Miniature Mass Spectrometry: Theory, Development and Applications
As mass analyzer technology has continued to improve over the last fifty years, the prospect of field-portable mass spectrometers has garnered interest from many research groups and organizations. Designing a field portable instrument entails more than the scaling down of current commercial systems. Additional considerations such as power consumption, vacuum requirements and ruggedization also play key roles. In this research, two avenues were pursued in the initial development of a portable system. First, micrometer-scale mass analyzers and other electrostatic components were fabricated using silicon on insulator-deep reactive ion etching, and tested. Second, the dimensions of an ion trap were scaled to the millimeter level and fabricated from common metals and commercially available vacuum plastics. This instrument was tested for use in ion isolation and collision induced dissociation for secondary mass spectrometry and confirmatory analyses of unknowns. In addition to portable instrumentation, miniature mass spectrometers show potential for usage in process and reaction monitoring. To this end, a commercial residual gas analyzer was used to monitor plasma deposition and cleaning inside of a chamber designed for laser ablation and soft landing-ion mobility to generate metal-main group clusters. This chamber was also equipped for multiple types of spectral analysis in order to …

Minority Stress, Spirituality and Psychological Quality of Life in a Lesbian, Gay and Bisexual Sample
Unique factors associated with the experience of spirituality and religiosity for many in lesbian, gay and bisexual (LGB) communities include minority stress. Using structural equation modeling, we examined whether minority stress mediates the relationship between spirituality and psychological quality of life (QOL). Results indicate minority stress mediates the relationship between spirituality and psychological QOL for gay men and bisexuals. However, minority stress is not a significant mediator for lesbians. Therefore, lesbians may experience minority stress and its relationship to psychological QOL differently than gay men and bisexuals due to higher societal acceptance. This study provides support for examining lesbians, gay men and bisexuals separately rather than as one sexual minority group.
