1. Physical properties and crystallization of theophylline co-crystals
Abstract : This work focuses on the physical properties and crystallization of theophyline co-crystals. Co-crystals of theophylline with oxalic acid, glutaric acid and maleic acid have been investigated. The DSC curves of these co-crystals show that their first endothermic peaks are all lower than the melting temperature of theophylline. READ MORE

2. Adsorption and Mass Transport in Zeolite Membranes
Abstract : Zeolites are commonly used as adsorbents and catalysts in the industry due to their well-defined pores of molecular dimensions. Zeolites offer porous structure, which consists of interlinked alumina and silica tetrahedra with shared oxygen atoms. READ MORE

3. On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes
Abstract : In order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. READ MORE

5. High-Quality Perovskite Films for Efficient and Stable Light-Emitting Diodes
Abstract : Metal halide perovskites have attracted significant attention for light-emitting applications, because of their excellent properties, such as high photoluminescence quantum yields (PLQYs), good charge mobility, narrow emission bandwidth, readily tunable emission spectra ranging from ultraviolet to near-infrared, and solution processability. Since the first room-temperature perovskite-based light-emitting diodes (PeLEDs) reported in 2014, tremendous efforts have been made to promote the efficiencies of PeLEDs, including theoretical simulation, materials design, and device engineering.
