Charge Transfer Reactions in Porous Materials

Porous materials, such as sol-gels and zeolites, contain nanometer-scale spaces in which molecules are confined, leading to significant changes in their chemical dynamics. In this dissertation, the effects of confinement on chemical behavior are studied. By understanding how the properties of a material affect functionality, the rational design of porous materials for applications such as catalysis may be achieved. The study of entropy and free energy of a nanoconfined model dye molecule with Monte Carlo methods is discussed in Chapter 2. In Chapter 3, infrared spectra of a model proton-transfer complex calculated using mixed quantum-classical molecular dynamics are calculated. These studies indicate that charge transfer dynamics and equilibria are spatially-dependent in nanoconfined systems. This is reflected in the time-dependent fluorescence and infrared spectra, discussed in Chapters 2 and 3, respectively. Chapter 4 describes quantum chemical studies of a carbon acid being developed for use in Friedel-Crafts acylation as a solid acid catalyst

A Thematic Analysis of Faculty Advice for Doctoral Students

The present study examines advice given by the graduate faculty in a department (n=24) to new Ph.D. students in the department. The thematic analysis employed inductive coding to draw themes from the data, and seven salient themes emerged from the interviews: relationships, openness, individuality, purpose, academic work, self-care, and logistics. Grounded in a theoretical framework of social constructivism, the present study analyzes how knowledge is created as a social artifact that is passed down from faculty to graduate student and highlights the ways in which doctoral students then shape the meaning of said knowledge through their own interpretations and actions. This study analyzes the interview data to examine the ways in which systemic challenges of pressure and power are perpetuated within academia and highlights the many ways in which graduate faculty are truly invested in their students and their well-being. The findings serve as a catalyst for introspection for the various actors in academic systems, while providing an uplifting motif of genuine care for the overall wellness of doctoral students

Häusliche Trinkwasserinstallation von Fällen mit Legionärskrankheit: Effizient ermitteln – systemisch sanieren

Im Rahmen der von 2016-2020 durchgeführten Berliner LeTriWa-Studie (LeTriWa = Legionellen in der Trinkwasserinstallation) wurden 19 nach Trinkwasserverordnung untersuchungspflichtige Trinkwasserinstallationen untersucht, wo im zugehörigen Haushalt eine Fallperson wohnhaft war. Im Beitrag wird dargestellt, an welchen Stellen in der Trinkwasserinstallation des Gebäudes und des betroffenen Haushalts monoklonale Antikörper (MAb) Typ 3/1-positive (virulenzassoziierte) Stämme mit welcher Wahrscheinlichkeit zu finden waren und ob auch Kaltwasserproben positiv waren. Wir untersuchten, welche Konsequenzen sich aus den Ergebnissen von Standard-Haushaltsproben sowie den Ergebnissen aus einer weitergehenden Untersuchung für die Ermittlung von Fällen von Legionärskrankheit generell ableiten lassen

Remodeling of the Cortical Structural Connectome in Posttraumatic Stress Disorder:Results from the ENIGMA-PGC PTSD Consortium

BACKGROUND: Posttraumatic stress disorder (PTSD) is accompanied by disrupted cortical neuroanatomy. We investigated alteration in covariance of structural networks associated with PTSD in regions that demonstrate the case-control differences in cortical thickness (CT) and surface area (SA). METHODS: Neuroimaging and clinical data were aggregated from 29 research sites in >1,300 PTSD cases and >2,000 trauma-exposed controls (age 6.2-85.2 years) by the ENIGMA-PGC PTSD working group. Cortical regions in the network were rank-ordered by effect size of PTSD-related cortical differences in CT and SA. The top-n (n = 2 to 148) regions with the largest effect size for PTSD > non-PTSD formed hypertrophic networks, the largest effect size for PTSD < non-PTSD formed atrophic networks, and the smallest effect size of between-group differences formed stable networks. The mean structural covariance (SC) of a given n-region network was the average of all positive pairwise correlations and was compared to the mean SC of 5,000 randomly generated n-region networks. RESULTS: Patients with PTSD, relative to non-PTSD controls, exhibited lower mean SC in CT-based and SA-based atrophic networks. Comorbid depression, sex and age modulated covariance differences of PTSD-related structural networks. CONCLUSIONS: Covariance of structural networks based on CT and cortical SA are affected by PTSD and further modulated by comorbid depression, sex, and age. The structural covariance networks that are perturbed in PTSD comport with converging evidence from resting state functional connectivity networks and networks impacted by inflammatory processes, and stress hormones in PTSD
