Successfully fabricated GO-containing nanofluids by using plasma-in-solution interaction delamination technique. GO has an average length and thickness of GO of 1.5 µm and 3.3 nm. The fabricated nanofluids exhibit good stability and a 31% increase in thermal conductivity compared to the base fluid used as the heat sink fuel. The obtained results are hoped to suggest a simple, low-cost and environmentally friendly method to prepare high-performance and low-cost nanofluids for potential applications.
Successfully fabricated nanocarbon quantum dots by solution-interactive plasma method, which is an environmentally friendly method with low manufacturing cost and simple fabrication. The fabricated carbon quantum dots have rich functional groups, the size is less than 10 nm, the fluorescence emission spectral region is wide from 350 - 650 nm with the peak of the spectrum changing with the excitation wavelength.
Plasmonic photocatalytic nanocomposites of TiO2 and Au nanoparticles (NPs) have recently attracted the attention of researchers, who aim to improve the photocatalytic activity of potential TiO2 NPs. In this study, we report photocatalytic activity enhancement for a Au/TiO2 nanocomposite prepared by the plasma–liquid interaction method using an atmospheric microplasma apparatus. The enhanced photocatalytic activity of the prepared Au/TiO2 is demonstrated by the degradation of methylene blue (MB) in water under both ultraviolet (UV) and visible light irradiation. The prior treatment of TiO2 with microplasma in a NH3 and H2O2 solution is found to strongly improve the photocatalytic activity of both the treated TiO2 NPs, as well as the synthesized Au/TiO2 nanocomposite.
Bifluorophores (5-FAM)2 and (6-FAM)2 have been synthesized on the framework of 3,5-diaminobenzoic acid. Two fluorophore molecules were inserted into one site. The luminescence quantum yield of (6-FAM)2 in a buffer solution with pH = 8.5 is 2.4 times lower than for (5-FAM)2. It is shown that both with an increase in the viscosity of the solution in the case of using a water-glycerol mixture and with a change in the microviscosity with the use of a micellar solution, the structural relaxation of molecules in the excited state slows down, which leads to an increase in the fluorescence intensity, the lifetime of excited states, and the degree of polarization.
During the two years of the project, we have had specific scientific exchanges between the two sides. The results of this research have contributed greatly to the training of young scientists in the field of quantum photonics and nano-photonics in Vietnam. It also promoted international publications, which is now a matter for the Vietnam Academy of Science and Technology.
