Surface Phase Diagrams for Wetting on Heterogenous Substrates
We propose a simplified description of fluid adsorption on heterogenenous
micropatterned substrates. Using this approach, we are able to rederive results
obtained earlier using effective interfacial Hamiltonian methods and predict a
number of new examples of surface phase behaviour for both singly and
periodically striped substrates. In particular, we show that, for a singly
striped system, the manner in which the locus of surface unbending phase
transitions approaches the pre-wetting line of the infinite pure system, in the
limit of large stripe widths, is non-trivial and sensitive to several
characteristic lengthscales and competing free-energies. For periodic
substrates, we investigate finite-size deviations from Cassie's law for the
wetting temperature of the heterogeneous system when the domain sizes are
mesoscopic.Comment: 12 pages, 13 figure
Solid-to-solid isostructural transition in the hard sphere/attractive Yukawa system
A thermodynamically consistent density functional-perturbation theory is used
to study the isostructural solid-to-solid transition which takes place in the
hard sphere/attractive Yukawa system when the Yukawa tail is sufficiently
short-ranged. A comparison with results for the square well potential allows us
to study the effect of the attractive potential form on the solid-solid
transition. Reasonable agreement with simulations is found for the main
transition properties as well as for the phase diagram evolution with the the
range of the attractive potential.Comment: 14 pages, latex, 5 figures available upon request:

College Experiences: First-Generation Female Undergraduates at the University of Northern Colorado
The number of women entering college and receiving degrees is continuously increasing while simultaneously first-generation students also are making up a larger portion of college students. Though numbers have increased, both populations are frequently viewed as vulnerable when it comes to succeeding in college. Much research has covered each populace separately. Minimal focus on first-generation female (FGF) students has limited the understanding of what the everyday college environment offers to enhance academic, social, and ethical experiences. Past research has focused on financing and academics; however, this study’s purpose was to explore the collegiate experiences that contribute to FGF student’s success and positive individual development throughout college. Qualitative group discussions involving FGF undergraduate students demonstrated key aspects of their college experiences as well as what supportive and educational resources universities were potentially missing. Findings include issues related to family and peer support, society role-expectations, self-development, decision-making, health-related behaviors, emotional well-being, student engagement, and student support services
