“…The relative slope (m) and standard deviation (σ) values were observed to be 0.0015 & 0.00023 for Pb 2+ , 0.0023 & 0.00042 for Hg 2+ , and 0.0018 & 0.00024 for Cd 2+ . The LOD and LOQ values were calculated as 0.46 & 1.53 ppb for Pb 2+ , 0.52 & 1.74 ppb for Hg 2+ and 0.41 & 1.36 ppb for Cd 2+ , using the proposed poly(LMC‐co‐TMP)HBBP sensor, which was found to exhibit superior LOD and LOQ values for the target analytes compared to existing literature reports, [ 24–33 ] as shown in Table S2, (Supporting Information). The observed value indicates the efficacy/efficiency of the proposed solid‐state optical sensor for the ultra‐trace sensing of the target ions in continuous on‐site monitoring.…”

The article reports on the tailor‐made solid‐state optical sensor through controlled imbuement of an amphiphilic probe onto a dual interwoven macro‐/meso‐porous polymer monolithic scaffold for the selective ocular sensing of ultra‐trace toxic heavy metal ions. The structural/surface morphology of the poly(LMC‐co‐TMP) monolith is customized through the stochiometric inclusion of lauryl methacrylate (LMC), trimethyl propanetrimethacrylate (TMP) and porogenic solvents. The riveting sensing performance of the poly(LMC‐co‐TMP) scaffolds for the target ions arises from the built‐in twofold intermingled porous architects that render voluminous surface area and porosity for the embedding of 2‐((1H‐benzoimidazol‐2‐yl)‐4‐butan‐2‐yl)phenol (HBBP), a chromoionophoric probe. The sensor's unique structural and surface properties endure stable ion‐complexation through color transitions from yellow (blank) to a leafy green, peanut brown, and dark blue for Pb2+, Hg2+, and Cd2+, respectively. The sensor imposes high binding affinity for the target ions, with a linear response range of 0–200 ppb for Pb2+/Hg2+ and 0–300 ppb for Cd2+. The detection limit values are 0.46, 0.52, and 0.41 ppb for Pb2+, Hg2+, and Cd2+, respectively. The sensor's hassle‐free on‐field testing in environmental and synthetic samples reveals excellent data reproducibility (Relative Standard Deviation (RSD) ≤1.97%), with pH‐assisted reliable color transitions for eight regenerative trials, with a response time of 45 s.

The mesomorphic behavior and the miscibility properties of binary mixtures of a new series of Schiff base metallomesogen (MOM) are evaluated by differential scanning calorimetry (DSC) and polarized optical microscopy (POM). Nuclear magnetic resonance (NMR), elemental analysis (CHNX), Fourier−transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) were used to certify the molecular structure of the compounds. The results revealed that the studied mixtures are completely miscible throughout the composition field and exhibit a nematic phase which covered the whole composition range. In the mixtures, the stability of the nematic phase varies continuously, and it is possible to highlight the presence of a eutectic composition with a wide mesogenic stability range.

Cadmium is a toxic pollutant that is harmful to the environment and humans. The purpose of this research was to develop a method for cadmium(II) detection using differential pulse anodic stripping voltammetry (DPASV) using a glassy carbon electrode. The developed method was then applied for cadmium detection in the vegetable samples which is water spinach. The developed method was optimized in several parameters such as potential window, deposition potential, deposition time, and scan rate. The developed method for cadmium(II) detection was also investigated in its analytical performance includes linearity, precision, detection limit, and quantitation limit. The optimum conditions for cadmium(II) detection in 0.1 M KCl using DPASV technique obtained such as potential window from -1200 to -100 mV, deposition potential of -1100 mV (vs Ag/AgCl), and deposition time of 360 s. It was obtained good linearity for cadmium(II) detection using the DPASV technique with an R2 of 0.996. The precision was expressed as %SBR with 0.66%. The detection and quantitation limits for cadmium(II) detection were 0.4206 µM~0.0771 ppm and 0.5525 µM~0.1013 ppm, respectively. The developed method was then applied for cadmium(II) measurement in the water spinach sample and the obtained cadmium(II) concentration in water spinach was 0.2399 mg/Kg.
