Premilinary Study in the Cause of Color in Zircon from Krông Năng Mining Area in Đắk Lắk ProvinceVNU Journal of Science: Earth and Environmental Sciences - - 2015
Bùi Thị Sinh Vương, Lê Thị Thu Hương
Zircon occurs in many colors including various shades of pink, red, purple,
yellow, orange, brown as well as less common shades of green, and blue.
Generally, the colors of zircon are caused by the trace element composition
(transition metals, lanthanides, actinides and REEs) and radiation damage
(radiation induced color centers) [1]. The color centers of zircon are complex
and the details surroun... hiện toàn bộ
Evaluation of the Ability to Treat Saline and Acid Sulfate Soils of Biochar from Rice Husks in Greenhouse ConditionsVNU Journal of Science: Earth and Environmental Sciences - Tập 38 Số 3 - Trang - 2022
Tran Thi Thu Huong, Nguyen Xuan Tong, Nguyen Phuc Thuy Duong, Nguyen Van Nghia, Vu Hai, Nguyen Thanh Binh
The purposes of this study were to i) Examine the dynamics of physicochemical
parameters of saline acid sulfate soil as influenced by biochar made from rice
husk; and ii) Evaluate the influence of biochar on the soil quality index. A
greenhouse experiment was carried out by mixing biochar with the tested soil at
ratios of 0; 0.7; 1.5; 3, and 6% (w/w) and incubating for 100 days. Experimental
