Identification of kinetic models and estimation of reaction and mass-transfer parameters is an important task for monitoring, control and optimization of industrial processes. A methodology called Extent-based Model Identification has been developed to sep ...
Gas-solid catalytic reaction systems depend on a combination of several dynamic eects, such as mass transfer, chemisorption and surface reactions taking place simultaneously. In this master thesis, the extension of the method of extent-based model identica ...
Calcium silicate hydrate (C-S-H) is the main hydrate phase in Portland cements. Its composition
varies depending on the Ca/Si ratio and on the presence of other ions such as aluminium (called CA-
S-H) or alkalis.
This thesis aimed to study the compositi ...
In this laboratory study a multidiagnostic experimental approach including Fourier transform infrared (FTIR) absorption of 1 to 2 mu m thick polycrystalline ice films, residual gas mass spectrometry (MS) and total pressure measurement were employed. Both a ...
Amorphous nanoparticles (a-NPs) have physicochemical properties distinctly different from those of the corresponding bulk crystals; for example, their solubility is much higher. However, many materials have a high propensity to crystallize and are difficul ...

In this project a new fabrication strategy for suspended microchannel resonators (SMRs) is described. SMRs are biosensing devices with the liquid flowing inside of them, allowing real time measurements of fluidic samples, while devices can be kept in dry e ...
Crystallization of the Earth's inner core fractionates major and minor elements between the solid and liquid metal, leaving physical and geochemical imprints on the Earth's core. For example, the density jump observed at the Inner Core Boundary (ICB) is re ...
Kinetic modeling of batch reactions monitored by in-situ spectroscopy has been shown to be a helpful method for developing a complete understanding of reaction systems. Much work has been done to demonstrate the ability to model dissolution, reaction and c ...
The rigidity temperature of a solidifying alloy is the temperature at which the solid plus liquid phases are sufficiently coalesced to transmit long range tensile strains and stresses. It determines the point at which thermally induced deformations start t ...
Metal-organic frameworks with high stability have been pursued for many years due to the sustainability requirement for practical applications. However, researchers have had great difficulty synthesizing chemically ultra-stable, highly porous metal-organic ...
