    ( A ) Binary phase map, showing the solubility of NaCTFSI/NaFSI at RT and crystallization behavior at −20°C. Soluble compositions at RT are shown in sky blue, whereas frozen compositions at −20°C are denoted by the capital letter “F.” The hybrid solution at α = 8 and β = 9 is the <t>only</t> <t>composition</t> that remained unfrozen (marked “N” in red). Inset photographs illustrate the crystallization behavior over time (1 to 48 hours) for representative compositions stored at −20°C. h, hours. ( B ) DSC curves of the hybrid solution during repeated heating and cooling cycles between −40° and 60°C at 1°C min −1 . ( C ) OCP variation over time on SS electrodes in 35 m NaFSI, 17.6 m NaCTFSI, and hybrid electrolytes. Inset photos show color differences of a methyl red indicator. ( D ) Potentiodynamic polarization curves on SS electrodes and corresponding FESEM images of SS surfaces after anodic polarization in the respective electrolytes. Scan rate = 1 mV s −1 . ( E ) EIS spectra at various temperatures and the corresponding Arrhenius plot (inset) in the 45.6 m hybrid electrolyte. ( F ) LSV curves of the 45.6 m hybrid electrolyte on SS and Al electrodes at 0.2 mV s −1 (cutoff current = ±10 μA cm −2 ). ( G ) Atomic compositions relative to Al, determined by <t>EDX</t> analysis of Al surfaces subjected to various negative potentials. Abnormally high “O” and “C” contents, arising from the surface oxide layer (Al 2 O 3 ) and surface-adsorbed CO 2 , are excluded.

    The schematic illustrates four interconnected components that together provide a comprehensive assessment of ITN performance. Bioassays are used to determine product bio-efficacy through standardized mosquito exposure protocols. Chemical analysis via HPLC and GC-MS enables quantification of AIs, identification of isomeric forms, and assessment of chemical stability. Surface imaging, using scanning electron <t>microscopy</t> <t>(SEM)/energy-dispersive</t> x-ray <t>(EDX)</t> and Raman spectroscopy, provides insight into the spatial distribution and molecular characteristics of insecticide deposition on net fibers. Video analysis technologies are used to monitor mosquito behavior during exposure, offering dynamic data on contact duration, avoidance, and sublethal responses. These components converge to define the chemical presentation of the insecticide and its bio-efficacy, forming a core metric for comparing ITN performance across products and resistance profiles.
