Personal Statement Of Application For Nannomaterials

I am applying for the position of Research Associate to work with you and Professor Yves Chabal. I have applied to the position through the website of the University of Texas at Dallas as well. Fueled by the revolutionary changes brought by nanomaterials in today’s world, especially in dye-sensitized solar cells, I joined the Department of Chemistry to do research on nanotechnology while preparing to take a Master’s degree in Physics from the same university with a solid foundation in materials science, basic electronics, advanced device electronics, quantum physics, and computational physics. According to the International Energy Agency’s 2015 World Energy Outlook, a complete de-carbonization of the world’s energy system is needed for a†¦show more content†¦The following summaries of my research accomplishments, I believe, should be able to support my enthusiastic approach to bring a substantial change in the research progress in the department o f physics and materials science. I for the first time created a strong covalent amide bond between TiO2 mesoporous films and N719 by chemically modifying TiO2 with 3-aminopropyltrimethoxysilane. The dye-sensitized solar cells thus prepared were stable and more resistant to UV light, thermal stress, acid, and water when compared to traditional photoanodes. There was a dramatic preservation of the SCN ligand of N719 on the TiO2 surface for up to 6 months, which is not possible in the case of other modified photoanodes with dye attached non-covalently through electrostatic or hydrogen bonding interactions. (Langmuir, 2013, 29, 13582-13594). I extensively studied the synthesis of nanomaterials, quantum dots such as ZnS, CdS, electrodeposition of semiconductor oxide materials, preparation methods for different shapes (nanowires, nanotubes, and tree-like structures) and sizes (3-300 nm) of nanomaterials to accomplish this research work. I did research on molecular linkers to link quantum dots. In addition, I explored the charge injection dynamics from the excited dye (N719) to TiO2 semiconductor nanoparticles after chemical modification of the TiO2 nanoparticles with silane linkers using the ultrafast transient absorption

Geography Hazards And Natural Hazards - 1011 Words

QE GEOGRAPHY ASSESSMENTNT: NATURALAL HAZARDS Natural Hazards Puddles Jack R Eggen 1/1/2015 ‘A puddle is a small mass of liquid, usually water, which is formed on a surface. It can be formed by dips or imperfections on the surface.’ J R EGGEN Chapter 1 A puddle is a small mass of liquid, usually water, which is formed on a surface. It can be formed by dips or imperfections on the surface. Puddles are usually formed from rain water although technically it can be any liquid (e.g. oil puddles). They can be made naturally or by humans; purposely / accidently. They affect everything in its path even if it just a little bit although they can have larger effects like droning people and animals or sinking cars and vans. This can cause lots of problems as they might need their car or van for something important. A puddle is generally small enough for a person to step over or shallow enough to walk through, and too small to cross by a boat or raft although there is no exact proportion specifications to define wherever it is a puddle or not, although is it gets big enough some would say it was a lake or flood. Puddles are very common everywhere where it rains and are unlikely in dry places where there is little rainfall. In the UK it rains a lot of the time and our weather is often very cold and wet. This can be an inconvenience as it stop or delays our normal lives and on a much larger scale can cause major damage and lead to flooding; especially if it’s in a dent on theShow MoreRelatedThe Origins Of North America812 Words   |  4 Pagesthat shaped North America current physical geography was glaciers. Glaciers are what influence majority of the current landscape of North America today. North America also has a wide range of natural hazards that affects the region more than any other continent, due to the proximity of water and the latitude. The region also has a long history of the influences of the European settlers and help shaped the human geography. The current physical geography of North America was formed from the role thatRead MoreThe International Day For Disaster Reduction Essay1500 Words   |  6 Pagessuggests ‘that there is no such thing as a natural disaster’. Smith contends that natural hazards become disasters due to location and the vulnerability of humans through their own decision making and the lack of appropriate mitigation measures. The opinion that human decisions and actions create or exacerbate vulnerability to disaster is shared by many observers, where so called ‘natural disasters’ are seen to be the result of poorly managed risk when natural hazards take place. There is strong argumentRead MoreThe Water Systems And Landforms1012 Words   |  5 Pagesclimates and regions. In this paper, I will discuss the water systems and landforms found in Baton Rouge, Louisiana, as well as two other cities in the United States. I will explore the amount of water that comes and leaves their sy stems, as well as the natural landforms that occupy their regions. Background Throughout this paper, there are terms you will need to know. While discussing the water systems of Baton Rouge, we will discuss both precipitation and evapotranspiration. Precipitation is the processRead MoreCauses Of Natural Disasters833 Words   |  4 PagesAmong many natural disasters in this world, there are three natural things that are responsible for natural disasters. These three are earthquakes, tsunamis, and volcanos. We humans call them Natural â€Å"Disasters† because they could destroy all of us or all our homes and important things we need to survive. Without humans, they would only be called natural events because they would not have anything to destroy. Starting with the earthquakes, they have the potential to cause harm and injury, cost lovedRead MoreAcute Urbanization And The City Of Mumbai1422 Words   |  6 Pagesof natural resources and widening social equity gaps within urban areas.

Unemployment levels Essay Example For Students

Unemployment levels Essay The first two questions I asked were who and what. Here are my findings.  Robert, who preferably likes to get called Rob, He is in his 40 and married with a family. He loves his job and is very dedicated to it. He sympathises with both the victim and the offender, however in the case in Car I do believe he favours the offender and is very close to Nick. The reason I thought this is because he is the one he first told about the car theft he was involved in. He even offers Nick his office as a hang out. Rob doesnt smoke and is very moral and encourages Nick to hand himself in. Rob also encourages Nick to build bridges with his parents, as he believes this would help him make the switch, so he genially cares for Nicks well being. I think he dresses smart but causal, as this would reflect his attitude to work. I believe he is very calm and relaxed when dealing with the offender. Even though he is very sympathetic to the offender. He does understand Garys concerns and does all he can to make him feel better about the situation. At the meeting between Gary and Nick he doesnt stop Gary telling Nick what he thinks however does realise there is limits to what Gary can say to Nick. He stays calm throughout the meeting even when things get heated between Nick and Gary when others may have buckled under the tense atmosphere and this helps him make the meeting a successful one. As his main line of work is with the youth. He is very much in touch with modern popular culture and very modern thinking and this can be reflected in his appearance.  HE LOVES HIS JOB. Rob can adapt to situations well. He knows how to talk in to different people in different situations. This can be shown when he is in Garys house compared to how he talks to Nick in his office. He also knows how to get the best out of them and this is shown on how he encourages Nick and Gary to the meeting. Talks to Gary professionally and Nick more friendly. The next two questions I will ask is where and when.  Rob lives with his family in a middle-class area of suburb of Manchester. A town like Stockport or Sale. These area would reflect his laid back attitude to life i.e. drinking in bars along the canals in the summer or drives to the coast of the moors in his free time with his family. The time period is the 90s, so the music revolution in Manchester is in full swing with the emergence of bands like Oasis, Blur, The Stone Rose. Should we do the play in performance conditions this would be the music featured. He works in a rough part of the inner city of Manchester somewhere like Eastlands where people live in derelict terrace houses which unemployment levels are high. I think he is well respected in the area he works and this is reflected in the fact Nicks turns to him before he turns to anyone else. I think in the street he lives he would also be well respected and would take part activities within the street. The next question is why. Now I have found that hard to answer. This is because I found I could only answer this question whilst rehearsing. Everything Rob did I would ask, Why is he doing that? Or if he said something I would ask, Why did he say it in a certain way?  I have also did a brief report on a pervious case Rob may have worked on. Find that attached.
