There are many sample preparation methods for heavy metal detection of soil samples, but each has its advantages and disadvantages.Based on the above two pretreatment methods, the detection limit, precision, accuracy and actual soil sample measurement value of mercury detection in soil by atomic fluorescence Cassette Players were compared with atom

Abstract In the context of global aging trends, service innovation targeting older adults is becoming increasingly crucial.Because the traditional focus areas of service innovation have predominantly been design and implementation, a significant gap in the existing literature overlooks the criticality of the testing phase.This oversight is particul

Classical DC-DC converters used in high voltage direct current (HVDC) power transmission systems, lack in terms of efficiency, reduced transfer gain and increased cost with sensor (voltage/current) numbers.Besides, the internal self-parasitic behavior of the power components reduces the output voltage and efficiency of classical HV converters.This
