Zaved Hossain Khan is a Bangladeshi chemical engineer, researcher, and academic leader who is best known as the inventor of nano‑urea, a sprayable nanofertilizer that offers substantial cost savings and reduced environmental impact in agriculture.
Early life and education
Dr. Khan earned his B.Sc. and M.Sc. in Applied Chemistry from the Islamic University, Bangladesh (1999–2005).[1] He obtained an M.S. in Chemical Engineering from the Asian Institute of Technology (AIT), Thailand, in 2007.[1] He was awarded the Doctor of Engineering (D.Eng.) degree from Waseda University, Tokyo, Japan, in 2011.[1]
Academic and research career
Dr. Khan is a Professor and Chairman of the Department of Chemical Engineering at Jashore University of Science and Technology (JUST), Bangladesh.[1] In 2013, he established the first nanotechnology research laboratory in Bangladesh, the "Nano‑bio and Advanced Materials Engineering (NAME)" lab at JUST.[1] He has held several postdoctoral positions, including at Henan University (China), Tohoku University (Japan), and also worked at Waseda University and KIST, Seoul.[1] His research spans nanotechnology, electrochemistry, biosensors, nano‑biomaterials, and agricultural nanotechnology, with more than 170 publications and over 5,800 citations.[1]
Nano‑urea Invention
Among his innovations, Dr. Khan is credited with the development of nano‑urea, a foliar-applied nanofertilizer that delivers nitrogen directly through leaf stomata using nanoparticles sized ~20–50 nm.[1] The nano‑urea formulation significantly reduces conventional urea use, replacing a 45 kg bag (~Tk 4,200 per bigha) with just 500 ml of liquid at a cost of ~Tk 230 per bigha.[1] Field trials demonstrated yield increases of 8–14 %, improved nutrient efficiency, and a potential reduction in Bangladesh's urea imports and carbon footprint.[2] Officially introduced by JUST in May 2025, it is projected to save approximately Tk 220 billion in Bangladesh's agriculture sector.[2]
Patents and awards
Dr. Khan has filed 12 patents with the Bangladesh Patent Office, including innovations related to nanofertilizers.[1]
Dr. Khan also got Bangladesh Academy of Sciences Gold Medal (Physical Sciences) in 2021, University Grants Commission (UGC) Gold Medals in 2018 and 2019, Recognition among the Top 2 % of Scientists Worldwide by Stanford University and Elsevier (2020–2024).
Impact and ongoing work
The innovation has attracted international attention, with interest and collaborative efforts underway from US-based and Vietnamese partners. Expansion efforts include plans for nano‑urea production facilities in Bangladesh and strategic engagement with government and industry to scale up deployment.[2]
