A new approach based on transesterification reaction to synthesizing 2-alkoxycarbonyl-2 -methyl ethyl tin trichlorides and their complexes with dibenzylsulfoxide (DBSO) and hexamethylphosphoramide (HMPA )was reported. They were characterized by elemental analysis,IR and HNMR spectra. The possible mechanism for transesterifications was suggested.

Gelled fuels are the very promising propellants for new-generation rocket and ramjet *** we report a new type of low-molecular mass organic gellant(Z),and prepared four kinds of stable gelled fuels based on hd-01,hd-03,RP-3 and QC liquid fuels,with the critical gellant concentration less than 1%(mass).The characterizations show that the gellant can form 3D network structure,via hydrogen bonding,π-πstacking and van der Waals forces,to fix fuel molecules during the formation of gelled ***,the gelled fuels show high stability,with the remaining gel mass of 0.25%(mass)Z/hd-01 more than 90%even at high centrifugal speed of 7500 r·min^(-1),but the rheological property test shows that all gelled fuels have obvious shear thinning property,which benefits its storage in gelled state while supply in liquid *** gelation of liquid fuels by gellant Z can increase the volumetric net heat of combustion(for hd-01,it increases from 39.58 MJ·L^(-1) to 40.76 MJ·L^(-1) with 1%(mass)Z),and liquefied gelled fuels show the comparable ignition delay time with the pristine liquid ***,the gelled fuels made by gellant Z have better stability,shear thinning and combustion performances,which have great potential for the practical application.

Fractional motion estimation(FME) improves the video encoding efficiency significantly. However, its high computational complexity limits the real-time processing capability. Therefore, it is a key problem to reduce the implementation complexity of FME, especially in hardware design. This paper presents a novel deeply pipelined interpolation architecture of FME for the real-time realization of H.265/HEVC full Ultra-hd video encoder. First, a pipelined interpolation architecture together with an elegant processing order is proposed to deal with different search positions in parallel without pipeline stall and data conflict. Second, interpolation results sharing strategies are exploited among search positions to reduce the memory cost. Finally, the structure of the interpolation filter is further optimized for an area efficient implementation. As a result, the proposed design costs 41 917 slice LUTs on the Xilinx Kintex-7 FPGA platform with a 308 MHz working frequency. The measured throughput reaches a record of 1.238 Gpixels/s, which is sufficient for the real-time encoding of 8192×4320@ 30 fps video.
