Congratulations to Dr. Tran Ngoc Giang on the publication in the exceptional journal by the subject category

The Institute for Advanced Study in Technology (IAST) is proud to congratulate Dr. Tran Ngoc Giang on his recent publication in the prestigious international journal Langmuir.

The work, titled "Scalable Fabrication of Rewritable, Switchable, and Stable Superhydrophilic–Superhydrophobic Titanium Micropatterns by Laser Surface Texturing and Fluorine-Free Postprocessing," was carried out by Dr. Giang and his colleagues. The study focuses on developing a fabrication process for bio-inspired, switchable superhydrophilic–superhydrophobic (SHPi–SHPo) hybrid titanium surfaces. These structures hold significant promise for applications in  water harvesting, dropwise condensation, and biomedical liquid arrays.

The research group proposed a fluorine- and mask-free method that combines sequential laser machining, silicone oil heat treatment, and ultraviolet (UV) irradiation treatment. This process successfully creates micron-scale micropatterns with high precision, superior stability, and rewritable capabilities. The study also elucidated the underlying surface chemo-morphological mechanisms that govern the wettability transition and demonstrated the ability to switch the superhydrophilic–superhydrophobic states without cross-contamination to the neighboring areas. Notably, this process is an eco-friendly fabrication strategy that opens new avenues for dynamic fluid management, efficient heat transfer, and reconfigurable biomedical interfaces.

This significant research outcome contributes to affirming the scientific prestige of the Institute for Advanced Study in Technology in particular, and Ton Duc Thang University in general, on the international research map.

The Institute for Advanced Study in Technology extends its heartfelt congratulations to Dr. Tran Ngoc Giang and the research team. We wish him and his team continued success and many more excellent scientific achievements.

Once again, our sincere congratulations!
