Summary: The article investigates the application of three different ligands in coordination polymers, and finds that their photophysical properties differ. One of the coordination polymers shows a high emission property, indicating its potential for the detection of the explosive compound 2,4,6-trinitrophenol (TNP) or picric acid (PA). Calculations show that CPs 2 has the highest sensitivity and selectivity towards TNP, and its ligand has the most favorable π-π stacking interaction with TNP. Additionally, the article examines the correlation between the fluorescence quenching mechanism and the structure and coordination arrangement.

Summary: The curing behavior of cement paste and formation of passive film on iron were studied using electrochemical techniques and X-ray photoelectron spectroscopy (XPS). The open circuit potential of iron was monitored in cement paste with a pH of -13 for 56 days, and the results showed that the iron was kept in a passive state. The results of electrochemical impedance spectroscopy revealed an increasing trend of film and cement paste resistance with curing time. XPS analysis provided evidence that the formation of ferric hydroxide and ferric oxide was efficient in passivating the iron. The iron surface receded from corrosion due to the high-alkaline environment of cement paste and the formation of a passive film.

Summary: This study investigated the corrosion inhibition effects of two ionic liquids, 1-Butylpyridinium chloride (BPC) and 1-Butylpyridinium hexafluorophospate (BPH), on carbon steel during acidization. The weight loss results showed inhibitive performance of 90.0% for BPC and 72.5% for BPH. Electrochemical impedance spectroscopy (EIS) demonstrated that the addition of BPC and BPH increased the values of Rct, with BPC reaching a maximum of 262.4 52 cm2 and BPH reaching 125.4 52 cm2. Other tests and experiments confirmed the presence of an adsorptive layer of BPs and suggested that BPC had better inhibitive performance than BPH.

Summary: In this study, a heterotrimetallic complex VBCMERI was found to have synergistic propensity towards detection of aqueous phase As3+ (iAs and oAs). The chromogenic alteration and fluorogenic enhancement of VBCMERI upon interaction with As3+ (iAs) and AsO2- (iAs) were successfully implemented for monitoring arsenic contamination in groundwater samples and Oryza sp. grains. The accumulating tendency of arsenobetaine (oAs) in aquatic crustaceans (Penaeus sp.) can also be distinguished based on the fluorogenic response. The VBCMERI-AsO2- adduct was efficient in regenerating the VBCMERI sensor selectively in the presence of contaminants like Pb2+, and this reversible behavior was further used to mimic a molecular-level 3-input-2-output logic gate ensemble.
