Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In...

The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
Despite the considerable advances of deposition technologies, it remains a significant challenge to form conformal deposition on surface of nanoporous carbons. Here, we introduce a new ambient hydrolysis deposition method that employs and controls pre-adsorbed water vapor on nanoporous carbons to define the deposition of TiO₂. We converted the deposited...

Data from the southern Cascade Mountains of
Oregon has been collected for application in computer
analysis of snowfields. Vegetation type, canopy
cover, slope, aspect, insolation, and snowfield
ground truth delineation are given consideration.
In addition, a procedure for transferral of data
onto Landsat imagery was derived.

We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Throughout the course of this thesis, I argue that the prose of David Foster Wallace, specifically his posthumously published novel The Pale King, inhabits a middle ground between universal sincerity and the particularized authenticity of postmodern irony. I examine Lionel Trilling's definitions of sincerity and authenticity before moving toward an...
