Thermal insulation research paper

As I walked into the beautiful brick entrance of El Segundo High School the first day of freshman year, I promised myself that I would experience every opportunity available and to cherish each moment I had for thermal insulation research paper, the next four years. As the culmination of my high school education draws near, I have looked back on my time spent here and I am incredibly grateful. University Of Chicago Style? I believe it is such a privilege to attend El Segundo High and as a graduating senior, I could not have asked for a better high school experience. My name is Melanie Palmer and I have lived in El Segundo my entire life. I am proud to be a third generation El Segundo High School graduate as my grandfather, Bill Dornblaser graduated with the insulation research, class of 1951 and was on the 1952 Olympic Water Polo Team. My mother, Tina Dornblaser Palmer, graduated with the ESHS class of 1981. I am the oldest child in my family of seven and help questions, each of my four siblings attend El Segundo public schools. Our family is very close and with so many people, each day is insulation research paper eventful. Of Chicago Style? When I was twelve years old, my mother went back to work full-time so that her and my father could continue to support our family. As a result, I became part-time mom to my very young siblings. Thermal Research? In the summertime, you could see all five of us sitting at the beach shuttle stop or walking to questions dissertations, the plunge on a daily basis. I had always been very mature, but with the sudden duty of being responsible for myself and four other children under the age of nine, my maturity level greatly increased. I learned to be very dependable and paper, self-sufficient for interview questions dissertations, the sake of my family. That experience helped shape the person that I am today and thermal insulation research paper, as a result, I feel that while in college, and throughout my life, I will use these skills to become very successful. I grew up playing community sports such as soccer and softball, but in the fifth grade, I discovered volleyball. Review Essay? I instantly fell in love with the insulation paper, sport and essays, continued playing on various club teams for seven years. As a freshman, I was the starting setter for the Varsity team. Thermal Research? This was a huge goal of mine, and interview, I consider it to be one of my greatest accomplishments. I was chosen to be the captain of the team as a sophomore, and continued to thermal research, lead the team as captain junior and senior year. Our team was very successful as we made it to the CIF play-offs for three years. I was awarded Most-Improved as a sophomore, and Most Valuable Player my junior and senior years. I was also awarded All-League Team honors all four years and attended the South Bay Sportsmanship Conference for two years. As a junior, our team did tremendously well in analytical history, the CIF semi-finals. Following the season, I was awarded All- CIF team honors. Not only did I love the physical activity, but I enjoyed the competition. Volleyball motivated me to better myself; it tested my leadership, teamwork, and insulation paper, management skills. As stated previously, I wanted my high school experience to be one where I was involved in as much as possible. In addition to volleyball, I have been a member of the Spanish Club for four years, and of chicago essay, am currently the thermal insulation research paper, President. One of essay lightning, my greatest experiences in high school was the trip to Spain that I went on with the Spanish Club during Spring Break of 2007. Before I signed up, I discussed the possibility of insulation paper, going on this trip with my mom; she agreed that I could go, as long as I paid for it myself. I instantly became motivated to raise the money and would do so by any means possible. My creative juices started flowing and I created a duct-tape wallet business in which I made one-of-a-kind wallets out essays on influence, of the handy utility adhesive in various colors. I sold my creations at the Hometown Fair and they were an instant success. I continued making custom wallets for kids at research school and dissertations, people around town, and with the addition of babysitting profits, I made enough money to go on insulation research paper, the trip. By paying for the vacation on my own, I appreciated each and every day in Spain. I also learned important life skills such as the value of essay lightning, money and the rewards that come with my savings. That week was the greatest experience of my life thus far, and as a result, I have many aspirations to thermal, travel the world. My leadership skills were acknowledged when I was chosen to be a part of the Link Crew program that was implemented on essay, campus this year. The Link Crew is research a select group of juniors and seniors chosen to lead small groups of freshmen through their first year of high school with academic and social gatherings, beginning with Freshman Orientation. I am also a member of the Wellness Committee, which is a program that helps to analytical rubric, increase healthy lifestyles amongst the students at our school. Furthermore, I have been a part of many enjoyable activities around school such as Archbearing, Homecoming float building, and was honored to be chosen Senior Homecoming Princess. In addition to school activities, I am a very hard-working student. Insulation Research Paper? I have received the Principal’s Honor Roll for four years, have taken Honors courses, and challenged myself with four Advanced Placement classes. To further my education, I plan to attend California Lutheran University in Thousand Oaks, CA. I will major in Mass Communications, as my career goal is to work in the magazine industry. This passion of help, mine began when I was ten; I absolutely loved my subscriptions to young adult magazines. I would read them cover to cover; my favorite part being the Letter from the thermal paper, Editor. I would imagine myself in that position and read the letters thinking about what I would write as the Editor of the help questions dissertations, magazine. At sixteen, I was chosen as an thermal insulation paper, “It Girl” for Teen Vogue and volunteered at the Fashion Live Fashion Show for two years. In addition, I have participated in advertising focus groups for major fashion brands. This experience allowed me to have a small taste of the industry; however, I want more. I continue to essay style, have high aspirations and am motivated to thermal insulation research, learn by working diligently throughout college to essay, achieve my goals. I now look back on that first day of freshman year where I went through the doors with the words “Enter to learn, go forth for thermal insulation research, service” above my head. As I exit for the last time this June, I will leave knowing that I did just that. I learned so much; not only in the classroom, but through the experiences I had as a student at El Segundo High. I will soon be somewhere new, but I will continue to “go forth for service” each day.

WEST LAFAYETTE, Ind. Thermal Insulation. - Researchers are making progress in developing rechargeable batteries based on carter potassium, a potential alternative to lithium that’s less expensive and far more plentiful, and also have shown how to derive carbon for battery electrodes from old tires. “With the growth of thermal paper, rechargeable batteries for analytical history essay electronic devices, electric vehicles and thermal insulation paper, power grid applications, there has been growing concern about the university of chicago, sustainability and cost of lithium,” said Vilas G. Pol, an associate professor in the Davidson School of research paper, Chemical Engineering at Purdue University. “In the last decade, there has been rapid progress in comparing photosynthesis, the investigation of metal-ion batteries beyond lithium, such as sodium and potassium.” Because of its greater abundance and insulation paper, lower cost, potassium shows promise for large-scale electricity storage on the power grid. “The intermittent energy generated from solar and wind requires new energy storage systems for the grid,” Pol said. “However, the essays on influence, limited global availability of lithium resources and high cost of extraction hinder the application of insulation research, lithium-ion batteries for such large-scale energy storage. This demands alternative energy storage devices that are based on earth-abundant elements.” Potassium is about eight times more abundant than lithium and one-tenth the cost, he said. Three research papers on the potassium-ion battery work were published this month, in collaborations with the U.S. Department of Energy’s Oak Ridge National Laboratory and National Cheng Kung University in Taiwan.  “We initiated this program almost a year ago, and there are not many groups in the world working on potassium-ion batteries,” Pol said. The three papers were published in ACS Applied Materials and Interfaces , Chemical Communications and the Journal of the Electrochemical Society . In one paper, the researchers describe a new design using carbon nanofibers as the anode. Batteries have two electrodes, called an essay style, anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite. Lithium ions are contained in a liquid called an insulation paper, electrolyte, and interview questions dissertations, these ions are stored in the anode during recharging. New findings showed that batteries with anodes made of carbon nanofibers are promising. Insulation Research. The paper is available at DOI: 10.1021/acsami.7b02476. “The carbon nanofibers demonstrate great potential as an anode material for potassium-ion batteries,” Pol said. History Essay Rubric. “We studied batteries for up to 1,900 charge-discharge cycles, which is pretty remarkable.”  The carbon nanofibers were created with a process called electrospinning, where high voltage is used to pull a charged polymeric solution between two electrodes, and the polymer fibers are then turned into carbon fibers. The batteries showed “reasonable capacity” after being charged for only six minutes, having a capacity of 110 milliamp hours per gram, one-third of the capacity achieved after 10 hours of research paper, conventional lithium ion battery charging, he said. “Usually, you would get very limited capacity after only six minutes because that’s not enough time to essay lightning charge a conventional battery,” Pol said. “However, carbon nanofibers allow the battery to be charged much faster because the ions only thermal have to travel a very short distance. Essays. The typical cellphone battery contains particles that are 15-20 micrometers in diameter, which is paper a much greater distance then this fiber-like architecture, and that’s why it takes two to three hours to charge your phone.” The design eliminates the need for a “binder,” or a polymer gel to hold graphite powder in place. Essay Lightning. A nanofiber network instead holds the potassium particles, an approach that could decrease the battery’s weight. The nanofibers were “oxygen functionalized,” meaning oxygen molecules are attached to their surface, reducing further corrosion from the acidic electrolyte. They also were functionalized with nitrogen molecules to increase electrical conductivity.  In a second paper, plate-like structures of ceramic, electrically conductive materials called MXenes were used to create a new type of insulation research paper, potassium-ion battery. During the charging process, ions are said to intercalate, meaning they are forced by electric current to move between layers of the carbon anode, building up a charge. Because potassium has a larger atomic diameter than lithium, it is rubric more difficult for thermal paper it to intercalate. However, MXenes may allow researchers to sidestep this obstacle. The researchers are the first to report findings on the performance of plate-like electrode structures made of an MXene called titanium carbonitride. “Usually ceramics are not electrochemically active, but MXenes are because you have a brick-like structure, and essay lightning, the ions can be inserted between these bricks during charging,” Pol said. Paper. “We have shown that potassium does charge and discharge effectively if you tune the material’s morphology and structure.” Using potassium also could bring less expensive batteries by replacing copper with aluminum as a “current collector” for essays anodes. Lithium-ion batteries require copper for the purpose, whereas aluminum can be used instead in the potassium-ion batteries. In a third paper, carbon was derived from thermal paper waste tires to create carbon anodes for a potassium-ion battery. The tires were reduced to a form of carbon called hard carbon through a chemical-treatment process followed by a procedure called pyrolysis. The paper is photosynthesis essay available at insulation DOI: 10.1149/2.1391706jes. “The recycling of waste-tire rubber is analytical of critical importance since the discarded tires pose serious environmental and health hazards to our society,” Pol said. “Here, we report a new application for hard-carbon materials derived from waste tires as anodes in potassium-ion batteries.” In hard carbon, carbon layers are randomly arranged, and insulation, this disordered arrangement facilitates intercalation of potassium ions. “This study demonstrates how material engineering of carbon can address some of the issues resulting from bulkier potassium-ion intercalation, and may bring possible strategies to improve performance of these batteries in the future,” he said. Purdue chemical engineering graduate student Ryan A. Adams led much of the research.   His research is co-directed by Vilas Pol and Arvind Varma, R. Games Slayter Distinguished Professor of Chemical Engineering.  A full listing of the papers’ co-authors is comparing photosynthesis respiration available in the abstracts.

The effect of oxygen functionalization on thermal research paper K-ion carbon anode performance was tested for the first time via plasma oxidation of prepared carbon nanofibers. The produced materials exhibited exceptional cycling stability through the amorphous carbon structuring and 1-dimensional architecture accommodating significant material expansion upon K + intercalation, resulting in a stable capacity of 170 mAh g -1 after 1900 cycles at 1C rate for N-rich carbon nanofibers. Analytical History Rubric. Excellent rate performance of 110 mAh g -1 at 10C rate, as compared to 230 mAh g -1 at C/10 rate, resulted from the pseudo-capacitance K ion surface storage mechanism and thermal research paper, the increased K + solid diffusion coefficient in coach essay, carbon nanofibers as compared to thermal paper graphite. Plasma oxidation treatment augmented surface pseudo-capacitive storage of K + by comparing essay, oxygen functionalities, but increased material charge transfer resistance as compared to N-rich carbon fibers.
