Investigation of the reaction mechanism of different epoxy resins using a phosphorus‐based hardener
Authors: Varley Russell J. , Liu Weichang , Simon George P. 
Published: January 2006

AbstractIn this work, the fundamental kinetic and structure/property information for a novel phosphorus‐based hardener, bis(4‐aminophenoxy) phosphonate is cured with a range of common epoxy resins such as diglycidyl ether of bisphenol A, tri glycidyl p‐amino phenol and tetra glycidyl diamino diphenyl methane (TGDDM) at various cure temperatures. The rate coefficients k1 and k2 for the primary and secondary amine epoxide addition reactions, respectively, were determined and were found to exhibit a positive substitution effect for the TGAP and TGDDM epoxy resins. Etherification or internal cyclization were shown to be important at higher levels of cure conversion, with these reactions being more significant for the TGAP/BAPP system. Some basic structure/property relationships were established between the glass transition temperature (Tg) and epoxide conversion. The master curve obtained for the superimposition of the various cure temperatures for each epoxy demonstrated the independence of the cure mechanism with temperature. © 2006 Wiley Periodicals, Inc.

Radiation‐induced grafting of acrylic acid and sodium styrene sulfonate onto high‐density polyethylene membranes. I. Effect of grafting conditions
Authors: Zu Jianhua , Wu Minghong , Zhang Jianqiu , Yu Chunhui , Liu Xinwen , Tong Long 
Published: January 2006

AbstractRadiation‐induced grafting of sodium styrene sulfonate and acrylic acid onto high‐density polyethylene (HDPE) membranes was studied by the preirradiation technique. Grafting was carried out using an electronic beam from a 2‐MeV accelerator at room temperature. The effects of the type of solvent, inhibitor concentration, preirradiation atmosphere, monomer concentration, and storage time of preirradiated HDPE membranes on the grafting yield were investigated. Easy control over the grafting yield was achieved by proper selection of the reaction conditions. IR spectroscopy analysis of the grafted membrane confirmed the existence of sulfonate and carboxylic acid groups in the grafted membranes. © 2006 Wiley Periodicals, Inc.

Preparation of core–shell glass bead/polysulfone microspheres with two‐step sol–gel process
Authors: Yujun Wang , Ying Xiong , Fei Chen , Guangsheng Luo 
Published: January 2006

AbstractCore–shell microspheres made from glass beads as the core phase and polysulfone (PSf) as the shell phase can act as an absorbent in the separation process or a supporter for chemical reactions. Based on phase‐inversion principles, a two‐step sol–gel method was developed in this work in which ether was added first and H2O was added second to a PSf‐containing dimethyformamide (DMF) solution to help PSf solidify on the surface of glass beads. The results from scanning electron microscopy, Fourier transform IR, and X‐ray photoelectron spectroscopy showed that a dense layer of PSf (thin to several microns) was coated on the glass beads and the core–shell microspheres were almost monodispersed. The utilization percentages of the glass beads and PSf were high as 100 and 80%, respectively. The thickness of the PSf membrane was calculated to be about 4.3 μm. To obtain well‐monodispersed microspheres, the practical volume ratio of ether to DMF was recommended to be larger than 4.5. The results suggested that the two‐step sol–gel method is a highly efficient process for preparation of glass bead/PSf core–shell microspheres. © 2006 Wiley Periodicals, Inc.

Electrochemical properties of polypropylene membranes modified by the plasma polymerization coating of SO2/acetylene
Authors: Basarir F. , Choi E. Y. , Moon S. H. , Song K. C. , Yoon T. H. 
Published: January 2006

AbstractPolypropylene membranes were modified by the plasma etching of SO2, SO2O2, or SO2H2O, followed by the plasma polymerization coating of SO2/acetylene. The conditions for SO2 plasma etching were optimized by the measurement of the ion‐exchange capacity (IEC) as a function of the plasma‐etching power (10–30 W), gas pressure (40–60 mTorr), and treatment time (15–120 s). For the plasma etching of SO2O2 and SO2H2O, only the pressure ratio (SO2/O2 and SO2/H2O) was optimized under the optimized conditions determined from SO2 plasma etching. Plasma etching was then combined with the plasma polymerization coating of SO2/acetylene, for which the conditions were again optimized by the measurement of the IEC as a function of the plasma power (10–40 W), chamber pressure (50–200 mTorr), SO2/acetylene ratio (15/135–60/90), and treatment time (0–10 min). Next, the electrical resistance and water uptake were evaluated. The modified membranes were also analyzed with scanning electron microscopy, whereas plasma polymer coatings were characterized with Fourier transform infrared/attenuated total reflection. © 2006 Wiley Periodicals, Inc.

Analysis of structural changes in bleached keratin fibers (black and white human hair) using Raman spectroscopy
Authors: Kuzuhara Akio 
Published: January 2006

AbstractTo investigate the influence of bleaching treatments on keratin fibers, the structure of cross‐sections at various depths of bleached human hair (black and white human hair) was directly analyzed without isolating the cuticle and cortex, using Raman spectroscopy. The S–S band intensity existing from the cuticle region to the center of cortex region of virgin white human hair decreased, while the S–O band intensity at 1040 cm−1, assigned to cysteic acid, increased by performing the bleaching treatment. Especially, the S–O band intensity of the cuticle region increased remarkably compared with that of the cortex region. Also, the amide III (unordered) band intensity in the cortex region increased, indicating that some of the proteins existing throughout the cortex region changed to the random coil form. Moreover, it has been found that the S–S band intensity existing from the cuticle region to the center of the cortex region of the virgin black human hair decreased remarkably, while the S–O band intensity increased significantly compared with that of the virgin white human hair by performing the bleaching treatment. From these experiments, we concluded that the melanin granules including metal ions act as a decomposition accelerator for the oxidizing agent, thereby leading to a higher level of disulfide (–SS–) group cleavage in the black human hair compared with that of the white human hair. © 2006 Wiley Periodicals, Inc.

Effect of diethylsulfoxide on the thermal denaturation of DNA
Authors: Markarian Shiraz A. , Asatryan Arpine M. , Grigoryan Karine R. , Sargsyan Hasmik R. 
Published: January 2006

AbstractDNA thermal denaturation has been investigated in aqueous solutions of diethylsulfoxide (DESO) by means of UV‐vis and densimetry methods. It is suggested that, on the one hand, the structural change of entire solutions and, on the other hand, a direct interaction of DESO with DNA are responsible for the observed peculiar behavior. The results obtained were compared with those of dimethylsulfoxide (DMSO), also known from literature © 2006 Wiley Periodicals, Inc.

Naphthalene Amidine Imide Dyes by Transamination of Naphthalene Bisimides
Authors: Langhals Heinz , Jaschke Harald 
Published: January 2006

AbstractDerivatives of naphthalene‐1,4,5,8‐tetracarboxylic acid with amidine structures have been prepared. The light absorption of the bisimide derivatives in the UV region is shifted to the visible for the amidine imides, which also fluoresce with a large Stokes shift. It has been shown how the bisimide–lactam rearrangement can be extended to amidine structures.
Nature of Base Stacking: Reference Quantum‐Chemical Stacking Energies in Ten Unique B‐DNA Base‐Pair Steps
Authors: Šponer Jiří , Jurečka Petr , Marchan Ivan , Luque F. Javier , Orozco Modesto , Hobza Pavel 
Published: January 2006

AbstractBase‐stacking energies in ten unique B‐DNA base‐pair steps and some other arrangements were evaluated by the second‐order Møller–Plesset (MP2) method, complete basis set (CBS) extrapolation, and correction for triple (T) electron‐correlation contributions. The CBS(T) calculations were compared with decade‐old MP2/6‐31G*(0.25) reference data and AMBER force field. The new calculations show modest increases in stacking stabilization compared to the MP2/6‐31G*(0.25) data and surprisingly large sequence‐dependent variation of stacking energies. The absolute force‐field values are in better agreement with the new reference data, while relative discrepancies between quantum‐chemical (QM) and force‐field values increase modestly. Nevertheless, the force field provides good qualitative description of stacking, and there is no need to introduce additional pair‐additive electrostatic terms, such as distributed multipoles or out‐of‐plane charges. There is a rather surprising difference of about 0.1 Å between the vertical separation of base pairs predicted by quantum chemistry and derived from crystal structures. Evaluations of different local arrangements of the 5′‐CG‐3′ step indicate a sensitivity of the relative stacking energies to the level of calculation. Thus, describing quantitative relations between local DNA geometrical variations and stacking may be more complicated than usually assumed. The reference calculations are complemented by continuum‐solvent assessment of solvent‐screening effects.
