Synthesis of Functionalized Poly(dimethylsiloxane)s and the Preparation of Magnetite Nanoparticle Complexes and Dispersions
(Virginia Tech, 2003-08-21)
Poly(dimethylsiloxane) (PDMS) fluids containing magnetite nanoparticles stabilized with carboxylic acid-functionalized PDMS were prepared. PDMS-magnetite complexes were characterized using transmission electron microscopy, ...
Solution and solid state NMR studies of fluorine tagging reagents
(Virginia Polytechnic Institute and State University, 1985)
Non-covalent Intermolecular Interactions in Polymer Design: Segmented Copolymers to Non-viral Gene Delivery Vectors
(Virginia Tech, 2013-06-01)
Non-covalent intermolecular interactions play a large role in determining the properties of a given system, from segmented copolymers to interactions of functionalized polymers with non-viral nucleic acids delivery vehicles. ...
Synthesis and Non-Covalent Interactions of Novel Phosphonium-Containing Polymers
(Virginia Tech, 2010-08-18)
Phosphonium ions readily compare to ammonium ions in regards to their aggregate characteristics, thermal stability, and antibacterial activity. Ionic aggregation in phosphonium-based polymers provides thermoreversible ...
The correlation of mechanical properties of ethyl cellulose films with shape of distribution curves
(Virginia Polytechnic Institute, 1949)
Radical additions of hydrocarbons, ethers and acetals to alkenes via allyl transfer reaction: A new chain reaction for C-H bond functionalization
(Virginia Tech, 2013-05-10)
Functionalization of hydrocarbons via a free-radical based allyl transfer reaction using various allyl bromide substrates has been previously studied. The work described in this dissertation focuses on the replacement of ...
Regioselective Synthesis of Cellulose Esters
(Virginia Tech, 2014-07-14)
Cellulose is an extraordinarily abundant polymer that can be harvested and purified from trees and other renewable sources. Cellulose derivatives have been widely used as coatings, optical films, fibers, molded objects, ...
Investigation of the supercritical fluid extraction and detection of metals in contaminated soils
(Virginia Tech, 1996-08-05)
In this work the Supercritical Fluid Extraction (SFE) and detection of sorbed metals in contaminated soils is explored. Iron containing samples were spiked onto sea sand and extracted with Supercritical Fluid CO<sub>2</sub>. ...
Improving Photocatalytic Hydrogen Production of Ru,Rh,Ru Supramolecular Complexes in Aerobic Aqueous Solutions
(Virginia Tech, 2017-06-08)
The production of hydrogen fuel via solar water splitting is an important carbon-neutral strategy for the development of renewable resources and has sparked great interest in the scientific community. Hydrogen production ...
