2. Pressure-Induced Amorphization and Distinct Amorphous States of Clathrate Hydrates
Abstract : This thesis summarizes a study on the pressure-induced amorphization (PIA) and structures of amorphous states of clathrate hydrates (CHs).PIA involves the transition of a crystalline material into an amorphous solid in response of mechanical compression at temperatures well below the melting point.

4. Theoretical Studies of Natural Gas Hydrates and H-bonded Clusters and Crystals
Abstract : In this thesis H-bonded systems (natural gas hydrates, water clusters, and crystal ice) are studied by density functional theory (DFT) computations.Natural gas hydrates (NGHs) play an important role in energy and environmental fields: NGHs are considered as a promising backup energy resource in the near-future due to their tremendous carbon content; improper exploration of NGHs could induce geological disasters and aggravate the greenhouse effect.

5. Improving Thermoelectric Properties of Inorganic Clathrates by Atomic and Microscale Structure Engineering
Abstract : As more countries are aiming for a carbon-neutral economy, technologies that utilize renewable energies are increasingly being considered. Thermoelectric materials enable the direct conversion between a thermal gradient and an electrical potential gradient, and are thus exploited for applications such as waste heat recovery. READ MORE
