この度、本学大学院工学研究科修士2年生の福田涼太さんが、The 17th International Symposium on Sputtering & Plasma Processes（スパッタリングおよびプラズマ プロセス国際シンポジウム、以下ISSP2024）において、「Effect of O content on self-propagating exothermic reaction in Ti/ SiOx multilayer films deposited by RF/DC sputtering（交流／直流スパッタリングで成膜したチタン／シリコン酸化物多層膜の自己伝播反応に及ぼす酸素含有量の影響）」の研究発表を行い、Student Awardを受賞しました。この賞は、ISSP2024おいて優れた講演を行った学生を顕彰するものです。まずは、140件の学生による発表の中から書類審査で50件が選ばれ、最終的に学会当日の発表について投票が行われ、福田君を含む3人が選ばれました。
本学教員の生津資大教授（工学部／専門分野：ナノメカニクス、ナノテクノロジ、機能性材料）の指導のもと、福田さんは自己伝播発熱材料の研究を行っています。生津研究室ではAl/Ni（アルミニウム／ニッケル多層膜）の組み合わせで発熱金属膜を作り、SiC（炭化シリコン）パワー半導体の瞬間接合技術を開発していますが、福田君はこの瞬間発熱材料の医療分野への応用に興味を持ち、生体適合材料であるTi（チタン）とSi（シリコン）酸化物との組み合わせで発熱反応の現象理解を進めています。この研究の過程において、酸素の含有量が増えることで発熱反応のメカニズムが変わり、発熱性能を酸素量で制御できることを見出しました。
福田さんは、「他大学から本学大学院を受験して入学しました。生津研究室はナノ～マイクロ材料の物性評価や機能開拓に力を入れており、その技術的チャレンジは困難の連続でした。今回の受賞によりこれまでの頑張りが報われた気分です。修士論文に向けて最後まで頑張ります」と喜びを語っていました。生津教授は「毎週の研究室ミーティングで厳しい指摘をされながらも日々地道に頑張ってきた成果が認められ、嬉しく思います」と福田さんの努力を称賛しました。

Ryota Fukuda, KUAS Graduate School of Engineering 2nd year master’s course student, received the ISSP2024 Student Award
Ryota Fukuda, a second-year master’s course student at KUAS Graduate School of Engineering has received the Student Award from the 17th International Symposium on Sputtering & Plasma Processes (ISSP2024) held in Kyoto Research Park for his presentation entitled “Effect of O content on self-propagating exothermic reaction in Ti/ SiOx multilayer films deposited by RF/DC sputtering”. This award recognizes outstanding research work and presentation performed by students at the ISSP2024. Firstly, 50 great papers were selected from in total 140 papers that the first author was student, and then only 3 students were selected as the Student Award with their great presentations. Ryota’s research and presentation were very positively evaluated, leading to this award. He was sole Japanese student in the three winners.
Under Professor Takahiro Namazu’s supervision, Ryota is conducting research into self-propagating exothermic materials. In the Nanomechatronics Laboratory, they are developing exothermic metal films, such as Al/Ni, and developing instantaneous bonding technology for SiC power semiconductors. Ryota is interested in the application of this instantaneous exothermic material to the medical field, and is working to understand the phenomenon of self-propagating exothermic reactions in Ti and SiOx, which are known as biocompatible materials. He discovered that the mechanism of the exothermic reaction changes as the oxygen content changes, and the exothermic performances can be controlled by the amount of oxygen.Ryota said joyfully, “I enrolled in KUAS Graduate School of Engineering from another university. The Nanomechatronics Laboratory focuses on evaluating the physical properties and developing the functions of nano- to micro-materials. The technical challenges involved were a series of difficulties. This award made me feel like my hard work has been rewarded. I will continue to work hard until the end on my master’s thesis”. Professor Namazu praised him, and said, “I am pleased that the results of Ryota’s steady daily efforts, despite receiving my strict supervision at weekly laboratory meetings, have been recognized. He deserves the award”.
