Interface interaction between high-siliceous/calcareous mineral granules and model cell membranes dominated by electrostatic force

The characteristics of nano-micron calcite particles/common bacteria complex and its interfacial interaction

“…In the previous project, basic research on the interaction characteristics of common bacteria and mineral particles has been done (Dai et al 2014 ; Zhao et al 2018 ; Chen et al 2021a , b ). Common bacteria can be divided into human normal bacteria, air-common pathogenic bacteria, and soil-resident bacteria.…”

“…Asian dust can cause a significant increase in the abundance of airborne bacteria, and live bacteria transmitted in the dust are protected from UV radiation and can extend their lifespan (Griffin et al 2003 ; Smith et al 2011 ). When there are more particles in the air, more microbes are likely to be found (Aziz et al 2018 ; Chen et al 2021a , b ).…”

The characteristics of nano-micron calcite particles / common bacteria complex and its interfacial interaction

“…After long-term transport in the atmosphere, the abundance of dust-loaded bacteria can be in the range of 1.0×10 6 to 1.6×10 7 /m 3 , and the number of active bacteria can reach 2.5×10 5 -3.8×10 6 /m 3 (Hara and Zhang 2012). In the previous project, the basic research on the interaction characteristics of common bacteria and minerals has been done (Dong et al 2017;Ma et al 2018;Chen et al 2021). Therefore, Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus) were selected as the research objects.…”

“…Therefore, the most efficient devices of functional acoustoelectronics can be built on a wide class of quartz with various impurities. A wide variety of physical properties of crystals is created by nature itself, which in natural conditions creates many different piezoelectric crystals that cannot yet be cre-ated artificially (Kotova et al, 2018;Chen Mulan et al, 2021). This article presents the results of our study of highfrequency (HF) piezoelectric properties and quality factor of electroelastic oscillations of different types of natural quartz in comparison to similar properties of artificial quartz.…”
