Unraveling the Reaction Mechanism of Industrial Processes in Zeolite Catalysis: a Quantum Chemical Approach
… form a crucial catalyst for many petrochemical processes, much of their fundamental reactive behavior is only superficially understood. Most often, catalysts are proposed on an 'ad hoc' basis, without a detailed understanding of their functioning on an atomic scale. It can indeed be difficult to …

Modelling, design and analysis of innovative thermal energy storage systems using PCM for industrial processes, heat and power generation
The topic of this PhD thesis is framed on the study and the analysis of thermal energy storage (TES) systems based on phase change materials (PCM) to be used as a back-up for intermediate temperature applications (up to 250 °C). The work is divided in two part: the first part presents the …

Beyond net-zero carbon emissions in industrial processes through catalyst-aided amine solvents for the indirect co-combustion of natural gas and biomass
This thesis investigates the application of absorber catalysts developed and optimized for effective CO₂ capture in a power production process involving the indirect co-combustion of biomass and natural gas, addressing a crucial case study challenge of carbon emissions from large. By employing a …

Variety and industrial production : the case of housing
Industrial processes have addressed with various degrees of success the question of housing production. If assembly-line methods have proven their efficiency in the production and distribution of low-cost housing, they have been less successful in achieving product diversification, and now suffer …

Raynaud's phenomenon of occupational origin
Many industrial processes are using hand -held vibratory tools and grinding operations in which there is increasing vibration energy entering the hands and arms of operators. The vibration stimulus causes digital artery changes giving rise to Raynaud's Phenomenon of Occupational Origin.

The functional significance of Hsp12p and trehalose in desiccation and oxidative stress in the budding yeast Saccharomyces cerevisiae
… the desiccated state is fundamental as several industrial processes utilise this technology. The significance of the stress response protein and putative hydrophilin, Hsp 12p, was therefore examined in vivo under desiccation conditions.
