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.

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.

Benzyl isothiocyanate fumigation inhibits growth, membrane integrity and mycotoxin production in .

The antifungal activity of benzyl isothiocyanate (BITC) against pear pathotype-, the causal agent of pear black spot, and its possible mechanisms were studied. The results indicated that both the spore germination and mycelial growth of were significantly inhibited by BITC in a dose-dependent manner. BITC concentrations at 1.

Linear PVA-DTPA-Gd conjugate for magnetic resonance imaging.

In this study, we report the preparation and characterization of the PVA-DTPA-Gd conjugate as a potential MRI contrast agent (CA). The value and the / ratio were about 5.6 mM s and 1.

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.

Purification, structure and anti-oxidation of polysaccharides from the fruit of Bobr.

In this paper, polysaccharides were extracted from the fruits of Bobr. (NTWP) using a hot water extraction method and extraction conditions were optimized by RSM. The optimal conditions were determined as follows: extraction time 7 h, extraction temperature 60 °C, ratio of water to raw material 15 : 1, and with these conditions, the yield was 14.
