Rhodium Catalysts in the Oxidation of CO by O<sub>2</sub> and NO: Shape, Composition, and Hot Electron Generation

Description: It is well known that the activity, selectivity, and deactivation behavior of heterogeneous catalysts are strongly affected by a wide variety of parameters, including but not limited to nanoparticle size, shape, composition, support, pretreatment conditions, oxidation state, and electronic state. Enormous effort has been expended in an attempt to understand the role of these factors on catalytic behavior, but much still remains to be discovered. In this work, we have focused on deepening the pr… more

The Reaction and Growth of Uranium Dioxide-Aluminum Fuel Plates and Compacts

Description: The reaction of dispersed Uo/sub 2/ in an aluminum matrix in pressed compacts and fuel plates was studied at 500 to 600 deg C. Correlation of reaction with the accompanying volume increases was rmde and a growth mechanism proposed. Reaction rates and preducts are given as functions of UO/sub 2/ concentration temperature, and time. (W.D.M.)

Maskless, resistless ion beam lithography

Description: As the dimensions of semiconductor devices are scaled down, in order to achieve higher levels of integration, optical lithography will no longer be sufficient for the needs of the semiconductor industry. Alternative next-generation lithography (NGL) approaches, such as extreme ultra-violet (EUV), X-ray, electron-beam, and ion projection lithography face some challenging issues with complicated mask technology and low throughput. Among the four major alternative NGL approaches, ion beam lithogra… more

Interfacial and near interfacial crack growth phenomena in metal bonded alumina

Description: Metal/ceramic interfaces can be found in many engineering applications including microelectronic packaging, multi-layered films, coatings, joints, and composite materials. In order to design reliable engineering systems that contain metal/ceramic interfaces, a comprehensive understanding of interfacial and near interfacial failure mechanisms is necessary.

Self- and zinc diffusion in gallium antimonide

Description: The technological age has in large part been driven by the applications of semiconductors, and most notably by silicon. Our lives have been thoroughly changed by devices using the broad range of semiconductor technology developed over the past forty years. Much of the technological development has its foundation in research carried out on the different semiconductors whose properties can be exploited to make transistors, lasers, and many other devices. While the technological focus has largely … more

A Fuzzy Logic Framework for Integrating Multiple Learned Models

Description: The Artificial Intelligence field of Integrating Multiple Learned Models (IMLM) explores ways to combine results from sets of trained programs. Aroclor Interpretation is an ill-conditioned problem in which trained programs must operate in scenarios outside their training ranges because it is intractable to train them completely. Consequently, they fail in ways related to the scenarios. We developed a general-purpose IMLM solution, the Combiner, and applied it to Aroclor Interpretation. The Comb… more

The Causes of Revolution: A Case Study of Iranian Revolution of 1978-79

Description: This study investigates the causes of the Iranian revolution of 1978-79. To this end, the different theories of revolution are reviewed in Chapter One. Chapter Two provides a discussion of the historical background of the country and the role the clergy played in shaping its political development. Socioeconomic and political factors which contributed to the outbreak of this revolution are examined in the following two chapters. Finally, an attempt is made to draw some conclusions on whether exi… more

The Influence of Psychological Stress and Personality upon Athletic Performance of Intercollegiate Tennis Players

Description: This investigation was designed to study coach and self-appraised groupings of intercollegiate tennis players who yield to stress and withstand stress and to determine if personality differences existed between groups. Subjects were 75 intercollegiate tennis players from Texas. A stress inventory and the Cattell Sixteen Personality Factor Questionnaire were instruments utilized in the study. Data were subjected to hierarchical profile-groupings, three-way analyses of variance, and a correlation… more

Rheumatoid Arthritis: A Follow-Up Assessment of Physical Functioning Abilities After Treatment in a Comprehensive Environmental Control Unit

Description: Two instruments were developed and administered to fifteen female and three male rheumatoid arthritics (mean age 44) previously hospitalized for allergy treatment by ecological methods. The Physical Functioning Ability Scale assessed functional capacity according to common daily activities, and the Rehabilitation Questionnaire surveyed adjustment problems subjects encountered after hospital discharge. ANOVA was performed on the functionality scale comparing dimensions of dependence, pain, and d… more

A Preliminary Study of the Systemic Problems Underlying U.S.-East European Trade Relations

Description: This study hypothesizes that the major barriers to expanded trade between the U.S. and Eastern Europe are systemic in nature. Using this approach, each political/ economic system is examined in an attempt to define the obstacles to foreign trade expansion, to describe the most important systemic and political factors at work, and to demonstrate how they have determined and will continue to shape the economic relationships between the U.S. and the countries of Eastern Europe. A final synthesis p… more
