Prof. Dr. Wilson Merchan-Merchan
Guest Editor
University of Oklahoma
Interests: Dr. Merchan-Merchan’s research areas are nanotechnology, formation of carbon particulate (soot) in oxygenated flames, flame synthesis of organic/inorganic/hybrid nanostructures (for batteries and fuel cells), and plasma processes. His most current research involves: i) the application of oxy-fuel flames for the synthesis of transition metal oxides (TMOs) and mixed TMO nanostructures; ii) the study of soot formation (thermophoretic and optical diagnostics) in biodiesel flames formed with oxygen-enriched air; biodiesel made of various types of feedstocks and blends (biodiesel/petro-fuel); iii) the application of biodiesel and methane flames for generating hydrophobic C-layers on various surfaces for application in heat exchangers; and iv) the study of biofuel’s corrosive properties.

Special Issue Information

Dear Colleagues,

The Guest Editors are inviting submissions for a Special Issue of Energies on the subject area of "Rapid Flame Synthesis of Nanoscale Multi-Dimensional Transition Metal Oxides: Recent Advancements and Prospective Applications". Owing to their unique properties, transition metal oxide (TMO) nanostructures fall within the spectrum of highly sought-after nanomaterials (NMs). This new type of NM has a rich collection of properties and hence endless potential applications. More recently, it has been shown that nanocrystalline TMOs in multiple dimensions (i.e., 1D, 2D, and 3D) have superior properties to microcrystalline TMOs and their bulk counterparts. Furthermore, it has been shown that mixed transition metal oxide (MTMO) nanostructures can have superior performance. One of the main challenges has been the synthesis of these new NMs. A robust, scalable, and energy-efficient method is needed to meet the demand for this new breed of TMO for future applications.   Methods such as chemical vapor deposition, laser deposition, plasma, and sol-gel have been employed for the synthesis of this unique type of TMO. Many of these methods require pre- and/or post-processing for TMO growth, resulting in a batch-to-batch production system that limits scalability. Conversely, the flame method represents a single-step process where TMOs can be formed rapidly; only minutes are needed to form TMOs. Historically, flames have been successfully applied to synthesize TMOs in the form of metal oxide and ceramic powders largely composed of spherical (0D) chain-like particles and their aggregates.  Recently, it has been shown that nanocrystalline TMOs/MTMOs with 1D, 2D, and 3D configurations can be successfully synthesized using flames. The flame method is rapid (a minutes-long process), continuous, and inexpensive. This Special Issue aims to present an overview of the flame synthesis of this new generation of TMOs, the underlying synthesis mechanisms, and, finally, unique applications.
