  • Nanotechnology During The 1900s

    1134 Words  | 5 Pages

    Throughout the 1900s, there were new ideas that were both accepted and rejected as useful and realistic. Nanotechnology, radio, and plastic were all developed during this time period and were presented in different ways. The ways in which these new technologies are presented and imagined greatly effects its future. The timing of innovations, the speed of its upheaval, its usefulness in society, and economic impacts are critical factors in the development of technologies. On the other hand, the development of wooden airplanes was not as successful because of the process in which this advancement was researched and applied.

    In the article “Medical Technology and Ethical Issues” by William E. Thompson and Joseph V. Hickey give the pros and cons of medical technology deciding patient outcomes instead of a doctors instincts. Critics and ethicists are against the RIP system. According to the authors, the program makes informed decisions about life saving treatments. “In emergency rooms across the world, this program is helping doctors make life–saving treatments or simply allow patients to die. Using statistical probability, the program analyzes all of the input on a particular patient and makes a prognosis on the likely hood of survival”.

    Scientists can create new organisms with the desired characteristics by modifying the DNA of the organism using genetic engineering. New forms of life that cannot be derived from artificial intelligence are being developed and there are concerns about the risk of their introduction into the environment. Nanotechnology is another area of scientific discovery that has attracted a lot of attention recently. Thanks to the discovery of new materials and manufacturing methods, researchers were able to produce materials and devices on a scale previously thought to be impossible, which they considered impossible. This has led to new developments in various industries, such as health, energy and electronics, but has also raised concerns about the dangers of nanotechnology.

    Food production has been a matter that has been disputed for years now because of the things that have been added to crops. While pesticide helps keep other organisms from taking crop harvest, it has also added chemicals into the food that we consume; chemicals that should not be inside of us. Genetic engineering would allow for the natural modification of food to provide DNA genes that can be used to act as a shield against pests and diseases. With the DNA modification of crops, there would be no need to

    In a typical procedure, TiO2 nanoparticles (TNP, 3.6 g) with pure anatase was added into a NaOH (10 N, 150 mL) solution in a teflon lined stainless steel autoclave, sonicated (2 min) and heated the autoclave at 403 K for 48 h in an oil bath under autogenesis pressure with stirring (250 rpm). After 48 h, the autoclave was cooled down to room temperature, subsequently the formed nanotube was washed with ultrapure water until the pH of the solution was >7. Afterward the nanotubes were washed with HCl (0.1 M) solution for overnight under stirring at room temperature. Then the nanotubes were filtered (Millipore filtration assembly) under vacuum pump and repeatedly washed with ultrapure water until the filtrate was free from chloride ion, which was checked by the addition of silver nitrate to the filtrate. Finally, the obtained nanotubes were dried in an oven at 343 K for 12 h and calcined in a muffle furnace at 773 K for 4 h.

    EXPERIMENT Polyol process is used for the synthesis of the nanoparticles. A polyol is an alcohol containing multiple hydroxyl groups. This process involves hydrolysis and inorganic polymerization carried out on the salts dissolved in a polyol medium. The polyol acts as a solvent for the precursor salts because of its high relative permittivity, and allows one to carry out hydrolysis reactions under atmospheric pressure in a large temperature range up to the boiling point of the polyol. Ethylene glycol has been widely used in the polyol process for the synthesis of metal (pure and alloyed) nanoparticles due to its strong reducing power and relatively high boiling point (~1970C).

    Evolving methodologies for curriculum and instruction are essential to improving how we educate. McMillian positions that essential to this is understanding the value of scientific inquiry. He explains, “the principles of scientific inquiry provide the foundation for conducting studies…analyzing educational problems, making decisions, and designing, conducting, reporting, and evaluating” (McMillian, 2016, p. 7) to provide significant benefits for engaging students and affecting achievement. Among the changing methodologies is the consensus that the use of STEM-education concepts are necessary to prepare students for 21st century skill-building. Subsequently, this has led to an instructional methodology that highlights math-centered curriculum, and the instruction of science and technology as independent of core content.
