Tubular flame synthesis of alumina particles: Effect of the addition of energetic materials to precursors

 Dr. Tomoyuki Hirano, a specialist in the design of high-performance particulate materials, has made a groundbreaking contribution by synthesizing alumina particles using tubular flame combustion. This innovative approach, introduced for the first time by Dr. Hirano, explores the impact of incorporating energetic materials into precursors on particle characteristics.
 His research is particularly noteworthy for its efficiency, leveraging combustion energy and achieving high-precision control over particle morphology and composition through the manipulation of temperature and gas concentration. Systematic experiments demonstrated that the use of ammonium nitrate (AN) as a precursor additive generates a large volume of gas during decomposition and combustion, leading to deformation in particle formation. In contrast, the addition of urea results in an increased proportion of the high-temperature α-alumina phase.
 These findings are significant as they align with current research initiatives in energetic materials, which are strongly supported by our society. The potential for practical applications of this method is substantial, paving the way for future advancements in the field. Furthermore, Dr. Hirano's ongoing collaborations between industry and academia are anticipated to expand, yielding further innovative outcomes.
 In light of his exceptional contributions and the promising implications of his work, we firmly believe that Dr. Hirano is highly deserving of the Encouragement Award. His pioneering research and dedication to advancing particle design exemplify the qualities we seek to recognize and encourage.
