Due to the wide applications of magnetic nanomaterials in biology, pharmacy, and diagnostics, there is an increasing need for controlled transport their small volumes liquids. Here, we designed a simple, high-efficiency, flexible method reversibly oriented superparamagnetic microdroplets with no lost volume by alternating fields. Superhydrophobic surfaces high adhesive force played important role, success also relied on sensitive responsive property microdroplet applied Such...
A quasi-stable threshold voltage (Vt) shift is imparted onto field-effect transistors (FETs) with organic semiconductors and polymer dielectrics. Adjustment of Vt from accumulation mode to zero or depletion demonstrated for both p-channel n-channel FETs, accomplished by applying a the gate prior device operation. Hydrophobic dielectrics dopant-resistant were advantageous. pixel circuit that utilizes this nonvolatile memory element proposed.
CdTe quantum dots show increased yields when incorporated into a temperature-sensitive poly(N-isopropylacrylamide) hydrogel (see Figure). The fluorescence intensities and maximum emission wavelengths are sensitive to external temperature stimuli completely reversible.
A series of thiophene-containing oligomers that are less electron rich than alpha-6T were synthesized, and the thin film morphologies field-effect transistor characteristics evaluated. Phenyl thiazole rings included in many oligomers, a new synthesis perfluoroalkylmethyl-terminated was developed. Desirably low off currents associated with calculated highest occupied molecular orbital energies above ca. 5.0 eV relative to vacuum. Some displayed mobilities 0.01 cm2 (Vs)-1, but there no...
NaYF4:Yb3+/Er3+/polyvinylpyrrolidone (PVP) up-conversion (UC) luminescent nanotubes were synthesized by the electrospinning technique. The diameters of controllable changing voltages. structure and optical properties studied transmission electron microscopy (TEM), scanning (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), photoluminescence (PL) spectra, fluorescence microscope. NaYF4:Yb3+/Er3+/PVP nanocomposites simultaneously possessed UC property, active...
An ultra-facile and rapid colorimetric method was explored to detect Cu<sup>2+</sup> in 100% aqueous solution by using only BPEI.
Solid‐phase extraction based on humic acid bonded silica followed by gas chromatography with electron capture detection was developed to determine fipronil and its metabolites in edible oil. To achieve the best performance, we systematically investigated a series of solid‐phase parameters. Under optimized conditions, method validated according linearity, recovery, precision. Good linearities were obtained R 2 more than 0.9996 for all analytes. The limits between 0.3 0.5 ng/g, recoveries...
Abstract Dispersive liquid‐liquid microextraction has garnered increasing attention in sample preparation due to its rapid and efficient extraction process. In this study, a new terpineol‐based hydrophobic deep eutectic solvent was firstly synthesized by mixing α‐terpineol with 1‐octanoic acid, then applied analysis of phenols from water samples dispersive combined high‐performance liquid chromatography diode array detection. Infrared spectroscopy indicated that hydrogen bonding responsible...
Solvent plays a vital role in the syntheses, purifications, and broad applications of upconversion nanoparticles (UCNPs). In this work, effect various dispersive solvents, including single solvents mixed on luminescence properties NaYF4:Yb3+, Er3+ UCNPs was studied systematically. The differences both (UCL) intensities color outputs were observed when dispersing deuterium oxide, dimethylformamide (DMF), dimethyl sulfoxide (DMSO), ethanol, or water. attenuation excitation emission light...
Phenoxy acid herbicides are widely used that play an important role in improving the yield and quality of crops. However, some research has shown this kind herbicide is poisonous to human animals. In study, a rapid sensitive method was developed for detection seven phenoxy water samples based on magnetic solid-phase extraction followed by liquid chromatography tandem mass spectrometry. Magnetic amino-functionalized multiwalled carbon nanotubes were prepared mixing bare Fe3 O4 nanoparticles...
