Dr. De-Hao Tsai is a professor and currently appointed as chairman of the Department of Chemical Engineering, National Tsing Hua University (NTHU). He has received his BS degree in Chemical Engineering from National Cheng Kung University (1998), obtained his MS in Chemical Engineering from NTHU in 2000, and earned his PhD degree in Materials Science and Engineering from University of Maryland (USA) in 2007. Prior to his tenure at the NTHU, Dr. Tsai worked as a research scientist in United states at Cabot Microelectronics Corporation and National Institutes of Standards and Technology (NIST)/University of Maryland from 2008 to 2009 and from 2009 to 2013, respectively. 

Dr. Tsai main research interests include the development of functional nanoparticles for chemical engineering, energy and environmental applications. He has more than 90 publications in SCI journals, 1 book chapter and 8 patents. He has been appointed as Management Editor of Chemical Engineering Journal of Taiwan (2018-2019) and Editor of Advanced Powder Technology (Elsevier, 2018-present). Dr. Tsai is serving in the committee of the Asian Society for Colloid and Surface Science (ASCASS), the Taiwan Institute of Chemical Engineers, and the ROC Interface Science Society (Taiwan). His research projects combine academic study and industrial applications, focusing on a combination of colloid & interface science, aerosol technology and chemical engineering to develop advanced nanomaterial dispersions used for specialized chemicals and energy & environmental applications. Current research areas include aerosol-based controlled synthesis of functional nanoparticles and derivative products and the incorporation of new concepts in nanomaterial characterization for the study of surface chemistry and formulation chemistry of nanomaterials.

In Functional Nanoparticle Laboratory, we aim on:

1. Aerosol-based controlled synthesis of functional nanoparticles and derivative products
2. New concepts in nanomaterial characterization : a combination of colloidal- and aerosol-based approaches

Facilities:

1. Electrospray-differential mobility analyser (ES-DMA)
2. Attenuated total reflectance  Fourier transform infrared spectroscopy (ATR-FTIR) 
3. Temperature-programmed reaction systems (atmospheric, high-pressure) equipped with tandem non-dispersive infrared spectrometers and gas chromatography (TCD, FID)
4. Surface area and porosity analyzer
5. Chemisorption station (TPR, TPO, TPD, metal surface area analysis)
6. X-ray diffractometry
7. Mini spray dryer, atomizer, nebulizer
