From Particles to Sustainability: 18 Years of Research at TUAT

Prof. Lenggoro’s career has traced a wide arc. It began in Hiroshima (1998-2006) exploring the building blocks of materials like ceramics and phosphors. A new chapter started at TUAT where particle technology became tools for biology, environment, and society. What began as questions of optical material etc. grew into solutions for clean water, healthy plants, and sustainable systems. His research story is not focused on just a single field. Instead, it follows particles wherever they could “serve” people and the planet. レンゴロ教授の歩みは、前職の広島大学でセラミックスや蛍光体といった微粒子材料の基礎研究に取り組んだ時代から始まりました。2007年に東京農工大学へ移ってからは、微粒子の研究を生物や環境、社会の課題解決へと広げてきました。

The TUAT Period (2007-Present) began with a Transition Phase (c. 2007-2012), where he applied his expertise in advanced aerosol and colloidal synthesis to create high-performance functional materials (e.g., dielectric particles). A significant “Bio-Application” Pivot (c. 2013-2018) followed, where these core particle engineering techniques were applied to entirely new domains: immobilizing enzymes, studying particle deposition on plant leaves, and fundamentally (discovering and) characterizing novel materials like candle soot. This led to the current Sustainability-focused Phase (c. 2019-Present), where the lab’s work is now fully geared towards creating system-level solutions for global challenges. Chemical Engineering and Environmental/Plant Sciences now lead his output. His societal goal has shifted from Energy to Health and Clean Water. As a result, his impact has transformed; his work is now cited by researchers using particle technology to solve practical problems in water purification, agriculture, and environmental conservation.

東京農工大学(2007年以降)では、まず「移行期」(2007-2012年)から始まり、高度なエアロゾル・コロイド合成技術を駆使して高性能な機能性材料(誘電体ナノ粒子等)を創製しました。その後、大きな「生物・環境応用への転換期」(約2013-2018年)を迎え、基盤となる微粒子工学技術を酵素の固定化、植物葉上への粒子沈着、そして新規材料としての煤(スス)の発見および特性評価といった全く新しい領域へと展開しました。これが現在の「サステナビリティ(持続可能性)への注力期」(約2019年以降)へと繋がり、研究室の活動は地球規模課題に対するシステムレベルの解決策創出へとシフトしています。現在の論文発表は化学工学や環境・植物科学が主導し、社会貢献の目標も「エネルギー」から「健康・福祉」や「きれいな水」へと変化しました。その結果、研究のインパクトも変容し、現在では微粒子工学等を用いて農業、環境保全といった実用的な課題を解決する研究者たちに最も多く引用されています。
