Processing and characterization of nanocrystalline ceria
… it difficult to sinter. In this dissertation, a semi-batch reactor method was developed for directly synthesizing undoped an doped, nanometer-scale CeO₂ particles at room temperature"--Abstract, page iv.

Kinetic analysis of thiol oxidation to study the effects of fluorinated groups on metal phthalocyanine catalysts
… in a reaction-limited, isothermal, bench-scale, semi-batch reactor, with thiol concentrations measured using GC/FID. Conversions of 2-ME to 2-hydroxyethyl disulfide and 4-FBT to 4-fl uorophenyl disulfide in excess of 90% are achieved. Kinetic analyses suggest that the substrate binding and …

Forsterite Dissolution Kinetics: Applications and Implications for Chemical Weathering
… oxalic acid solutions: based on a series of 124 semi-batch reactor experiments over a pH range of 0 to 7 and total oxalate concentrations between 0 and 0.35 m at 25°C. These experiments show that oxalate-promoted dissolution rates depend upon both oxalate concentration and pH. I propose a …

Experimental and kinetic modelling of multicomponent gas/liquid ozone reactions in aqueous phase. Experimental investigation and Matlab modelling of the ozone mass transfer and multicomponent chemical reactions in a well agitatated semi-batch gas/liquid reactor.
… introduced to water using gas/liquid type reactors (e.g. bubble columns). The ozone reactions are hence of the type gas liquid reactions, which are complex to model since they involve both chemical reactions, which occur in the liquid phase, and mass transfer from the gas to the liquid …

Dynamic Modelling and Optimization of Polymerization Processes in Batch and Semi-batch Reactors. Dynamic Modelling and Optimization of Bulk Polymerization of Styrene, Solution Polymerization of MMA and Emulsion Copolymerization of Styrene and MMA in Batch and Semi-batch Reactors using Control Vector Parameterization Techniques.
… emulsion copolymerization of Styrene and MMA in batch and semi-batch reactors are the focus of this work. In this work, models are presented as sets of differential-algebraic equations describing the process. Different optimization problems such as (a) maximum conversion (Xn), (b) maximum number …
