Study the structural, morphological and physicochemical properties of synthetic materials by modern physical and chemical methods such as XRD, FTIR, SEM, TEM, XPS, EDX, BET, TG-DTA, UV -Vis; evaluation of photochemical catalyst using visible light in the decomposition of dyes RR-195, RY-145 on synthetic materials.

Building basis of science and reality for economic - technical efficiency of PE using solutions in CM in Quang Ninh area, to make contribution to increase efficiency of coal production and coal business.

Objectives of the study: Focusing on studying how to incorporate of Fe and Cu atoms into GO and SBA-15 frameworks by atomic implantation method to create new, advanced and highly efficient nanocomposite catalysts for DDT treatment.

Purposes of the research Building a new method (method directly applicable limit theorem) evaluate soil stabilization in accordance with the actual working of the soil environment, the study contributes to the development of stable subgrade; applying the above method to build a computer program, set the tables and nomogram helps engineers quickly determine the height and slope of embankment limited.
