Association of Normal-Range Hemoglobin A1c Value During Midpregnancy with Adverse Birth Outcomes.

Background: The midpregnancy normal-range HbA1c value and adverse birth outcomes were controversial. To address this lack of data, we examined the associations between midpregnancy normal-range HbA1c value and adverse birth outcomes.

Objective: To evaluate whether an association exists between the midpregnancy normal-range HbA1c value and adverse birth outcomes.

Tuning Emission Wavelength of Polymorphous Crystal via Controllable Alkyl Chain Stacking and Its Vapor- and Thermo-Responsive Fluorescence.

Tuning fluorescence colour of solid-state materials has become a topic of increasing interest for both fundamental mechanism study and practical applications such as sensors, optical recording and security printing. In this work, a fluorescent colour tuneable molecule BA-C16 is rationally designed and facilely synthesized by attaching flexible long alkyl chains to 2-hydroxybenzophenone azine (BA), which shows both aggregation-induced emission (AIE) and excited-state intramolecular proton transfer (ESIPT) characteristics. Compared to BA, the simple introduction of long alkyl chains in BA-C16 leads to an emission wavelength redshift from 542 to 558 nm.

Improving the property of calcium ferrite using a sonochemical method.

Power ultrasonic vibration was applied to the solidification of calcium ferrite (CF) melt in this study. The results indicated that power ultrasound can promote the formation of CF by accelerating the solidification process. Ultrasonic vibration greatly refined the CF grains, resulting the grain size decreased from 1893 to 437 μm.

Effect of ultrasonic vibration treatment on solid-state reactions between FeO and CaO.

In the present study, ultrasonic vibration was applied to the solid-state reaction between FeO and CaO. The effect of the ultrasonic vibration treatment on the formation of CaFeO (CF) from the solid-state reaction was investigated by X-ray diffraction (XRD) and the Rietveld structure refinement method. The results indicated that the solid-state reaction between FeO and CaO was accelerated by ultrasonic treatment (UT), which efficiently lowered the formation temperature of the solid-state CF and increased the quantity formed by enhancing the mass transfer process of the reactions.

A ratiometric fluorescent chemosensor for Al³⁺ in aqueous solution based on aggregation-induced emission and its application in live-cell imaging.

A ratiometric fluorescent chemosensor 1 was developed for the detection of Al(3+) in aqueous solution based on aggregation-induced emmision (AIE). The chemosensor showed the fluorescence of its aggregated state and Al(3+)-chelated soluble state in the absence and in the presence of Al(3+), respectively, and resulted in a fluorescence ratio (I461/I537) response to Al(3+) in neutral aqueous solution at a detection limit as low as 0.29 μmol L(-1).

A facile, sensitive and selective fluorescent probe for heparin based on aggregation-induced emission.

A facile, rapidly responsive fluorescence turn-on probe for heparin with high selectivity and sensitivity was reported in this paper. The probe could aggregate on the negatively charged heparin template through electrostatic interactions and then display intense fluorescence due to its aggregation-induced emission (AIE) characteristics. Under optimal condition, the probe showed high selectivity to heparin over chondroitin sulfate(ChS), hyaluronic acid (HA), dextran (DeX) and other substances, with a linear range of 0.

A ratiometric fluorescent probe for hydrophobic proteins in aqueous solution based on aggregation-induced emission.

A novel fluorescent probe 1 is reported here with ratiometric response to hydrophobic proteins (casein) or proteins with hydrophobic pockets (BSA, HSA) through hydrophobic interaction. Probe 1 underwent deprotonation in aqueous solution at pH 7.4 and emitted blue fluorescence at 436 nm.

Tandem extraction strategy for separation of metallic and semiconducting SWCNTs using condensed benzenoid molecules: effects of molecular morphology and solvent.

Separation of metallic and semiconducting single-walled carbon nanotubes (SWCNTs) is of great importance for SWCNT-based nano-electronics. We propose a tandem extraction strategy for efficient separation of different types of SWCNTs. This strategy is based on chiral angle discriminated adsorption of soluble condensed benzenoid aromatic molecules on SWCNTs, which induce different dispersibility of SWCNTs in various organic solvents.

Dye assisted separation of single wall carbon nanotubes.

In this work, we demonstrate a simple and reliable method for selectively separating single wall carbon nanotubes (SWNTs). This method is based on a preferable adsorption of linear polynuclear aromatic dyes on metallic SWNTs. With different adsorption amount of soluble dyes, the metallic and semconducting SWNTs show different solubility in solvents, hence can be separated.
