Three species of interstitial Collembola in Entomobryidae were identified from South Korean coast. One of them, Sinella (Coecobrya) maritima, is new to science. So far 21 halophilous species in 10 families of Collembola, including the new species in this paper, were reported from the Korean peninsula. 相似文献

ABSTRACT Four new species of the collembolan genus Xenylla, X. convexopyga, X. longistriata, X. dotata and X. marina from Korea are described. X. convexopyga is characterized by an absence of the dorsal seta m3 on Th. II-III. While the other three new species share similarities in dorsal chaetotaxic characters. However, they are dissimilar in the following respects: ventral chaetotaxy, body colour, presence or absence of inner teeth on unguis, the length proportion of abdominal segments and thoracic segments, arrangement of anal papillae and the general shape of apical bulb of fourth antennal segment. As a result of this study, a total of 25 species in 6 genera of Hypogastruridae have been recorded from the Korean Peninsula. 相似文献

The garnet-type phase Li7La3Zr2O12 (LLZO) attracts significant attention as an oxide solid electrolyte to enable safe and robust solid-state batteries (SSBs) with potentially high energy density. However, while significant progress has been made in demonstrating compatibility with Li metal, integrating LLZO into composite cathodes remains a challenge. The current perspective focuses on the critical issues that need to be addressed to achieve the ultimate goal of an all-solid-state LLZO-based battery that delivers safety, durability, and pack-level performance characteristics that are unobtainable with state-of-the-art Li-ion batteries. This perspective complements existing reviews of solid/solid interfaces with more emphasis on understanding numerous homo- and heteroionic interfaces in a pure oxide-based SSB and the various phenomena that accompany the evolution of the chemical, electrochemical, structural, morphological, and mechanical properties of those interfaces during processing and operation. Finally, the insights gained from a comprehensive literature survey of LLZO–cathode interfaces are used to guide efforts for the development of LLZO-based SSBs. 相似文献

14 flavonoids, including flavone and flavonol derivatives, were tested for their anticlastogenic effect against induction of micronuclei by benzo[a]pyrene in polychromatic erythrocytes of mice. When each flavonoid was administered orally, together with intraperitoneally administered benzo[a]pyrene, most flavonol derivatives showed an anticlastogenic effect. The data suggest that the 2,3-double bond and 3,5,7-hydroxyl groups in the flavonoid molecules may be essential to produce anticlastogenic effects against benzo[a]pyrene. Galangin, one of the active compounds, and (-)-epicatechin, a weak one, were administered to mice in order to compare their anticlastogenic effect against 3 different kinds of carcinogens: ethyl methanesulfonate, 7,12-dimethylbenz[a]anthracene, and adriamycin. Galangin showed a stronger anticlastogenic effect than (-)-epicatechin against ethyl methanesulfonate and 7,12-dimethylbenz[a]anthracene. However, there was no significant effect against adriamycin-induced micronuclei by both compounds. Our study indicates that most flavonoids are anticlastogenic agents. Their anticlastogenic effects are apparently independent of their own clastogenic activities. Furthermore, their anticlastogenic activities do not apply universally to all types of genotoxic chemicals. 相似文献

Li metal, which has a high theoretical specific capacity and low redox potential, is considered to the most promising anode material for next‐generation Li ion‐based batteries. However, it also exhibits a disadvantageous solid electrolyte interphase (SEI) layer problem that needs to be resolved. Herein, an advanced separator composed of reduced graphene oxide fiber attached to aramid paper (rGOF‐A) is introduced. When rGOF‐A is applied, F? anions, generated from the decomposition of the LiPF6 electrolyte during the SEI layer formation process form semi‐ionic C? F bonds along the surface of rGOF. As Li+ ions are plated, the “F‐doped” rGO surface induces the formation of LiF, which is known as a component of a chemically stable SEI, therefore it helps the Li metal anode to operate stably at a high current of 20 mA cm?2 with a high capacity of 20 mAh cm?2. The proposed rGOF‐A separator successfully achieves a stable SEI layer that could resolve the interfacial issues of the Li metal anode. 相似文献
