Summary: An electrochemical sensor based on surface molecularly imprinted polymers (SMIPs) was developed for detecting tetracycline (TC). Mesoporous magnetic nanomaterials (Fe3O4@SiO2@mTiO(2)) with high specific surface area were modified and used as the imprinted support. A magnetic molecularly imprinted polymer (MSMIP) was synthesized using surface-initiated reversible addition-fragmentation chain transfer (SI-RAFT) polymerization. The electrochemical sensor showed a linear relationship between peak current and TC concentration, with a detection limit of 9.16 x 10(-10) mol L-1. Real milk samples could be quickly analyzed using the sensor, with recovery rates ranging from 96.27% to 103.84% when standards were added.

Summary: This study aimed to develop a simple, rapid, and highly sensitive photoelectrochemical (PEC) sensor for the detection of dibutyl phthalate (DBP), a major phthalate plasticizer pollutant in the environment. The sensor utilized a dual identification strategy based on a metal organic framework (MOF) and Cu2O heterostructure, incorporating aptamer recognition mechanism with molecular imprinted technology (MIT). The sensor exhibited highly specific determination of DBP due to the strong light adsorption ability and enhanced photocurrent of the Cu3(BTC)2/Cu2O hybrid under visible light irradiation, as well as the double recognition mechanism of aptamer and MIT. The designed sensor achieved a linear range from 0.1 pM to 1.0 nM and an extremely low detection limit of 0.035 pM under optimal experimental conditions, showing good reliability and practicability in real samples assay. This study extends the application of PEC sensors in the detection of plasticizer contaminants.

Summary: NH4ClO4 exhibits high ionic conductivity of approximately 10-5 Scm(-1) with H+ ions as the probable charge carrying mobile species along with the anion ClO4-. The H+ ions can originate from either the -CH2-CH2- of the PEO polymer chain or the NH4+ of the complexing salt. A wide-line NMR study was conducted to identify the mobile H+ species and investigate its dynamics at different temperatures. It was found that the two types of H+ species exhibit different temperature dependence of NMR linewidths, and the H+ species belonging to NH4+ cation predominantly contributes to the room temperature conductivity.

Summary: Due to increasing energy demand, an alternate source of energy is necessary. This can be achieved through solar cells, with dye sensitized solar cells (DSSC) being a low-cost alternative to costly crystalline solar cells. The efficiency of DSSC is improved by using polymer electrolyte, specifically PVA based solid polymer electrolyte, due to properties such as good ionic conductivity and thin film forming ability. Modifications such as the incorporation of nanosized fillers and the formation of conducting polymer electrolyte further enhance the efficiency and ionic conductivity of DSSC.

Summary: The organic-inorganic metal halide-based perovskite solar cell (PSC) is continuously improving. Recent efforts from different researchers, both experimental and theoretical, have been made to enhance the device performance and stability. In this study, a MAPbI3-based PSC device was simulated to investigate its behavior with variations in the absorber's band-gap and series resistance. It was found that the simulated device exhibited a superior power conversion efficiency (PCE) of 25.76% at a band-gap of 1.3 eV. The device performance was also influenced by changes in the series resistance, with the best response observed under lower resistance. Moreover, the change in quantum efficiency (QE) with variations in the series resistance was also analyzed.
