Interfacial Studies of Bimetallic Corrosion in Copper/Ruthenium Systems and Silicon Surface Modification with Organic and Organometallic Chemistry

Description: To form Cu interconnects, dual-damascene techniques like chemical mechanical planarization (CMP) and post-CMP became inevitable for removing the "overburden" Cu and for planarizing the wafer surface. During the CMP processing, Cu interconnects and barrier metal layers experience different electrochemical interactions depending on the slurry composition, pH, and ohmic contact with adjacent metal layers that would set corrosion process. Ruthenium as a replacement of existing diffusion barrier lay… more

Interfacial Study of Copper Electrodeposition with the Electrochemical Quartz Crystal Microbalance (EQCM)

Description: The electrochemical quartz crystal microbalance (EQCM) has been proven an effective mean of monitoring up to nano-scale mass changes related to electrode potential variations at its surface. The principles of operation are based on the converse piezoelectric response of quartz crystals to mass variations on the crystal surface. In this work, principles and operations of the EQCM and piezo-electrodes are discussed. A conductive oxide, ruthenium oxide (RuO2) is a promising material to be used as … more

Interior Lighting Effects Inspired by Nature

Description: Developed in the study is the thesis that the lighting effects about us in nature can be adapted by the designer for use in interior environments. Because of an overemphasis in lighting practice on engineering techniques required in the design of luminous environments, there has been a neglect of much of the aesthetic requirements of such environments. While interior designers, as artists, may be sensitive to the aesthetic qualities of lighting, many of them have felt insecure in designing in a… more

Intermodal Stimulus Compounding with Ambient Odors Produces Averaging in Rats

Description: In an organism's natural environment, there are always an uncountable number of stimuli, and stimulus features, available to gain control over behavior. When these component stimuli are presented simultaneously, this new stimulus compound can occasion a previously unseen effect on behavior. Stimulus compounding is a method used to better understand how variables in stimulus features may impact the final effect on an organism's responding when presented with a stimulus compound. While stimulus c… more

Internal and External Drivers of Consumers’ Product Return Behaviors

Description: Product return is a necessary part of the exchange process between companies and customers. It accounts for approximately 16% of total sales and a reduction in retailer / manufacturer profits by 3.8% on average. However, industry data also indicates that a significant portion of products are returned for reasons other than product failure – e.g., change of mind, found a lower price elsewhere, or fraudulent and unethical reasons. Consequently, many firms (e.g., REI) have altered their generous … more

Internal Capital Market and Capital Misallocation: Evidence from Corporate Spinoffs

Description: This study investigates the importance of reduced capital misallocation in explaining the gains in corporate spinoffs. The capital misallocation hypothesis asserts that the internal capital market of a diversified firm fails to meet the needs of the relatively low growth divisions for less investment and the needs of the relatively high growth divisions for more investment. Higher differences in growth opportunities imply that more capital is misallocated. This study finds that the higher the … more

Internal-External Locus of Control in Glossolalics

Description: Internal-external locus of control was studied in relationship to the religious phenomena "glossolalia." Contrary to the main hypothesis formulated, glossolalics were found significantly more internal in locus of control than non-tongues speakers. Intercorrelations were studied between the variables of I-E, age, length of church membership, income level, educational level, and perceived control by God, for tongue-speaker and non-tongue-speaker groups. Chisquare comparisons were made between the… more

Internalizing-externalizing Psychopathology and Personality Pathology As Predictors of Treatment Rejection in Substance Users

Description: Substance use disorders (SUDs) are often comorbid with other psychopathology such as mood disorders, anxiety disorders, and personality disorders. While some research suggests individuals with comorbid psychopathology are more likely to seek substance use treatment than those with independent disorders, other studies have also shown many individuals with dual diagnoses still never seek treatment. Moreover, few studies have tried to elucidate the underlying structure of SUD treatment rejection… more
