Thermoelectric generator can obtain electric energy from waste heat, which is one of the best ways to recycle the energy from waste heat. At present, most thermoelectric materials tend to be opaque, so the preparation of transparent thermoelectric materials is one of the research directions of thermoelectric materials. In this work, p-type transparent CuI films were prepared by successive ionic layer adsorption and reaction (SILAR) method. The crystalline structure of the film was determined to be γ-CuI by X-ray diffraction. The surface morphology of the film analyzed by scanning electron microscope was flat. In the wavelength of visible light, the average transmittance of CuI film is 60-70%. The energy band of the prepared CuI film is calculated by the formula to be about 3.04 eV. The results show that the CuI film prepared by the SILAR method has excellent optical transparency.

Three optically active Molybdenum (VI) dioxo complexes with tetrahydro salen and substituted tetrahydro salen derivatives as ligands were synthesized and examined as catalysts for asymmetric epoxidation. Complexes of the type MoO2(L)(Solv) and WO2(L) (L = tridentate, trans-2- aminocyclohexanol derived chiral Schiff base, Solv = alcohol) were prepared and characterized by elemental analysis, NMR and IR spectroscopy. These complexes are applicable as catalysts for olefin epoxidation reactions with tert-butyl hydroperoxide (TBHP) being the oxidizing agent. In case of cis-β -methylstyrene moderate enantiomeric excesses of up to 26% can be reached when the reaction is carried out at 0 ◦C.

Polymer plays a function in dominating fluidity in poly-surfactant binary flooding. After optimization and screening, the polymer ought to encounter the demands of terrific water solubility, high-pitched relative molecular weight, substantial viscosifying capability, beneficial injection, good salt opposition of solution, nice biological stability, no pollution to reservoir and environment, wide source, easy transportation and low expense. In this paper, a series of laboratory examinations on high-efficiency composite that floods system for Chang 6 reservoir in Ansai oilfield will be implemented , concentrating on improving and dispensing the existent polymer formulation, and building low molecular weight polymer with colloidal morphology, in order to make it suitable for aim constitution.
