Living Polymerization for the Introduction of Tailored Hydrogen Bonding
(Virginia Tech, 2005-06-08)
In an effort to synthesize macromolecules comprising both covalent and non-covalent bonding to tune ultimate physical properties, a variety of methodologies and functionalization strategies were employed. First, protected ...
Targeting RNA Structures with Multivalent Branched Peptide Libraries
(Virginia Tech, 2012-03-19)
RNA is essential for the transfer of genetic information, as the central dogma of biology dictates. The role of RNA, however, is not limited to serving as an information shuttle between DNA and fully functional protein. ...
Synthesis and Study of Polyazine Bridged Mixed Metal Dyads: Electrochemical, Photophysical, and Photochemical Properties of a New Supramolecular Architecture
(Virginia Tech, 2008-10-28)
A series mixed metal supramolecular complexes were synthesized and studied by electrochemistry, photophysics and photochemistry. The complexes consisted of a single RuII or OsII polyazine light absorber bound to a ...
A correlation of the mechanical properties of cellulose nitrate films as a function of the shape of the chain length distribution curve
(Virginia Polytechnic Institute, 1952)
A study of the crease-resistance of viscose rayon
(Virginia Tech, 1942-05-01)
Crease-resistance is a very greatly desirable property in textile fibers. Of the natural fibers, wool exhibits this property to the greatest degree, followed by silk, cotton, and flax, which has a very low crease-resistance. ...
Chelate Assisted, Pressurized, Liquid Extraction for the Removal of Adsorbed Metal Contaminants From Soils
(Virginia Tech, 2000-03-03)
Chelate Assisted, Pressurized, Liquid Extraction (CAPLE) has been developed in our laboratory as an efficient, separation-based, extraction methodology for heavy metals in soils. Unlike current extraction methods used in ...
Adsorbtion of binary vapor mixtures into solids
(Virginia Polytechnic Institute and State University, 1975)
Flow 1H Dynamic Nuclear Polarization Studies in Normal Liquids and Supercritical Fluid Carbon Dioxide
(Virginia Tech, 2002-12-13)
Flow 1H dynamic nuclear polarization (DNP) experiments of small probe molecules (i.e. chloroform and benzene) were conducted in normal liquids (i.e. neat benzene, deuterated benzene, chloroform) and supercritical fluid ...
Transport and Anisotropy inside Ionic Polymer Membranes
(Virginia Tech, 2012-09-18)
Water and ion transport critically determine the performance of many functional materials and devices, from fuel cells to lithium ion batteries to soft mechanical actuators. This dissertation aims to address some fundamental ...
