Nanotechnology Uses to Enhance Computer Performance Essay Example for Free

Nanotechnology Uses to Enhance Computer Performance Essay Although the core concepts of nanotechnology were introduced in the early 1950’s, nanotechnology was not properly introduced to the world until 1974. That was the year a Japanese scientist, named Tanigushi, coined the word â€Å"nanotechnology†. Nanotechnology refers to the constructing and engineering of systems at the atomic level. â€Å"Nanotechnology will be the major technology in development of every machine in coming years. † (Wifinotes, n. d. ) Nanotechnology will greatly improve the functionality and performance of computers. Body  In everyday terms, â€Å"Nanotechnology is based on manipulations of individual atoms and molecules to build complex atomic structures. † (Tarasov, 2009, pg. 1) Working at the atomic level is a very new technology. The size of a nanometer is one-billionth of a meter. For comparison purposes, â€Å"A very fine human hair is about 10,000 nanometers wide, which is the smallest dimension we can see with the naked eye. † (Cook, 2005) Before research could begin, researchers had to first invent a machine that could work with such small particles. Their goal was to manipulate atoms and molecules into a particular configuration – a configuration capable of performing functions similar to a microprocessor. The technology prior to nanotechnology started out rather primitive. It was a major advance in technology when vacuum tubes were invented. They came into existence about the same time Thomas Edison invented the light bulb. Vacuum tubes were first used in computers in 1946 until 1958. By then, vacuum tubes could not be made any smaller, so technology gave us transistors. Transistors were used in computers from 1959 to 1964. One transistor took the place of 40 vacuum tubes. When the limits of the transistor were reached, computer builders used integrated circuits from 1965 to 1970. In 1971, the microprocessor came into computer use. Faster and smaller than anything so far, the microprocessor led to the invention of personal computers. Now that the advancement of microprocessors has nearly reached its limits, it is now time for the next generation of processor, which some researchers say will be engineered on the nanometer scale. But, how will they manipulate particles on such a minute scale? Before manipulating atoms into the desired position, researchers had to see them first. Researchers had to invent a microscope that would allow them to see atoms. In 1981, IBM researchers invented the Scanning Probe Microscope (SPM). (University of Wisconsin, 2008) This microscope allowed researchers to â€Å"see† atoms. As it turns out, in 1989, researchers found they could actually manipulate atoms into the desired position with the SPM. †¦researchers have been able to manipulate and stabilize atomic-size structures in such a way that they can persistently maintain the qualities needed to be classified as viable, though still strictly experimental, computational devices. † (Goth, 2012) Atoms are constantly moving, so catching one to move around was very difficult. The atoms needed to be cooled down to near absolute zero, to -450 degrees Fahrenheit, the temperature where most atoms hardly move. The Scanning Probe Microscope (Nanooze, 2005) After cooling the atoms, researchers were able to use the SPM to move individual atoms to a specific location. One at a time, they moved the atoms into position to spell â€Å"IBM†. It took them nearly an entire day to do it. See image below: Atoms arranged to spell IBM (Nanooze, 2005) Since the first manipulation of atoms had been demonstrated, researchers have continued to move atoms into complicated configurations, as shown in the figure below. Depiction of a nanotechnology produced gear set (Wifinotes, n. d. ) After all the groundwork had been laid, computer researchers turned their attention to using nanotechnology in the computer world. Their first target was the microchip. Current microchip technology limits have nearly been reached and the researchers went to work shrinking the size of the processors . â€Å" etching [lithography] techniques can only take features so far – anything below 22nm is just not feasible. † (European Nanotechnology Gateway, n. d. ) Right now, the newest chipsets using lithographic etching are being produced with 65nm features. Intel has realized a 10-15% improvement in drive current, which means greater performance, through the use of nanotechnology. Meanwhile, at IBM, to aid the shrinking of the processors, â€Å"researchers have developed transistors from carbon nanotubes. †( European Nanotechnology Gateway, n. d. ) Carbon nanotubes show great improvements compared to conventional silicon transistors. â€Å"The carbon nanotubes are long, thin strands of carbon molecules. In the lab, they delivered more than double the amount of electrical current compared to the top-performing transistors currently on the market. †( European Nanotechnology Gateway, n. . ) â€Å"A single strand of carbon atoms (red)†¦contained in a multi-walled carbon nanotube. † (American Institute of Physics, 2003) Lithographic etching is being replaced with a new process called â€Å"block co-polymer lithography†, or BCP. Scientists have found a process to create nano-scale patterns that is expected to be used in the manufacture of microprocessors. Using the new process, silicon wafer features have been developed between five and 20 nanometers thick – much smaller than the current 65 nanometers. In the figure below, you can see an image of a nano-scale microprocessor created by the BCP process: (Nanotechnology, 2011) According to Nanotechnology – Future Technology: †¦with the use [of] nanotechnology, it could be possible to transform desktop computers into computers that are the size of a watch but with more operating capacity and they will also last longer than current computers†¦Computers with the capabilities of current workstations will be the size of a grain of sand and will be able to operate for decades with the equivalent of a single wristwatch battery. This technology advancement will make computers more abundant, cheaper to manufacture, faster, and smaller. (Nanotechnology – Future Technology, 2012) When a processors feature size is reduced, it uses less electricity and produces less heat, thereby becoming more efficient and economical to operate. Being more efficient and economical also means faster, more reliable overall performance of the computer. Conclusion Nanotechnology will provide the world with advancements in electronics along with many other fields, such as biology, chemistry and medicine. In the future, nanotechnology will play a major role in the discovery of new components, such as nano-sized microprocessors, and will enhance many other existing technologies. â€Å"Nanotechnology will be the major technology in [the]development of every machine in coming years. † (Wifinotes, n. d. ) Nanotechnology will greatly improve the functionality and performance of computers.

The Power of Conformity There are many type of social concepts; however, there is one that I personally experienced through: social conformity. Conformity is a type of social influence involving a change in belief or behavior in order to fit in a group. Growing up as an immigrant is a perfect example for changing me in order to adapt to a new environment. Conformity can also be simply defined as â€Å"yielding to group pressures† (Crutchfield, 1955). Group pressure may vary in many forms such as bullying, persuasion, teasing, or criticism. Conformity is also known as group pressure. The term conformity is often used to describe one side arguing with the other side by a desire to ‘fit in’ or be liked, or because of a desire to be correct, or simply to conform to a social role. The desire to be accepted and belong to a group is every human’s need. However, how does this need affect an individual? There are many researches that include groups can change their members’ thoughts, feelings and behaviors. There are several types of conformity include compliance, internalization and identific...

My First Day in School

Today also when I recall my old memories of school I become delighted and happy. First day of my school when I admitted in class I. When first time I entered in my school numerous felling were aroused in my mind and i was felling nervous and bit tensed. Although I was not a brilliant student not knowing even alphabets my teachers helped me in learning the alphabetsThat was the time when my first class began Manisha Ma’am entered in the class room every student stood up and greeted good morning Ma’am in return Ma’am replied very good morning sit down I also followed them Ma’am teaches us alphabets and how to use those alphabets in formulating the sentences and words then bell rang Ma’am went outside. Again next teacher entered in the class room and we stood up and greeted good morning Ma’am. Ma’am did not recognised my face as she had never seen me before in the class she immediately asked me the question very politely â€Å"Is this yo ur first class? I replied yes Ma’am then she asked my name I answered â€Å"Rashda Khanam† she said ok Rashda sit down her name was Priyanka very soft, polite and beautiful too. Again the bell rang this time nobody entered in the class room and every student went away along with their lunch box. My mother also gave me the lunch box filled with alu paratha and tomatao chutney. I opened the box and started eating, suddenly my one of my classmate again entered in the class room and said me very politely â€Å"why are you seating alone? come outside I went outside with her along with my lunch box and water bottle hanging in my neck, we all shared our lunch and I became friendly with everybody in the first day of my school, bell rang recess over every body were settled down at their respective places and waiting for the next teacher to come, within 5 mins miss Angilee entered in the class room and asked for the assignment she assigned previous day I found the teacher trict I was seating silently, miss wrote some arithmetics on the blackboard 45 mins passed bell rang every body came out from the class waited for their guardian at the door to come and took them. I saw my father was standing outside with chocolate ice-cream my favourite and then happily I reached my home and shared my first day experience with my parents. So this was my first day school and I am very pleased in recalling that day.

The Effect of Music on Behavior Essay - 1145 Words

The Effect of Music on Behavior Music has a huge impact on the everyday lives of individuals in America today. It is an important part of the sociological self, which causes a person to feel and act in a certain manner. Sensual guitar playing, a suggestive song, hard rock power chords, or a tune from the past are all highly powerful forces in shaping ones actions. I have taken a particular interest in the way that different genres of music affect students actions at this university. This paper will take into account the effects that particular genres of music have on people. Because we are in a college town such as Austin it is easy to observe the effects that music has on people. Whether it be at parties, clubs, concerts, or†¦show more content†¦There is no doubt that these actions are the direct effect of this particular music. This type of music can lead to a state of mind where these activities are a main focus in a persons way of life. According to Freud, the id is the part of the person whic h desires certain things, but is controlled by the ego and superego (Freud, 65-68). When a person enters a stage such as this in their life they are completely controlled by the id. The music is an ally to the id, helping it achieve its desires. To illustrate this point further, a closer look at the actions is necessary. A concerts purpose is to allow fans to listen to a band perform live. If the rational part of ones self, the superego, were in control, it is highly unlikely that someone would begin shoving random people to the beat of a song. Though this behavior would not normally be tolerated, it is viewed as acceptable because the participants are at a certain music concert. These actions toe the line between expression and violence. For the most part, this aggressive behavior is instigated and carried out by males. By nature the males of the human species are more prone to violence and exhibitions of strength than females. Music is a powerful means by which these peo ple deem it permissible to act in such a manner. There may be other factors involved with this behavior such as male angst and stress, but the driving force is undoubtedly the music.
