Sự ảnh hưởng của quá trình hoạt hóa axit sulphuric lên tinh thể ,diện tích bề mặt ,độ xốp ,độ axit bề mặt và khả năng tẩy trắng của Bentonite.

Bentonite là một chất hấp thụ nhôm phyllosilicate, không tinh khiết bằ[r]

In this study, fillers (gravel and brick) of different surface areas were installed on both banks of two test
channels so as to have the same capacity, and effects of differences in surface area and porosity of the
streamside on aquatic biota and activity of the attached biofilm were investigated at[r]

chúng tôi tiến hành thiết kế khuôn bằng hỗ trợ của máy tính với mục tiêu chính là để tối ưuhóa các thông số thiết kế khuôn. Việc sử dụng các giải pháp tích hợp này có thể rút ngắn chutrình thiết kế khuôn và sản xuất, và dẫn đến việc sản xuất các vật đúc khuôn chất lượng caotrong thời gian ngắn nhất[r]

Hạt nano silica mao được tổng hợp bằng phản ứng tetraethyl orthosilicate với một mẫu làm bằng que micellar. Kết quả là một bộ sưu tập các hình cầu nano hoặc que được làm đầy với một sự sắp xếp đều đặn của lỗ chân lông. Các mẫu sau đó có thể được loại bỏ bằng cách rửa với một dung môi được điều chỉnh[r]

In this lesson, you will learn:
• the fundamental elements of hydrologic modeling and analysis
• how to determine the direction of water flow from cells in a study area
• the importance of eliminating sinks from the drainage area
• the importance of including the entire drainage area in the stud[r]

The reaction of methanol oxidation on MoOJTi02 catalysts shows different behaviour depending on
the surface coverage with molybdena and on the specific surface area of the Ti02 support. The nature
of the Ti02 support (anatase or mtile) seems to play only a minor role. Two different zones can be

Big reserve of Ground water in the World: 0,6 % of total world fresh water compares with surface water only 0,02%
Ground water has a small content of solid and organic matter, microorganism (coliforms and e coli) that more safely than surface water (river, lake, lagoon, rain).
