Preparation of liposomes and Encapsulation of Bioactives Using Supercritical Carbon Dioxide
DownloadSpring 2017
Liposomes are versatile vesicles of a phospholipid bilayer, which offer great protection for active compounds. Encapsulated compounds can be protected from the unfavorable external conditions so that their chemical stability and bioavailability can be greatly enhanced. The supercritical carbon...

Protein Separation with Self-Assembled Nanoparticle Beds: Mechanism and Separation Performance
DownloadSpring 2016
This thesis reports the separation behavior of SDS-protein complexes in colloidal self-assembled (CSA) nanoparticle beds, and the processes of stabilization of CSA beds for high voltage separation. First, the variation of electrophoretic mobility with molecular weight (6.5-66 kDa) of SDS-protein...

The centrifugal particle mass analyzer (CPMA)-electrometer system has been proposed as an alternative method of calibration for devices that measure black carbon. This system is proposed to replace the current calibration standard of NIOSH 5040. The repeatability and intermediate precision of the...

Monodisperse Pd nanocubes of 20 nm rib length and Pd nanospheres of 3 nm diameter deposited on corundum were used as efficient tool to reveal structure sensitivity of three-phase hydrogenations of unsaturated alcohols. For an olefin alcohol hydrogenation in the kinetic regime, surface (100) atoms...

The objective of this research was to explore the feasibility of using SPI nanoparticles to improve the absorption of vitamin B12 (VB12) using in-vitro and ex-vivo models. The molecular interactions between soy proteins and VB12 were firstly studied and the results revealed that VB12 was bound to...

Study of Enhanced Deposition due to Magnetic Field Alignment of Ellipsoid Particles Using Direct Numerical Simulations
DownloadFall 2012
A recent in vitro study demonstrated a non invasive method to enhance local deposition in a small airway by controlling the angular position of magnetic high aspect ratio particles. This technique could mitigate the challenge of providing sufficient therapeutic effects when using aerosolized...
