Tropical regions are biodiversity hotspots and are well-suited to explore the potential influence of global climate change on forest ecosystems. Bryophytes have essential ecological functions in tropical forest ecosystems, but knowledge of the potential impact of global warming and possible changes in water availability patterns on terrestrial bryophytes is limited. We transplanted eight terres- trial moss species from two elevations (900 and 500 m) to warmer and drier elevations (500 and 100 m) during a halfyear observation period on Tai mo Shan, southern China. The simulated climate change resulted in severely declined health status and marked decrease in growth of the trans- planted species when compared with their performance at the original elevations. Five of the eight selected species survived for six months after being transplanted to the warmer and drier lowlands, though their health status deteriorated severely. Sematophyllum subhumile , Pseudotaxiphyllum pohliaecarpum and Brachythecium buchananii were highly susceptible to changes in temperature and rainfall patterns and might be used as suitable bioindicators. As the tropics are expected to become hotter and drier, terrestrial mosses might be negatively affected or even be at risk of extinction. Bryophytes in the tropics could represent one of the best biological communities to reflect the direct adverse impact of climate change and provide early warning of the biological outcomes induced by ongoing climate crisis.

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(Simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Dual wavelength high-frequency chaos based on nonlinear effects is generated in an erbium-doped fibre ring laser, where tunable filters （TFs） are used to select the wavelength. A receiving fibre laser with an open-loop structure is constructed with identical parameters as the transmitting fibre laser. By tuning the TFs and the fibre delay line in the receiving fibre laser, chaos synchronization has been observed at anyone the two wavelengths after the chaos is transmitted over 1 km. It is of far reaching importance to construct the high capacity chaos communication system.

mo基催化剂在电催化析氢反应（HER）中具有巨大应用潜力.然而,其活性位点的暴露不足、极强的氢吸附能力导致其催化性能未能充分体现.本文在碳布上构筑了mo2N–moSe2异质结（mNS）,以增强mo基催化剂的HER活性.由于mNS中的mo2N具有较低的功函数,能够在异质界面产生内建电场,显著提高了其在HER中电荷转移效率.此外,mNS中原子之间的强电子相互作用优化了mo位点的电子结构,降低了氢吸附能力,进一步增强了其本征催化活性.因此, mNS催化剂产生20 m A cm-2和1 A cm-2的析氢电流密度所需的过电位仅为65和210 mV, Tafel斜率仅为96 mV dec-1.此外, mNS在1 A cm-2电流密度下稳定运行240小时后,形貌、结构和性能均无明显变化.以上研究结果为工业大电流制氢所需的非贵金属基电催化剂的设计和合成提供了新思路.

The effects of the electric field on the electronic structures in electroluminescent polymers were studied with the tight-binding model including electron-phonon interactions plus an applied electric field. It is found that the applied electric field changes both the energy levels and the electronic wavefunctions in electroluminescent polymers: applied field induces two localized electronic states near the midgap, and also polarizes these localized electronic states, so the polarization occurs at weak or moderate fields. In addition, the strong field will dissociate a bipolaron exciton and lead to photoluminescence quenching.
