I am working on synthesizing bi-functional catalysts for Li-air battery. The high cost of cathode materials and low efficiency hinder the development of Li-air battery. Therefore, cheap and highly efficient catalysts for both oxygen reduction (ORR) and evolution reactions (OER) are indispensable. I am trying to utilize solution based methods to synthesize Mn oxides, which are potential catalysts for both ORR and OER. The methods can be scaled up without efforts with low cost as well.

Brennan graduated from Cal State Bakersfield with a B.S. in Chemistry, and has industry experience working for Multi-Chem, a division of Halliburton, as an analytical chemist and field chemical solution expert. His  research focus is on energy storage, and uses chemical techniques for battery and supercapacitor synthesis. His interests include novel nanomaterials for high energy density batteries such as lithium-sulfur batteries, and bio-inspired design of electrode materials for specific capacity optimization. Currently, he is working on two novel lithium-sulfur cathode materials, and hopes to begin work on supercapacitors/high-energy hybrid supercapacitor micro/nanostructures. Brennan's hobbies include playing guitar, ping-pong, outdoor activities and barbeques

Robert Ionescu obtained his Bachelor of Science degree in Chemistry from the University of California, Irvine, in 2012. He is currently working on developing novel processing techniques for the synthesis of large-area transition metal dichalcogenide monolayers and their heterostructures for applications in nanoelectronics and spintronics as a graduate student researcher in the Chemistry Department at the University of California, Riverside (email: rione001@ucr.edu).

I am currently a Ph.D. candidate in the Materials Science & Engineering Program at The University of California- Riverside. My advisor and co-advisor are Dr. Cengiz Ozkan and Dr. Mihri Ozkan, respectively.


My research focus is primarily aimed at the design and characterization of scalable, novel, and environmentally benign hybrid silicon-carbon nano-materials for next generation energy storage systems (supercapacitors and Li-ion batteries).

I am currently working on developing spin valve fabrication and spin transfer torque devices. The phenomena of spin polarized current transferring angular momentum to another magnetic layer can be a basic building block of a spin-based computing system.  Also do research outside the field of spintronics. I am attempting to fabricate micro-

supercapacitors and devices on two-dimensional materials such as transition metal dichalcogenides, and I am studying on-chip energy storage. While working on my MS degree, I studied on-chip scale energy harvesting, and my master’s thesis was about the design and fabrication of a vibration-based MEMS energy harvester for low frequencies. The power of lithography still impresses me. It is amazing that billions of transistors can be placed into a relatively small area. But I’m well aware of CMOS’s limits, which is why I also find spintronics so interesting. Spintronics has the potential to overcome some of the problems in the field by being the foundation of a new way of creating and connecting circuits. In the end, I am a learner and a doer. I can’t imagine a career without research or without applying research. That’s probably why I enjoy exploring novel device concepts and fabrication Technologies--they always combine learning and doing.
