Current Research Projects

 

Dr Kexue Li

Research Fellow
 
Kexue is using the NanoSIMS to 3D-locate hydrogen/deuterium in oxidised zirconium alloy samples. He has also been using the NanoSIMS on a wide range of other materials including biological cells, nickel alloys, steels and solar cells.
 
Project: 3D-characterization of deuterium distributions in oxidised Zircaloy-4 using high-resolution SIMS
Hydrogen uptake is considered to be a critical process in the corrosion of Zr Alloy because it involved the crack formation and the hydrogen embrittlement impacts the mechanical resistance of Zr cladding. Deuterium labeled 3D depth profile using NanoSIMS is a powerful tool to understand the distribution and the diffusion pathway of hydrogen in the oxide layer and its precipitation Zr alloy. Combined with high lateral resolution and high mass resolution, 3D depth profile measurement by NanoSIMS can be a competitive method to investigate the 3D distribution of particular molecules and atoms.

Past Research Projects

 

Dr Haibo Jiang

Research Fellow

Haibo is using NanoSIMS and complementary techniques to investigate biological problems, in particular cell biology. These projects are in collaboration with Weatherall Institute of Molecular MedicineNational Physical LaboratorySir William Dunn School of PathologyUniversity of Carlifornia, Los Angeles, and Department of Plant Sciences.

Hugh Taylor

D.Phil Student

Hugh is using NanoSIMS to investigate arsenic uptake into rice and arabidopsis to better understand the uptake mechanisms. These projects are in collaboration with Rothamsted Research and Oxford Brookes University, Faculty of Health and Life Sciences.

Hanis Ayuni Mohd Yusof

D.Phil Student

Hanis is using the NanoSIMS to investigate grain boundary segregation in a statisitcally significant number of grain boundaries in bulk samples. This project will explore the application of this technique to both model alloys (Ni-P) and commercial B-containing steels.

Thomas Aarholt

D.Phil Student

Thomas is using the NanoSIMS in conjunction with high-resolution electron microscopes to investigate the hydrogen absorption mechanisms during corrosion of zirconium alloys used in the cladding of nuclear fuel. Delayed deuterium-spiking of the corrosion environment allows for unique contrast of where the hydrogen goes with time. Analysis of several alloys allows for novel microstructure correlation with hydrogen absorption.
