This article presents a new modeless technique to extract current disturbances and shows a modular compensation strategy to mitigate these disturbances. The main advantage of this technique is that it does not require any model or state-space formulation to extract current disturbances like other commonly used state-s…
Back Cover: The image depicts spherical glucosamine-displaying brushes, which were synthesized via controlled radical polymerization (ATRP). These brushes possess a high binding affinity towards the lectin wheat germ agglutinin, which leads to the formation of large glycopolymer-lectin clusters. Additionally, the high…
DNA has been utilized to engineer the novel functionalized and networked nanostructures in this dissertation. Based on the anisotropicity and multivalency of branched DNA building blocks, a multifunctionalized nanocarrier platform, termed "DNAsomes", was constructed. These DNAsomes are liposome-like core-shell structu…
In this study, alumina ceramics containing up to 10 wt% of boehmite were sintered at 1550, 1600 and 1650ºC for 1 hour. Water absorption, weight loss, porosity and density values were measured after sintering. Boehmite content caused flocculation during mixing in water suspension. Formation of boehmite agglomerates was…
In this study, the composition of optical glass for GMP(glass molding process) was designed with 'Design of Experiments' method.All the composition batch was performed by 'Create Factorial Design' method.Particularly, SiO 2 , BaO and Al 2 O 3 were chosen major parameters for investigating the effects of components on…
The kinetics and mechanism of the interaction between thiosemicarbazide with di-μ-hydroxobis(1,10-phenanthroline)dipalladium(II) ion complex has been followed spectrophotometrically in pseudo first order conditions in aqueous solution as a function of [Pd(1,10-phen)(H2O)2]2+, [thiosemicarbazide], pH, and temperature.…
A family of water soluble and positively charged L-arginine based poly (ester amide)s (Arg-PEAs) was synthesized by solution polycondensation. These biodegradable Arg-PEAs consist of 3 nontoxic building blocks: L-arginine, diols and dicarboxylic acids. The Arg-PEAs were prepared by the reaction of tetra-p- toluenesulf…
In this work the martensitic transformation in austenitic grains of the duplex stainless stills, the precipitation of chi and sigma phases into the ferritic grains after thermal aging and the carbo-azoturi growth at grain boundaries were investigated. Different types of duplex stainless steel were investigated with al…
Two new salts, [NO2BrBzPy]2[M(mnt)2] ([NO2BrBzPy]+= 1-(2′-bromo-4′-nitrobenzyl)pyridinium; mnt2−= maleonitriledithiolate; M = Ni(1), Pd(2)) have been prepared and characterized by elemental analyses, IR, UV, ESI-MS spectra, TG, and single-crystal X-ray diffraction. The results reveal that when the metal ion is changed…
We have studied the sliding behavior for a 19 M Al(110)/Al(110) defective crystal at 15 GPa as a function of relative sliding velocity. The general features are qualitatively similar to smaller scale (1.4 M) atom simulations for Al(111)/Al(110) nondefective single crystal sliding. The critical velocity, v{sub c}, is a…
Ion energy distribution function (IEDF) of low-energy ion beams extracted from a hot cathode DC ion source have been measured and analyzed using a retarding potential analyzer. Measurements revealed that the height of the IEDF peaks increased in proportion to the discharge current of the ion source. In terms of downst…
The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC)…

The aim of the first part of this research project was to improve the knowledge about the existence and location of adult stem cells in the adrenal gland. Although some experiments might suggest that undifferentiated cells derived from the external periphery of cortical zone, the origin of the regenerating cells remai…
The objective of this thesis work is to model the high-strain rate and dynamic fragmentation of brittle materials using the Discrete Element Method. Fragmentation is an irreversible, nonlinear and random phenomenon.It can be found in many practical applications in engineering and can take place at various length scale…
Ordered mesoporous silica materials are characterized by uniform and tunable pore size, high surface area and large pore volume. In particular, nano-sized ordered mesoporous silica particles have drawn interest from several fields, including biorelated areas, because silica is benign, possesses chemical stability and…

The aim of this work is to study sol-gel and isotropic-nematic phases transitions in suspensions of dioctahedral smectites depending on the morphology and mineralogical nature of clays. Although all the systems studied exhibit a sol-gel at low volume fraction, the liquid-crystalline isotropic-nematic transition could…
We present the results of a percolation-like model that has been restricted\ncompared to standard percolation models in the sense that we do not allow\nfinite sized clusters to break up once they have formed. We calculate the\ncritical exponents for this model and derive relationships between these\nexponents and thos…
