Dynamic geo‐hydrogeological monitoring‐driven situational awareness for real‐time floor water inrush risk prediction in deep mining

Deep Underground Science and Engineering, EarlyView.
The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

In silico analysis of putative interactions identifies fibroblasts as hubs for cell–cell communication during early regeneration of the zebrafish heart

Developmental Dynamics, EarlyView.
Abstract Background The zebrafish heart regenerates upon injury. During injury response, fibroblasts and endothelial cells accumulate at the site of damage, and cardiomyocyte cell cycle reentry allows cardiac muscle regrowth. It is relevant to understand how the different cell types communicate with each other to coordinate regeneration.

Bimetallic Synergy in Cocatalyst Alloy Nanoparticles for Efficient Photocatalytic Hydrogen Production

EcoEnergy, EarlyView.
A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of
