and surface engineering. We report a novel and universal mussel-inspired anchoring strategy based on cationic amine-modified catechol ligand coupled with 2-methacryloyloxyethyl phosphorylcholine (MPC) moiety. The ligand shows substrate-independent anchoring capability, and the deposited film possesses

monitoring (QCM-D). Adsorption and desorption of biomolecules on/from polyelectrolyte surfaces play a critical role in numerous biomedical and engineering applications. Though some weak polyelectrolytes have been developed for protein adsorption and desorption by regulating the salinity and pH, limited

reports are available about the regeneration of strong polyelectrolyte surfaces between protein-attractive and protein-repulsive states, which is highly desirable but challenging to realize as it is more difficult to fully release the pre-adsorbed proteins from strong polyelectrolytes due to their

III-nitride semiconductors have a combination of structural characteristics and engineering properties that give them a unique place among semiconductors. The fact that they have the same crystal structure makes it possible to deposit alloys with fine-tuned band gaps from infrared to ultraviolet

the three-dimensional growth occurs afterwards. In-situ ellipsometry was employed to investigate the evolution of optical properties of the films during growth, and the results are in good agreement with structural observations.

The electrochemical reduction of carbon dioxides (CO2RR) is a promising solution for mitigating CO2 emissions while simultaneously generating value-added chemicals. From the perspective of materials engineering, understanding the structure-function relationships is crucial in guiding the rational

design of electrocatalysts and advancing CO2RR technologies. Considering its significance attached, this thesis endeavors to investigate the i) BaBiO3 (BBO) perovskite, ii) Bi- and iii) Co-based electrocatalysts with atomically distributed active sites, with particular focus on how the key structural

features including potential-driven reconstructions, coordination environment, and local geometry affect the catalytic performances of CO2RR. The first part of this thesis delves into the investigation of the voltage-driven structural reconstructions in the perovskite BBO, resulting in the generation of

single-phase solid solutions, the higher the EWF of a material, the higher atomic bond strength with higher mechanical stability. However, engineering materials are generally multi-phase materials. It is unclear whether or not the overall EWF of multiphase materials with specific microstructure features
