As an ideal in vitro model, brain‐on‐chip (BoC) is an important tool to comprehensively elucidate brain characteristics. However, the in vitro model for the definition scope of BoC has not been universally recognized. In this review, BoC is divided into brain cells‐on‐a‐ chip, brain slices‐on‐a‐chip, and brain organoids‐on‐a‐chip according to the type of culture on the chip. Although these three microfluidic...
The purification of C2H4 from C2H6/C2H4/C2H2 mixtures is of great significance in the chemical industry for C2H4 production but remains a daunting task.

Lithium‐Ion Batteries
The electrochemical performance of SiOx/C anode is affected by the match of their working potentials. In article number 2302644, Shang Wang, Yanhong Tian, Andreu Cabot, Lijie Ci, and co‐workers demonstrate that a bidirectional diffusion behavior exists in SiOx/graphite anode due to the working potential mismatch, deteriorating the cycle life of the electrode. This mismatch can...
Silicon oxide (SiOx), inheriting the high‐capacity characteristic of silicon‐based materials but possessing superior cycling stability, is a promising anode material for next‐generation Li‐ion batteries. SiOx is typically applied in combination with graphite (Gr), but the limited cycling durability of the SiOx/Gr composites curtails large‐scale applications. In this work, this limited durability is...
Proton exchange membrane water electrolyzer (PEMWE) is a green hydrogen production technology that can be coupled with intermittent power sources such as wind and photoelectric power.
