Shape memory polymers can response to the external stimulation such as heat, chemicals, mechanism, light, magnetism, electricity and so on, to change their technical parameters. As a type of important functional materials,shape memory polymers have undergone a rapid development since 1980s, which are widely applied in the fields of aerospace, medicine, power electronies, packaging and intelligent control system. In the paper, the shape memory mechanism of shape memory polymers is analyzed. Some common shape memory polymers and their applications in all fields are described in details, respectively. At last, some disadvantages in the development of shape memory polymers are put forward and some suggestions are given.

Based on the knowledge of chemical properties of alcohol and hydrolysis reaction of ester, this article introduces the basic principle and three mechanisms of the green method to prepare propanediol by catalytic hydrogenolysis of glycerol for extending the high school chemistry.

Combining the problems existing in inorganic chemistry textbooks, this paper discussed the principles of textbook construction, emphasized paying more attention to basic knowledge, research frontier, scientific method and inquiry teaching.

In the refresher courses of chemical engineering foundation, the teacher summarizes the common rules and methods, including idealized method, mass balance, energy balance, dimensional analysis, classification, graphic method, boundary layer theory, operating limits and logarithmic mean. The refresher courses consolidate the students' knowledge, and receive good teaching effects.

A novel "heuristic-based teaching" plus "enquiry-based learning" education mode is constructed based on the education experience of the physical chemist Gibbs in chemical historical materials. The "heuristic-based teaching" plus "enquiry-based learning" mode is an important reference for teaching physical chemistry. Digging education method from chemical history is a practical reference for exploring the chemical education method.

Teachers in local universities have been exploring the methods of developing students' learning interest and building students' professional emotion for chemistry. After years of teaching practice of specialty guidance course, the method of cultivating students' chemistry specialty emotion starting from three idoms was obtained and the effect was obvious.

A comprehensive experiment, microwave hydrothermal synthesis and characterization of monodispersed barium titanate nanocrystals, is reported. The monodispersed cubic-like barium titanate nanocrystals(10～20 nm) were prepared using inexpensive reagents by microwave hydrothermal method. X-ray powder diffraction, infrared spectroscopy, Raman spectroscopy, contact angle measurement, thermogravimetric analysis and transmission electron microscope were used to investigate the crystal structure, surface property and morphology of the barium titante nanocrystals. This comprehensive experiment is not only a hot topic in the field of nano-scale material preparation, but also meets the experiment-teaching requirement. Furthermore, its excellent expansibility is beneficial for cultivating students' innovative ability.

A new type apparatus for determination of polymer swelling is introduced. The operation mode of the apparatus is similar to rotating an hourglass. The apparatus can be used to determine swelling curve of a crosslinked polymer in different atmosphere, and determine the maximum swelling degree and thus determine the crosslink density.

To improve the quality of undergraduate education and combine theory and practice, Nankai University organized innovative research activities of "one hundred projects" for undergraduate. College of chemistry guided students to join scientific research innovation training and obtained satisfactory teaching effect. In this paper, the optimized procedure for the synthesis of menthofuran using citronellal as starting material in laboratory is reported as an example for describing "one hundred projects" in detail.

The professional training of instrumental analysis is introduced into teaching system of applied chemistry. Students are expected to complete a series of tasks which involve knowledge and practical skills required step by step, in order to improve their applicable and innovative ability. In the way, good teaching effect is acquired.

This paper introduced the application of CDIO in training of university students' innovative ability with the design of coating machine for flexible solar cells. Students participated in the process of thinking and solving problem in the training, which improved their learning motivation and cultivated their opening thinking, innovative ability, conversation capability, cooperative spirit and responsibility. And these will meet the social requirement of high quality personnel.

The traditional teaching method of physical chemistry is not effective due to the complexity and abstraction of teaching content, which inspires us to apply Sandwich teaching method to physical chemistry of pharmacy. The teaching design and process of surface tension were described in detail in this paper. This teaching method was performed with the aim to motivate students and improve their abilities of expression and communication as well as abilities to analyze and solve problems.

According to the teaching characteristics of biochemistry experiment, this paper discussed the application of ChemLab, ChembioOffice, Design-Expert, Origin and other internet chemical software in biochemistry experiment teaching. The results suggested that combining the chemical software and multimedia technology into the preview, operating instruction, experimental design and data analysis of biochemistry experiment teaching can enhance the visualization and vividness of teaching, excite the interest and initiative in learning, and improve the teaching efficiency.

Reviewing the birth of Nobel Prize, over 34 prizes have been given to spectrum analysis and its related fields. This paper introduces the evolution of several common spectrum analysis methods and the association with centenary Nobel Prize.It discusses the significance of spectrum analysis methods in the modernization of chemical scientific research process.
