Bioinspired Fluorescent Nanosheets for Rapid and Sensitive Detection of Organic Pollutants in Water
Detection of organic
pollutants in aqueous media is crucial for
guaranteeing water safety. Conventional methods for organic pollutant
detection suffer from time-consuming operation procedures (on the
order of hours) and expensive devices. Inspired by dog noses, herein,
we constructed self-assembled fluorescent nanosheets for rapid and
sensitive detection of organic pollutants based on the grasp-report
strategy. Tetraphenylethene decorated cyclodextrins (TPE-CDs) self-assembled
into nanosheets with hydrophobic TPE layers sandwiched between two
hydrophilic cyclodextrin layers. The hydrophobic cavity of the outer
cyclodextrin layers grasped and collected organic pollutants, and
subsequently transported them to the TPE layers and quenched the fluorescence
emission of TPE layers. Such nanosheets allowed rapid detection of
xylene (on the order of seconds) at a concentration of 5 μg/L.
With the merits of the ease of synthesis, simple operation, and high
sensitivity, the fluorescent nanomaterials provide a promising candidate
for rapid and sensitive detection of organic pollutants
Controllable Synthesis, Magnetic Properties, and Enhanced Photocatalytic Activity of Spindlelike Mesoporous α-Fe<sub>2</sub>O<sub>3</sub>/ZnO Core–Shell Heterostructures
Mesoporous spindlelike iron oxide/ZnO core–shell
heterostructures
are successfully fabricated by a low-cost, surfactant-free, and environmentally
friendly seed-mediate strategy with the help of postannealing treatment.
The material composition and stoichiometry, as well as these magnetic
and optical properties, have been examined and verified by means of
high-resolution transmission electron microscopy and X-ray diffraction,
the thickness of ZnO layer can be simply tailored by the concentration
of zinc precursor. Considering that both α-Fe<sub>2</sub>O<sub>3</sub> and ZnO are good photocatalytic materials, we have investigated
the photodegradation performances of the core–shell heterostructures
using organic dyes Rhodamin B (RhB). It is interesting to find that
the as-obtained iron oxides/ZnO core–shell heterostructures
exhibited enhanced visible light or UV photocatalytic abilities, remarkably
superior to the as-used α-Fe<sub>2</sub>O<sub>3</sub> seeds
and commercial TiO<sub>2</sub> products (P25), mainly owing to the
synergistic effect between the narrow and wide bandgap semiconductors
and effective electron–hole separation at the interfaces of
iron oxides/ZnO
Mild and Regioselective <i>N</i>‑Alkylation of 2‑Pyridones in Water
A mild and regioselective <i>N</i>-alkylation reaction
of 2-pyridones in water has been developed. Tween 20 (2% w/w) was
added to create a micellar system for improved solubility of starting
materials, which leads to enhanced reaction rates. The protocol demonstrated
a wide substrate scope with good isolated yields (40–94%) for
all of the 24 examples evaluated. High regioselectivity favoring <i>N</i>-alkylation over <i>O</i>-alkylation was observed
for benzyl halides (>5:1), primary alkyl halides (>6:1), and
bulky
and less reactive secondary alkyl halides (>2.4:1)

Plasma Sphingolipids as Potential Indicators of Hepatic Necroinflammation in Patients with Chronic Hepatitis C and Normal Alanine Aminotransferase Level
<div><p>Accurate estimation of hepatic necroinflammation caused by chronic hepatitis C (CHC) is crucial for prediction of prognosis and design of therapeutic strategy, which is particularly true for CHC patients with normal alanine aminotransferase (ALT) level. Recent studies have shown that sphingolipids have a close relationship with hepatitis C virus infection. The present study aimed to identify plasma sphingolipids related to hepatic necroinflammation. We included 120 treatment-naïve CHC patients and 64/120 had normal ALT levels (<40 U/L). CHC patients who underwent liver biopsies were subjected to Scheuer scoring analysis for scope of hepatic inflammation. Plasma sphingolipids were detected by high-performance liquid chromatography tandem mass spectrometry. Our results showed 44 plasma sphingolipids were detected altogether. Of all detected sphingolipids, hexosylceramide (HexCer) (d18∶1/22∶0) and HexCer (d18∶1/24∶0) showed a significant difference among G0/G1, G2, and G3/G4 (<i>P</i><0.05). For identifying hepatic necroinflammation (G≥2), after adjusting other factors, the odds ratio (OR) of HexCer (d18∶1/22∶0) reached 1.01 (95% confidence interval [CI]: 1.00–1.02). Furthermore, the area under the curve (AUC) of HexCer (d18∶1/22∶0) was 0.7 (<i>P</i> = 0.01) and approached that of ALT (AUC = 0.78). However, in CHC patients with normal ALT, HexCer (d18∶1/22∶0) was an independent factor (OR: 1.02, 95% CI: 1.01–1.03) to identify the hepatic necroinflammation (G≥2). HexCer (d18∶1/22∶0) not only showed the largest AUC (0.78, <i>P</i> = 0.001), but also exhibited the highest specificity of all indicators. These results indicate that plasma HexCer (d18∶1/22∶0) is a potential indicator to distinguish hepatic necroinflammation in CHC patients. For CHC with normal ALT, the ability of HexCer (d18∶1/22∶0) to distinguish hepatic necroinflammation might be superior to conventional serum indicators.</p></div
