Computational studies of three chemical systems
(University of Missouri--Columbia, 2011)
is the study of pyrogallol[4]arene with R-groups R=H and R=phenyl. This macrocycle self-assembles into dimeric and hexameric nanocapsules. Several different structures for the macrocycle and its subunits, their relative energies, and their solvent interactions...
Fully automated deep supervised and unsupervised learning approaches for 3D protein cryo-EM density map reconstruction
(University of Missouri--Columbia, 2019)
of single particle images are required to be extracted from two-dimensional (2D) cryo-electron microscopy (cryo-EM) to build a reliable high-resolution (3D) model. In order to reduce the radiation damage to the biomolecules of interest during the imaging...
Design and analysis of a frequency reconfigurable antenna for wireless communication at 5 GHz
(University of Missouri--Columbia, 2016)
substrate dimensions (L, W, H) are 30 x 27 mm and 1.67 mm respectively, while the patch was made from copper. The substrate was made from the industry standard FR- 4 material, with a relative permittivity of 4.3. The operational frequency bands...
Design and construction of multicomponent spheroidal assemblies on the nano-scale via the self-assembly approach
(University of Missouri--Columbia, 2006)
spherical multicomponent assemblies via the selfassembly approach. Chapter 2 will describe the formation of very large molecular capsules based upon the self-assembly of six macrocycles called the C-alkylpyrogallol[4]arenes. These molecular capsules are held...
Synthethic pathways to multiple surface functionalization of polyhedral boranes
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The chemistry of dodecahydro--closo--dodecaborate(2-), closo-[B12H12]2-, and decahydro-closo-decaborate(2-), [B10H10]2-, with different organic substituents was investigated...
The effects of structural modifications on sigma receptor binding
(University of Missouri--Columbia, 2007)
by replacing the left phenylpropyl group of SA4503 with an N-iodoallyl group yielded a sigma1 selective ligand (1h-7, E-IA-DM-PE-PIPZ) that had appropriate lipophilicity for penetrating the blood brain barrier in the CNS. The in vivo studies using...
Purification and characterization of A[beta] and probing the interactions between myricetin and A[beta] using various spectroscopic methods
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Worldwide, millions of people suffer from symptoms of memory loss and confusion associated with Alzheimer's disease (AD). Mounting evidence suggests ...
Electronic structure of transition metal dichalcogenides under strain
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] The broken inversion symmetry in transition metal dichalcogenides(TMD) generates special orbital characters at the valley points in the Brillouin zone, which leads to various interesting phenomena ...
Establishing a foundation for large DNA transfer to artificial minichromosomes and B insert platforms in maize
(University of Missouri--Columbia, 2019)
. Additionally, BiBAC targeting to a location outside the native chromosomal sets, such as an artificial minichromosome or B chromosome platform, would enable researchers to stack traits without disrupting endogenous sequences....
Felix convivum : platters and transformations of dining behavior in the Roman world
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Most people in the Roman world used ceramic tableware, despite its absence in iconographical and in literary sources. This observation leads to many ...
Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
for an eccentric-circular cam design and a one-cam one-pulley design. By iteratively determining the bow limb, cam, and cable positions a relationship between the drawn length and drawn force will produce a draw-force curve. In fact, this curve represents...
An evaluation of waste plastic in asphalt pavement towards a circular economy
