Abstract:-
Nanotechnology increases the strengths of many materials and devices, as well as enhances efficiencies of monitoring devices, remediation of environmental pollution, and renewable energy production. While these are considered to be the positive effect of nanotechnology, there are certain negative impacts of nanotechnology on environment in many ways, such as increased toxicological pollution on the environment due to the uncertain shape, size, and chemical compositions of some of the nanotechnology products (or nanomaterials). It can be vital to understand the risks of using nanomaterials, and cost …show more content…

Social scientists have suggested that nanotechnology's social issues should be understood and assessed not simply as "downstream" risks or impacts. Rather, the challenges should be factored into "upstream" research and decision-making in order to ensure technology development that meets social objectives Many social scientists and organizations in civil society suggest that technology assessment and governance should also involve public participation Over 800 nano-related patents were granted in 2003, with numbers increasing to nearly 19,000 internationally by 2012. Corporations are already taking out broad-ranging patents on nanoscale discoveries and inventions. For example, two corporations, NEC and IBM, hold the basic patents on carbon nanotubes, one of the current cornerstones of nanotechnology. Carbon nanotubes have a wide range of uses, and look set to become crucial to several industries from electronics and computers, to strengthened materials to drug delivery and diagnostics. Carbon nanotubes are poised to become a major traded commodity with the potential to replace major conventional raw materials. Nanotechnologies may provide new solutions for the millions of people in developing countries who lack access to basic services, such as safe water, reliable …show more content…

    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.

An atom has a complex structure, and the knowledge we have of it has changed many times throughout history. This tiny maze of parts has helped us learn important ideas about the structure and study of microscopic particles(O.I).

The first phase will possibly work since the majority of citizen want to control. The 21st century has many methods to be heard either through petitions or social medias. Now, the United State Patent Office can receive better information from scientists and technologists to make better patent laws. The first phase is the easiest out of the two.

    Next, we turned our attention to the effect of oxidants. When various oxidants such as TBHP, K2S2O8, and DDQ were scrutinized (Table 1, entry 13-15), and TBHP (1 equiv) had the beneficial effect to give the best yield (Table 1, 75%; entry 13). However, the yield lowered when the amount of TBHP was decreased. The reaction did not proceed at all in the presence of other nano-particles, such as ZrO2, Fe3O4, NiO and in some copper salts CuBr2, CuCl2, (Table 1, entries

    This technological advancement is believed to be able to address the knowledge gap in neurophysiology and neurological disorder. Nanosystems on a chip, is said to be able to provide critical foundation to diagnostics biomarkers and point-of-care technologies as well as detection of pathogen. These advances, though not consistently available, are however thought to have huge potential in transforming healthcare sciences Rocco, M. C. (2011). Pharmacogenomics/genome sequencing is seen as another possible advancement and with pharmacogenomics; tools are still being industrialized for the bigger data examination which will help with the purpose of population healthcare. ’’

First, the technology showed inaccurate blood test results that some patients were revisited for traditional method. Because it was cheaper and faster, the patients were sent back to Theranos partnered centers for blood tests (2).

    Organizations that produce normal products greatest responsibility is to themselves, organization such as Apple and Samsung seek to protect their intellectual property so that they can make a profit on the products they spent resources making (Kubasek et al., 2016). These two organizations fight has gone as high as the Supreme Court, who in turn sent it back down to the lower courts without really resolving anything (Goel, 2016). This all seems rather frivolous when it is compared to patents in the medical industry. These companies are working to make life saving products, a very noble cause.

    Despite our advances in medical technology, each year, thousands of people suffer and die due to organ failure. There are various causes to organ failure, either by physical damage, genetic mutation (exogenous factors: e.g. sunlight, radiation, smoking, etc..), and genetically inherited diseases. At this point in time, there are numerous of ways to solving organ failure, such as through the use of dialysis, pacemakers, drugs, etc… But in the end, the most sustainable way of potentially curing organ dysfunction is through organ transplants. Those who have passed away due to organ failure did not die because of the lack sufficient medical treatment, in fact the success rates of organ transplants operated around the world are all over 80%, so
