SO_(x) from fuel oil has caused much air ***,the desulfurization of fuel oil is *** desulfurization(ODS),as one of the most efficient nonhydrodesulfurization technologies,has become a major solution of desulfurization for fuel oil owing to its high reactivity for the removal of refractory organic sulfur compounds including dibenzothiophene(DBT)and its derivatives under mild reaction conditions[1].

Currently,it is of great significance to develop new proton-conduction materials with high proton conductivity,high stability,and good conducting durability to meet the demands of fuel cell and ***,we prepared two composites DETA-HPW@MIL-101-SO_(3)H 1 and TETA-HPW@MIL-101-SO3H 2(DETA=diethylenetriamine,HPW=H_(3)PW_(12))_(4)0·xH_(2)O,MIL=Material Institut Lavoisier,TETA=triethylenetetramine)by encapsulating polyoxometalate(POM)and organic amine into a sulfonated MIL-101 through a step-by-step dipping ***,1 and 2 have high proton conductivities of 6.4×10^(−2) and 2.9×10^(−2) S·cm^(−1) at 65℃ and 95%relative humidity(RH),respectively,which can be attributed to the fast proton transfer among acid–base pairs formed between HPW and organic amine as well between sulfonic acid and organic ***,the time-dependent test in proton conductivity displays that their proton-conduction properties have good stability and durability,which benefit from that the electrostatic interactions among acid–base pairs and the limitation of opening size of MIL-101-SO3H make HPW and organic amine stably exist in the cages of MIL-101-SO_(3)*** remarkable proton-conduction properties(high proton conductivity and high stability)of the two composites make them become promising proton-conduction materials.

Canine Infectious Hepatitis (CIH) is an acute viral infection with high mortality rate in puppy. CIH is a member of adenovirus family and transmits by suffering canine. CM virus contains a single strand DNA. By now, there is a kind of inactivated virus vaccine that is costly and lack of long-term immunity protection, and requirement of multiple dose. In recent years, plasmid DNA vaccines have attracted much attention for their ability to induce both humoral and cellar immune responses. There are likely to be inexpensive and easy to produce and provide an alternative to inactivated or virus vector subunit vaccine. Directed injection of the plasmid DNA in vivo results in the synthesis of viral proteins in host cells and may thus mimic the action of attenuated *** the present study, a plasmid vector expressing CIH Loop1 and Loop2 protein was constructed. Canine adenovirus DNA was isolated and purified from the cultured BHK cells. The loop1 and loop2 fragments were amplified by polymerase chain reaction (PCR) method. Then the PCR product was digested with restriction enzyme Smal I for 10h. After digestion, the loopl and loop2 linked with T4 ligase. The gene fragment of DNA (loop1-loop2) was obtained by second PCR. It was cloned into pVAX1 plasmid that the CpG have been inserted. Finally, canine hepatitic DNA vaccine was constructed successfully.
