Abstract Poly(hydroxyalkanoates) are biodegradable and biocompatible polymers suitable for tissue engineering. Fused deposition modeling (FDM) belongs to modern rapid prototyping techniques for the fabrication of scaffolds. In this work, poly(3-hydroxybutyrate (PHB), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) were tested for FDM. Thermal and rheological properties of industrial PHAs were compared with poly(lactic acid) (PLA), whic...

Abstract The adsorption characteristic of polypyrrole decorated chitosan-based magsorbent (MChs/Ppy) for the elimination of cationic crystal violet and anionic methyl orange dye from wastewater were explored. The characteristics of MChs/Ppy were studied by TGA, SEM/EDAX, TEM, BET, FTIR, VSM, and XRD analyses. The performance of MChs/Ppy towards the adsorption of CV and MO was investigated by the batch method. Removal performance was obtained to be 88.11 and 92.89% for CV and MO at the optimum co...

Abstract Chardonnay grape pomace was evaluated as a source of pectin. A central composite design was used in order to determine the effect of pH, extraction time (Et) and liquid: solid ratio (LS) on the yield and uronic acid (UA) content of the pectins extracted using boiling HNO3 solution. The optimized extraction condition to reach the maximum yield and UA was pH = 2.08, Et = 135.23 min and LS = 35.11 ml/g, resulting in theoretical yield of 12.8% and UA of 64.4%. The experimental yield of the ...

Abstract High-pressure homogenization (HPH) is a common physical method used for starch modification. In this study, starch molecular structure in terms of chain-length distribution (CLD) and molecular size is characterized to explore the structural variations during HPH and its internal relations. It is found that: 1) the molecular size is significantly reduced by HPH treatments and further gradually decreases with HPH pressure increasing; 2) HPH degrades the long amylose chains with degree of ...

Abstract Laccases which are considered as “green tools” in biotechnology have potential to degrade toxic contaminants/synthetic dyes present in industrial effluents. The loss in activity and stability of laccases are key challenges faced in their potential industrial applications. Here, laccase from Trametes versicolor (polypore mushroom) was immobilized on Sepharose-linked antibody support to carry out the decolourization of phenol red. This support was prepared by covalent linking of anti-lacc...
Abstract In this paper, the electronspun Polylactic acid (PLA)/TiO2 nanofluids (nfs) fibrous membrane with good toughness, hydrophilicity and antibacterial activities are fabricated by taking full advantages of solvent-free TiO2 nfs with amphiphilicity and ionic conductivity. The resulting PLA/TiO2 nfs fibrous membrane exhibits excellent mechanical performance with a tensile strength and elongation at break of 3.68 MPa and 97.32 MPa at 5 wt% loading, respectively, which is 4 and 8 times higher t...

Abstract Different hydrogels of poly(acrylamide-co-3-acrylamido phenylboronic acid-co-chitosan grafted maleic acid) (P(AM-co-AAPBA-co-CSMA)s) were synthesized using poly(ethylene glycol) diacrylate (PEGDA) as a crosslinker to serve for glucose sensing and insulin delivery. The structure and morphology of the hydrogels, named as CSPBA were studied by FTIR and SEM, while the mechanical properties were tested using dynamic mechanical analysis (DMA) and universal testing machine. The prepared hydrog...

Abstract Cellulose is an abundant feedstock with renewability and biodegradability. However, it is still challenging to manufacture natural cellulose products by environmentally friendly thermoplastic processing methods. Herein, we proposed a green approach for the heterogeneous preparation of thermoplastic cellulose grafted polyurethane (RCP-g-PU) from amorphous regenerated cellulose paste (RCP) via hydroxyl/isocyanate chemistry. First, amorphous RCP was fabricated through dissolving cellulose ...

Abstract Liver injury is a common pathological process, which can result in fatty liver, cirrhosis, fibrosis and even cancer. Polysaccharides isolated from plants have been regarded as an important resource of anti-hepatic lesion due to widely distributed in nature and low toxicity. In order to have a better understand of the protective mechanism on liver function, a comprehensive review of research into plant polysaccharides during recent five years was performed. In total, 66 types of polysacc...

Abstract The ultrasonic-assisted alkali extraction of Typha domingensis stem polysaccharide (TDSPs) was studied using the response surface methodology. The optimal parameters of TDSPs with maximum yields (12.24± 0.08%) were as follows: extraction time 40 min, NaOH concentration 1.5 M and the ratio of water to raw material 25mL/g. The experimental purity of TDSPs was 86.01 ± 0.02. Mineral elements were determined by ICP-AES. The gel permeation chromatography results indicated that TDSPs was a pol...
