{"title":"Novel Graphitic Structures by Design","authors":"J. Phillips, Z. Leseman, J. Cordaro, C. Luhrs, M. Al-Haik","doi":"10.1115/IMECE2007-42977","DOIUrl":"https://doi.org/10.1115/IMECE2007-42977","url":null,"abstract":"Graphitic Structures by Design (GSD) is a novel technology for growing graphite in precise patterns from the nano to the macroscale, rapidly (>1 layer/sec), at low temperatures (ca. 500°C), and in a single step using ordinary laboratory equipment. The GSD process consists of exposing particular metals (Ni, Pd, Pt, Co), which act as ‘templates’, to a fuel rich combustion environment. As an example, we have thoroughly characterized graphite growth on nickel in a mixture of ethylene and oxygen (O2 /C2 H4 ratio<3), and found that it grows in a geometry remarkably consistent with the shape of the metal template at a rate of the order one graphene layer/second at temperatures between about 500 and 700°C. Graphite structures created with GSD to date include two dimensional ‘screens’ that are inches in extent, yet are composed of micron scale squares graphite foam, hollow nanoparticles, and micron scale particles. All alternative technologies for graphite growth require specialty equipment, such as 2000 °C + ovens, and multiple steps. The alternatives are also not suited for a wide variety of pattern growth in either two or three dimensions. We propose to change focus from demonstrating GSD to determination of the mechanism of graphite growth. GSD could meet a number of recognized technological needs for future generation integrated circuits (IC). Precise patterns of oriented graphite are envisioned as: i) replacements of carbon fibers as structural elements in some aerospace and transport applications, ii) as heat conductive pathways aiding thermal management in ICs iii) as electrical conduits in ICs, iv) as the basic elements of nano-scale logic circuits. GSD graphite is arguably superior to the older and more broadly studied carbon nanotubes technology for all these IC applications for many reasons: only GSD be grown in any pattern on any surface, GSD is far cleaner (no metal residue in the graphite structure, in contrast to nanotubes), GSD structures can be formed consistently and cheaply, at low temperature, and only GSD can be readily grown into large designed macrostructures required for some heat transfer applications.Copyright © 2007 by ASME","PeriodicalId":315415,"journal":{"name":"2008 GSW Proceedings","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129753003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PC have a frequency bandgap where light is forbidden to propagate. This bandgap is strongly tied to the microstructure of the photonic crystal. Three-dimensional Tungsten photonic crystal in a Lincoln-log microstructure has been suggested as a strong alternative filter in photo voltaic cells with significantly high power efficiency. Mechanical characterization of Tungsten PC can be performed using means of micro-indentation. Here we present a three dimensional finite element simulation of the structural response of a Tungsten photonic crystal under micro-indentation load. Stresses developed in the PC can be used to quantify the level of damage in the crystal. We compare our simulation results with the experimental observations of a Vickers micro-indentation of Tungsten PC. The FE model was proven able to simulate the mechanical response of the PC with a good accuracy. The calibrated FE model can be further used to realize the mechanical behavior of PC under different thermal and mechanical stresses when used as filters in photo voltaic cells.","PeriodicalId":315415,"journal":{"name":"2008 GSW Proceedings","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125433640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The course, designed for the undergraduate junior level, was a two-semester course for a total of four credits, and it took place in conjunction with a one-hour classroom lecture in mechanical engineering. A modified version of this approach, however, can easily be used at all levels of the mechanical engineering curriculum. This laboratory’s development process began by writing a successful proposal for outside funding in order to create a hands-on teaching laboratory. A two-semester long, open-ended project was utilized, a process which required the students to come up with creative approaches to problem solving. Consequently, a full-cycle learning experience took place. The students began with the development of an initial idea, continued on through the design and construction of a working prototype (including both system and measurement sensors on prototyping boards in ELVIS), and concluded by conducting a feasibility study, which involved writing a report and giving a presentation. Currently, the ELVIS system is used extensively in many instructional electrical engineering laboratories. Its application within mechanical engineering programs, however, required the development of completely new experiments involving newly designed software, which had to be developed and built in-house.","PeriodicalId":315415,"journal":{"name":"2008 GSW Proceedings","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124511572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The baseline design is the Optical Network Research Laboratory, a telecommunications network used by the College of Technology and the AT&T Technology Laboratory for training and research. The project uses technology standards in place today and planning for future technology being discussed, researched and commercialized. The project is divided in two phases: the equipment familiarization phase or the research phase and the design phase. The first phase mainly involves extensive research as well as visitations in order to understand and learn the operations of the existing baseline network infrastructure of the college and to become familiar with all the required telecommunication hardware and software. The second phase is the project proposal or design phase of a telecommunication system using any combination of T1, T3 or SONET networks that connects five cities with a combined distance of 2766 miles and 800 total users using a ring format OC-3 carrier system that interconnects the branches of a fictitious company. Every city is to have a PBX system and telephones based on PSTN to support the users and calling features. Although the design is based on a fictitious company, the concepts of researching, developing and designing a solution provides the building blocks that are used in the real-world environment. Therefore, the research of the system design recommends different equipment to provide a better solution with performance upgrades at a lower cost for future growth.","PeriodicalId":315415,"journal":{"name":"2008 GSW Proceedings","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129380461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green or sustainable building is the practice of creating healthier and more resource-efficient models of construction, renovation, operation, maintenance, and demolition. The objective of the study is to emphasize green buildings and sustainable construction. Findings from the study indicate that the practice of green building can lead to benefits such as reduced operating costs by increasing productivity and using less energy and water; improved public and occupant health due to improved indoor air quality; and reduced environmental impacts. It has also been observed that green buildings avoid using toxic PVC plastics and products that produce greenhouse gasses thereby helping to stabilize the earth’s climate.","PeriodicalId":315415,"journal":{"name":"2008 GSW Proceedings","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130911516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
