NONDIMENSIONALIZATION TECHNIQUE  FOR DIFFERENTIAL EQUATION IN PHYSICS

NONDIMENSIONALIZATION TECHNIQUE FOR DIFFERENTIAL EQUATION IN PHYSICS

By Nguyen Phuong Duy Anh
In physics, the majority of natural events have been researched and described using differential equations, each having its own initial and boundary conditions. These differential equations contain a large number of fundamental constants as well as other model parameters. They add to the equation's complexity and rounding errors, ...
THE INFLUENCE OF CARRIERS ON THE PHOTOCATALYTIC ACTIVITY REDUCED NO EMISSION OF THE TNTs/g-C3N4/DIATOMITE COMPOSITE

THE INFLUENCE OF CARRIERS ON THE PHOTOCATALYTIC ACTIVITY REDUCED NO EMISSION OF THE TNTs/g-C3N4/DIATOMITE COMPOSITE

By Le Thi Pho
Diatomite from Tuy An district, Phu Yen province, with different purities and diatom integrity as catalyst carriers, were adopted to prepare TNTs/g-C3N4 composite catalysts by a sol-gel method, with an optimal weight ratio of 1:1 for TNTs/g-C3N4 and diatomite. Compared with pure TNTs, g-C3N4, and TNTs/g-C3N4, the obtained composite photocatalysts ...
APPLYING THE DFT METHOD, CONSIDER THE  PROPERTIES OF Sc DOPED WITH ASiNRs

APPLYING THE DFT METHOD, CONSIDER THE PROPERTIES OF Sc DOPED WITH ASiNRs

By Thanh Tung Nguyen, Huynh Minh Phu
Investigating the characteristics of the three-step sorption of Sc on armchair silicene nanoribbons is the aim of this study. Since absorbed energy is the largest of the bridge, hollow, valley, and top positions, the hollow position is selected first. The structural state of the second step has an energy of ...
EVALUATION OF THE EFFECTIVENESS OF NO REMOVAL  USING THE PHOTOCATALYTIC ACTIVATED MATERIAL S-TiO2/DIATOMITE

EVALUATION OF THE EFFECTIVENESS OF NO REMOVAL USING THE PHOTOCATALYTIC ACTIVATED MATERIAL S-TiO2/DIATOMITE

By Le Thi Pho
S-TiO2 typically exhibits high photocatalytic activity, but its powdered form makes it difficult to apply practically in environmental treatment. Diatomite from different locations varies in purity and integrity of the diatomaceous earth, making it a suitable catalyst support for synthesizing mixed-phase S-TiO2 catalysts using the sol-gel technique. The synthesized photocatalyst ...
