Nanotechnology In Architecture

Nanotechnology In Architecture Historically and geographically human have lived in extremely varied technology or environment and have had to adapt to comfort habitats and thus the architects have had to manage the ideal of design as well as incorporate the evolutionary technology. A technology has evolved to a level where it is just too complex. Sometimes satisfying the need of the user and sometimes becoming too dangerous when the negative consequences are not taken care of. For example, the issues of the Large scales in architecture is one such matter which has been partially solved with the help of low cost materials, energy savingà ¢Ã¢â€š ¬Ã‚ ¦etc. The scientists have developed and are continuing to develop nanotechnology to help architects incorporate more artificial intelligence in construction. Nanotechnology is a combination of various fields of science like, Bio- technology, Chemistry, Physics, Bio-informatics, etc. There are three chief divisions in Nanotech: Nanoelectronics, Nanomaterials, and Nano-Biotechnology. Worldwide, there is much enthusiasm about nanotechnology as it has application in medicine, electronics, biomaterials, energy etc. It is observed that US, Japan, and Germany dominate the current RD effort in nanotechnology with a focus on they own expertise and needs (Hyd and spook, 2012). The use and control of the technology at an atomic or particle scale known as nanotechnology has started to have its impact like never before in materials of constructions and has immense futurist impact in architecture, this application of the nanotechnology and nanomaterials in architecture is NanoArchitecture. The nano world in technology is a real challenge for todays designers, it started with an understanding and control of the technology and materials on one billionth (10-9) scale. The understanding of these materials, its use in architecture to be profitable for users and its implication on the building (Construction) are some of the key aspect for inquiry in this dissertation. With the perfect solution of this dilemma, the Architects would not only know how big their task is but how it might lead to new ways of thinking architecture. After understanding the meaning and origin of this technology, we will study certain aspects that is a must in todays constructions and then we see the direction where this science is going, we will also look at the ways to incorporate these technologies in our architecture, therefore the question that will guide our research is how does nano (technology, materials, science, concept, form and function) become important to the level of influencing architects (designers). Nanotechnology is developed in the manner that it is active or passive, this repartition will lead us to a large study but our focus will rely on the relation passive active nanostructure and application of nanotechnology in a building design and construction. Passive nanotechnologies, such as nanocoatings, nanoparticles, and nanostructured materials, are already available. Second generation active nanostructures, for example, nanoelectro-mechanical systems, nanomachines, self-healing materials, and targeted chemicals, can evolve their properties, structure and/or state during their operation. This could increase nanotechnologys impacts and require new approaches for risk assessment. Active nanostructures are likely to have a different and increased profile of impacts (including benefits as well as potential risks) compared with passive nanotechnologies. RESEARCH QUESTION: How does nano (technology, materials, science, concept, form and function) becomes important to the level of influencing architects (designers). NEED IDENTIFICATION: Over the years the materials used in buildings (during construction, inside or outside finishes) has been of a large scale, the evolution today have brought into existence the materials on a microscopic scale with even more value to life and building. They can be metals, ceramics, polymers or composites. Known as nanomaterials, nanocomposites, and manufactured nanomaterials (MNMs), the method of making these materials begins at the molecular or atomic level, sometimes creating new products with extraordinary physical and chemical properties. For example, a carbon nanotube has strength of 150 times that of steel but is approximately six times lighter. Besides strength enhancement, properties can include self-cleaning, super hardness, electrical conductivity, antimicrobial superior thermal resistance and stability, non-flammability, lightweight, anti-corrosion, superior barrier, light emitting and low permeability, among others. Applications in the building industry include use as fire retardants, high performance insulation, protective coatings, equipment lubricants, structural integrity enhancement and monitoring, photovoltaic, stronger tensile cables, and self-cleaning or heat absorbing windows ( CFN, 2011 )à ¢Ã¢â€š ¬Ã‚ ¦ Using these materials which contain extraordinary application in the building can also bring amazing influences to the architect, designer or the design. Therefore apart from attempting to understand the transformation that the nanotechnology brings to our building there is a need to understand by students the uses of nanotechnology for creating better design. SCOPE: à ¢Ã¢â€š ¬Ã‚ ¢ A general understanding of nano especially toward architecture à ¢Ã¢â€š ¬Ã‚ ¢ Nanotechnology (materials) applications in buildings à ¢Ã¢â€š ¬Ã‚ ¢ Concept; form and function derived from nano LIMITATION: à ¢Ã¢â€š ¬Ã‚ ¢ The laboratories details of certain materials and nano applications in medical branches will not be part of our research. à ¢Ã¢â€š ¬Ã‚ ¢ This research dissertation will have some limitation in details like calculations, manufactures process, chemical components. à ¢Ã¢â€š ¬Ã‚ ¢ Thinking in more detail about how to use nanomaterials in a design context, a first consideration is simply to define what is being design?. But there is a lack of built case studies, so we will rely on existing, futurist, basic concept and reading materials. à ¢Ã¢â€š ¬Ã‚ ¢ Regarding the size of this matter nanotechnology, we will limit at the level where nanotech is active and very briefly talk about the passive Nanotechnology RESEARCH METHODOLOGY: N A N O A R C H I T E C T U R E PART O.

The reading of the applications in nanotechnology in todays constructions is more related to Green designers, this part of the design has an impact in the ecology and climate control therefore the green rated buildings has in fact a considerable amount of nanotechnology use in it. This leads us to refer to architects involved in green concepts or sustainability from LEED etc ( Ar Alex Nyembo Kalenga) and also we could make a visit studies on the actual certified Green building Rajiv Gandhi urja Bhavan at Vasan Kunj New Delhi Still in Construction.

Fundamental Knowledge II.1.1. WHAT IS NANOTECHNOLOGY? A brick is the smallest building block in construction. Whatever you do, the strength of the building is limited to the strength of the brick. The brick itself is made of minute particles of clay bonded together. One has limited control over how the particle of clay forms. Each particle of clay in turn is formed from molecules joined together in a particular pattern dictated by the forces of nature. What happens if it is possible to arrange these molecules in a pattern that provides greater strength? You get stronger clay and a stronger brick. This results in a much thinner, but stronger wall. This technology of arranging molecules the way we want is a basis of nanotechnology. (Johnzactruba, 2011) A strict definition of nanotechnology characterizes it as the manipulation of a matter at the scale of one-billionth of a meter or smaller. The measurement of one-billionth of a meter is identified as one nanometer (nm) (Jeffrey H. Matsuura,1957). Nano, is a word which does not only mean billionth less but also leaves a billionth of question in mind, because of the complexity to understand its simplicity. It is a world hold by the scientist, chemist and physicians. Yes nanotechnology is a relatively recent development in scientific research but not new. The level of its study and diversity has involved touching now many sector of life and becoming more and more known by the public. The concept first was introduced by American physicist Richard P. Feynman (1918-1988). But it is noted that in the 10th centuries the 16th centuries the ruby-red color of many stained-glass windows from the medieval era was a consequence of embedded nanoscale metallic particles within the glass. There were no scientific understanding of these phenomena at the time, nor were there deliberate attempts to produce what we now know as nanomaterials. Early knowledge relied on craft-based trial and error to achieve effects we must keep in mind, however, that not all interesting color phenomena are a result of embedded nanomaterials ( Michael F. Ashby, 2009). The evolution of nanotechnology has been more or less in the domain of chemical, medicine and physics (technique) then it involved to the environment, energy, agriculture, communication and information because of some of its advantage and disadvantage in the society. The main tools used in nanotechnology are three main microscopes: Transmission Electron Microscope (TEM), Atomic Force Microscope (AFM), and Scanning Tunneling Microscope (STM). (Jamie Jackson, CIS 121) II.1.2. NANO PRODUCTS Use as gateways to build other nano products, Nanosensors can be chemical sensors or mechanical sensors. Amongst other applications they can be used: à ¢Ã¢â€š ¬Ã‚ ¢ To monitor physical parameters such as temperature, displacement and flow à ¢Ã¢â€š ¬Ã‚ ¢ As accelerometers in Microelectromechanical systems (MEMS) devices that can rapidly and remotely detect change in their surroundings like airbag sensors à ¢Ã¢â€š ¬Ã‚ ¢ For medical diagnostic purposes either as blood borne sensors or in lab-on-a-chip type devices à ¢Ã¢â€š ¬Ã‚ ¢ To detect various chemicals in gases for pollution monitoring à ¢Ã¢â€š ¬Ã‚ ¢ Sensors using carbon nanotube detection elements are capable of detecting a range of chemical vapors. These sensors work by reacting to the changes in the resistance of a carbon nanotube in the presence of a chemical vapor ( Hawks Perch Technical Writing, 2007). II.1.2.1. Nanotube Known as well as Carbon Nanotube (CNTs), it is a tube-shaped material or cylindrical nanostructure made of carbon, having a diameter of nanometer scale. Nanotubes form a tiny portion of the material(s) in some baseball bats, golf clubs, or car parts. Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (GPa). Since carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm3, its specific strength of up to 48,000 kNà ¢Ã¢â€š ¬Ã‚ ¢mà ¢Ã¢â€š ¬Ã‚ ¢kgà ¢Ã‹â€ Ã¢â‚¬â„¢1 is the best of known materials, compared to high-carbon steels 154 kNà ¢Ã¢â€š ¬Ã‚ ¢mà ¢Ã¢â€š ¬Ã‚ ¢kgà ¢Ã‹â€ Ã¢â‚¬â„¢1. Standard single-walled carbon nanotubes can withstand a pressure up to 24GPa without deformation. The bulk modulus of super hard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal) and can produce materials with toughness unmatched in the man-made and natural worlds. Because of the carbon nanotubes superior mechanical properties, many structures have been proposed ranging from everyday items like clothes and sports gear to combat jackets and space elevators. However, the space elevator will require further efforts in refining carbon nanotube technology, as the practical tensile strength of carbon nanotubes can still be greatly improved (Wikipedia, 2012). II.1.2.2. Nanocomposites The definition of nano-composite material has broadened significantly to encompass a large variety of systems such as one-dimensional, two-dimensional, three-dimensional and amorphous materials, made of distinctly dissimilar components and mixed at the nanometer scale (Kanatzidis, 2006). New materials with novel proprieties are generate rapidly through this field. The properties of nano-composite materials depend not only on the properties of their individual parents but also on their morphology and interfacial characteristics. Although nanoscale reinforcements (or nanofillers) of nanocomposites have different kinds of fillers such as nanofibers, nanowires, nanotubes and nanoparticles etc, their mechanical behaviors have some common features. As the figure shows a potential use of nanocomposites as multifunctional materials (Journal Club, 2008). AREA OF APPLICATION Such mechanical property improvements have resulted in major interest in nanocomposite materials in numerous automotive and general/industrial applications. These include potential for utilisation as mirror housings on various vehicle types, door handles, engine covers and intake manifolds and timing belt covers. More general applications currently being considered include usage as impellers and blades for vacuum cleaners, power tool housings, mower hoods and covers for portable electronic equipment such as mobile phones, pagers etc (Professor J.N. Hay, 2001). The inorganic components can be three-dimensional framework systems such as zeolites, two-dimensional layered materials such as clays, metal oxides, metal phosphates, chalcogenides, and even one-dimensional and zero-dimensional materials such as (Mo3Se3-)n chains and clusters. Experimental work has generally shown that virtually all types and classes of nanocomposite materials lead to new and improved properties when compared to their macrocomposite counterparts. Therefore, nanocomposites which combine new nanomaterials with more traditional ones such as steel, concrete, glass, and plastics, can be many times stronger than standard materials and promise new applications in many fields such as mechanically reinforced lightweight components, non-linear optics, battery cathodes and ionics, nano-wires, sensors and other systems. On the market there already a nanocomposite steel that is three times stronger than conventional steel. Before long, nano-reinforced glass might be used for both structure and enclosure. In the some student projects in the nanoSTUDIO at Ball State University, nanotube structural panels create transparent load-bearing curtain walls free of columns and beams, quantum dots make walls and ceilings light up or change color with the flip of a switch, and nanosensors in building components create smart environments that constantly adapt to their environment and users. II.1.3. TYPOLOGY M. C. Roco, one of the driving forces behind the NNI, has developed a more detailed typology of nanotechnologies. He identifies four generations of nanotechnologies: passive nanostructures, active nanostructures, systems of nanosystems and molecular nanosystems (J. Clarence, 2009) ( Fig04: For generation of nanotechnology development, Center for Responsible Nanotechnology ) Each generation of products is marked by the creation of commercial prototypes using systematic control of the respective phenomena and manufacturing processes. Products may also include components which correspond to different generations. Todays rudimentary capabilities of nanotechnology for systematic control and manufacture at the nanoscale are expected to evolve significantly in both complexity and the degree of integration by 2020. II.1.3.1 Passive to Active nanotechnology It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment. An active nanostructure changes or evolves its state during its operation, according to the National Science Foundations (2006) Active Nanostructures and Nanosystems grant solicitation. Passive: (steady function) nanostructures Behaviour: inert or reactive nanostructures which have stable behaviour and quasi -constant properties during their use. Potential risk: e.g. nanoparticles in cosmetics or food with large scale production and high exposure rates. Active: (evolving function nanostructures) Behaviour: the nanostructures properties are designed to change during operation so behaviour is variable and potentially unstable. Successive changes in state may occur (either intended or as an unforeseen reaction to the external environment). Potential risk: e.g. nanobiodevices in the human body; pesticides engineered to react to different conditions. Categories of active nanostructures are: à ¢Ã¢â€š ¬Ã‚ ¢ Remote actuated active nanostructures, such as light-actuated embedded sensors; à ¢Ã¢â€š ¬Ã‚ ¢ Environmentally responsive active nanostructures, such as responsive drug delivery; à ¢Ã¢â€š ¬Ã‚ ¢ Miniaturized active nanostructures, such as synthetic molecular motors and molecular machines; à ¢Ã¢â€š ¬Ã‚ ¢ Hybrid active nanostructures, or uncommon combinations of materials, such as silicon-organic ; à ¢Ã¢â€š ¬Ã‚ ¢ Transforming active nanostructures, such as self-healing materials. (M.C. Roco, 2004, 2007) Tour estimates the time it will take to commercialize each of these types as 0-5 years for passive nanotechnologies, 15-50 years or more for active nanotechnologies and 7-12 years for hybrids (J. Clarence, 2009) II.1.4. WHY ALL THE FUSS ABOUT NANOTECHNOLOGY? NANOTECHNOLOGY: THE SCIENCE CHANGING YOUR LIFE Penny Sarchet The advantages of using nanomaterials in construction are enormous. When you consider that 41 percent of all energy use in the United States is consumed by commercial and residential buildings, the potential benefits of energy-saving materials alone are vast (Dr. Pedro Alvarez of Rice University, 2010) and when we have to evaluate the energy used by buildings in the rest of the world the result will surly show that the use of the nanomaterials in buildings will be of an anxiety necessity. Nanotechnology thus has profound potential because it can free us from some traditional limits and offer us useful new capabilities. Nanotechnology can change some of the physical rules that have traditionally confined us. It can also free us from some of the limitations that have long been placed upon us by size ( Jeffrey H, 1957). The key is to understand the specific risks and implications of the product before it is widely used. This way we can ensure that nanotechnology evolves as a tool for sustainability rather than as an environmental liability (Dr. Pedro Alvarez of Rice University, 2010). Benefices and profit with the nanotechnology is now in the hand of everyone and architects are with no doubt going to shape this realm to another level. e.g.: Solera enables seamless integration of natural daylight into the design and function of buildings. Well daylighted spaces deliver substantial and measurable benefits to sustainability, energy efficiency and human performance. This series of products provide architects with solutions to solve the challenges traditionally associated with daylighting techniques including solar heat gain, cost, complexity and glare. Other materials such as brickà ¢Ã¢â€š ¬Ã‚ ¦ have already showed us the changes that it has done to the industries, life, designers, buildersà ¢Ã¢â€š ¬Ã‚ ¦ In the early days, paint was available in a limited variety of colors for you to choose. Now most of the paint shops have mixers that allow the users to choose the color they require. The manufacturers have to produce and stock only a few basic colors, reducing production and inventory costs at much greater satisfaction to the consumer. The future of nanotechnology will be the personal nano-factories, like the paint mixers, that allow you to produce any material that you require. The shops have to carry only stock in molecular form. Advances in nanotechnology are moving at an exponential rate. It will eventually encompass every field of human activity including energy. (Johnzactruba, 2011) Disadvantages of Nanotechnology: Safety hazards with nanomaterials, Some studies detected possible cancer-causing properties of carbon nanotubes, Some nanomaterials bounded with other materials or components (Jamie Jackson, CIS 121) II.1.5. RISK OF NANOTECHNOLOGY It is obvious to find out that except from the greatness and impressive opportunities that nanotechnology offers, the risks are associated with it as well. And these risk touch-up on Health, environment, Industryà ¢Ã¢â€š ¬Ã‚ ¦ Because of the size of the particles, nanomaterials may enter human and other living bodies and disrupt body-functions. Some nanoparticles may also be non-biodegradable thereby posing a new threat to the environment. Therefore it is crucial to examine and estimate the risk for regulating the production, use, consumption and disposal of these materials. (Hyd and spook, 2012). For example, Health effects of several insulating materials are a concern; 1. The fibers released from fiberglass insulation may be carcinogenic, and fiberglass insulation now requires cancer warning labels. 2. There are also claims that the fire retardant chemicals or respirable particles in cellulose insulation may be hazardous (Dr. George, 2007). The risk most talked about is the ability of nanotech carbon tubes to potentially cause asbestosis-type illnesses, (Mike Childs, 2012) Manufactured nanomaterials (MNMs); and nanocomposites are being considered for various uses in the construction and related infrastructure industries. To achieve environmentally responsible nanotechnology in construction, it is important to consider the lifecycle impacts of MNMs on the health of construction workers and dwellers, as well as unintended environmental effects at all stages of manufacturing, construction, use, demolition, and disposal. Emphasis in industries; In India, late industry participation has also begun in this area, and there is an emphasis on fostering public-private partnerships (PPP). Nonetheless government support to this sector remains crucial for three reasons: 1. Nanotechnology is a capital-intensive technology and is in an embryonic phase, thus industry would not be able to sustain the research effort needed for the establishment of scientific and technological infrastructure. 2. The state is required to define the regulatory framework. In 2010-11 this process was initiated. 3. The state ,particularly in the developing country context, can set the agenda and resist the tendency to uncritically follow international trends in research that do not address their developmental needs.

III.1. Environmental application Environmentally, Nanotechnology also has the potential to help our environment. Example: It controls pollution through source reduction. This is a method of eliminating toxic waste at its source, with the understanding that releasing the waste into the environment is the last resort. Source reduction can be achieved by cleaning up existing processes or by reducing consumption of resources where such consumption creates pollution. III.1.1. Insulation The impact of the improvement of insulation reductions is counted by billions of pounds annually. Ref table (Fig06: Potential sources of EU CO2 emission reductions ) Nanoscale materials hold great promise as insulators because of their extremely high surface-to-volume ratio. This gives them the ability to trap still air within a material layer of minimal thickness (conventional insulating materials like fibreglass and polystyrene get their high insulating value less from the conductive properties of the materials themselves than from their ability to trap still air.) Insulating a nonmaterial may be sandwiched between rigid panels, applied as thin films, or painted on as coatings (Dr. George, 2007) Nanogel panels; Aerogel This material as an incredible ability and capacity such as strength, it can take its own load 2000 times reminding that it has only 5 percent solid and the rest is filled with air only an are also applicable on fabric architecture or structures. Because nanoporous aerogels can be sensitive to moisture, they are often marketed sandwiched between wall panels that repel moisture. Aerogel panels are available with up to 75 percent translucency, and their high air content means that a 9cm (3.5) thick aerogel panel can offer an R-value of R-28, a valu

McClelland and Maslow Theory Essay

American’s Psychologist David Clarence McClelland (1917-98) proposed that every individual have specific needs that can be classed into need for achievement (nAch), need for affiliation (nAff), and need for power (nPow). Regardless of gender, culture or age, human beings have three motivating drivers that will affect their behavior. People with a high need for achievement seek to excel, to accomplish in relation to a set of standards, to struggle to achieve success. High nAch individuals prefer work that has a moderate probability of success, ideally a 50% chance. There is a strong need for feedback as to monitor the progress of their achievements. They prefer either to work alone or with other high achievers. High achievers are not interested in rewards or money unless these rewards reflect a measurement of their success. Their desire is to do a task better than it has been done before. The individuals with high achievement needs are highly motivated by competing and challenging work. They also look for promotional opportunities in job. Second, the individuals who are motivated by affiliation have an urge for a friendly and supportive environment. They prefer to spend time creating and maintaining social relationships, enjoy being a part of groups, and have a desire to feel loved and accepted. Individuals with high nAff strive for friendships, prefer cooperative situations rather than competitive ones, and desire relationships involving a high degree of mutual understanding. Individuals having high affiliation needs prefer working in an environment providing greater personal interaction. Such people have a need to be on the good books of all. They generally cannot be good leaders. A high need for power may be expressed as â€Å"personalized power† or â€Å"socialized power†. Those with a high need for power work best when they’re in charge. Because they enjoy competition, they do well with goal-oriented projects or tasks. They may also be very effective in negotiations or in situations in which another party must be convinced of an idea or goal. Those who need personal power want to direct others, and this need often is perceived as undesirable. Persons who need institutional power (also known as social power) want to organize the efforts of others to further the goals of the organization. Managers with a high need for institutional power tend to be more effective than those with a high need for personal power. McClelland’s theory of Needs allows for the shaping of a person’s needs; training programs can be used to modify one’s need profile. The use of this information is to lead, praise, and motivate your team more effectively, and to better structure your team’s roles. Maslow Theory In 1943 a Psychologist Mr. Abraham Harold Maslow suggested his Theory of Human Motivation. According to him, our actions are motivated in order achieve certain needs. This hierarchy suggests that people are motivated to fulfill basic needs before moving on to other, more advanced needs. The hierarchy of needs includes five motivational needs, often depicted as hierarchical levels within a pyramid. Maslow identified five types or sets of human need arranged in a hierarchy of their importance and priority. They are physiological, safety, love, and esteem and growth needs (self-actualization). Physiological needs are the basic needs for sustaining human life. These needs include food, shelter, clothing, rest, air, and water. These needs cannot be postponed for long. Unless and until these basic physiological needs are satisfied to the required extent, other needs do not motivate an employee. Second is safety, these include needs for safety and security. Security needs are important for survival, but they are not as demanding as the physiological needs. Examples of security needs include a desire for steady employment, health care, safe neighborhoods, and shelter from the environment. Next is social needs. An employee is a human being is rightly treated as a social animal. He desires to stay in group. He feels that he should belong to one or the other group and the member of the group should accept him with love and affection. He needs friends and interaction with his friends and superiors of the group such as fellow employees or superiors. After the first three needs have been satisfied, esteem needs becomes increasingly important. These include the need for things that reflect on self-esteem, personal worth, social recognition, and accomplishment. Lastly is self-actualization. Self-actualization is the desire to become what one is capable of becoming. It is a ‘growth’ need. A worker must work efficiently if he is to be ultimately happy. Here, a person feels that he should accomplish something in his life. He wants to utilize his potentials to the maximum extent and desires to become what one is capable of becoming. Though everyone is capable of self-actualization, many do not reach this stage. This need is fully satisfied rarely.

Disneys Brands Success - 1371 Words

The Walt Disney Company has been successfully creating and capturing value for their customers for over nine decades. With a net worth of 74.9 billion dollars, Disney has claimed the title as of one of the most profitable companies in the world. Their product line is extensive, as they currently own and run a successful media network, several theme parks and resorts worldwide, an extensive merchandise line, a studio entertainment sector, as well as Disney Interactive. Disney’s brand’s success hinders on several points of difference that have allowed the company to flourish. Firstly, Disney creates an undeniably unique experience for its customers. The theme parks have a â€Å"magical† feel to them, which keeps families coming back for decades.
