Design of Mining Personnel Positioning System Based on Wireless Sensor Network
Advances in Engineering Research, 2014 Underground mining is hazardous due to variable conditions in production so accidents occur frequently. The present monitoring system can no longer ensure its safety. Applying Wireless Sensor Network as monitoring system can improve monitoring efficiency and prevent mining accidents. Based on research of Wireless Sensor Network technology, this article

Adaptive Coordination Engineering for Efficient and Robust H2 Release
Advanced Science, EarlyView.β‐H elimination is a pivotal but challenging step in homogeneous formic acid dehydrogenation reactions due to strict hydride‐metal matching. By using a rationally designed Pd1Ag2 bimetallic system with adaptive Pd1‐Ag2/L2 coordination and formate bridges, it enables boosted formic acid dehydrogenation under ambient air (7.7 times higher than a Pd ...
