We consider the K-body local correlations in the (repulsive) 1D Bose gas for general K, both at finite size and in the thermodynamic limit. Concerning the latter we develop a multiple integral formula which applies for arbitrary states of the system with a smooth distribution of Bethe roots, including the ground state and finite-temperature Gibbs states. In the cases K ≤ 4 we perform the explicit factorization of the multiple integral. In the case of K = 3 we obtain the recent result of Kormos et al, whereas our formula for K = 4 is new. Numerical results are presented as well.

2001) Synthesis and characterization of halogen-containing ferroelectric liquid crystals and side chain liquid crystalline polymers, Liquid Crystals, 28:3, 365-374, A new series of ferroelectric liquid crystals and side chain liquid crystalline polymers based on halogen-containing chiral centres has been synthesized. Chemical structures were analysed by NMR. Liquid crystal phases were characterized by diOE erential scanning calorimetry, optical polarizing microscopy, and X-ray diOE ractometry. The behaviour of the liquid crystalline phases was investigated as a function of spacer units and diOE ering terminal asymmetric moieties. It was found that phase transition temperatures decreased with increasing length of the oligooxyethylene spacer unit. DiOE ering terminal asymmetric moieties led to diOE ering mesophase phenomena. Furthermore, a wide temperature range (including room temperature) of a chiral smectic C phase was achieved.

Based on the thermal dissipation issues of electronic devices, a novel thermal radiation material (TRM) using specific ceramic powder and polymer composite technology was developed. This material presented the advantages of high infrared ray emissivity, electrical insulation, and environment reliability. The thermal emission spectra wavelength was covered from middle to far infrared rages. The emissivity was higher than 90% between 4~14µm wavelength. To realize the effect of heat dissipation of thermal radiation material, thin film was obtained by coating this composite on the heat sink of 13 watts LED bulb. After drying process, the dissipation properties were evaluated by thermometer. MCPCB temperature of coating LED bulb would be decreased 13.5 degree Celsius which was lower than un-coating one. And the heat sink temperature of coating LED bulb was decreased about 8 degree Celsius. Furthermore, the lumens were also investigated. Due to the decreasing of LED temperature, the lumen per watts was increased over 14%. These characteristics made them suitable for electronic devices applications in handheld products, LED, heat sink coating, projector, industry computer, and cloud equipment.
