding, Oral Rehydration Therapy (ORT) and weaning practices.
