Metal-organic frameworks (MOFs) with open metal sites (OMSs) have been shown to preferentially adsorb unsaturated hydrocarbons such as C2H4 due the formation of π-complexation. However, adsorption capacity and selectivity might well be dampened under humid conditions because OMSs could easily poisoned in presence water vapor. C2H6-selective adsorbents less hydrophilic environments, on other hand, not only effectively minimize impact humidity separation but also directly produce high-purity...
Porous materials that can undergo pore-structure adjustment to better accommodate specific molecules are ideal for separation and purification.

Charge separation plays a crucial role in regulating photochemical properties and therefore warrants consideration designing photocatalysts. Metal-organic frameworks (MOFs) are emerging as promising candidates for heterogeneous photocatalysis due to their structural designability tunability of photon absorption.

Interfacial charge transfer on the surface of heterogeneous photocatalysts dictates efficiency reactive oxygen species (ROS) generation and therefore aerobic oxidation reactions. Reticular chemistry in metal-organic frameworks (MOFs) allows for rational design donor-acceptor pairs to optimize interfacial charge-transfer kinetics.

Tunnel boring machine (TBM) vibration induced by cutting complex ground contains essential information that can help engineers evaluate the interaction between a cutterhead and itself. In this study, deep recurrent neural networks (RNNs) convolutional (CNNs) were used for vibration-based working face identification. First, field monitoring was conducted to obtain TBM data when tunneling in changing geological conditions, including mixed-face, homogeneous, transmission ground. Next, RNNs CNNs...
