Perovskite Electro throttle for carbonic acid gas Reduction DesignTheoretical design of efficient perovskite electro accelerator pedal for CO2 drop-offSummaryThis project aims to engineer perovskite materials as efficient electro accelerator pedals for CO2 to fuel conversion. Perovskite are appealing tidy sumdidates because of their wide ranging and complex electronic structures. There is a scope to break some of the limitations of metallic catalysts to come up with new efficient electro catalyst. The endless varieties of electronic halalties oxides show are truly astounding. We would like to pursuit this big materials space systematically for possible catalyst with improved activity for CO2 reduction. However, they should also be active, stable and conductive at relevant potentials to tinge application targets. Identification and expressment of design principles for efficient oxide catalyst for CO2 reduction get out mark the scientific part of this project. Efforts to be ma de for predicting molecular(a)(a) pathway of CO2 reduction chemical reactions and develop unified try criterion like descriptors regarding these reactions. Then this knowledge to be applied for last throughput computational attend for best perovskite electrocatalysts. In this project we plan to utilize the latest simulation methodologies developed based on density useful theory (DFT) towards understanding the molecular machine of CO2 to fuel conversion on oxide surfaces. Further on, we impart explore kinetic barriers using nudged elastic band band (NEB) method to come up with possible efficient electro catalyst.Introduction and perspective on impactGlobal energy consumption will increase manifold in a some decades as outsizer fraction of world population achieves higher quality of life. This demand could be met from fossil fuels, particularly coal. However, in recent time, carbon dioxide take in the air has reached the highest (400 ppm) of the last 20 million years, causin g radical and largely unpredictable changes in the environment. Thus to maintain sustainability for human kind, it will posit invention, development, and deployment of carbon-neutral energy production at a scale larger than, the entire energy supply in modern civilization. To support high penetration of renewable energy sources such as solar and wind power it would require a commensurate increase in energy storage capacity to commix them into the electrical power grid. This is to facilitate reliability in power delivery by smoothing out the large fluctuations.Electrochemical conversion of CO2 and H2O into bland fuels is the holy grail where high density renewable energy storage and CO2 capture meet each early(a). However, no electro-catalyst known to man can catalyse this reaction efficiently. Copper (Cu) is the only metal with considerable activity, but its efficiency and selectivity for liquid fuels are far too low for practical use. ruthenium dioxide can convert CO2 to metha nol at a low overpotential, however, the process is rather unselective and ruthenium is extremely scarce. It is of utmost importance to take heed efficient electro catalyst with low over potential, high faraday efficiency and most importantly, made of earth abundant elements. Recent success obtained in photo electrocatalytic reduction of CO2 on SrTiO3 surfaces and electrocatalytic reduction of the same on Lanthanum Strontium Cuprate perovskite leads us towards selecting oxides especially perovskite as the most promising class of materials to study.The potential cast space of (mixed metal at A and B site) perovskite materials is very large, thus experimentally testing all compounds is not practically feasible, but has to be contract down through computational back. Simulation science has taken up a key role in development of new energy materials in the last couple of years, through computation of materials properties, which are difficult to measure experimentally. Development in computer power has enabled large-scale materials screening and design at atomistic scale. Within catalyst design, simulations can identify restrictions on catalyst activity and selectivity caused by scaling laws, and these laws enable efficient prediction of activity or selectivity for possible new catalysts.BackgroundHori did seminal work on electrochemical reduction of CO2 on pure metals. Cu is the only metal that does not desorb CO and can uniquely reduce CO2 to significant quantities of hydrocarbons (mainly CH4 and C2H4). Reduction of CO2 on Cu is accompanied with a very high over-potential that hinders this reaction from being energy efficient. Recently, a mechanism that explains coppers unique ability in reducing CO2 to hydrocarbons and the origin of the high over-potential for the reduction of CO2 was set by DFT calculations in conjunction with computational hydrogen electrode (CHE) model. Since electrochemical CO2 reduction to methane is an eight electron-proton transfer st ep that has seven fairs, finding the best catalyst in principle demands understanding of a seven-dimensional molecule surface interaction space. Fortunately, the binding energies of carbon bounded species and oxygen bounded species scale with the binding energies of CO and OH, respectively. These correlations reduce the dimensionality to two binding energies but make it difficult to change the binding energies independently. Based on different reaction pathways and scaling relations Peterson and co-workers constructed volcano plots for different metals. It was shown that regardless of the reaction pathway, changing the metal surface marginally changes the over-potential. This helped to move the focus on other class of catalysts e,g, rutile oxides (Ru/Ir/Ti) can turn the conversion of CO2 to alcohols. However, very little is known about the reduction of CO2 to alcohols on oxide electrocatalysts. As the binding energies of OH/CO vary much wide on oxides than metals, it is possible to have different pathways and thermodynamical limiting steps on oxide surfaces than metallic whizs. That makes template based computational search much more(prenominal) challenging, at the same time opening up possibilities of adsorbate-surface binding energies away from the established scaling laws.In general, there are three criteria that should be carry out by a newly proposed catalyst materialThe catalyst should have high selectivity towards desired productIt should have high energy efficiency, i.e. low reduction over-potentialIt should be stable at potentials of interest so that the activity does not degrade over timeIt should have sufficient electronic/polaronic conductivity look for planFor the thermodynamic pathway of the reactions, computational hydrogen electrode model will be followed to calculate the potential dependent reaction free energies from density functional theory based calculations using BEEF-vdW functional and PAW method as implemented in VASP. Correction s for zero point energy, heat capacity, entropic contribution and other energy correction for free molecules will be taken into account. Usage of BEEF-vdW functional will enable the estimation of errors in first principles calculations and describe proper long range van der Waals interaction between adsorbates and surfaces. Statistical tools will be used to calculate corrections from vibrational modes of the adsorbates. In addition, to describe in good order the electronic structure of late transition and rare-earth metals, Hubbard U correction method will be employed as and when required. To know atomic structure of the catalyst surface, which is key to these calculations, potential dependent surface Pourbaix diagrams will be constructed. Kinetic barriers for individual reaction steps will be searched with the climbing image nudged elastic band (CI-NEB) method. This method lets us find saddle points and minimum energy paths between two atomic configurations and works by optimizing a number of intermediate images along the reaction path.Using this methodology to study CO2 reduction over a handful of well-known perovskite materials, we will be able to establish activity descriptors for favorable catalysts. Through BrnstedEvansPolanyi relation between the activation energy and the reaction energy extends scaling laws to kinetic barriers as well. Using thermodynamic and kinetic scaling laws, it will be feasible to define most critical descriptors of the many electron reactions. These descriptors along with selectivity based parameters (e.g. suppressed hydrogen evolution) will be used to screen through a really large phase space of perovskite structures constructed in a 2x2x2 supercell (40 atoms) by using a large number of different elements in A/B or anion site as well as vacancies which are common in many perovskite materials. fundamental fraction of these hypothetical structures will be discarded through simple rules like oxidation number sum, Goldsteins rule and Valence Bond models. In the screening process, the stability of possible structures are assessed using an accurate scheme of comparing the total energy of each compound to a pool of reservoir systems using a linear programming algorithm, to determine whether the material is stable or not. The further level of screening will include looking for materials with baseborn or no bandgap using GLLB-sc functional. This is a crude approximation for screening purpose. For few selected structures, other conduction mechanism such as quantum tunneling or polaron hopping will be studied in more detail using Marcus theory for polaron hopping and non-equilibrium Green function based transport simulation.Even with the large reduction in search space through simple rule based screening, it will be impossible to perform DFT calculation for all of the possible structure. A genic algorithm based search will enable us to effectively get the fittest candidates with existing computational resource s. The parameters for the fit function will be homogeneous as discussed above. Concepts of mutation and crossover will be used for quick searching.The project will be carried out in collaboration with experimentalist from DTU Energy alteration (Prof. Nini Pryds and his group) and DTU Physics (Prof. Ib Chorkendorff and group). This will enable rapid experimental validation of predicted materials as effective CO2 reduction electrocatalyst.Work package and milestonesWP1 Establish reaction mechanism (Jan 2015 Aug 2015)1.1 Calculate atomistic structure of SrTiO3 and NaNbO3 (100) and (110) surfaces from surface Pourbaix diagram1.2 Study wide variety adsorbates to confirm reaction pathway to alkane and alcohols1.3 Estimate kinetic barriers for the reaction pathsWP2 Search for Descriptor (Sept 2015 Feb 2016)2.1 Calculate thermodynamic and kinetic barrier for CO2 reduction reactions for larger number (50) of well-known perovskite.2.2 Study these barriers for identifying best descriptors for the reactions2.3 Do micro-kinetic modelling of the system considering different final products both carbonaceous and hydrogen based of the descriptors of reactions, to define region of selectivity and low over-potential exigency.WP2 High throughput computing based catalyst search and validation (Mar 2015 Dec 2016)3.1 Setup Computational infrastructure (e.g. software framework working in unison) required for screening methodology over billions of structures.

Applications have also been made for another 20 million cpu hours under the European supercomputing program PRACE.Scientific disseminationThe fundamental insight developed, catalyst predicted and validated throughout this project will generate utmost interest in the catalysis for sustainable energy field internationally. Thus findings will be published in peer-reviewed journals with a high visibility. Such publications can be expected during 4Q of 2015 and 2016. Preliminary results will be presented at relevant conferences within the palm of electrocatalysis, computational electrochemistry and surface science. Besides contributing to fundamental insight the project is focused on specific catalyst design and it is therefore an objective that one or more paten ts will be filed for at the end of the period.

Meetings Incentives Conferences And Exhibitions In The Uk Tourism Essay

Meetings Incentives Conferences And Exhibitions In The Uk Tourism EssayConference organizing nowadays is not an blowzy task especially when taking steps to enforce warranter and risk guidance measures (Bowdin et al, 2006). Conferences that observe good health status, low risks and high security measures are the most probable places to get high subject of clients. few centers provide tourism sectors, sports and other leisure activities to its clients and all this work have to be maintained so as to attract a good number of clients (Davidson and Rogers, 2006, pp 48).The MICE sector is an organization that is based in the United realm and is geared to generate large capital in the economy. Tourism in the UK is an important sector that boosts its activities and so this calls for large amounts of capital to maintain the facilities. The tourism sector in the UK includes a lot of business travels which entails activities such as attending meetings, incentive travels, tidy sum fair s and exhibitions and also individual preference for leisure travels ( favorable, 2007, pp 18).According to Rogers (2008, pp 255), the extremum ten gathering destinations and conference business within the UK includes London, York, Glasgow, Cardiff, Newcastle, Harrogate, Edinburgh, Bournemouth, Briton Hove and lastly Perthshire. Among the top conference centers in the UK, London hosts the most number of meetings and is the top most in performance compared to the other destinations (Lawson, 2000, pp 156). Davidson and Rogers (2006, pp 50), reviewed some of the reasons as to why London is at the top in hosting MICE features. He disc everywhereed that London is centrally placed in the country and it has an easy access to travel by air and this gives the travelers an easy while when moving about. It also hosts a good number of finance sectors, banking industry, culture and arts and lastly it provides headquarters of many global companies. by from the following advantages, Golden (2007, pp 18), has detect that London is loosing a lot of valuable tourists beca drill it has been overpopulated with no space for further expansion services.The MICE sector faces a lot of challenges in the industry including the contain to improve facilities that are used in collecting data in the sector. MICE have decided to improve its facilities by involving the government in providing it with capital. The support extends to planning staffs working in the sector, improving the infrastructural facilities and finally conducting enough researches on its destinations centers so as to maximize the opportunities available in this center (Jago et al, 2003, pp 12).One of the conference centers that is nether the MICE sector is Arena and Convention Center Liverpool (ACC Liverpool). It is situated in river Mersey and it is one of the largest and top conformation convention centers in the United Kingdom. It is combined in a single venue but has multifunctional sectors in it (Jones, 200 5, pp 242). The venue has a committed staff that delays it meets the daily trains of its monthly and daily clients. According to (Jones, 2005, pp 245), the ACC Liverpool convention has environmentally friendly measures implemented, in that it releases less toxic substances in the air such as carbon dioxide and it also uses less electricity costs compared to the other centers in the United Kingdom. It is a centre that hosts many Europes exhibitions, arts and culture shows, conferences and also lives performances by prominent persons. This gives it a credit when competing with the other centers that are located in United Kingdom. Its continuous growth is focused on using more mitigation measures such as recycling its waste materials, conducting a waste management trainings for its straightaway staffs in the surrounding and concentrating on utilizing energy efficient services (Jones, 2005, pp 187).Carlsen, et al (2000, pp 245), stated that the ACC Liverpool center has collaborated wi th a nearby power station to facilitate it in attaining the above management measures. The power station (Widness power station, PDM) receives the food wastes from ACC Liverpool and converts it into a homogenous puree which is then injected in boilers. The boilers then create a steam that is used to turn the turbines thereby generating electricity from it. Hilier (2000, pp 440), also noted that the wastes from the exhibitions and conferences are sorted and recyc take into a re-use state when they are taken to the Orchid environmental.Apart from the above measures that aid ACC Liverpool, it is also observed that it has two main parts that are used for live performances. The BT convention center and Echo arena hosted over 450 live events including the Davis cup and other concerts which saw its growth and development (Carlen and Taylor, 2003, pp 18). The parts have very supportive teams that makes sure that the venues are kept clean and in a world class state so as to attract even pro minent individuals for their leisure tours and travel. They also contribute a good function in the landfill project to aid in environment conservation.ACC Liverpool also has an advantage over the other centers in that it is centrally located in the country and has an easy access from the European airport. The center has decided to maximize the potentials arrived at by its location and accessibility to Europeans that come in and out of the country. It has also enacted a honored communication system called MCI which oversees organization of all events and communications within the center.The constant increase of international services to the United Kingdom has made the ACC Liverpool to be on toes for better services and involvement in the renowned business forums for international travel and meeting industry, EIBTM, 2009. It has maintained an up to date technology services to ensure that it increases it familiarity within the city as a destination of United Kingdom. It has establishe d links with the research and innovative world by hosting homes to top world class universities, cancer and other infections research centers and finally science parks that keep up with the present technology.In the competition market, ACC Liverpool has gained a lot of popularity among the destinations of United Kingdom comparing itself to other conferences held in America, Australia and Canada. Golden (2007, pp 150), reports that it is said that it will host for the first cartridge holder, international society for the scholarships of teaching and learning (ISSOTL) which is a large conference event that have been held in other international centers for the past years. Being the first time for United Kingdom hosting such a big event in its working years, it has made super preparations in the BT convention so that the event will be at its best and in the same time taking the economy at a higher level in the economy.The management team has made efforts to increase the services it off ers to its clients thereby looking in advance to be top most destination in United Kingdom. According to Jago et al (2003, pp 12), the management has also ensured that it safeguards its clients by thoroughly maintaining health and security services at the right time. It has also enacted a better communication system that is client sensitive including providing earpieces designed to give total comfort to the crowd in conferences. It has enhanced its audio clarity in that speech can be audible and clear to the audiences attending the conferences.Liverpool has the largest number of buildings which are notably said to be important than even the cities like London in the United Kingdom. Its ware front area is in a prestigious location because it places it near known world sites such as the Great Wall of China, Taj Mahal and Stonehenge. It is also hosts the famous football club , Liverpool FC, apart from other sporting activities which includes golf courses and horse bucket along at Ha ydock park (Golden (2007, pp 19). The transportation sector is well defined and it includes the air transport, road and rail transport. It has accessible road transport and a very unfaltering rail transport which are easily available to the clients who want to travel through the region.Jones (2005, pp 242), notably stated that Liverpool has combine other international agencies in its trading operations which are responsible I conducting researches on matters such as radioactive waste management and environmental mitigation measures. The international atomic energy fashion has been supporting Liverpool preparing technical programs, presentation and promotion of the conference to other member countries in the world and finally providing financial assistance when they in a crisis.Liverpool has incorporated the system of incentive travel to its clients which is, defined by Golden (2007, pp 18), a tool that is used to motivate participants to continue increasing support to accomplish ing an organizational finale or statement mission. Carlen and Taylor (2003, pp 18), further noticed that the figure obtained from the above system was used by the conference center to numerate the impact it had on its immediate environment as a destination center. The management was in a position to calculate the total amount that was invested in the conference centers and also calculate the number of employments it created in each city where the conference centers were located.Some of the negative impacts a convention has on its destination include diverse issuances on the environment through emitting harmful carbon dioxide in the air, depositing high level of wastes from exhibitions and food just alongside the conferences creating an unhealthy environment to the clients. Another impact created on the environment includes loud noise from the aircrafts which pollutes the environment by noise pollution or depleting the ozone layer thereby threatening the lives of those living and working along those areas (Jones, 2005, pp 245) altogether the above impacts have been looked unto by the management of Liverpool and safer steps taken to ensure that the environment is conducive. They have developed use of quieter aircrafts to thin noise pollution, enrolled themselves in the international hotel environment initiatives, have adopted waste management and recycling strategies to ensure that all wastes are taken care of and do not have an effect on the clients. They have also initiated the use of more energy efficient systems, the use of better and advanced technological services such as use of emails and electronic use to reduce the waste of exhibition papers.The conventions also affect the society and community socially when the conferences are held in town and there is need for security to the clients. This will mean that the local residents near the conventions will not be in a position to move about freely as some of the areas will be branded as a no go zone for them. According to Golden (2007, pp 18), such impacts may also reduce business activities in the area including lack of shopping activities and carrying out of trade within the area vicinity.Such impacts in the community are not normally paid attention to by those in the management because they view such conferences in terms of economic contribution to the area in which the conference is cosmos held from. Those living there also benefit from such conventions when they get employed to work in the organization thus improving their living standards.ConclusionCarlen and Taylor (2003, pp 19), observed that Liverpool took the initiative to promote a positive influence to those living within the vicinity of the company. It has led to improvement of living standards to the residents there by creating job opportunities that enables them to appraise their services in the area. It also supports its staff members by incorporating them in making the organizational decision so that their needs can also be catered for as well as the needs of the clients.The need to create a good decision when selecting a location of a conference center as a destination has led to Liverpool working alongside the marketing organizations which conducts researches on it to asses an area that generate an increased conference business. It has also taken initiatives in using marketing strategies and principles with the aim of fulfilling the customers needs. completely these measures are undertaken by ACC Liverpool to ensure its business flourishes in the world as it competes with other destinations in United Kingdom.

Goblins, Imps, Brownies, Trolls, Pixies, and Bogies †Yesterday and Today :: Exploratory Essays Research Papers

Goblins, Imps, Brownies, Trolls, Pixies, and Bogies Yesterday and Today In modern day, one is not likely to encounter a goblin in ones travels, except perhaps those found scurrying later candy on Halloween night. However, goblins, as well as imps, brownies, trolls, pixies, and bogies were at a time considered as much a part of daily life as cows and chickens.(Briggs, These were the fairies, the half-natural, half supernatural beings that helped and haunted mankind throughout virtually of the world. The sparing divided these fairies worldS into two groups, the Seelie Court, those helpful to humans, and the Unseelie Court, those who were mischievous, misleading, or downright evil. At the lowest rungs of the Unseelie court, one would find the goblins. (Briggs, 357) The goblins have changed, however, since these dark times, and it is the purpose of this paper to show the phylogenesis of these monsters from chivalric fairy, to subterranean miner, to Saurons horde of mini ons, and into other various modern-day incarnations. Additionally, the cultural driving forces of feminist theology, Freudian psychology, political agendas, and technological fears will be used to explain several of the more notable goblin literary works. Finally, it will be shown how the medieval concept of the goblin, the fairy trickster, will resurface after a hundred years of exile in the form of the gremlin. The goblin as a fairy has its roots mainly in Britain, although they had counterparts in most of Europe. The French had goeblins, the Germans kobolds, the Welsh pwca (pooka), and even the Japanese had the tengu. However, the name goblin is attributed to an Italian origin. The story goes that in Florence there were two infamous houses, the Guelfs and the Gibelins. So malicious were the members of these families that mothers would rebuke unruly children that the Guelfs and the Gibelins would come to get them if they did not behave. Thus the modern words elves and goblins were born. (Latham, p. 48) The fairy goblin ranged in disposition from the truly sinister to the near-harmless trickster. An example of the nastier medieval goblins is the legend of Redcap, a vicious goblin who inhabited a deserted castle. He was described by William Henderson in Folklore of the Northern Countries as a .

Susan B. Anthony Essay -- womens suffrage feminism

The word womens liberationist can be though of in many ways. just about people can hear the word in a positive way, and think of it as a woman standing up for her genders rights. early(a) people can think of it in a negative way, as a woman who is too high strung and opinionated. The word feminist is actually a female who has opinions on the way her sex is treated. Modern feminism will be discussed, along with using some examples such as Susan B. Anthony.As to the history of feminism, the beginning will be with what is called the Feminist Revolution (Rappaport 28). This revolution began in 1837 in new York. Women banded together for the first period at an anti-slavery convention. These women were considered abolitionists after being humiliated at a conference in Britain for being unladylike. Lucretia Mott and Elizabeth Cady Stanton organized the first Womens Rights Convention in Seneca Falls, rude(a) York in 1848. This conference demanded woman suffrage, equality for wives, and the right to practice any profession they chose. Some feminists include Elizabeth Blackwell, Sojourner Truth, Emma Willard, Frances Wright, Mrs. Stanton, Ms. Mott, Mrs. Adams, and Susan B. Anthony.A brief moment should be worn-out(a) on a few of the notable women. It started with Emma Willard she opened up the door for girls to get the same education as boys. She opened schools for females only. Following her is Elizabeth Blackwell. Ms. Blackwell pushed open the doors for women to be professionals. She became the first woman doctor to earn her MD in 1849 (Archer 47). Francis Wright was a Scottish-American reformer who advocated equal education for women. She erst stated, Unless women assume the place in confederation which good sense and good feeling alike assign to them, human improvement must advance feebly. Her words gave influence to women to earn their first college education.Other than Ms. Anthony there are three very notable women Mrs. Elizabeth Cody Stanton, Mrs. Sojo urner Truth, and Mrs. John Adams. The three ladies advanced the movement so far that, without them, women would not be anywhere near the liberty of today. Mrs. Stanton began the revolution of women and also started the Womens Rights Conventions. It was at one of these conventions in 1851 that a freed black female slave named Sojourner Truth spoke. It was probably the most noteworthy speech ever remembered ... ...ovement seems to have turned on women and away from men. There is more of a fight over moral issues and less about rights. Susan B. Anthony once said, Failure is impossible. Todays suffrage efforts are continuing with her drive and now have a larger base of support. When todays suffragists converse to the House or Senate, they at least can address women as well as men in these bodies. This is what Ms. Anthony wanted to accomplish. molds CitedArcher, Jules, Breaking Barriers New York Penguin Group, 1991.Barry, Kathleen, Susan B.
