Electrical conductivity and tensile properties of block‐copolymer‐wrapped single‐walled carbon nanotube/poly(methyl methacrylate) composites

18-10-2014 | Alejandro Ansón‐Casaos, F. Javier Pascual, Cristina Ruano, Natalia Fernández‐Huerta, Isaías Fernández‐Pato, Juan C. ..., Journal of Applied Polymer Science, 2014

ABSTRACT Poly(methyl methacrylate) (PMMA) composites containing raw or purified single‐walled carbon nanotubes (SWCNTs) are prepared by in situ polymerization and solution processing. The SWCNTs are purified by centrifugation in a Pluronic surfactant, which consists of polyethyleneoxide and ...

Preparation and evaluation of nonphosphate terpolymer as scale inhibitor and dispersant for Ca3(PO4)2, BaSO4, and Iron (III) hydroxide scales

18-10-2014 | Yunyun Bu, Yuming Zhou, Qingzhao Yao, Yiyi Chen, Wei Sun, Wendao Wu, Journal of Applied Polymer Science, 2014

ABSTRACT The polymeric scale inhibition and dispersion agents (PAYS) were prepared by graft copolymerization of acrylic acid, allylpolyethoxy carboxylate (APEY) and 2‐acrylamido‐2‐methyl‐propanesulfonic acid by using ammonium persulfate as a radical initiator in aqueous solution, among which ...

Redox polymer with N,N‐dichlorosulfonamide functional groups as arsenite oxidant in aqueous solutions

18-10-2014 | Daniel Ociński, Ewa Stanisławska, Elżbieta Kociołek‐Balawejder, Journal of Applied Polymer Science, 2014

ABSTRACT A macroporous, styrene‐divinylbenzene polymer with N,N‐dichlorosulfonamide functional groups (SO2NCl2), containing two chlorine atoms with oxidation number +1, have been prepared through the chemical modification of a commercial sulfonic cation exchanger (Amberlyst 15, Rohm and ...

Breathable properties of m‐Aramid nanofibrous membrane with high thermal resistance

18-10-2014 | Young Shin Park, Jong Wha Lee, Young Sik Nam, Won Ho Park, Journal of Applied Polymer Science, 2014

ABSTRACT Electrospinning of m‐aramid in dimethyl acetamide/LiCl solution was investigated to develop thermo‐resistant nanofibrous membranes for breathable waterproof materials. The m‐aramid nanofibers were continuously generated and densely mounted to the membrane without the blockage of the ...

A spherical harmonic transform spectral analysis of a localized surface plasmon on a gold nano shell

18-10-2014 | Dan Berco, Chin‐Kun Hu, Journal of Computational Chemistry, 2014

We perform a study of the localized surface plasmon (LSP) modes of a gold nano shell having a silica core by means of discrete dipole approximation (DDA) and spherical harmonics transform for selected wavelengths. We demonstrate an efficient solution for the near and intermediate field terms by ...

Characterization and quantification of microstructures of a fluorinated terpolymer by both homonuclear and heteronuclear two‐dimensional NMR spectroscopy

17-10-2014 | Salim Ok, Magnetic Resonance in Chemistry, 2014

Fluoropolymers are usually insoluble in organic solvents. Insolubility of fluoropolymers limits basic characterization such as microstructural investigations. In the family of fluoropolymers, terpolymer of tetrafluorethylene (TFE), hexafluoropropylene (HFP), and vinylidene fluoride (VDF), named ...

Processing oxidic waste of lead‐acid batteries in order to recover lead

17-10-2014 | Traian Buzatu, Mircea Ionut Petrescu, Valeriu Gabriel Ghica, Mihai Buzatu, Gheorghe Iacob, Asia-Pacific Journal of Chemical Engineering, 2014

ABSTRACT The main process parameters have been investigated with a relatively new method for lead recovery from oxidic paste. The method consisting in leaching with NaOH and is also useful for processing other secondary resources (volatile dusts resulted from metallurgical extraction of lead ...

Analysis of the transformation behaviors of a Chinese coal ash using in‐/ex‐situ XRD and SEM‐EXD

17-10-2014 | Xiongchao Lin, Caihong Wang, Jin Miyawaki, Yonggang Wang, Seongho Yoon, Isao Mochida, Asia-Pacific Journal of Chemical Engineering, 2014

ABSTRACT Crystal and phase transitions of a Chinese Datong coal ash were evaluated using room temperature X‐ray diffraction (RT‐XRD), in‐situ high temperature (HT)‐XRD, and scanning electron microscope combining energy dispersive X‐ray analysis (SEM‐EDX) as temperature varied from 300 °C to ...

Statistical optimization of culture medium for the overproduction of chicken anemia virus immunogen‐ VP1 protein in a recombinant E. coli for vaccine application

17-10-2014 | Meng‐Shiou Lee, I‐Fen Lin, Guan‐Hua Lai, Yen‐Chang Lin, Ken‐Yuon Li, Asia-Pacific Journal of Chemical Engineering, 2014

ABSTRACT The capsid protein VP1 of chicken anemia virus (CAV) is an immunogen usually to be used when developing the diagnostic kits and subunit vaccines. In this study, a codon‐optimized VP1 gene of CAV was used to express VP1 in Escherichia coli. To establish the best culture medium for VP1 ...
