Abstract:
... Hot dry rock (HDR) geothermal energy is a green and renewable resource, and its efficient development has always been a hot research topic worldwide. Using the natural fracture system of deep HDR as a reservoir not only reduces the difficulty and developmental cost of artificial reservoir construction but also greatly increases the efficiency of water–rock heat exchange. In a study of the characte ...

Abstract:
... The “Gadgil effect” hypothesizes that root associations may slow down decomposition through pre‐emptive competition. In the context of recalcitrant litter decomposition, specifically coarse wood debris, it is uncertain as to what is the relative importance of soil communities associated with living roots when compared to those without roots. Here, it is hypothesized that the presence of live roots ...
