Experimental study on the evolution of mesoscopic structure and macroscopic mechanical properties of typical karst fillings soil under dry-wet cycles

Jinan in Shandong Province is a typical karst development zone in northern China. When buildings are constructed above filled karst caves, the water environment of the karst fillings may be altered, and their mechanical properties gradually deteriorate under alternating dry-wet c...

The effect of hybrid models integration sequence: taking Fushun area as an example

Landslide susceptibility zoning (LSZ) is a crucial step in reducing landslide related losses, and its accuracy remains a long-standing research focus. Hybrid models are widely used, but little is known about coupling sequences. Here, we show that the accuracy of hybrid models can...

Mineral Chemistry and Genetic Constraints on Yiyuan Jade, Eastern Qinling Orogen, China

Yiyuan jade, a specific gem-quality jade variety in the East Qinling Orogen, occurs as lenticular and vein-shaped bodies hosted within the dolomite and biotite-quartz marble of the Neoproterozoic Meiyaogou Formation. Based on detailed petrological and mineralogical characterizati...

Multiple Dynamic Covalent Bond Crosslinked Ionic Liquids-Based Hydrogel with Stretchable, Rapid Self-Healing and Antibacterial Activity Properties

The development of antibacterial hydrogel with stretchable and self-healing properties is an urgent problem in the field of biomedical engineering. Herein, a series of hydrogels with antibacterial activity was successfully fabricated using polyvinyl alcohol (PVA), borax, 4-formyl...
