Abstract An alkali lignin/poly (vinyl alcohol) (lignin/PVA) composite nanofiber membrane was fabricated by electrospinning and tested as an adsorbent for efficient Safranine T (ST) adsorption. Effect of lignin/PVA ratios on the morphology and chemical properties of the prepared composite membranes were studied. The influence of initial dye pH, time and temperature on the adsorption performance of composite membranes were investigated, and further evaluated the desorption and recycling behavior. ...

Abstract In this paper, magnetic polyethyleneimine lignin (M-Lignin-PEI) was prepared by a reversed-phase suspension crosslinking method to remove Pb (II) form aqueous solutions. SEM, FT-IR, TGA, XRD and VSM technology were employed to explain their structures. Batch adsorption experiments for Pb (II) were carried out to estimate their adsorption performance. Results showed that lignin successfully grafted with polyethyleneimine and coated on the surface of Fe3O4 with a saturation magnetization ...

Abstract Amaryllidaceae alkaloids are unique benzylphenethylamine derivatives that comprise of more than 600 members with a huge chemical diversity. Most of them showed interesting bioactivities, for instance, galanthamine (GAL) is clinically used for Alzheimer's disease treatment. All Amaryllidaceae alkaloids had been thought to be derived from 4′-O-methylnorbelladine originated from norbelladine catalyzed by norbelladine 4′-O-methyltransferase (N4OMT). Herein we mined the transcriptome dataset...

Abstract Natural resistance associated macrophage protein genes (Nramp) is one of the important candidate genes responsible for regulating immune response against pathogen infection. The aim of the present was to quantify expression of Nramp gene in response to pathogen infection. Here, a Nramp was identified and molecularly characterized from Pelteobagrus fulvidraco (PfNramp). The obtained 3134 bp cDNA fragment of PfNramp comprised a 5′-untranslated region (UTR) of 81 bp, a 3′-UTR of 1403 bp an...

Abstract Water addition was found to enhance the thermal stability of alkylimidazolium–acetate ionic liquids (ILs). Especially in the case of high water content (30–50 wt%), few decomposition products can be observed in the 1H NMR spectra even after treatment for 24 h at 150 °C. On the basis of this finding, lignin treatment of water and acetate IL mixtures (50–90 wt% IL content) were investigated at 150 °C. The addition of water, as opposed to pure IL treatment, can inhibit the lignin depolymer...

Abstract Corn starch was esterified with octenyl succinic anhydride (OSA), in which semidry method assisted with vacuum-microwave treatment was used under the alkalescent condition. The effect of vacuum treatment on esterification was studied. The products were characterized by Fourier transform infrared (FT-IR) spectroscopy, 1H nuclear magnetic resonance (NMR), scanning electron microscopy (SEM) and X-ray diffraction. And the emulsifying properties were investigated with the emulsifying capacit...

Abstract The radioactive iodine from nuclear wastes caused severe environmental contamination and public health concern. Chitosan and montmorillonite as green materials of the favorable adsorptivity were proposed for iodine treatment. Rather than intercalation, the crosslinked chitosan proposedly via Pickering emulsion polymerization was coated by hydrophobical-modified montmorillonite (HMMT) to form the micro-composite of chitosan/HMMT (CTS/HMMT) as the iodide adsorbent of eco-safety, adsorptiv...

Abstract Ethylene gas was introduced into annealed V-type crystalline starches (V-starches). The morphological and structural properties of the inclusion complexes (ICs) were characterized using scanning electron microscopy, light microscopy, X-ray diffractometry, and 13C solid-state nuclear magnetic resonance spectroscopy. The ethylene concentration in ICs annealed at 70 °C and 50% (v/v) ethanol increased from 8.0 to 31.8% (w/w) to 18.1–49.6% (w/w). The controlled release characteristics of ICs...

Abstract Graphene possesses a large surface area and offers high loading capacity for aromatic compounds. However, the load is quickly released in the absence of rate limiting diffusion barrier. In this study, we have explored the electrostatic interaction between polyanionic hyaluronic acid (HA) and cationized reduced graphene oxide (rGO) as a means to develop a reinforced hydrogel matrix. We tested if; (i) degradation kinetics of HA matrix can be modulated in the presence of cationized nanoshe...

Abstract Lignin was extracted from coconut husk via alkaline pulping, either Kraft or soda. The isolated lignin samples were classified as hydroxy-benzaldehyde, vanillin, and syringaldehyde type according to Fourier-transform Infrared Spectroscopy, 1H and 13C Nuclear Magnetic Resonance (NMR) spectra. Soda lignin (SL) showed higher thermal stability and glass transition temperature (Tg) than Kraft lignin (KL) as proven by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC...
