Implementation Of New System For Oxygen Generation And Carbon Dioxide Removal, Angelo Peter Karavolos Jan 2016

Implementation Of New System For Oxygen Generation And Carbon Dioxide Removal, Angelo Peter Karavolos

Open Access Theses & Dissertations

This research effort develops an integrated system for CO2 removal and O2 production. A unique material, dodeca-tungsto-phosphoric acid (H3PO4W12O3; henceforth referred to as DTPA) is mixed with tetra-ethyl-ortho-silicate Si(OC2H5)4 or TEOS. This mixture exhibits unique properties of heat absorption and high electrical conductivity. In the system described herein, the DTPA resides within a cross linked arrangement of TEOS. The DTPA furnishes a source of O2, while the TEOS furnishes structural support for the large DTPA crystals. In addition, the large amount of H2O within the crystal also adsorbs CO2. It can also be cross-linked with other polymers such ...


Dynamic Self-Assembling Dna Nanosystems: Design And Engineering, Divita Mathur Jan 2016

Dynamic Self-Assembling Dna Nanosystems: Design And Engineering, Divita Mathur

Graduate Theses and Dissertations

Over the last thirty years, DNA has proven to be a great candidate for engineering nanoscale architectures. These DNA nanostructures have been applied in areas such as single-molecular analyses, nanopatterning, diagnostics and therapeutics. One of the most commonly-used techniques to engineer DNA-based two- and three-dimensional functional nanostructures is DNA origami, wherein a long single-stranded DNA (called scaffold) is folded into a predetermined shape with the help of a set of shorter oligonucleotides (called staples). This thesis discusses a brief overview of DNA nanotechnology (design, assembly and applications) and three primary projects undertaken in the area of dynamic self-assembling DNA nanosystems ...
