Effects of crack inclination and aperture on mechanical properties and fracture behavior of sandstone: an experimental study based on acoustic emission monitoring

The inclination and aperture of rock fractures significantly influence the mechanical properties and crack propagation behavior of rock masses. To investigate the deformation characteristics and crack evolution in sandstone, uniaxial compression tests were conducted on specimens...

Beyond the Dominant Geological Metal(loid): Co-Occurring Metal(loid)s Are Linked to Microbial Assembly and Resistomes in Mercury-Enriched Soils

Abstract High geological background regions are naturally enriched with multiple, typically low bioavailability metal(loid)s. Superimposed mining, smelting, and agricultural inputs create complex yet poorly studied environments. Using metagenomics, we profiled bacterial community...
