研究领域

My research interests are in the areas of energy-materials, hydrogen storage and metal matrix composites (MMCs). Major contributions to the fields are: Identification of hydrogen trapping ability in different microstructures to provide a better understanding on the hydrogen embrittlement of steel. Application of Ni encapsulation on hydrogen storage alloys in the preparation of Ni-MH battery electrodes using sintering rather than via the paste method, so that the conductivity of the electrodes can be largely enhanced. Synthesis of nanostructured Ni(OH)2 with the performance of nickel electrodes increased by 30% in capacity. Development of aluminium matrix composites with nano-reinforcements. With only 1% of these reinforcements, the tensile properties of the composites are better than or comparable to those of composites with 10% micrometric reinforcements. The composites also have a very high creep resistance up to 0.8 of their melting points.
