Dear Editor,Protein histidine methylation has been found to be a widespread post-translational modification(PTM)in mammalian cells and represents more than 1.%of all protein methylation events in the human methylome(Ning et al.,2.1.;Kapell and Jakobsson,2.2.).Recently,we and other groups independently identified METTL9 as the first broad-specificity histidine N1.methyltransferase in mammals(Davydova et al.,2.2.;Lv et al.,2.2.).METTL9 methylates a variety of substrates with a common x-His-x-His motif(His is for histidine;the second x is preferably small amino acids:A/C/G/S)and catalyzes methyl transfer to the last histidine.

By applying pressure on the topological insulator Bi2.e3 single crystal, superconducting phase was found without a crystal structure phase transition. The new superconducting phase is under the pressure range of 3 GPa to 6 GPa. The high pressure Hall effect measurements indicated that the superconductivity caused by bulk hole pockets. The high pressure structure investigations with synchrotron X-ray diffraction indicated that the superconducting phase is of similar structure to that of ambient phase structure with only slight change with lattice parameter and internal atomic position. The topological band structures indicate the superconducting phase under high pressure remained topologically nontrivial. The results suggested that topological superconductivity can be realized in Bi2.e3 due to the proximity effect between superconducting bulk states and Dirac- type surface states. We also discussed the possibility that the bulk state could be a topological superconductor.

以CO为还原剂去除NO的选择性催化还原(CO-SCR)技术受到了广泛关注。本文以天然矿物蛭石为载体,采用共沉淀辅助浸渍法(CP-IM)制备了蛭石负载的铁铈双金属氧化物(FeCe/VMT)用于CO-SCR脱硝反应。表征结果显示,相比传统的浸渍法(IM),共沉淀辅助浸渍制备的FeCe/VMT催化剂具有更大的比表面积(1.6.9m^(2./g)和更多氧空位,可以提供更多的活性位点。共沉淀过程形成更多Fe^(3+),并促进了FeCe间的协同作用,有利于提高CO-SCR的催化活性和稳定性。性能测试表明,在300℃和50000h^(−1.的空速下,NO转化率可达1.0%,48h后NO转化率几乎无衰减。当温度降至2.0℃时,NO的转化率依然可以达到97%。同时,利用原位红外光谱和密度泛函理论计算技术,揭示了相应的催化反应机理,为制备大比表面积的负载型催化剂提供了一种方法。

An expanded granular sludge bed （EGSB） reactor inoculated with anaerobic granular sludge was started up with its COD removal performance, self-balancing of pH, biogas production rate and characteristics of the granular sludge during the start-up period being investigated. The results indicated that the EGSB reactor can be started up successfully in {1. d by increasing the organic loading rate rapidly. The removal efficiency of COD was maintained above 93% with influent COD concentration of {1. 000 mg/L and OLR of 37.94 kgCOD/（m 3 ·d）. The EGSB reactor with good pH self-balancing could be fed with fresh leachate of low pH value （4 5）. The biogas production rate was closely related with OLR and COD reduction. Every gram of COD fed （consumed） to the reactor produced 0.34 L STP （0.36 L STP ） biogas with 0.{1. L STP （0.{1. L STP ） methane. Thus, 65% 70% of the produced biogas was methane. Sixty one percentage of COD fed to the reactor was converted to methane, another 33% was converted to biomass by metabolism, and the other 6% was left in the liquid phase. The specific methanogenic activity （SMA） of the granular sludge had increased by 9{1. after {1. d dynamic incubation. The granular sludge in the reactor had good settlement performance with majority diameter of 1.{1.mm.
