Course description
：

Colloid and
Inter
face Chemistry is a fundamental course for nano
-
science, environmental
science, materials, petrochemical engineering, drilling,
oil recovery and transportation of
oil/gas. The instruction of the course is focused on the basic conceptions, theory, properties
of colloids, surface/interfaces between solid, liquid and gases, and properties of typical
dispersions, such as foam, emulsion

and gel.


Course objective
:


The purpose of the course instruction is the students could learn the basic conception, theory
and knowledge of colloid and surface/interface chemistry, the methods for studying and
analyzing problems met in science, engineeri
ng and life, build the capacity for innovating
and developing new technology and use the theory, knowledge and the methods to solve
these problems after they take the course. The students could build the capacity for reading,
listening, speaking and writin
g for communicating and discussing the relevant issues of
colloid and surface science in English.


R
equirement
:

The requirement for students is as following:

2


1.

Learning and understanding the basic conception and theory of colloid and
surface/interface bet
ween substances and the basic properties of colloidal and surface
system.

2.

Mastering the thinking logic and the basic studying and analyzing method of colloid and
surface science.

3.

Solving the problems met in science, engineering and life by using the theor
y,
knowledge, thinking logic and the methods learn from the course.

4.

Promoting the capacity for reading, listening, speaking and writing in English.

5.
