在距离我们数亿公里的地方，有一个充满了神秘的天体，它的影响力横跨了整个太阳系。今天我想给大家介绍一下这颗神秘的星球-木星。木星在太阳系中的地位木星距离地球是相当遥远的，而且距离是不固定的，因为两个行星都在绕着太阳旋转，他们的轨道也不是正圆形。
Abstract:Electrochemistry offers a sustainable synthesis route to value-added fine chemicals but is often constrained by competing electron transfer between the electrode and redox-sensitive functionalities distinct from the target site. Here， we describe an ion-shielding heterogeneous photoelectrocatalysis strategy to impose mass-transfer limitations that invert the thermodynamically determined order of electron transfer. This strategy is showcased to enable decarboxylative trifluoromethylation of sensitive arenes by using trifluoroacetate， an inexpensive yet relatively inert trifluoromethyl group source. An ion-shielding layer， formed by trifluoroacetate anions electrostatically adsorbed on a positive molybdenum-doped tungsten trioxide photoanode， prevents undesired electron transfer between substrates and photogenerated holes. The practicality of the developed method was demonstrated with robust photoanode stability ， a good substrate scope， and scaling capability to achieve 100-gram synthesis by using photoelectrochemical flow cells.
有火山在木卫一上喷发不足为奇，奇的是去年下半年以来，这颗卫星上的火山喷发得既猛烈又离奇。PSI’s Io Input/Output observatory discovers large volcanic outburst on Jupiter’s moon Io。
但在5月18日，NASA却在官网发布了一则有些有些摸不着头脑的新闻:旅行者一号目前运行状态一切正常，可以正常接收和执行来自地球的命令，也能返回科学数据，但却传回了一串神秘的代码，那些本该规律的观测数据变成了随机生成的乱码。
