Abrahams, Isaac - Queen Mary University of London - School of Physical and Chemical Sciences

研究领域

Dr Abrahams’ main area of research can broadly be defined as solid state and structural chemistry with over 200 papers published in this area. Much of his work has been in the field of energy materials focussing on ionically conducting solids for application as electrolytes in batteries, fuel cells and gas sensors. More recently his work has extended to dielectric materials including ferroelectrics and antiferroelectrics with the development of new materials for energy storage. In addition to the synthesis of new materials, he has developed expertise in defect structure determination using neutron and X-ray powder diffraction techniques and in conjunction with a.c. impedance spectroscopy studies has used this to examine structure-conductivity relationships and conductivity mechanisms in a variety of materials, most notably those based on bismuth oxide. In addition to work on crystalline solids, the Abrahams group is very much involved in the study of amorphous solids for applications such as biomedical materials. This work utilises a variety of structural probes such as solid state NMR and EXAFS. As part of its research, the Abrahams group makes extensive use of EPSRC central facilities such as Diamond and ISIS at the Rutherford-Appleton Laboratories and the ILL at Grenoble.
