  • The Central Highlands in Vietnam are well known for their large basalt plateau and their natural touristic resources with impressive landforms, such as ancient volcanoes, lakes and waterfalls, which are the result of volcanic activities, and of which the waterfalls are especially spectacular scenically. The Dray Nur and Dray Sap waterfalls located on the Serepok River of Dak Lak and Dak Nong provinces, respectively, are remarkable landscapes with a significant aesthetic value. Not only are these waterfalls well known as tourist attractions, they are also noted for a system of impressive geological objects, including basalt columns beneath torrential waterfalls, contemporaneous columna...

  • 17 samples collected from two drill holes (QO.01 and QO.03) at Quoc Oai (Hanoi) were analysed the main chemical compositions in oxides SiO2, TiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O by XRF method and some trace metal elements such as As, Cu, Pb, Zn, Sb, V, Cr, Ni, Cd by AAS method. According to these results, content of SiO2, Al 2O3, Fe2O3 are the highest, the next is K2O, TiO2and the other oxides are very low. The sediments in the Vinh Phuc formation have rich Fe 2O3by laterization, whereas those in the Hai Hung formation have rich K2O by the potassium-absorption in the organic matters. In thesediments, there are close relationship between the alkaline and alkaline earth elem...

  • Zinc aluminum hydrotalcite containing 2-benzothiazolythio-succinic acid (HT-BTSA) and modified by 2-aminoethyl-3-aminopropyltrimethoxysilane (APS) at different concentrations (3%, 5% and 10%). APS modified HT-BTSA (HT-BTSA-S) was incorporated in epoxy coatings at 3% concentration. The corrosion protective performance of the epoxy coatings containing HT-BTSA-S were evaluated by electrochemical impedance spectroscopy, adhesion measurement. The results showed that the presence of HT-BTSA-S improved protection performance of epoxy coating and the best protection was obtained with HT-BTSA modified with 5 % APS.
