Summary: An optimal electrode surface structure for the LFEFD Ag/AgCl sensor was suggested based on the sequential AgCl formation process on the Ag wire under constant current. The AgCl formation was observed to start with Ag dissolution and cavity formation on the wire surface, followed by the growth of AgCl deposits primarily along scratch lines. The formation of a network structure with multiple AgCl layers was found to be controlled by the release rate of Ag+ from the wire and the applied current magnitude, leading to improved detection sensitivity and service lifetime for the sensor.

Summary: Composite aluminum foams were fabricated by stir casting and ultrasonic treatment, with the addition of submicron MgAl2O4 generated in situ using different weight percentages of SiO2 precursor. The foams with maximum SiO2 addition showed more uniform pore distribution and better stability. The mechanical properties, including plateau stress and energy absorption, were enhanced with increasing SiO2 addition, attributed to the presence of submicron particles in the microstructure.

Summary: In this study, a TiO2-Ag-AgCl photocatalyst was synthesized using biomimetic mineralization mediated by polydopamine. The photocatalyst showed high efficiency in degrading organic pollutants and disinfecting bacteria in water, particularly against E. coli biofilm. Analysis revealed that reactive oxygen species (ROS), including h+ and & BULL;O-2(-), played a key role in the elimination process. Transcriptomic analysis provided insights into the cellular response to ROS damage, highlighting the upregulation of chemotaxis-related outer membrane genes.
