Deep eutectic solvent study
The freezing point of the mixture of two components at a certain ratio is smaller than each of the individual component, and the mixture mixed at this specific point is called deep eutectic solvent (DES). DES shares a lot of attractive properties of ionic liquids (ILs) like low vapor pressure, high viscosity and thermal conductivity. Compared with ionic liquids, DES has advantages of easy preparation, high purity and more environmental friendly. In this project, we mainly investigate properties of some novel prepared DES, and utilize them for polymeric functional materials.

Polymerized pyrrolidinium-based ionic liquid membranes for carbon dioxide capture
Ionic liquids (ILs) are salts at liquid state, and are considered to be a new generation of green solvent compared with traditional organic solvent. By making ILs to the form of IL membranes, it is an effective approach to high light the properties of ILs and advantages of membrane technologies. In this work, we fabricate the IL membranes, conduct a variety of characterizations of the IL membranes, and utilize the novel prepared IL membranes for gas separation applications.

Preparing RGO/Mn3O4 Nanocomposite by Using Three Different Manganese Precursors via Microwave Heating
Graphene or graphene-based materials, whin the last decade, has attracted tremendous attentions from researchers and scientists in different fields. Recently, manganese-anchored graphene material arises as a practical and promising material for the next generation of supercapacitors. This composite combines the merits of manganese oxide, which are high energy density, low cost, environmentally friendly and natural abundance, and merits of graphene, which are large surface area and high electrical conductivity, to be the candidate of supercapacitors with unique and excellent properties. Herein we employed a fast ane energy saving method to synthesis the graphene nanocomposite and characterized the samples with multiple techniques.

The Design of Ultrafast Routes to Synthesis Carbon Nanotubes by Microwave
Carbon nanotube is a new functional material with unique nano-scale structures and has the potential to get applied in many different areas like microelectronics, drug delivery, painting material, and mechanically enhanced materials. In our research, some ultrafast routes to synthesis carbon nanotubes by microwave irradiation are designed. And carbon nanotubes can be prepared in 15 seconds--10 minutes. Besides, some other byproducts with special spiral structures called carbon nanocoil is also produced. Though the production scale and yield is still small and the control of carbon nanotube growth await studying. It has the potential to develop to a energy-efficient and less time-consuming method to replace those traditional methods being used now.

Developing ionic liquid-based microwave-assisted microextraction for the detection and tracking of hydrophobic pesticide compounds in environmental matrices
Pyrethroids, synthesized derivatives of the natural insecticide pyrethrins, are neurotoxic pesticides used to control agricultural and domestic insects. In this research project, to remove the pyrethroids compounds from the water environment, novel ionic liquids are used as solvent, and dispersive microextraction is conducted with microwave assistance. HPLC is used for the detection and tracking of the pyrethroids compounds. The main point is to test the newly synthesized ionic liquids for dispersive microextraction and the effect of the microwace assistance.

Synthesis of Tetrahydrafuran from N-butane
For the synthesis of tetrahydrofuran, we got varieties of methods from the journals and patents, and in this design we used n-butane to get pure tetrahydrofuran. Aspen Plus was used for the simulation of the process and economic analysis was also performed. Although heat integration and stream change was also considered, after the optimization, the net present value is still negative. However, we made the deficit to be less after our design. Furthermore, discussion and suggestion for this synthesis process was also proposed.

Experimental studies on synergic complexation extraction of hydroxy acid from fermenation liquid
Liquid-liquid extraction is one of the most important trodational chemical separation method. In this research project, trioctylamine and tributyl phosphate were used as complexing agent, and octanol and sulfonated kerosene were used as diluent. The experiment was conducted in Kühni synergic complexation extraction column. In this project, the effect of the temperature on extraction and reextraction was contrasted, and also other factors were also taken into consideration.

Study of establishment in long-term institution of volunteers
This is a research project sponsored by Communist Youth League Committee of ECUST in the background of World Expo Shanghai 2010. Students from a variety of majors with excerlent leadership and great enthusiasm to volunteer fairs are involved in this project. In this research program, the role of the volunteers in society was analysised based on the role theory in sociology. A book was also published based the project: Role Theory Perspective Expo Volunteers (Chinese Edition).

Determination of polyphenol content in a variety of teas
Tea polyphenol is a series of polyhydroxy phenolic compounds in tea trees, and the mass fraction is the highest in tea ( 30%), especially green tea. Three kinds of Chinese tea samples was tested in this experiment with iron tartrate colorimetry (UV-Vis spectrophotometry) followed by data analysis. Although this is an easy basic analytical chemistry experiment, it laid good experimental operation fundation and has great influence in my later study.
