Dr Nguyen Viet Long (N.V. Long) received BSc. degree from Hanoi University of Education and Training in Physics on Study and diffusion theory of AB alloys.
Then, he received MEg. Degree on Structures and properties of metal oxide semiconductor (MOS) for tunnel diodes and capacitors (1997-1999) with Prof Nguyen Duc Chien in Hanoi University of Science and Technology, Hanoi.
After that, he became a researcher in the field of XRD methods and crystal analysis (1999-2000).
He continued to receive Doctor degree on Photonic and optical materials SiO2, SiO2-Al2O3, the mixture of oxides materials doped rare earth (Nd, Er, Eu, Yb etc) (2001-2007) with Prof N.D. Chien in Hanoi University of Science and Technology, Hanoi.
In fact, Dr N.V. Long started to achieve his scientific works with Prof Masayuki Nogami, an International scientist of sol-gel technology in Nagoya Institute of Technology as postdoc research fellow. He had carried out the studies of catalytic materials by chemical methods, such as Pt, Ru, Rh, Ni, Co, Cu, Ag, Fe and Pd based materials for FC, PEMC and DMFC (2010-2013) with Prof Masayuki Nogami (Japan), research and preparation of thermoelectric nanostructures with Prof Michitaka Ohtaki (Japan), following by synthesis of magnetic catalytic nanomaterials: Pt-, Pd-, and Fe-based metals and oxides with Prof Yong Yang (China). Then, he worked at Kyoto University with Prof Toshiharu Teranishi. At present, he continues to work on the interesting topics of synthesis of soft- and hard-phase rare earth magnet nanomaterials with the original structures, typically such as AB (Alloys), AB2O4 (Spinel oxides), ABO3 (Perovskite), RFe12 alloys (ThMn12) (R=Rare earth: Nd, Sm etc), R2Fe17 (Th2Zn17, Th2Mn17) (R=Rare earth: Nd, Sm etc) etc.
So far, he has become reviewers for more than famous 40 international journals from the invitations of many publishers RSC, ACS, Springer, Elsevier, Hadawi etc for evaluation and analysis of manuscripts submitted.
At present, he is a member of Editorial Board, International Journal of Nanomaterials, Nanotechnology and Nanomedicine, Peertechz, India (Editor-In-Chief: Prof Bharat Bhushan, Ohio State University, USA).
In addition, he is a member of Editorial Board, International Journal of Metallurgical & Materials Engineering, 2013-2015 Graphy Publications, India (Editor-In-Chief: Prof. Aris Christou, Department of Materials Science and Engineering University of Maryland United States (USA)).

1. Introduction
Nanotechnology Research Group (NANOTECH) is a research group supported and funded by Saigon University. The research directions of NANOTECH focus on new research in the various forms of nanoparticles, nanostructures, nanomaterials, new synthesis methods and processes, for example as chemical or physical methods, modified polyol methods, their related practical properties and applications for medicine and biology (nanomedicine), energy, environment, society, and life. The crucial issues of the size, the shape, the composition, the morphology, the structure, the related phenomena and properties of the prepared particles in the nano/microscale ranges are very important to their promising practical properties and applications for contributing to tackle urgent global-scale energy, environment issues. We aim to develop the new research directions of specific functional nanomaterials with the high potential of practical applications at Saigon University, Vietnam.
