A model experimental study of the formation mechanism of internal erosion caves in fractured loess
Shuiwen dizhi gongcheng dizhi, 2023 The formation mechanism of caves in fissured loess at the edge of the loess platform plateau is complex and is closely related to the occurrence of geological hazards such as landslides, which pose a serious threat to the production and life of people in

Journal of Materials Research and Technology, 2021 Erosion is known to cost the oil and gas industry millions of dollars in maintenance and repairs. While velocity, particle size, angle of impact and material properties such as hardness of particle and target are known to affect erosion rate, little is ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
