Polysaccharide-Hair Cationic Polypeptide Nanogels: Self-Assembly and Enzymatic Polymerization of Amylose Primer-Modified Cholesteryl Poly(l-lysine)
14-05-2013 | Nobuyuki Morimoto; Mio Yamazaki; Junko Tamada; Kazunari Akiyoshi, Langmuir, 2013
In this study, we prepared a new associating polymer, ChMaPLL, by the substitution of the poly(l-lysine) moiety with oligosaccharide amylose primer and cholesterol. ChMaPLL formed positively charged polypeptide nanogels (∼50 nm) via self-assembly in water. The nanogels showed a secondary ...
In situ thermal reduction of graphene oxide in a styrene–ethylene/butylene–styrene triblock copolymer via melt blending
09-05-2013 | Feng You, Dongrui Wang, Jianping Cao, Xinxin Li, Zhi‐Min Dang, Guo‐Hua Hu, Polymer International, 2013
Abstract We report an in situ thermal reduction of graphene oxide (GO) in a styrene–ethylene/butylene–styrene (SEBS) triblock copolymer matrix during a melt‐blending process. A relatively high degree of reduction was achieved by melt‐blending premixed GO/SEBS nanocomposites in a Haake ...
Rationale for the Higher Reactivity of Interfacial Sites in Methanol Decomposition on Au13/TiO2(110)
09-05-2013 | Sampyo Hong; Talat S. Rahman, Journal of the American Chemical Society, 2013
Interfacial and perimeter sites have been known for their high activity in various reactions on supported gold nanoparticles. We find that the higher activity of interfacial sites in Au13/TiO2(110) toward methanol decomposition originates from charge-transfer-induced Coulomb interaction among ...
Structural Studies of the O‐Acetyl‐Containing O‐Antigen from a Shigella flexneri Serotype 6 Strain and Synthesis of Oligosaccharide Fragments Thereof
08-05-2013 | Pierre Chassagne, Carolina Fontana, Catherine Guerreiro, Charles Gauthier, Armelle Phalipon, Göran Widmalm, Laurence ..., European Journal of Organic Chemistry, 2013
Abstract Extensive analysis by NMR spectroscopy of the delipidated lipopolysaccharide of Shigella flexneri serotype 6 strain MDC 2924‐71 confirmed the most recently reported structure of the O‐antigen repeating unit as ...
Conformations of DNA in Triangular Nanochannels
07-05-2013 | Chiara Manneschi; Elena Angeli; Tapio Ala-Nissila; Luca Repetto; Giuseppe Firpo; Ugo Valbusa, Macromolecules, 2013
Despite the widespread use of triangular nanochannels for the manipulation and analysis of DNA, studies on the confining effects induced by these nanofluidic structures on the molecules are still absent. Here, we perform coarse-grained Monte Carlo simulations to study the conformations of DNA ...
Abrasive wear performance and antibacterial assessment of untreated and treated ZnO‐reinforced polymer composite
06-05-2013 | Boon Peng Chang, H.M. Akil, R.M. Nasir, S. Nurdijati, Polymer Composites, 2013
In this work, the response of different filler loading of zinc oxide (ZnO) reinforced ultra‐high‐molecular‐weight polyethylene (UHMWPE) on mechanical, abrasive wear, and antibacterial properties were studied. Two variants of untreated ZnO‐reinforced UHMWPE (U‐ZPE) and treated ZnO‐reinforced ...

Publication date: Available online 30 April 2013Source:Reactive and Functional Polymers Author(s): Qingyang Gu , Zhiqian Jia PVDF microfiltration membranes were modified by γ-ray irradiation induced grafting polymerization of 4-vinyl pyridine (4-VP) and then quaternization by n-butyl ...
Effect of nanocarbides and interphase hardness deviation on stretch-flangeability in 998 MPa hot-rolled steels
06-05-2013 | Author(s): Eun Joon Chun , Hyeonghyeop Do , Seongju Kim , Dae-Geun Nam , Yong-Ho Park , Namhyun Kang, Materials Chemistry and Physics, 2013
Publication date: 15 June 2013Source:Materials Chemistry and Physics, Volume 140, Issue 1 Author(s): Eun Joon Chun , Hyeonghyeop Do , Seongju Kim , Dae-Geun Nam , Yong-Ho Park , Namhyun Kang By performing various laboratory hot-rolling simulation tests, effective rolling conditions ...
Effective mechanical properties of polyvinylalcohol biocomposites with reinforcement of date palm leaf fibers
04-05-2013 | Jyoti R. Mohanty, Sankar N. Das, Harish C. Das, Sarat K Swain, Polymer Composites, 2013
Polyvinylalcohol/date palm leaf fiber (PVA/DPL) biocomposites were prepared by the melt mixing fabrication technique with various proportions of fibers. DPL fibers were chemically modified with the purpose of improving the dispersion and better compatibility with PVA matrix. Different ...
Effect of Alkali Treatment on the Morphology and Tensile Properties of Cordia Dichotoma Fabric/Polycarbonate Composites
03-05-2013 | J. Jayaramudu, G. Siva Mohan Reddy, K. Varaprasad, E. R. Sadiku, S. Sinha Ray, A. Varada Rajulu, Advances in Polymer Technology, 2013
ABSTRACT The newly identified natural fabric from the tree of Cordia dichotoma was coated with polycarbonate. Tensile parameters, such as, tensile strength, Young's modulus, and percentage of elongation at the break of the fabrics were determined using a universal testing machine. The ...
