The phylogenetic relationship among Chinese Parapenaeopsis species was studied by comparing 16S rDNA and COI gene sequence. The results showed that Parapenaeopsis hardwickii(Miers, 1878) and P. cultrirostris Alcock, 1906 identified from Chinese samples were the same species. Parapenaeopsis cornuta(Kishinouye, 1900), P. incisa Liu and Wang, 1987, and P. sinica Liu and Wang, 1987 were different species. However, their systematic relationship were closer than those of other species, and they formed an advanced branch in the phylogenetic trees. Additionally, the systematic position of P. hardwickii(Miers, 1878), P. hungerfordi Alcock, 1905, and P. tenella(Bate, 1888) were not stable in the phylogenetic trees. More genetic markers such as 18S rDNA and 28S rDNA were supposed to be used to confirm the phylogenic relationship of Parapenaeopsis species.

A new genus and species of axiid shrimp,Carolinaxius kexuae *** *** described and illustrated based on a single specimen collected from an unnamed seamount in the Caroline Ridge,Northwest *** both chelipeds are mis sing,the specimen can be distinguished from other axiid genera by a combination of characteristics:narrowly triangular ro strum;median carina and lateral gastric carina each with one prominent tooth;submedian gastric carinae converging po steriorly,with teeth;cornea weakly pigmented,eyestalk with acute distome sial tooth on dorsal surface;male pleopod 1 two-articled;pleopod 2 with appendix interna and appendix masculina;pleopods 3-5 with appendix *** molecular phylogeny suggests the new genus is most closely related to another recently described genus living inside hexactinellid sponges on seamounts in the Indian Ocean,Montanaxius Dworschak,***,it differs from Montanaxius in the shape of the rostrum,the arrangement of teeth on the carapace,and the shape of the ***,the significant molecular differences support the two belonging to different genera.

A series of white phosphorescent OLED devices with buffer layer and multiple dopant structure is investigated in order to obtain better electro-optic performances and color stability. The color coordinate and color stability are related to the location of multiple dopants layer, and the optimized location can compensate for the change of the blue emission intensity under a high voltage and stabilize the spectrum. The electro-optic performances and color stability can be further improved by changing the composition and thickness of the buffer layer between the emitting layer and the electron transport *** device B2, the distance from multiple dopant layer to buffer layer is 2 nm and the thickness of buffer layer is 5 nm,the maximum luminance, current density, and power efficiency can reach 9091 cd/m^2, 364.5 mA/cm^2, and 26.74 lm/W,respectively. The variation of international commission on the illumination（CIE） coordinate of device B2 with voltage increasing from 4 V to 7 V is only（0.006, 0.004）.

Characterizing the kerogen-hosted pore structures is essential to understand the adsorption,transport and storage potential in organic-rich shale *** this paper,we first separated the organic matter(kerogen)from the mineral matrix in four different shale samples of the Bakken Formation with different thermal maturities and then analyzed their chemical compositions using the wide-angle X-ray scattering(WAXS)***,we acquired small-angle X-ray scattering(SAXS)to characterize the structure of the organic matter and see how these two will *** WAXS results showed that the isolated kerogens have high purity(free of inorganic minerals)and retain different chemical ***,SAXS analysis revealed that the isolated kerogens have similar radius of gyration(R_(g))which is around 90Åand the molecules are in the compact *** on the pore size distribution analysis from the SAXS data,two main peaks were found in all of these four samples with one peak less than 40Åand the other one larger than 1000Å.Also,the TEM images revealed that Sample 1 is abundant in pores with sizes around 20 nm while Sample 2 does not have pores of that size,which agrees with the results from the pore size distribution that was obtained from the SAXS ***,this study exhibits how different analytical instruments can provide us with useful information from complex structures of geomaterials.
