Voltammetric dopamine sensor based on three-dimensional electrosynthesized molecularly imprinted polymers and polypyrrole nanowires

Abstract: Three-dimensional structures comprising polypyrrole nanowires (PPyNWs) and molecularly imprinted polymer (MIP) were prepared by electropolymerization on the surfaces of a glassy carbon electrode (GCE). The modified GCE possesses both large surface area and good electrocatalytic activity for oxidizing dopamine (DA), and this leads to high sensitivity. The electropolymerized MIP has a large number of accessible surface imprints, and this makes the GCE more selective. Under optimal conditions and at a working voltage of typically 0.23 V (vs. SCE), the calibration plot is linear in the 50 nM to 100 μM DA concentration range, and the limit of detection is 33 nM. The sensor has been successfully applied to the analysis of DA in injections.

Different Effects of Cognitive Shifting and Intelligence on Creativity

Abstract: The relationship between creativity and executive control has long been controversial. Some researchers view creative thinking as a defocused process with little executive control involvement, whereas others claim that executive control plays a vital role in creative thinking. In this study, we focused on one subcomponent of executive control, cognitive shifting, and examined its relationship with creativity by using latent variable analysis and structural equation modeling. We also analyzed whether this relation was mediated by intelligence. The results showed that: (a) cognitive shifting ability had a positive relationship with creativity, but only on the quantitative aspects (fluency and flexibility); (b) Intelligence had a positive relationship with both quantitative and qualitative aspects (originality) of creativity, and its effect on qualitative aspect was stronger than that on the quantitative aspect; (c) There was a mediating effect of intelligence on the relationship between creativity cognitive and shifting.

MIL-53(Al)/Eu3+ luminescent nanocrystals: Solvent-adjusted shape-controllable synthesis and highly selective detections for Fe3+ ions, Cr2O72− anions and acetone

Abstract: Luminescent aluminum-based coordination polymers, MIL-53(Al)/Eu3+ nanocrystals, were successfully fabricated by a simple mixed solvothermal method without the addition of any surfactants or capping agents. The product was characterized by XRD, SEM, TEM, IR, and EDS technologies. Experiments uncovered that the morphology of luminescent MIL-53(Al)/Eu3+ nanocrystals could be tuned by changing the volume ratio of mixed solvents; and the as-obtained nanocrytals presented shape-dependent fluorescent properties. Sheet-like nanocrystals prepared from the system containing the DMF/H2O/ethanol volume ratio of 20:5:5 (Vtotal = 30 mL) presented the strongest PL emission and the biggest BET surface area. It was found that the as-obtained luminescent MIL-53(Al)/Eu3+ nanocrystals could be prepared into fluorescent probes for the selective detections of Fe3+ and Cr2O72− ions in aqueous systems and acetone in CHCl3 since its emission peak could be quenched by these matters. Simultaneously, the mechanism to cause the fluorescent quenching was discussed.
