Sample Essay All biometric technologies have limitations of one sort or another that keep them from achieving their theoretical accuracy. Fingerprint recognition has an advantage over other biometrics because multiple fingers can be used to attain extremely high accuracy, if the application requires it.
Sample Essay According to the World Future Council (2010), the use of scientific disciplines such as chemistry in form of green chemistry will help reduce pollution by chemical substances further reinforcing the war against environment destructions. Finally, technological manipulations of physical properties of components by nanotechnological procedures can be said to be a huge milestone …
Sample Essay Another important phenomenon that green technology advocates for, is green purchasing or environmentally prefered purchasing or buying (EPP) (Sobha, 2008, p. 104). It is estimated that we would need five earths to satisfy our needs if everybody else consumed like those people in developed world. Every manufactured product has a life cycle that …
Sample Essay Chemistry is assumed by many now as the mother of planet and life. This philosophy has transmitted its effects to environment conservation meaning that much chemistry related applications could serve to conserve the environment. However, advancements in the field of chemistry have resulted into massive destruction of the environment. Green chemistry is believed …
Sample Essay In the year 2005, a scientist named Ryōji Noyori successfully introduced three innovations that boosted understanding and application of green chemistry (Geeta, 2007, p. 64). He proposed the use of supercritical carbon dioxide as a solvent, which he presumed green. He also developed clean oxidation pathways using aqueous hydrogen peroxide and finally the …
Sample Essay This new field is being mobilized in efforts to conserve the environment through green technology. It operates on almost similar grounds as green chemistry but focuses more on physical chemistry. Nanotechnology involves active manipulation of basic particles of an element namely protons and neutrons (Bharat, 2007, p. 31). These manipulations culminate into chemical …
Sample Essay It was until 1970s when the world realized the need to come up with green building. This reality pushed for establishment of environment friendly buildings whose function is not to house people and their properties but also to used energy in the most efficient and sustainable manner (Sobha, 2008, p. 27). Installation of …

Sample Essay Nanoproducts have been known to improve quality of other products. This is after their physical properties are altered. For instance, by shrinking particle sizes, these products may posses some of the most important environment friendly properties such as occupying small space, or having a large surface per volume ratio. These changes in physical …
Sample Essay Other forms of environment friendly uses of nanotechnology include chemical filtration, tissue engineering, manufacture of less toxic aerospace gadgets, recycling plants for wastes such as batteries, which are known to cause a lot environmental problems when disposed incorrectly. Nanofoods have also been created using this green technology (Bharat, 2007, p. 94). Canola oil …
Sample Essay Software components of technology are useful in enhancing student learning by providing necessary technological skills and supporting learners’ technology literacy skills (Dugan, 2002, p. 210)through such programs like video presentations with digital cameras, word processing documents, school yearbook and PowerPoint presentations. Furthermore, computer based programs that are installed into the hardware can facilitate …
