This dissertation presents two experimental studies of DNA polymers inside nanofluidic devices with well-defined topographic features. Those features include square pits and rectangular trenches etched …
Diffusion-ordered NMR spectroscopy (DOSY) and related diffusion coefficient-formula weight (D-fw) correlation analysis are described. DOSY experiments use gradient pulses to label spins within the NMR …
When one adopts the perspective of the potential energy landscape ensemble, the evolution of a liquid system transforms into a problem of the free diffusion …
Partial melting of the mantle occurs predominantly in the spinel lherzolite stability field, where pyroxenes are consumed to produce olivine and basaltic melt. The phase …
We present an examination of near-wall colloidal particle dynamics, their associated measurement techniques and applications to micro- and nano-scale fluid flows. The dynamics of small …
We study the rheological properties of reconstituted actin networks by tracking the thermal motion of embedded micron-sized probe beads with four types of surface coatings. …
It is well known that diffusion induced stresses are responsible for capacity fading of electrodes in lithium-ion batteries. Here, we develop an atomistic-based continuum model …
Sn, which offers large theoretical capacity (994 mAh/g), is a potentially useful anode material in lithium-ion batteries. However, Sn exhibits irreversible capacity loss through mechanical …
Novel applications of materials in small dimensions are emerging in areas ranging from electronics, computers, health technologies, laser and fiber optics, to energy harvesting and …
In order to understand the stress behaviors in thin films, three related topics were investigated. First, intrinsic stress generation mechanisms were studied by in-situ stress …
