Carbon Nanotubes for Nano-particle Field Extraction Thruster

Carbon Nanotubes for Nano-particle Field Extraction Thruster Using carbon nanotubes as propellant for nano-particle field extraction thrusters Stefan Seuleanu Introduction Carbon nanotubes have been a research focus for more than two decades due to their unique physical properties and have been used so far in a variety of appli- cations. A possible application of carbon nanotubes is their use as propellant for an electric propulsion prototype, the nano-particle field extraction thruster (nanoFET). The nanoFET accelerates and ejects conductive particles in order to provide thrust1 . Its main advantage over other electric propulsion systems, such as ion or arcjet thrusters, is its variable specific impulse and thrust, while maintaining a high internal efficiency1 . Theoretically, the nanoFET propulsion system can be used for a large range of orbital and deep space exploration sit- uations, offering the possibility of decoupling the spacecraft design from the propulsion system4 . However, to date, nanoFETs have not been researched ex- tensively and much of the experimental work is still to be expected. This paper will investigate the possibility of using carbon nanotubes as nanoFET propel- lant by considering their relevant physical properties. By understanding how the nano-particle field extraction thruster works,this account also motivates the use of carbon nanotubes as propellant, despite their current high price. Properties and characteristics of CNTs Firstly, it is important to understand the relevant characteristics that make CNTs desirable for the nanoFET propulsion system. A carbon nanotube is a tubular/cylindrical structure that can be visualized as a wrapped sheet of graphene (one atom thick, two dimensional carbon based hexagonal lattice). Their size is typically a couple of nanometers in diameter and can span many micrometers in length. Carbon nanotubes can be single-walled (SWNTs) or multi-walled (MWNTs). These two characteristics will determine their aspect ratio (ratio between length and diameter), which is generally very high. As will be explained later on, the aspect ratio is a determinant factor that influences the nanoFET performance2,3 . The geometric structure of the nanotube determines its electrical properties. Based on the chiral vector (n,m), illustrated below, there are three main types of CNTs: zigzag, armchair and chiral. When n − m is a multiple of three, then the CNT is metallic, and semiconducting otherwise. Due to their geometry, armchair CNTs are always metallic, while the other types can be metallic only with the right choice of (n,m). Because there is no exact way to synthesize carbon nanotubes of only one geometry, as expected, generally one third of the synthesized CNTs are metallic and the rest are semiconducting 2,3 . Figure 1: CNT type depends on the chiral vector2 . Regarding the nanoFETs, the desired CNTs are the metallic type which implies the necessity for prior sorting before use. Moreover, the synthesized CNTs can contain geometrical †defects† that can be manipulated to improve the thruster’s performance3 . Due to the fact that the CNTs’ structure/geometry minimizes the collisions between conducting electrons, the resulting metallic tubes are highly conductive. Another characteristic is determined by the strong carbon bonds that allow high current to flow at low resistivity. This properties will become relevant when explaining the charging stage of the nanoFET 2,3 . The stages of a nanoFET The acceleration of a particle by a nanoFET can be divided into several stages. By assuming that the particles have been already sorted for the desired thrust, the first stage is the transportation of the particles to the charging pad. The transportation of the particles can be achieved either trough a dielectric fluid or through back pressure, hence the difference between wet nanoFETs and dry nanoFETs. For the purpose of this paper only the wet nanoFETs will be con- sidered, as the research done into dry nanoFETs has so far been minimal. The transportation liquid used for the proof-of-concept tests was silicon oil. After the particle is transported to the charging pad, the next stage is the charging process . Here the conductive particle is electrostatically charged to a desired level 5,6,8 . Figure 2: Single nanoFET emission channel cross section5 The next phase is the lift-off and extraction, which represents the application of an electric field, a potential bias between the electrode and the acceleration gates, such that the particle leaves the charging pad and moves upwards towards the liquid’s surface. At the surface, the particle must overcome the surface tension and get extracted from the liquid. After the extraction, the next stage is the acceleration of the particle trough several stacked gates. The gates have alternating insulating and conductive layers, each providing in theory an electric potential of 1000V, leading to a total of 10,000V potential that accelerates a particle to approximately 10km/s. The particle is finally ejected out of the nanoFET and thrust is produced5,6,7 . Particle behavior in nanoFETs In order to understand the behavior of the particle in a gravitational setting compared to a micro-gravitational setting, it is important to identify the forces that act on the particle at different stages in the nanoFET. The four main forces acting on a particle in a gravitational setting are the electrostatic force, the buoyant force, gravitational force and the drag force. As the cylindrical particle is transported to the charging pad, the liquid provides a horizontal inertial force. This horizontal inertial force is assumed to be low and therefore ignored in the calculations. After the nanoparticles are transported to the charging pad (electrode), they are electrostatically charged; thus contact with the electrode is necessary. If the contact is horizontal, along the length, then the charge of the particle is described by6 .: q0,cy−h = 2Ï€rlÃŽ µl El However if the contact is at either ends, so the particle is vertical on the electrode, the charge is the following6 .: l2 q0,cy−v = Ï€ ln( 2l ÃŽ µl El When the cylindrical particle is vertical on the charging pad, it gains more charge and it also requires less electric field to move upwards, as seen in the figure below6 . Figure 3: Vertically vs horizontal oriented particles a) ratio of acquired particle charge; b) ratio of required lift-off electric field6 In order to orient a particle from horizontal to vertical on the charging pad, an intense electric field focused only at one of the particle’s ends is applied. The fabrication defects that are usually present at the ends of CNTs may help to change the orientation of the particle on the electrode, requiring less electric field to create a moment that rotates the CNTs vertically. Additionally to the gravitational force, while still on the charging pad, the particle has to overcome the adhesion and electric image force in order to achieve vertical lift-off5,6 . After the particle leaves the charging pad, it has to move vertically trough the viscous liquid to the liquid surface. Therefore, the adhesion force and the electric image are no longer present; however the drag force now slows the particle’s movement. For a cylindrical particle the formula for the fluid drag used in the nanoFET calculations is given by6 : 2π µl lv D = ln( l ) + 0.193 While moving through the liquid, the particle loses charge as described by q(t) = q0 exp(− t ), where Ï„ = ÃŽ µl 5,6 . Because the particle moves fast through Ï„ ÏÆ'l the liquid, the charged loss is overall assumed to be negligible. Generally, the particle’s equation of motion is described by6 : dv (mp + K ml ) dt = q(t)El − D + Fbuoyant − W. The above equation also takes in account the added mass that is accelerated with the particle where K is a coefficient that depends on the geometry of the particle, while mp is the mass of the particle and ml is the mass of the liquid. In a laboratory gravitational environment the gravitational forces are minimal compared to the dominant drag and electrostatic forces. In a micro-gravitational environment the gravitational force and the buoyant force can be neglected5,6 . Performance and particle size For characterizing the performance of the nanoFET electric propulsion system, the space industry uses specific impulse and thrust-to-power ratio as indica- tors of performance. The specific impulse is the impulse delivered per unit of propellant consumed. In order to achieve a certain thrust, the systems that have higher specific impulse consume less propellant than the ones with lower specific impulse. For the nanoFET system the specific impulse increases as the charge-to-mass ratio of the particle increases. Thurst-to-power ratio describes the amount of thrust outputted for a specific power provided4,6 . 1 q 1 T 2 mp 1 Isp = 0 (2Vo p ) 2 ; = ( ) 2 P Vo q Moreover, the internal efficiency is given by4,6 : 1 T ÃŽ ·int = 2 g0 P Isp There are several factors that can influence the performance or the mode of operation of the nanoFET. First of all, the horizontal inertial force that the particle gains from the transportation liquid is assumed to be negligible. How- ever, this is not necessarily the case and further research needs to be conducted in order to determine its influence. Another important factor is the presence of Taylor cones and surface instability when a high electric field is present near the liquid’s surface. These cones can eject droplets and reduce the performance of the nanoFET. In order to mitigate the surface instability and the ejection of droplets, an experiment has been done to analyze how different particle shapes influence the minimum electric field needed for the extraction process. The ex- periment consists of various vacuum electric fields applied to spherical 800 µm and cylindrical 300 µm diameter and 1.5mm length aluminium particles with a total silicon oil fluid gap of 12 .7mm. As seen in the figure below, cylindrical particles can be extracted before the Taylor cones form5,6,7, . Figure 4: Taylor cone formation and particle extraction6 Furthermore, further study into the charge-to-mass ratio revealed that, for cylindrical particles, charge-to-mass ratio increases as aspect ratio increases. Therefore, at large aspect ratios, the needed extraction electric field decreases as seen in the following figure. For this reason increasing the aspect ratio of the particles increases in turn the Isp and the overall internal efficiency6 . A good candidate for further research are the CNTs due to their cylindrical Figure 5: Cylindrical particles’ vacuum extraction field simulations6 shape, high aspect ratio, good charge-to-mass ratio and fast charging. By choos- ing different CNT sizes to be used with variable gate potentials, the nanoFETs’ Isp range is theoretically very large compared to other electric propulsion sys- tem such as ion thrusters or hall thrusters. Similarly, the thrust-to-power varies greatly, which offers the flexibility of using the same propulsion system for mul- tiple missions or to perform unplanned trajectory changes at a low propellant expense. These are theoretically achieved while maintaining a high internal efficiency that is usually above 85%. For the following CNTs: nanoFET par- ticle1 16nm diameter, 3 µm length; nanoFET particle2 4nm diameter, 3 µm length; nanoFET particle3 1nm diameter, 3 µm length, the expected Isp and Thrust-to-Power ratio is illustrated4,5 . Figure 6: Thrust-to-power ratio for large specific impulse range4 Figure 7: Internal efficiency for large specific impulse range4 Discussion Apart from the large specific impulse range at high internal efficiency that pro- vides great flexibility to design a multitude of mission phases based on just one propulsion system and to accommodate for unforeseen scenarios, the nanoFETs have other important advantages over other electric propulsion system, such as potential longer operational lifetime, their geometric scalability and the fact that the system is highly integrated. The longer operational lifetime is due to the fact that the CNT particles or any other conductive particles are charged electro- statically and not ionized which eliminates the need for cathodes and eliminates charge exchange collisions that are the main lifetime reduction factors5,6 . However, there are still a multitude of challenges ahead until a fully functional prototype will be achieved. First of all, the experiments done so far that demon- strated particle transportation, charging and lift-off were conducted using mi- crometer size particles such a s Aluminum, Titanium and Indium. Although theoretically the CNTs can greatly increase the performance, no nano-size par- ticles have been experimentally used so far. Experimenting at the nanoscale might sometime reveal new problems that were not present at the micron level. Also, it is generally desirable that a quantitative experimental analysis is done in order to understand how a multitude of particles with different character- istics perform. In this way it could be determined what particle shows the most promise, although CNTs have a strong theoretical advantage mainly due to their charge-to-mass ratio. Another important factor to investigate is how the charging process changes as the size of the particle decreases to the several nanometers; the main concerns being conductivity and the contact area with the electrode. Furthermore, an investigation should also be conducted regard- ing the transportation liquid. So far, it is uncertain if a fully dielectric liquid is always desired over a slightly conductive liquid. Moreover, different liquids should be tested in order to experimentally understand how the viscosity of the liquid influences the space charge current5,6,7,8 . Finally, from an academic point of view it would be desirable that both the theoretical and experimental papers are published in a peer-reviewed journal. Conclusion Overall, the nanoFET propulsion system shows great promise due to its high specific impulse range and inherent scalability. Although it is a new concept, the most important processes such as particle transportation and charging have been already demonstrated. However, there are still a multitude of experiments that need to be conducted in order to fully understand the behavior of the system under a wide range of factors. Another interesting prospect for the nanoFET technology is their possible use , not only in the space industry, but also in medicine. The nanoFET technology can also be used to accelerate particles and inject them through cellular walls to deliver drugs. For these reasons, the nanoFET technology is an exciting and potentially rewarding research subject. References 1. Gohardani O, Elola CM, Elizetxea C.

How Does Internet Marketing Communication Differ?

1) How does internet marketing communication differ from traditional marketing communication? Internet marketing differs significantly from conventional marketing communications because of the digital medium used for communications. The internet and other digital media such as digital television and mobile phones enable new forms of interaction and new models for information exchange. A useful summary of the difference between theses new media and traditional media has been developed by McDonalds and Wilson they describe the 6 I’s of the e-marketing mix.The 6 I’s are useful since they highlight factors that apply to practical aspects of the internet marketing such as personalization direct response and marketing research but also strategic issues of industry restructuring and integrated channels communications. (Imran RT, 2010) * Interactivity (from push to pull) * Intelligence (market research) * Individualization (mass customization & personalization) * Integration (i nbound & outbound communications) * Industry restructuring (intermediation, disintermediation) * Independence of location (global ubiquity)Interactive marketing promotes a two way communication as compared to traditional marketing, which is usually ruled by one way communication. The difference between interactive marketing and traditional marketing are Push and pull marketing strategy. Traditional marketing strategies were based on a â€Å"push† methodology where managers were literally pushing the products onto the customers. (www. ctsocialmediaconsultant. com). Difference between internet marketing, particularly the Internet, is predominantly a ‘pull’ technology, the customer having initiated the visit to the web site.This may lead to subsequent push activities, such as sending e-mails to people who have registered their interest on the site, but the initial communication is a pull event. (www2. accaglobal. com) Interactivity is a significant feature of the ne w media, allowing a long-term dialogue to develop between the customer and the supplier. In the context of the web site, this is likely to be through e-mails, providing the customer with information and special offers for their areas of specific interest.To initiate this dialogue the web site must capture information such as e-mail address, name, age, gender and areas of interest. Example of AEC company site only collects such information for people who wish to view downloadable study material. This is too restrictive and it will probably exclude all the potential CPD customers. AEC needs to consider ways of making it easier and worthwhile for visitors to the site to register their details. There is no evidence of AEC contemplating the potential use of interactive digital TV or mobile phones to establish long-term dialogues with their customers. www2. accaglobal. com) Intelligence has also been a key feature of the internet marketing, allowing the relatively cheap collection of mark eting research data about customers’ requirements. This is routinely available from web logs and these logs need to be viewed and analyzed using appropriate software. This type of analysis is rarely available in the traditional marketing. For example, AEC does not know how often their training course catalogue is accessed and which pages are looked at. It only knows which training courses are eventually bought.With the internet marketing the company is able to see which services and products are accessed and also to measure how many of these are turned into actual sales. This conversion rate may be an important source of information. For example, why are certain web pages often visited but few sales result is it a problem with the web page? Is it a problem with the product? An understanding of visit patterns allows the organization to focus on particular products and services. This analysis should already be available to AEC but there is no evidence that it uses it or is even aware of it. www2. accaglobal. com) Internet marketing also permits the marketing to be individualized, geared to a particular market segment, company or individual person. In the context of AEC this individualization could be achieved in at least two ways to reflect clear market segmentation. AEC has recently won a contract to supply professional accountancy training to a global accounting company. All students working for this company will now be trained by AEC in one of its worldwide centers. At present this company and its students will be served hrough a generic web site. However, the flexibility of the new media means that a site could be developed specifically for this requirement. The whole site would be geared, and branded, towards the requirements of the global 21 accounting company. Information that is irrelevant to that customer, such as CPD, would not appear on the site. This individualized approach should strengthen the relationship with the customer. Similarly, indiv iduals may have their own access customized as a result of the profile that they have entered.So, for example, if they have already stated that they are currently sitting the professional stage of an examination scheme then only information relevant to that stage will be presented to them when they log in. This is an example of the principle of mass customization that was only available in a limited form in the traditional media. AEC does not exploit this at present, but uses a generic web site that looks and feels the same, whoever the user is. (www2. accaglobal. com) Finally, internet marketing provides independence of location allowing the company to move into geographical areas that would have been unreachable before.The Internet effectively provides a worldwide market that is open 24 hours per day, seven days per week. It is difficult to think of any traditional marketing which would have permitted this global reach so cheaply. Furthermore, the web site might also omit the actu al physical location of the company because there is no requirement for information to be physically sent to an address. It should also be impossible for the potential customer to gauge the size of the supplying company. AEC has exploited this to some extent as it serves a world-wide market from no clear geographical centre.However, the absence of on-line course booking means that certain physical contact details have to be provided and these might undermine the global perspective. (www2. accaglobal. com) Online marketing integrates creative and technical aspects of the internet. One can put his presence online with interactivity having proper attention to their services and products. Online marketing is not just ‘having a website' or ‘building a website' or ‘promoting a website'. Online marketing is different from off-line marketing, following characteristics differentiate them:One-to-one versus one-to-many One-to-one versus one-to-many approach, the targeted user is typically browsing the Internet on their own, and the marketing messages reach them personally. This can be very clearly seen in search marketing, where the users find advertisements targeted to specific keywords that the users asked for (www. homeimprovementsmarketing. com). In Traditional marketing, the medium allows for only one way communication. The same marketing content is used for suppliers as well as customers mostly.On the other hand when the medium is internet, the model allows for many to many marketing communications. When internet is used as a medium, the customers and companies can interact with the medium directly as well as the other customers and companies. The customers can further add to the medium and be a part of the marketing. The communication using such a model is not just from sender to receiver but in all possible directions. Traditional push communications are one-to-many, from one company to many customers, often the same message to different segment and often poorly targeted.With digital media one-to-same reaching a niche or micro-segment becomes more practical e-marketers can afford to tailor and target their message to different segment through providing different site content or e-mail for different audiences through mass customization and personalization. Potentially digital media provide a one-to-many communication from company to customer rather than one-to-many communication from company to customer that is traditional in marketing using the mass media, such as newspapers or television. (Chaffey, Johnston page 351) Customers can compare onlineInternet marketing allows businesses as well as the customers to co create a highly effective network worldwide, and dramatically increase the client trafficking. Compared traditional marketing communication, the Internet marketing makes it easier for buyers to compare two items side-by-side (online-business-journey. com). Before making a purchase, today’s customers can get complete the detailed of product information, the products information are very details stated on the web as compared to the retail store, the salesperson will not remember all the details about the products.It is easy for the customers to have the information on the internet. They do not need to go to the store just for searching for the product details. Inventory is the level of stocks, this is for the customers who just want to view the product, and they will not buy instantly. For the order status which means â€Å"active orders† are orders which you paid for, whether still in processing or previously sent out (support. chinavasion. com). This facility cannot be offered in offline marketing because in offline marketing the buyer would have to go to the shop and buy the things physically.Online marketing saves unnecessary transport expenses and saves time too. (www. dwsmg. com) Get the feedback of your target market in a snap Another communication of internet marketing is that you can get the feedback of your target market in a snap. They can comment and ask questions about your post real quick. That way, you can communicate with your customers faster and the sooner that you convince them to purchase the product or service that you are promoting, the better. What is amazing about internet marketing is that it can be very interactive.When you air a commercial, you need to conduct a survey to find out what your audience has to say about it. Online, it is so much simpler because you can skip the survey procedure and still get an honest feedback anyway. Never underestimate the marketing power of word of mouth. Traditionally, it was said to be even more effective than actually launching an advertisement. That is because people would rather hear a recommendation from a friend or someone who has used the product rather than an advertiser. www. techie-buzz. com) Demographics targeting versus behavioral targeting Off-line marketers typically segment their mar kets according to age group, sex, geography, and other general factors. Online marketers have the luxury of targeting by activity. This is a deeper form of targeting, since the advertiser knows that the target audience is people who do a certain activity instead of just expecting that a certain group of people will like their new product or service (www. homeimprovementsmarketing. com).The  internal  characteristics  of  the  internet  marketing  makes  it  very  different  from traditional marketing , for an example  the  information can be transferred easily, it can be addressed directly, constant availability, integration, flexibility, individuality, interactivity, all these factors that are inherent for internet marketing can be used by companies to shape customer relationships When the traditional marketing tools are used the flow of information is not easy and the customer as well as the companies have to follow some proper channels.Consistency, valid ity and access to information are necessary in marketing which the traditional marketing channel often lacks (Sundas48, 2011) Since exposure, response and overall efficiency of Internet media is easy to track compared to traditional â€Å"off-line† media, through the use of web analytics for instance, Internet marketing can offer a greater sense of accountability for advertisers. Marketers and their clients are becoming aware of the need to measure the collaborative effects of marketing References Chaffey, Johnston, 2006.Internet marketing strategy, implementation and pratice 3th edition, Prentice Hall Difference Between Online and Offline Marketing, (2008), Available from: http://www. dwsmg. com/difference-between-online-and-offline-marketing. html [Accessed on 27 June 2011] Is  Online Marketing More  Effective  for  Organizations  Today  (page 22) by Sundas48, (2011) Available from: http://www. scribd. com/doc/54220673/18/Communication [Accessed on 27 June 2011] Professional Level – Essentials Module, Paper P3, (2008) Business Analysis Available from: http://www2. ccaglobal. com/pubs/students/acca/exams/p3/past_papers/p3_2008_jun_a. pdf (page 21) [Accessed on 27 June 2011] How does internet marketing communication differ from traditional marketing communication?

Nurse Mentoring Concept Analysis Response - 996 Words

Nurse Mentoring Concept Analysis Response Introduction According to McEwen and Wills, concepts in the nursing profession are words that describe a variable of nursing practice (2014, pg. 50). Concepts, once defined, are used in research to test hypotheses that will increase knowledge and theory development. However, concept definitions change with time and context. Therefore, it is important to thoroughly and succinctly define concepts within an analysis for a meaningful application. Mentoring in nursing practice has been thought of as a beneficial way of increasing nursing knowledge for several decades (Stewart Krueger, 1996, pg. 311). However, the concept of mentoring had not been defined or analyzed, which made researching its effectiveness useless. This concept analysis of mentoring in nursing practice shows that mentoring can be mutually beneficial for a mentor, protà ©gà ©, and nursing practice. However, further research on this concept is necessary to determine the broader application to nursing as a scientific discipline. Method of Analysis In the concept analysis of mentoring, Stewart and Krueger used the evolutionary method by Rodgers (Stewart Krueger, 1996, pg. 312). This method involves multiple steps of analysis that are often occurring concurrently rather than completing a step after one is completed. The benefit of this method is that it has clear phases in the analytical process but is time efficient because steps are occurring at the same time.
