Mod silver metallization: Screen printing and ink-jet printing

Basic material efforts have proven to be very successful. Adherent and conductive films were achieved. A silver neodecanoate/bismuth 2-ethylhexanoate mixture has given the best results in both single and double layer applications. Another effort is continuing to examine the feasibility of applying metallo-organic deposition films by use of an ink jet printer. Direct line writing would result in a saving of process time and materials. So far, some well defined lines have been printed

MOD silver metallization for photovoltaics

Photovoltaic cells require back side metallization and a collector grid system on the front surface. Both front and back surface metallizations should have good adhesion, low contact resistance, low sheet resistance, long term stability, and their deposition methods should not degrade the n-p junction. Advantages and disadvantages of different deposition methods are discussed

Information retrieval from holographic interferograms: Fundamentals and problems

Holographic interferograms can contain large amounts of information about flow and temperature fields. Their information content can be very high because they can be viewed from many different directions. This multidirectionality, and fringe localization add to the information contained in the fringe pattern if diffuse illumination is used. Additional information, and increased accuracy can be obtained through the use of dual reference wave holography to add reference fringes or to effect discrete phase shift or hetrodyne interferometry. Automated analysis of fringes is possible if interferograms are of simple structure and good quality. However, in practice a large number of practical problems can arise, so that a difficult image processing task results

Metallization with generic metallo-organic inks

The use and fabrication of metallo-organic films are discussed. Metallo-organic compounds are ones in which a metal is linked to a long chain carbon ligand through a hetero atom such as O, S, N, P or As. Films formed by the thermal decomposition of these metallo-organics are called MOD films. In order that the products of decomposition contain only CO2, H2O, and in rare cases nitrogen compounds, and to avoid S containing products, the use of a set of metallo-organic compounds for ink fabrication where the linking hetero atom was oxygen was pioneered. These links were made from commercially available carboxylates, or synthesized from commonly available reagents. The processing is described and the molecular design criteria are given. The particular carboxylates or amine carboxylates selected were the octoates or neodecanoates, and they are described

Echoes: A Dance Composition and Performance

Echoes: A Dance Composition and Performance analyzes the creative process of choreographing a dance with aerial elements to convey an emotional narrative. My experiences as a theatre and dance Fine and Performing Arts Honors student at East Tennessee State University from 2013-2017, culminated with my final senior capstone project as director, choreographer, and performer of The Echoing Effect, performed February 9, 2017 at the Bud Frank Theatre. The following research of the history and development of aerial dance as an art-form created a better appreciation of the artistic field and informed how I approached the daunting task of composing expressive dance that seamlessly connected movement from the ground to the air on an aerial apparatus. Through research and practical application, I explored the world of the aerial dance choreographer, and this thesis serves as a record of my journey

Measurement of Three-dimensional Density Distributions by Holographic Interferometry and Computer Tomography

The use of holographic interferometry to measure two and threedimensional flows and the interpretation of multiple-view interferograms with computer tomography are discussed. Computational techniques developed for tomography are reviewed. Current research topics are outlined including the development of an automated fringe readout system, optimum reconstruction procedures for when an opaque test model is present in the field, and interferometry and tomography with strongly refracting fields and shocks

Modular digital holographic fringe data processing system

A software architecture suitable for reducing holographic fringe data into useful engineering data is developed and tested. The results, along with a detailed description of the proposed architecture for a Modular Digital Fringe Analysis System, are presented

Onset of convection due to horizontal laser beams

When a horizontal cw laser beam is suddenly turned on in a quiescent isothermal fluid there is a delay time t∗ during which thermal blooming is governed by absorption of radiation and thermal conduction. For t≳t∗, free convection becomes a significant factor. t∗ is determined by an approximate quasisteady hydrodynamic stability analysis and is compared with existing experimental data.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71189/2/APPLAB-26-6-287-1.pd
