Co-immobilization of Pseudomonas stutzeri YHA-13 and Alcaligenes sp. ZGED-12 with polyvinyl alcohol–alginate for removal of nitrogen and phosphorus from synthetic wastewater
Nitrogen (N) and phosphorus (P) are the two main factors causing water eutrophication. Immobilized micro-organisms have been widely studied in N and P removal. However, the effects of various immobilizing conditions on the removal efficiency of N and P using immobilized micro-organism beads (IMOBs) remain unclear. Polyvinyl alcohol (PVA) and alginate, as the two frequently immobilizing-used matr...

【Applied Surface Science】Surface modification of poly(styrene-b-(ethylene- co-butylene)-b-styrene) elastomer via photo-initiated graft polymerization of poly(ethylene glycol)
Abstract:
Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer biomedical elastomer was covalently grafted with poly(ethylene glycol) methyl ether methacrylate (PEGMA) via a photo-initiated graft polymerization technique. The surface graft polymerization of SEBS with PEGMA was verified by ATR–FTIR and XPS. Effect of graft polymerization parameters, i.e., monomer concentration, U...

Novel polyethersulfone hybrid ultrafiltration membrane prepared with SiO2-g-(PDMAEMA-co-PDMAPS) and its antifouling performances in oil-in-water emulsion application
To avoid the agglomeration of nanoparticles (NPs) in hybrid membranesand alleviate the leakage of NPs duringthe oily wastewater treatment process,poly(2-(dimethylamino)ethylmethacrylate co-3-dimethyl(methacryloyloxyethyl)ammoniumpropanesulfonate)(PDMAEMA-co-PDMAPS) grafted silica (SiO2) [SiO2-g-(PDMAEMA-co-PDMAPS)]NPs were prepared by grafting PDMAEMA brushes onto SiO2 NPs surface via the-surfac...

Biobased poly(butylene 2,5-furandicarboxylate) and poly(butylene adipate-co-butylene 2,5-furandicarboxylate)s: From synthesis using highly purified 2,5-furandicarboxylic acid to thermo-mechanical properties
To synthesize high quality (co)polyesters derived from 2,5-furandicarboxylic acid (FA), an acetic acid refluxing/pH-swing method was proposed to purify FA. 2-Carboxyl furfural and other impurities were removed completely from FA with this method. Using highly purified FA, biobased polyester poly(butylene furnadicarboxylate) (PBF) and aliphatic-aromatic copolyesters poly(butylene adipat...

Poly(L?lactic acid)-block-poly(butylene succinate-co-butylene adipate) Multiblock Copolymers: From Synthesis to Thermo-Mechanical Properties
Multiblock copolymers poly(L-lactic acid)-block-poly(butylene succinate-co-butylene adipate)s (abbr. P(LLA-mb-
BSA)s) are synthesized via a polycondensation/chain extension/coupling method using binary chain extenders. A poly(L-lactic acid) (PLLA) prepolymer synthesized via direct melt polycondensation of L-lactic acid is rapidly chain extended with a bis (2-oxazoline) to form hydroxyl t...

【Ind Eng Chem Res】Effect of dual reactive compatibilizers on the formation of co-continuous morphology of low density polyethylene/polyamide 6 blends with low polyamide 6 content
The coexistence of two kinds of reactive compatibilizers at the interface in immiscible LDPE/PA6 blends, namely, polyethylene graft maleic anhydride (PE-g-MAH) with a long backbone length and polybutadiene graft maleic anhydride (PB-g-MAH) with a short backbone length, promoted the formation of a flat interface and induced a co- continuous morphology in blends containing 30 wt.% PA6. The relations...

Synthesis of 1D Fe3O4/P(MBAAm-co-MAA) nanochains as stabilizers for Ag nanoparticles and templates for hollow mesoporous structure, and their applications in catalytic reaction and drug delivery
One-dimensional
(1D) magnetic Fe3O4/P(MBAAm-co-MAA) nanochains were prepared by distillation-precipitation
polymerization of MBAAm and MAA in the presence of Fe3O4 nanoparticles
as building blocks under a magnetic heating stirrer, which played two critical
roles: serving as magnetic field to induce the self-assembly of Fe3O4 nanoparticles into 1D nanochains and providing thermal energy to ind...

Biodegradable Microcarriers of Poly(Lactide-co-Glycolide) and Nano-Hydroxyapatite Decorated with IGF-1 via Polydopamine Coating for Enhancing Cell Proliferation and Osteogenic Differentiation
Abstract
In this study, insulin-like growth factor 1 (IGF-1) was successfully immobilized on the poly(lactide-co-glycolide)/hydroxyapatite (PLGA/HA) and pure PLGA microcarriers via polydopamine (pDA). The results demonstrated that the pDA layer facilitated simple and highly efficient immobilization of peptides on the microcarriers within 20?min. Mouse adipose-derived stem cells (ADSCs) attach...
