Remarkably and stable catalytic activity in reduction of 4-nitrophenol by sodium sesquicarbonate-supporting FeO@Pt.

Reasonable design of bimetallic nanomaterials with support is beneficial to improve catalytic performance. This work reports a new kind of sodium sesquicarbonate-supporting FeO@Pt etching FeO@Pt@SiO, which exhibits highly efficient and stable catalytic reduction performance towards 4-NP. Sodium sesquicarbonate-supporting FeO@Pt has an interconnected one-dimensional network structure that provides sufficient channels for mass transfer.

A hydrangea-like nitrogen-doped ZnO/BiOI nanocomposite for photocatalytic degradation of tetracycline hydrochloride.

The effectiveness of photocatalysts can be impacted by the high compounding efficiency of photogenerated carriers, which depends on the morphology of the photocatalyst. Here, a hydrangea-like N-ZnO/BiOI composite has been prepared for achieving efficient photocatalytic degradation of tetracycline hydrochloride (TCH) under visible light. The N-ZnO/BiOI exhibits a high photocatalytic performance, degrading nearly 90% of TCH within 160 min.

Nano zero-valent iron loaded corn-straw biochar for efficient removal of hexavalent chromium: remediation performance and interfacial chemical behaviour.

To improve the poor stability of nano zero-valent iron (nZVI), corn-straw biochar (BC) was used as a support for the synthesis of composites of nZVI-biochar (nZVI/BC) in different mass ratios. After a thorough characterization, the obtained nZVI/BC composite was used to remove hexavalent chromium [Cr(vi)] in an aquatic system under varying conditions including composite amount, Cr(vi) concentration, and pH. The obtained results show that the treatment efficiency varied in the following order: nZVI-BC (1 : 3) > nZVI-BC (1 : 5) > nZVI alone > BC alone.

[Integrated strategy for mechanism of Baitouweng Decoction in treating dampness-heat diarrhea based on urine metabolomics coupled with network pharmacology].

Baitouweng Decoction is a famous Chinese medicinal decoction that has been used to treat diarrhea over thousands of years. In this study, we investigated the effect and mechanism of Baitouweng Decoction in the treatment of diarrhea. Wistar rats were randomly assigned into 4 groups: control group, dampness-heat diarrhea model group(modeling by complex factors including high-sugar and high-fat diet, improper diet, hot and humid environment, drinking and intraperitoneal injection of Escherichia coli), Baitouweng Decoction(3.

A comparative study of Cd(ii) adsorption on calcined raw attapulgite and calcined aluminium hydroxide-modified attapulgites in aqueous solution.

In this study, raw attapulgite and two aluminium hydroxide-modified attapulgites prepared using different aluminium salts were calcined at 600 °C to successfully prepare three novel adsorbents (C-ATP, C-ATP-SO and C-ATP-Cl). The three adsorbents were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) analysis and X-ray photoelectron spectroscopy (XPS). Batch experiments revealed that the Cd(ii) adsorption capacity of the three adsorbents increased with increasing pH, increasing the initial concentration of Cd(ii) in solution, and with longer adsorption times.

Construction of ferulic acid modified porous starch esters for improving the antioxidant capacity.

For exploration of a type of synthetic antioxidant dietary fiber (ADF), porous starch (PS), modified by esterification with ferulic acid (FA) moieties, was synthesized successfully, with different degree of substitution (DS). The ester linkage of FA modified PS was confirmed by C solid-state NMR and FT-IR. XRD analysis showed that starch ferulates had a different crystal structure from the V-type pattern of native starch, suggesting that the starch gelled during the esterification reaction, then re-crystallized into a different structure.

Insights into the gelatinization of potato starch by H NMR.

The gelatinization of potato starch and the effect of NaCl on starch gelatinization were monitored successfully by H NMR spectroscopy. Variable temperature (VT) H NMR measurement, from 316 K to 340 K, was conducted on a suspension of potato starch and deuterium water as well as a mixture of potato starch, NaCl and deuterium water. The hydration level of starch was determined with the increase of temperature.

Inhibition of oil digestion in Pickering emulsions stabilized by oxidized cellulose nanofibrils for low-calorie food design.

Celluloses are renewable and biodegradable natural resources. The application of celluloses as oil-in-water Pickering emulsifiers is still quite limited. In this paper, cellulose nanofibrils (CNFs) with oxidation degrees (DOs) of 52.

Acidolysis-dominated pretreatment elevates distillation yield and impacts composition, antioxidant and antifungal activities of essential oil from seeds.

Proper pretreatment of herbal material containing essential oils (EOs) could enhance its volatile components release through either removing physical barriers or conquering chemical bonds and thereby improve hydrodistillation yield. In this regard, a trial pretreatment including pulverization, enzymolysis, short time microwave irradiation and acidolysis of seeds was integrated into the essential oil (EO) preparation to elevate the EO yield. On the basis of Plackett-Burman design analysis, three parameters (acidolysis duration, HCl concentration of acidolysis and sieving mesh) were significant for the EO preparation.
