標題: Electrically-Driven 2D Semiconductor Microcavity Laser 作者: Chen, Zheng-Zhe; Lin, Hsiang-Ting; Chang, Chiao-Yun; Adil, Muhammad; Tsai, Po-Cheng; Kao, Tsung Sheng; Chen, Chi; Lin, Shih-Yen; Shih, Min-Hsiung 摘要: 2D monolayered transition-metal dichalcogenides (TMDCs) are promising materials for realizing ultracompact, low-threshold semiconductor lasers. And the development of the electrical-driven TMDC devices is crucial for enhancing the integration potential of practical optoelectronic systems. However, at the current stage, the electrically-driven 2-D TMDC laser has never been realized. Herein, the first electrically-driven 2-D TMDC microcavity laser have been developed. In this device, an alternating current (AC) generates electroluminescence lasing in suspended monolayered WSe2 integrated on a microdisk cavity. The input-output curve, bandwidth narrowing, and second-order coherence is analyzed to confirm the lasing characteristics at room temperature. The realization of the room-temperature AC-driven 2-D TMDC laser establishes a new area of research on electrically pumped compact lasers and is likely to assist with the implementation of diverse TMDC-based practical photonic devices in the future.

標題: Evolutionary adaptation of anaerobic and aerobic metabolism to high sulfide and hypoxic hydrothermal vent crab, Xenograpsus testudinatus 作者: Chen, Chi; Wu, Guan-Chung; Tseng, Yung-Che; Dufour, Sylvie; Chang, Ching-Fong 摘要: The vent crab, Xenograpsus testudinatus (xtcrab), is adapted to inhabit shallow-water, high sulfide and hypoxic hydrothermal vent. Our previous study revealed sulfide tolerance of vent xtcrabs which sulfide: quinone oxidoreductase (xtSQR) paralogs aid in sulfide detoxification. However, the mechanisms of how xtcrab adapts to high sulfide-hypoxic conditions in the vent area remain to be explored. In the present study, we tested the tolerance of xtcrab to sulfide-induced hypoxia, and investigated their aerobic and anaerobic responses in situ and in the laboratory. Comparisons were made to a non-vent, intertidal species, Thranita danae (tdcrab). We analyzed the several factors related to aerobic metabolism (SQR, cytochrome c [CYTC], complex IV [COXIV]), the product of anaerobic metabolism (hemolymph lactate levels) and glucose levels. Our results showed a higher survival tolerance to hypoxia of xtcrabs than tdcrabs. Hemolymph lactate levels increased more rapidly in xtcrabs than tdcrabs exposed to experimental hypoxia, revealing a rapid induction of anaerobic metabolism in hypoxic xtcrabs. Lactate measurement in xtcrabs returned from aquaria to original capture sites (vent habitats), further assessed the remarkable ability of xtcrabs to rapidly switch on and off their anaerobic metabolism. To assess aerobic metabolism, long-term exposure of xtcrabs to hydrothermal vent habitat increased gill xtCYTC transcripts and protein levels together with steadily enzymatic activity of COXIV. This revealed ability of xtcrabs to maintain functional capacity of aerobic respiration in hypoxia. Phylogenetic analysis showed that xtSQR paralogs in xtcrabs were more distant compared to tdSQR paralogs in tdcrabs. The increase of transcripts and enzymatic activity of gill xtSQR, and co-localization of xtSQR and xtCYTC also contribute to maintain aerobic metabolism by preventing sulfide toxicity on mitochondrial respiratory function. Overall, our study suggests that multiple strategies including detoxification of sulfide by gill xtSQR, and a quick/dynamic switch between aerobic and anaerobic metabolisms may play important roles in the metabolic adaptations of xtcrabs to extreme hydrothermal vent environment.

標題: Relationships between high school students' learning interest, learning motivation, and ocean literacy: a longitudinal study 作者: Tsai, Liang-Ting; Chang, Cheng-Chieh 摘要: This study investigated the trends and correlations between ocean literacy (OL), marine science learning interest (MSLI), and marine science learning motivation (MSLM) in Taiwanese high school students in a three-wave longitudinal survey, with an OL scale used to assess students' MSLI and MSLM. A total of 428 valid responses were collected. The results indicated that the students' OL decreased by the second survey but slightly increased by the third. The MSLM scores exhibited an upward trend, whereas MSLI remained unchanged. A cross-lagged analysis revealed a consistently positive correlation between OL and MSLM across all three waves. Moreover, significant positive correlations between OL and MSLI and between earlier OL levels and later MSLI were observed, indicating OL plays a critical role in fostering MSLI. This study elucidates the associations between OL and MSLI and proposes directions for enhancing future OL education and research.
