Development of anode materials is critical to the success of sodium ion batteries (SIBs). Because of the size difference between Li and Na, the commercial anode material graphite in Li-ion...

Ichthyenterobacterium magnum gen. nov., sp. nov., a member of the family Flavobacteriaceae isolated from olive flounder (Paralichthys olivaceus) A novel marine bacterium isolated from the intestine of cultured flounder (Paralichthys olivaceus) was studied by using a polyphasic taxonomic approach. The isolate was Gram-stain-negative, pleomorphic, aerobic, yellow and oxidase-and catalase-negative. Phylogenetic analysis of 16S rRNA gene sequences indicated that isolate Th6T formed a distinct branch within the family Flavobacteriaceae and showed 96.6 % similarity to its closest relative, Bizionia hallyeonensis Ty7T . The DNA G+C content was 29 mol%. The major respiratory quinone was MK-6. The predominant fatty acids were iso-C 15 : 1 G, iso-C 15 : 0 , iso-C 15 : 0 3-OH, iso-C 17 : 0 3-OH and summed feature 3 (C 15 : 1 v6c and/or C 16 : 1 v7c). On the basis of the phenotypic, chemotaxonomic and phylogenetic characteristics, the novel bacterium has been assigned to a novel species of a new genus for which the name Ichthyenterobacterium magnum gen. nov., sp. nov. is proposed. The type strain is Th6 T (5JCM 18636 T 5KCTC 32140 T ).

Over the past few decades, anammox bacteria have been recognized as key players that contribute significantly to the release of large amounts of nitrogen in the global marine nitrogen cycle. In the present study, the diversity, community composition, and abundance of anammox bacteria from the sediments of four diverse regions in the north marginal seas in China were determined via clone library construction and a quantitative PCR analysis. The clone libraries retrieved by the 16S rRNA gene and Hzo gene markers indicated that “Candidatus Scalindua” was the predominant group throughout the sites examined. The 16S rRNA gene clone libraries revealed exceptional diversity by identifying two potential novel anammox clades, as evidenced by the high sequence similarities between these two clades and known anammox genera, and their unique phylogenetic positions with high bootstrap values. However, their potential roles in the anammox reaction need to be validated. Six novel members of Planctomycetes, divergent from the known genera of anammox bacteria, were also detected. A phylogenetic analysis by Hzo protein sequences revealed the existence of two known genera, i.e., “Candidatus Jettenia” and “Candidatus Anammoxoglobus”, which are rarely captured from marine sediments. Among all ecological parameters investigated, the distribution patterns and composition of anammox bacteria were found to be influenced by salinity, total organic matter, and temperature. The abundance of the anammox bacterial 16S rRNA gene from the sites examined ranged between 3.95×105 and 9.21×105 copies g−1 wet sediment and positively correlated with the median size of the sediment sample.

A Gram-stain-negative, orange-coloured, rod-shaped bacterium, designated strain Th68(T), was isolated from the intestine of flounder (Paralichthys olivaceus). The isolate required sea salts for growth. Gliding motility was not observed. Flexirubin-type pigments were present. 16S rRNA gene sequence analysis indicated that strain Th68(T) represented a distinct phyletic line within the family Flavobacteriaceae with less than 96.1% similarity to members of the recognized genera of the family. The DNA G+C content was 33.0 mol%. The major fatty acids were iso-C(15 : 0), iso-C(15 : 1) G, iso-C(17 : 0) 3-OH and iso-C(15 : 0) 3-OH. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and two unidentified polar lipids. Menaquinone 6 (MK-6) was the only respiratory quinone. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain Th68(T) represents a novel species of a new genus in the family Flavobacteriaceae , for which the name Flavirhabdus iliipiscaria gen. nov., sp. nov. is proposed. The type strain of Flavirhabdus iliipiscaria is Th68(T) ( = JCM 18637(T) = KCTC 32141(T)).

The concept of phase-change memory using chalcogenide glasses dates back to the 1960s, as pioneered by Ovshinsky. [1] Starting from late 1980s, Ge-Sb-Te alloys along the GeTe-Sb 2 Te 3 pseudo-binary line (Group I), such as Ge 2 Sb 2 Te 5 , Ge 1 Sb 2 Te 4 and Ge 8 Sb 2 Te 11 , [2][3][4][5] doped Sb 2þx -Te alloys (Group II), such as Ag-, In-doped Sb 2þx Te (AIST), and alloyed Sb (Group III), [6][7][8][9][10] such as Ge 15 Sb 85 , were identified as suitable PCMs. These alloys were initially used for the rewritable optical data storage industry. [11] More recently, the Ge 1 Sb 2 Te 4 (GST) alloy has been used as the core material for electronic non-volatile memories, [12][13][14][15][16][17][18][19] e.g., 3D Xpoint. Moreover, PCMs can be used for neuro-inspired computing and in-memory computing, [20][21][22][23][24][25][26][27] and could also enable various nonvolatile photonic applications, including memory and computing devices, switches, and displays. [28][29][30][31][32][33][34][35][36] PCMs utilize the significant contrast in electrical resistivity or optical reflectivity between their crystalline and amorphous phase to encode data. [11] The switching between the two logic states is achieved by rapid and reversible phase transitions, namely, SET (crystallization) and RESET (melt-quenched amorphization). In addition to binary storage, multiple resistivity or reflectivity states can be obtained within a PCM cell via partial amorphization (iterative RESET) and crystallization (accumulative SET), enabling multilevel storage [37,38] and neuro-inspired computing applications.
