Grinding of cement clinkers : linking multi-scale fracture properties to system chemistry, mineralogy and microstructure
… simultaneous determination of the clinker bulk chemistry, the chemistry of the clinker phases, and their abundance. The microscratch test method was downscaled to measure the fracture properties at each characteristic scale of clinkers. Measurements on single silicate grains provided access to …

Three-Way Chemoselectivity Switching through Coupled Equilibria in Complex System and Post-synthetic Modification of Cyclobenzoins
Everything around us is complex systems, including ant-hills, human economies, climate systems, nervous systems, and human beings. In order to understand complex systems often requires cross-disciplinary techniques that merge the knowledge from different fields such as mathematics, physics, …

Removal of nickel and lead from natural clay soil through the introduction of EDTA and coupling ion exchange processes with electrokinetic methodology
… four-point examination of many of the important system properties related to this hybrid technique, and the effect of the textiles on these properties forms the subject of this thesis. Electrical parameters, system chemistry, enhanced solubilization and transport of EDTA and EK methods only, and …

INVESTIGATION OF TRACER GAS VARIABILITY FROM OBSERVATIONS AND MODELS
… the observations and Goddard Earth Observing System Chemistry-Climate Model (GEOS CCM) show tropical tropopause pressure to be related to the ENSO signal in the total column ozone. The GEOS CCM was also used to investigate a possible mechanism for the 3.5-yr signal observed in the mid-latitude …

Polycrystalline Grain Boundary Solute Segregation at Finite Sizes and Temperatures
Engineering defect chemistry allows novel pathways for controlling bulk material behavior, especially for high-defect-density materials like nanocrystalline alloys. With this concept, solute segregation at grain boundaries can be employed as a defect design tool to stabilize such systems against …

Fine Coal Dewatering
… of the novel dewatering aids in the dewatering systems decreased the final moisture contents of the filter cakes to sufficiently low values. There was approximately 50% reduction in the cake moisture of many coal samples with the usage of the novel dewatering aids. The tests were performed on …

Kinetic and structural evolution of functional peptide assembling networks
… The model is then extended for a polydisperse system, where the peptides undergo oligomerization, to simulate the chemical and physical transitions in the DCNs. The polydisperse model shows that the physical and chemical distribution may reach the steady state independently. The assembly …

Redox and complexation chemistry in chloride ionic liquids and molten salts
… is a trove of novel lanthanide and actinide chemistry that must be well characterized to successfully engineer and deploy these systems. Molten chloride salts also offer a direct route to produce high purity lithium metal which is a critical resource for a variety of green energy …

Investigations of and performance improvements in the mercury thiourea complex ion chromatography method for mercury speciation analysis
… aimed at i) understanding the causes of system performance problems, ii) optimizing its chemistry, and iii) coupling it to ICP-MS detection. The new system chemistry described herein is capable of reliably, accurately, and sensitively quantifying both monomethyl (MeHg) and mercuric (HgII …

Characterization of Triggerable Quinones for the Development of Enzyme-Responsive Liposomes
… when designing an enzyme-responsive liposome system. The inclusion of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) or cholesterol decreased the leakage of contents from the liposome systems. Gathering all this information provided me a strong background on the fundamentals of …
