Magnesium and copper doped CdS/ZnSe (core/shell) nanoparticles were synthesized through direct chemical solution routes in organic solvent. X-ray powder diffraction (XRD) pattern confirmed the mixing of cubic and wurtzite structures. The Mg or Cu-doped CdS shows the obvious blue shift of photolumimescent spectra due to the replacement of Cd ions with Mg or Cu ions. However, the concomitant presence of Mg and Cu, emission peaks relatively shifts to the red range in comparison with that of Cu-doped CdS. The photoluminescent intensity of CdS:Mg,Cu/ZnSe are much higher than that of the undoped CdS and CdS/ZnSe. The PL intensities were also strongly affected by the presence of octadecylamine and increased more than 4 times. The dopant ions, Mg and Cu, play an important role in energy transfer in the lattice. The results shows that CdS:Mg,Cu/ZnSe NPs give not only the luminescences in various region but also the excellent properties of CdS/ZnSe. (C) 2013 Elsevier B.V. All rights reserved.

Turn Off-On Fluorescent CO2 Gas Detection Based on Amine- Functionalized Imidazole-Based Poly(ionic liquid)

Seong-Soo Lee, Mirkomil Sharipov, Won June Kim, Yong-Ill Lee

Summary: Poly(ionic liquids) (PILs) have been widely used for CO2 capture due to their resemblance to ionic liquids and properties of polymers. In this study, the amine-functionalized poly(vinylimidazole)-based PIL (PVIm-NH2) was successfully prepared and characterized as a chemosensor for CO2 gas detection. The detection limit of PVIm-NH2 in the presence of triethylamine (TEA) was found to be 2.86 x 10-3 M with R2 = 0.9906. The mechanism of PVIm-NH2 generating N-heterocyclic carbenes (NHCs) in the presence of TEA and their reaction with CO2 gas to form a carboxylic acid was investigated. Structural modifications of PIL were also shown to make it a promising candidate for chemosensor applications.

Prediction of phosphate adsorption amount, capacity and kinetics via machine learning: A generally physical-based process and proposed strategy of using descriptive text messages to enrich datasets

Baiqin Zhou, Huiping Li, Ziyu Wang, Hui Huang, Yujun Wang, Ruichun Yang, Ranran Huo, Xiaoyan Xu, Ting Zhou, Xiaochen Dong

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
