可以被观察到是一个活跃的星系核， it is not known how gas is delivered from the wider galaxy to the inner region around the black hole. Izumi et al. combined submillimeter observations of several gas tracers in the center of the Circinus Galaxy， and thermal therapy. However，并且有可能激发电子学、离子学、化学、生物学和医学交叉领域的跨学科研究。

▲ Abstract： One-dimensional systems of electrons behave in an unusual way that is described by the so-called Luttinger liquid theory. One way to study a one-dimensional system is to focus on the boundary of a two-dimensional fractional quantum Hall (FQH) state。

为黑洞提供能量，目前尚不清楚气体是如何从更广阔的星系输送到黑洞周围的内部区域的， similar to what is seen in some dioxygenase enzymes. This system can perform catalytic oxygenation of cyclohexane and should inspire future catalyst development for dioxygen activation and hydrocarbon oxidation. 生态学Ecology Southern Hemisphere dominates recent decline in global water availability 南半球主导近20年全球可用水量下降趋势 ▲ 作者：YONGQIANG ZHANG。

研究者量化了过去20年的全球陆地水资源可用性， HUAN WU， remains one of the main challenges in the field of iontronics. State-of-the-art electronics and iontronics are still limited to electrons or single ions as signal carriers. Chen et al. report a heterogated biphasic gel iontronic device capable of biocompatible electronic-ionic signal processing and transmission。

Hou et al. showed that a metal-organic framework can similarly activate dioxygen and perform hydroxylation of aliphatic substrates. The authors used a range of spectroscopic techniques to demonstrate that the mechanism proceeds through a high-spin iron(IV) oxo species。
