Chitosan from Muga silkworms (Antheraea assamensis) and its influence on thermal degradation behavior of poly(lactic acid) based biocomposite films

30-Apr-2016 | Akhilesh Kumar Pal, Ananya Das, Vimal Katiyar, Journal of Applied Polymer Science, 2016

ABSTRACT The research work is focused on extraction of chitin from Muga silkworms (MS) and its conversion into chitosan by chemical treatment process. The extracted amount of chitin and chitosan from MS were obtained ∼8 wt % and ∼7 wt %, respectively. Potentiometric titrations, conductometric ...

Thin film composite forward osmosis membranes with poly(2‐hydroxyethyl methacrylate) grafted nano‐TiO2 as additive in substrate

30-Apr-2016 | Wu Kuang, Zhongnan Liu, Guodong Kang, Dandan Liu, Meiqing Zhou, Yiming Cao, Journal of Applied Polymer Science, 2016

ABSTRACT The poly(2‐hydroxyethyl methacrylate) grafted titanium dioxide nanoparticles were synthesized and added to the substrate of flat‐sheet thin film composite forward osmosis (TFC‐FO) membranes. The hydrophilicity of substrate was improved, which was advantageous to enhance the water flux ...

Iron oxide nanotube film formed on carbon steel for photoelectrochemical water splitting: effect of annealing temperature

29-Apr-2016 | Hongda Deng, Mao‐Chia Huang, Wei‐Heng Weng, Jing‐Chie Lin, Surface and Interface Analysis, 2016

Carbon steels (CSs) were anodized in an ethylene glycol solution containing 3 vol.% H2O and 0.1 m NH4F to coat with nanotube arrays film. The as anodized nanotube arrays film were annealed in argon atmosphere at various temperatures ranging from 250 to 550 °C for 4 h. The morphology and crystal ...

Synthesis and characterization of a biphenyl perfluorocyclobutyl (BP‐PFCB) polyethylene glycol (PEG) blend compatibilizer

28-Apr-2016 | Dakarai K. Brown, Scott T. Iacono, Jean‐Marc Cracowski, Kenneth Christensen, Dennis W. Smith, Polymers for Advanced Technologies, 2016

Polyethylene glycol (PEG) end‐capped trifluorovinyl ether (TFVE) telechelomer was synthesized in one step via esterification of 4‐(trifluorovinyloxy) benzoic acid. The new telechelomer was characterized by attenuated total reflectance Fourier transform infrared (ATR‐FTIR), elemental analysis, ...

Rapid point‐of‐care identification of oral medications in gastric lavage content by ambient mass spectrometry in the emergency room

27-Apr-2016 | Chi‐Wei Lee, Hung Su, Kun‐Da Wu, Jentaie Shiea, Deng‐Chyang Wu, Bai‐Hsiun Chen, Shyi‐Jang Shin, Rapid Communications in Mass Spectrometry, 2016

Rationale Acute poisoning should be handled with high efficiency in order to minimize morbidity and mortality in the emergency room. Unfortunately, history‐taking and physical examination are not always reliable. Mis‐swallowing of oral medications is common in the pediatric group. This study ...

From toroidal to rod‐like nanostructure, a mechanism study for the reversible morphological control on amphiphilic triblock copolymer micelles

26-Apr-2016 | Zhida Wang, Fengman Sun, Shilin Huang, Changfeng Yan, Journal of Polymer Science Part B: Polymer Physics, 2016

ABSTRACT Mechanism of the morphological changes between toroidal and rod‐like nanostructures of P4VP‐b‐PS‐b‐P4VP amphiphilic triblock copolymer micelles has been investigated in aqueous solution. This transition is proved to be highly reversible and tunable upon changing temperature. The ...

How preparation and modification parameters affect PB‐PEO polymersome properties in aqueous solution

23-Apr-2016 | Joachim Habel, Anayo Ogbonna, Nanna Larsen, Simon Krabbe, Kristoffer Almdal, Claus Hélix‐Nielsen, Journal of Polymer Science Part B: Polymer Physics, 2016

ABSTRACT The effect of formation and modification methods on the physical properties of polymersomes is critical for their use in applications relying on their ability to mimic functional properties of biological membranes. In this study, we compared two formation methods for polymersomes made ...

Free and nanoencapsulated vitamin D3: effects on E‐NTPDase and E‐ADA activities in an animal model with induced arthritis

22-Apr-2016 | Karine Lanes Silveira, Leonardo Lanes Silveira, Maria Luiza Prates Thorstenberg, Fernanda Licker Cabral, Livia Gelai ..., Cell Biochemistry and Function, 2016

The effect of vitamin D3 in oral solution (VD3) and vitamin D3‐loaded nanocapsules (NC‐VD3) was analysed in animals with complete Freund's adjuvant (CFA) induced arthritis (AR). For this purpose, we evaluated scores for arthritis, thermal hyperalgesia and paw oedema, as well as histological ...

Synthesis, characterization, and photo‐responsive properties of Y‐shaped amphiphilic azo triblock copolymer

21-Apr-2016 | Renbo Wei, Jinyi Ma, Hongxing Zhang, Yaning He, Journal of Applied Polymer Science, 2016

ABSTRACT In this study, we report the synthesis, characterization, and photo‐responsive properties of a new Y‐shaped amphiphilic azo triblock copolymer composed of two isotropic polyethylene glycol (PEG) blocks and an azobenzene liquid crystalline block. The azo block, with two ending groups ...

Synergistic effect of cellulose nanowhiskers reinforcement and dicarboxylic acids crosslinking towards polyvinyl alcohol properties

21-Apr-2016 | Amit Kumar Sonker, Naveen Tiwari, Rajaram Krishna Nagarale, Vivek Verma, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT In the presented work, a significant increase in the tensile strength of the PVA composite material is reported. The obtained best value of 122 MPa and 14.6% swelling shows the excellent synergistic effect of both crosslinker and reinforcement material. The composite films were ...
