Dr. Mohajeri's main areas of research interest include: hydrogen storage, hydrogen sensors, and thermal stability of polymers and electrochemistry of PEM fuel Cells.
At present, Dr. Mohajeri's research efforts are largely focused to the study of regenaration of Amineborane complexes for on-board hydrogen storage. Ammoniaborane (NH3 BH3 ), the simplest of AB complexes, contains 19.6-wt% hydrogen - if dehydrogenated completely to boron nitride (BN) and H2. Complete dehydrogenation of ammoniaborane occurs at a temperature of about 1200° C. However, for vehicular use and on-board hydrogen storage, the main obstacle to the use of AB complexes (in any form) is their regeneration, off-board, from the spent materials. The objectives of the research proposed here is to probe the underlying chemistry of regeneration ( i.e. hydrogenation) of several of the spent ( i.e. dehydrogenated) AB complexes including ammonia borane and develop energy efficient processes that utilize hydrogen and/or electricity for their regeneration/recovery and reuse, on site vehicle fueling stations.
In addition, she is involved in research and development of "Smart Paint" for hydrogen leak detection. The aim of this work is to generate functional materials that visually detect hydrogen leaks in ambient air from the minute gas leaks from pipes, flange joints and ports.
Dr. Mohajeri is the author or co-author of more than one dozen scientific publications on topics ranging from synthetic organic chemistry, to thermal stability of polymers, metal and chemical hydrides for hydrogen storage. Following are representative examples:
