The scientific expertise of the MAO Research Group is on the development of functional inorganic nanomaterials, investigation of their novel properties and exploration of their applications for environmental sustainability, energy, catalysis, and optoelectronic devices. Our current research focuses on the design and investigation of advanced materials, mainly transition metal oxides, with novel compositions, structures, architectures and functions, in some cases heterogeneous materials with multi-nanocomponents. The goal is to design advanced materials, achieve desirable properties and functionalities, and tackle complex interdisciplinary material challenges. We employ various synthetic routes to develop desirable targeted materials, and focus on different synthetic conditions, composition and microstructural controlling to fine-tune sensing, catalytic, electrochemical, magnetic, and gas storage properties.
The ability to synthesize and manipulate matter at the nanometer length scale is a powerful driving force in the global scientific and technological community. After a period of rapid development, a wide variety of nanomaterials have been made and a lot without knowing how. Our research emphasizes on the continuous development of novel and scalable synthetic strategies and the study of growth mechanisms for functional nanomaterials. In general, chimie douce synthetic routes are designed and employed for synthesizing functional nanomaterials. We are also interested in investigating and optimizing growth processes by ex situ and in situ characterization methods, e.g. diffraction, spectroscopic and microscopic techniques.
Multifunctional nanomaterials are becoming increasingly important because of their optical, magnetic, electric, catalytic and mechanical properties that do not exist in single-phase materials. Trends toward device miniaturization have led to increased interest in combining various properties into multifunctional materials, so that a single device component can perform more than one task. Our targeted materials include single-phased multi-metallic oxides and nanocomposites. We fine-tune their electronic, magnetic, optical, and mechanical properties by focusing on different synthetic conditions, cation doping, composite structural systems, and microstructural controlling.
Devices and Applications
Application potentials of prepared (nano) materials are explored for national security, sanitation and alternative energy. Examples include the synthesis of luminescent core-shell nanostructures as radiation indicators, the design of hierarchical nanocomposites and three-dimensional electrodes for electrochemical energy storage devices, and the development of novel photocatalytic materials for water treatment and self-decontaminating coatings.

Students, including graduate, undergraduate and high school students, are enthusiastic and responsible team players on our research projects, and are respectful of each other. Underrepresented minorities in our student body (more than 85 percent of Hispanic student population) are a feature of our research programs. I am firmly integrating research programs for underrepresented minorities and REU programs into the operation and keeping this fine tradition.
Get Involved in Research
Involvement in research can be one of the most transformative and rewarding experiences of your college education. The undergraduate research program in Chemistry at UTPA is very active with plenty of opportunities. You may want to be proactive since most openings are not often advertised. If you are interested in inorganic chemistry, materials chemistry or nanoscience, please look at my group web page, read recent publications, talk to students already involved, and then schedule a time to meet with me. Research can be done for credit during the school year and for salary during the academic year.
If you are considering the M.S. or MSIS program in Chemistry at UTPA or you are already in, and interested in inorganic materials chemistry and nanoscience, please schedule a time to meet with me. Additionally, the Graduate Advisor in Chemistry can assist you in obtaining information on degree options, financial aid, admissions requirements, application procedures, and research programs.
We are occasionally looking for a dedicated postdoctoral scholar with expertise on chemical synthesis and characterization of inorganic nanomaterials. If you are interested, please send me your resume.
