3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…

Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

The diffraction pattern was scanned over 2 range of 3 to 50o at a scanning rate of 1o/min. The relative degree of crystallinity (RDC) was calculated to determine the degree of drug crystallinity in formulation compared to pure drug, by using the following equation18. (Maulvi et al., 2011) EXM…

5. Proposed Research Questions and Tasks Four proposed research tasks will direct to fabrication conditions (Task 1), fabrication thermal analysis (Task 2), fabricated parts performance (Task 3), microstructure control methodology (Task 4), respectively. These tasks are designed to answer the questions and solve the problems in the results of preliminary experiments and observations from reported investigations. 5.1. Task 1. Investigating feasible formation conditions and effects of laser power…

stories about environmental disasters including global warming, endangered species, deforestation, nuclear accidents and much more. We fail to realize how important it is to keep the environment we live in. Without…

Pollution, acid rain, toxic waste, global warming, sustainability, recycling; these terms are thrown into society and people start to believe there may not be a solution to the endless usage of oil, buildup of landfills, and seepage of chemicals into rivers. While there will always be individuals who fight against the possibility of going green, it just takes one individual at a time to make a difference. From the simple solution of planting a garden suggested by Pollan to the extensive research…

The world is in denial, climate change is happening, and the earth is dying because people are killing it. A clear example of this denial is seen in the decline of news coverage regarding environmental change, “in 2007, the three major U.S. networks—CBS, NBC, and ABC ran 147 stories on climate change; in 2011 the networks ran just fourteen stories on the subject” (Klein, 34). People do not want to hear about climate change and decreasing natural resources. Continued denial will be the downfall…

Global Warming and the American Economy “What’s good for the environment is good for the economy (Trzupek qtd. Chicago Department of Environment Official).” As Americans our lives are greatly impacted by the economy. Most families today were effected in some way from the recent economic depression that our country experienced. Many lost their jobs and some ultimately lost their homes. It was an extremely difficult time for individuals and businesses. Although recovering from the economic…

a long history of contaminated land in England, Its past industrial revolution which took place long before modern systems of environmental controls on process emissions and waste disposal were in place, has led to the current state of land contamination. This essay will discuss the provision of the current contaminated land regime, its interaction with other environmental cleanup groups in the UK, and its complications. It will further look at it in reference to the UK 's planning authority.…

Are Canada’s efforts towards changing our overall environment and being informed on our climate change issues effective? Canada is failing in the efforts towards improving their environmental impact. The earth’s climate is changing and developing rapidly. There are many reasons as to why our environment is the way it is to this day. This discussion topic has been going on for many years now and will continue to do so for the next hundreds of years as it changes and develops drastically,…
