“…For the purpose of comparison, the base line where there is no band was adjusted to be at the same level for all spectra in each figure. As shown in Figure 5, four bands could be observed that might be assigned to carbon bonded to another carbon or/ and hydrogen including aromatics centered at 285 eV, 59 carbon has a single bond with nitrogen or oxygen located between 286 and 287 eV 60,61 as in ether or alcohol, carbonyl carbon in imide group located between 288.5 eV and 288.8 eV, 59,62 and shake up satellite of phenyl groups from to * located between 290 and 294 eV. 32,63 The decrease in the first band at 285 eV upon BMI incorporation was attributed to lower concentration of this carbon type in BMI than in PSF as shown in Table III.…”

The present work reports a new method of preparing semi‐interpenetrating polymer network (semi‐IPN) membranes through in situ polymerization of bismaleimide (BMI) within polysulfone (PSF). It was found that BMI could be polymerized at ambient conditions in the presence of a proton donor and PSF without the use of an initiator or a catalyst. Chemical structure characterization of these semi‐IPNs by Fourier transform infrared attenuated total reflection (FTIR‐ATR) revealed the possibility of imide cleavage and formation of amic acid when BMI polymerization was continued for a longer time while X‐ray photoelectron spectroscopy (XPS) revealed the protonation of imide nitrogen at shorter polymerization time. It was also found that size of thermoset BMI phase within the PSF thermoplastic has a significant impact on glass‐transition temperature of resulting semi‐IPN. By controlling the thermoset/thermoplastic phase separation of semi‐IPNs through dope composition and formation techniques, gas separation membranes with comparable selectivity and permeance that were up to 12 times higher than corresponding PSF membranes were formed. © 2006 Wiley Periodicals, Inc.

“…Vinnichenko et al (2002) found that, on the surface of stainless steel, Ni migrates into the adsorbed protein layer and the Cr content increased after culturing fibroblast L929 and osteosarcoma SAOS-2. They estimated that the thickness of the adsorbed protein layer on stainless steel as 2.5-6.0 nm after the cells had been removed by trypsin (Vinnichenko et al 2002). Aoyagi et al (2004) analysed the composition of the protein layers on 316L steel and Ti formed with and without L929 cells with time of flight-secondary ion mass spectroscopy (TOF-SIMS) and confirmed the difference in composition of the protein layer with and without cells.…”

Potentiodynamic polarization and impedance tests were carried out on 316L stainless steel with culturing murine fibroblast L929 cells to elucidate the corrosion behaviour of 316L steel with L929 cells and to understand the electrochemical interface between 316L steel and cells, respectively. Potential step test was carried out on 316L steel with type I collagen coating and culturing L929 cells to compare the effects of collagen and L929 cells. The open-circuit potential of 316L steel slightly shifted in a negative manner and passive current density increased with cells, indicating a decrease in the protective ability of passive oxide film. The pitting potential decreased with cells, indicating a decrease in the pitting corrosion resistance. In addition, a decrease in diffusivity at the interface was indicated from the decrease in the cathodic current density and the increase in the diffusion resistance parameter in the impedance test. The anodic peak current in the potential step test decreased with cells and collagen. Consequently, the corrosion resistance of 316L steel decreases with L929 cells. In addition, collagen coating would provide an environment for anodic reaction similar to that with culturing cells.

“…The highly corrosive surroundings and the low tolerance of the body to some dissolution products restrict the materials to be used for implants. These are alloys based on titanium, surgical steel and ceramics [1][2][3][4][5][6][7][8][9][10]. In addition, various polymers such as PTFE such as Teflon, polyethylene and polyetheretherketone [11][12][13] are also applied for implants.…”

“…The implant surface influences particularly the interaction and adsorption of various proteins. Based on the description, the enhancement of surface function on implants is proportional to biological reaction such as cell adhesion and behavior [1][2][3][4][5][6][7][8][9][10][14][15][16][17][18]. To create a surface for desired bioreactions, a promising approach is to start from an existing biocompatible coating.…”
