1. Gene transfer by interspecific hybridization in bryophytes
Abstract : The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. READ MORE

2. Lower hybrid current drive in the Tore Supra tokamak
Abstract : To control and extract energy from nuclear fusion reactions, a mixture of deuterium and tritium gases must be heated to temperatures on the order of 100 million degrees, whilst maintaining a sufficiently high density. The main difficulty is to confine the ionised gases, i.e. plasma, until the rate of fusion reactions becomes large enough. READ MORE

3. Hybrid Plasmonic Devices for Optical Communication and Sensing
Abstract : Hybrid plasmonic (HP) waveguides, a multi-layer waveguide structure supporting a hybrid mode of surface plasmonics and Si photonics, is a compromise way to integrate plasmonic materials into Si or SOI platforms, which can guide optical waves of sub-wavelength size, and with relative low propagation loss. In this thesis, several HP waveguides and devices are developed for the purposes of optical communications and sensing. READ MORE

4. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation
Abstract : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. READ MORE

5. Investigation of New Concepts and Solutions for Silicon Nanophotonics
Abstract : Nowadays, silicon photonics is a widely studied research topic. Its high-index-contrast and compatibility with the complementary metal-oxide-semiconductor technology make it a promising platform for low cost high density integration. READ MORE
